________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

TOWING OR PUSHING A DISABLED MACHINE The machine’s drive propelling pump is manufactured with an adjustable tow valve. This valve prevents damage to the hydraulic system when the machine is being towed/pushed short distances without use of the engine. To access the valve open the left front door panel and locate the valve as shown on top front of the propelling pump. Use a pliers or a 5/16” (8 mm) open end wrench to turn the valve 90 degrees, this disengages the hydrostatic lock between the motor and pump.

CAUTION! The hydraulic propelling pump can be damaged if the machine is towed with the valve in the normal working position (A). Reference the illustrations below for the normal working setting (A) (vertical) and the free wheeling towing setting (B) (horizontal). Note: If the tow valve is left in free wheeling (B) (horizontal) position the propelling pump can’t drive the machine FWD or REV. No damage will result, just re-set valve to the normal working setting (A) (vertical). NOTE: Tow or push machine no faster than a normal walking pace (2-3 mph - 3-5 km/h) and for short distances only. If the machine is to be moved long distances the drive wheel needs to be raised off the floor and placed on a suitable transport dolly.

ENGINE AIR FILTER The engine Air Filter (30) is located in the engine compartment. Check the air filter Service Indicator (58) before each use of the machine. Do not service the air filter unless the indicator is lit.

CAUTION! When servicing the engine air filter elements, use extreme caution to prevent dust and dirt from entering the engine. The engine air filter contains a primary (outer) and a safety (inner) filter element. The primary element may be cleaned twice before being replaced. Replace the safety element every third time that the primary element is serviced. Never try to clean the safety element. To clean the primary filter element, remove the cover from the dust cup end of the canister and pull out the primary element. Clean the element with compressed air (maximum pressure 100 PSI) or wash it with water (maximum pressure 40 PSI). Do not put the element back into the canister until it is completely dry. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

ENGINE OIL Check the engine oil level when the machine is parked on a level surface and the engine is cool. Change the engine oil after the first 35 hours of operation and every 100 hours after that. Use 3.5 quarts (3.3 liters) of any SF or SG rated oil meeting API specifications and suited to seasonal temperatures. Replace the oil filter with every oil change. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

ENGINE COOLANT

CAUTION! Do not remove the radiator cap when the engine is hot. To check the engine coolant level, lift the engine cover (2) and observe the coolant level on the coolant recovery tank (28). If the level is low add a mixture of half water and automotive type anti-freeze. Clean the radiator and oil cooler exteriors by washing with low-pressure water or using compressed air every 100 hours. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

ENGINE MAINTENANCE (100 HOURS) At 100 hour intervals it is recommended that the following service be performed: Change oil and filter, clean and inspect spark plugs, check all engine belts condition and adjustment, check battery charge and level, check cooling system hoses and clamps and check general condition and performance of engine. Note: Reference the separately supplied Ford Maintenance and Operators manual for more detailed service data.

SWEEPING SYSTEM ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

FUNCTIONAL OVERVIEW The 2060 / SR 1800 sweeper has a forward-throw or dustpan designed sweeping system. In a forward throw design the broom is made to rotate in such a direction that it will sweep the dirt and debris forward into a front-end hopper. The broom is driven by a drive lug assembly, which is a lug mounted on a hydraulic motor, located on the left side of the broom housing. The right side of the broom is mounted to an idler hub assembly, which swings out of the way to allow for easy broom removal. The drive and idler assemblies are connected by a hex arm weldment, this arm is connected through a linkage to the broom lift lever, which raises and lowers the broom. A side broom is used to sweep debris from edges or curbs into the path of the main broom. A hub mounted to a hydraulic motor drives the side broom. The motor is mounted on a weldment that will allow for the correct side broom angle adjustment. The side broom is raised and lowered by a cable that is connected at the side broom lever, runs through three pulleys and is connected at the side broom weldment. The cable and pulleys are accessible by removing the right side hopper panel. The main broom and side broom are driven by hydraulic motors. Electrically activated control valves control the hydraulic flow to the motors. The main broom solenoid (L3) is energized when the main broom switch (S13), a NC switch is not activated. The side broom solenoid (L4) is energized when the side broom switch (S14), a NC switch is not activated. The main and side broom motors will only operate if the hopper dump door interlock switch (S12) is closed. If the hopper dump door is closed, or if the hopper is raised, the interlock switch (S12) will open the circuit to S13 and S14, not allowing the solenoids L3 and L4 to energize, and will light up the Dump Door Indicator Light. The first accessory gear pump hydraulically drives the two motors. When L3 and L4 are not energized the hydraulic oil will bypass the motors. The relief valve for the system is located inside the same block as the (L3) main broom solenoid valve. This relief valve is set to open at 2500 PSI. _

MAIN BROOM MAINTENANCE Since the Main Broom Motor always turns in the same direction, the bristles on the broom eventually become curved, reducing sweeping performance. Sweeping performance can be improved by removing the broom and turning it around (end-for-end). This procedure, known as “rotating” the main broom, should be done once every 30 hours of operation. The main broom should be replaced when the bristles are worn to a length of 2-1/2 inches (6.35 cm). The main broom stop must be re-adjusted when the broom is replaced. NOTE: The machine should be stored with the Main Broom in the raised position.

WARNING! The engine must not be running when performing this procedure. To Rotate or Replace the Main Broom... 1 Turn the Ignition Key Switch (52) OFF. 2 Put the Main Broom Raise / Lower (ON / OFF) Lever (53) in the DOWN position. 3 Open the Main Broom Access Door (15). 4 Remove the large T-Bolt from the side of the broom idler arm. Pivot the idler arm assembly out of the main broom core. 5 Pull the main broom out of the broom housing and remove any string or wire wrapped around it. Also inspect the skirts at the front, back and sides of the broom housing. The skirts should be replaced or adjusted if they are torn or worn to a height of more than 1/4 inch (6.35 mm) off the ground. 6 Turn the broom around (end-for-end) and slide it back into the broom housing. Make sure that the lugs on the broom drive hub (left side) engage the slots in the broom core. 7 Swing the idler arm assembly back into the broom core and re-install the T-Bolt that holds the idler arm in place. 8 Close and latch the Main Broom Access Door (15). To Adjust the Main Broom Height... 1 Drive the machine to an area with a level floor and set the parking brake. 2 Pull the Main Broom Raise / Lower (ON/OFF) Lever (53) back and slide to the left and up to lower and start the main broom. DO NOT move the machine. 3 Let the main broom run in place for 1 minute. This allows the broom to polish a “strip” on the floor. After 1 minute, raise the broom, release the parking brake and move the machine so that the polished strip is visible. 4 Inspect the polished strip on the floor. If the strip is less than 2 inches (5.08 cm) or more than 3 inches (7.62 cm) wide, the broom needs to be adjusted. 5 See Figure 1. To adjust, loosen the Handle (A) and slide the Stop Bracket (B) up or down to lower or raise the Main Broom. The farther the Lever (5) travels up in the slot, the lower the Main Broom will be. Tighten Handle (A) after adjusting the position of the Stop Bracket (B). 6 Repeat steps 1-5 until the polished strip is 2 inches (5.08 cm) wide. The width of the polished strip should be the same at both ends of the broom. If the strip is tapered, move the machine to a different area and repeat steps 1-5. If the polished strip is still tapered, see broom level adjustment.

FUNCTIONAL OVERVIEW

+ 12V

BLK

ORN

Hopper System A hopper mounted on the front of the machine is used to collect debris. A litter door is located on the front of the hopper to allow the operator to throw large debris that cannot be swept into the hopper. The hopper broom opening has a dump door that is open when sweeping and closed when raising the hopper. A hydraulic cylinder is used to open and close the dump door. A larger cylinder is used to raise and lower the hopper. The back gear pump of the auxiliary pump runs the two cylinders. The hydraulic oil flows through the priority divider to a directional control valve. The directional control valve has two switches built into it, the hopper switch (S15) and the dump door switch (S16). When the dump door lever is moved to either the open or closed position, (S16) will energize the directional by-pass solenoid (L1) and allow oil flow to the directional control valve. When the hopper lever is moved to the up position (S15) will energize (L1) and oil will flow to the directional control valve. If the hopper lever is moved to the down position the interlock relay (K3) will be energized and open the circuit to (S16) and not allow the dump door to be moved. The hopper/dump door interlock switch (S12) will open when the dump door is closed or the hopper is up, de-energizing the door indicator light relay (K6) and opening the circuit to the broom switches. The relief valve for the hopper hydraulic system is located in the directional control valve and is set to open at 2400 PSI.

Dust Control System A dust control system is used to contain and filter the dust that is created when sweeping. In general, the dust control should always be on when sweeping except when there is water on the surface being swept. A hydraulic impeller motor with a fan mounted on it is used to create airflow through the hopper system. As the air moves through the hopper the dust is lifted and then trapped in the filter. The filter assembly has a shaker motor mounted on it that is used by the operator to clean the filter when the machine is in use. Hydraulic oil flows to the impeller motor from the front gear pump of the auxiliary pump. The dust control/shaker switch S7 is used to energize the dust control solenoid L2 in the on position or the shaker relay K2 in the momentary position. There is an optional hopper temperature switch S6, which will open if the hopper temperature exceeds 140° F, and break the circuit to L2 while lighting the temperature indicator H5. The shaker motor has an optional timer E1 that will keep the coil of K2 energized for fifteen seconds when S7 is turned off.

STEERING SYSTEM ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

FUNCTIONAL OVERVIEW The 2060 / SR 1800 has a single rear drive wheel mounted on a steering spindle. The spindle shaft goes through a rack and pinion steering box. The pinion gear is on the spindle shaft and a hydraulic cylinder moves the rack. The cylinder and steering box are located under the rear center console. A hydraulic steering unit, with the steering wheel mounted to it, controls the rack cylinder. The steering unit runs off the second gear in the auxiliary pump, the oil flows through a priority divider that divides the pump output and reduces the oil flow to two gpm for the steering system. There is a check valve built into the steering unit that allows for manual steering if there is no hydraulic oil flow to the unit. The relief valve for the steering system is located in the priority divider block and is set to open at 1500 PSI.

BRAKING / FRONT WHEEL SYSTEM ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

BRAKE ADJUSTMENT The machines brake system employees a combined foot operated pedal and a hand parking brake lever assembly. A common link weldment controls the input to a horizontal brake balance bar that operates the two front wheel brake assemblies. To adjust the brakes: 1 The brake adjustment is normally done with the parking brake lever. The parking brake lever should be adjusted so it firmly holds its (locked park) setting without easily being released. 2 To adjust the parking brake, turn the handle Knob (A) (Figure 1) on the end of the lever clockwise to increase the brake locking force. NOTE: If the knob adjustment is inadequate to firmly hold the brake setting, this indicates the need to inspect the brake shoes and service if there is excessive wear. 3 The foot pedal normally does not need regular adjustment. The brake pedal should have about 2-2 1/4 inch of free play before the brakes engage. If the foot pedal exceeds this distance, with the parking brake adjusted, follow the steps below. 4 Raise and support hopper. Turn engine off and remove key. 5 See Figure 2. Adjust Clevis (B) evenly on both wheels until foot pedal has 2-2 1/4 inch free play before the brakes engage. 6 After adjustment of either the pedal or parking brake lever always check the other components for proper operation and test-drive the machine.

Hydraulic system The heart of the hydraulic system is the hydraulic pump assembly mounted on the back of the engine. This pump is directly coupled to the engine crankshaft and actually consists of two separate pumps, a propulsion pump and an accessory pump. The propulsion pump is a variable displacement piston pump used to drive the wheel motor only. The pedal in the operator’s compartment uses a cable to move an arm on the side of the propulsion pump. The position of this arm determines the stroke of the pistons in the pump, thereby controlling the volume and direction of the oil flowing to the wheel drive motor. The accessory pump is mounted on the back of the propulsion pump. This pump provides the oil flow to power all the other hydraulic systems on the machine. The 2060 / SR 1800 utilizes a dual gear accessory pump to provide two different flow rates to two different hydraulic circuits. Since this pump is also directly coupled to the engine crankshaft (through the propulsion pump), the volume of oil delivered by the pump will be determined by the speed (RPM) of the engine. Maintaining the proper engine speed is essential for performance from the hydraulic system and the machine in general. If the engine runs to slowly, the accessory pump will not provide the proper oil flow to run the motors at the correct speed and the machine will not perform properly. If the engine runs to fast the pump will deliver too much oil, causing excessive system pressure and possibly damaging the system components. The 2060 / SR 1800 uses a fuel injection system, for both gas and propane models, that will control the engine speed. See the ENGINE SYSTEM section of this manual for further information.

TROUBLESHOOTING GUIDE Accurate measurements are the key to troubleshooting a hydraulic system. Once measurements are obtained, they can be compared with specifications to analyze a problem. To troubleshoot the hydraulic system it is possible to use tachometers, flow gauges or pressure gauges. The most convenient method is to check motor RPM with a digital tachometer. The information below should be used to check for proper motor RPM, hydraulic oil flow or proper relief valve settings. The readings are nominal figures and there will be variations due to manufacturer tolerances and system oil temperature. If any reading varies greater than 20% there will be a noticeable loss of performance and should be corrected.

FUNCTIONAL OVERVIEW Drive pedal system The drive pedal has a cable connected to a Hydroback centering assembly that is adjusted to return the forward/reverse drive pedal to the neutral position. This device uses a heavy spring enclosed in a plastic container to return the pump arm to its center of travel. The result is no hydraulic oil pumped to the drive motor (neutral) allowing for safe machine operator control. There is an additional cable that runs from the hopper to a weldment mounted by the propulsion pump arm. When the hopper is raised the cable will move the actuator weldment, which limits the amount of travel the propulsion pump arm can move. The purpose of this design is to not allow the machine to be operated at full speed with the hopper in the raised position. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

Loosen cable connector Nuts (D) and remove cable from mounting bracket. Pull cable end through opening, toward the rear of the machine. Open the left front service door, lift and move circuit breaker assembly to access the propulsion pump linkage and remove Cotter Pin (E) and Pin (F) from Clevis (G). Loosen lock nut and remove Clevis (G) and lock nut from cable. Loosen the two connector Nuts (H) and remove Cable (I) and Hydroback (J) from Mount (K). Pull Hydroback and cable assembly through the machine opening. NOTE: If installing a new cable you may want to tape it to pedal end of the cable and use the old cable to feed the new cable through opening. To separate the Hydroback from the cable, hold Hydroback and unthread the rear swivel fitting from the cable conduit. The hydroback spring housing can now be unthreaded from the cable end. NOTE: To overcome a housing that may be difficult, double nut the cable ends to stop the cable from spinning then grip the smaller metal housing with locking pliers and unthread (ccw).

WARNING! For correct neutral centering operation, install the Hydroback on the output end of the push-pull cable. 11

Install the new Hydroback/cable assembly in reverse order.

CAUTION! After installing or servicing the Hydroback or drive pedal cable follow the steps in the Hydroback/drive pedal neutral adjustment section. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

HYDROBACK DRIVE PEDAL NEUTRAL ADJUSTMENT When servicing the drive system always check for any machine creeping (movement) in the neutral position. The machine must not move in either forward or reverse after the drive pedal is released. If creeping is experienced the neutral position on the Hydroback must be adjusted.

Mount the (3) gauges (H, I & J) in the holes that you cut in step 3 as shown in Figure 2, 3 or 44. Make sure the gauges are orientated as shown. Install the (3) (L) Terminal Tabs on the Black Wires for each gauge light. Install the (A, B, C, E & Q) Wire assemblies onto the gauges as shown in Figure 2, 3 or 4 respectively. When installing the wire assembly (E) be sure to connect the smaller of the two ring terminals to the Oil Pressure Gauge. When installing the wire assembly (Q) (only used on diesel machines) be sure to connect the smaller of the two ring terminals to the Water Temperature Gauge. Wiring diagrams are also provided on the last page of this instruction sheet. Note: Wire assemblies (B) and (C) do not have to be wired exactly as shown in the wiring diagrams (as demonstrated in Figures 2 & 3) as long as wires are all connected to the proper terminal of each gauge they will work. Figure 2 reflects a Propane Model. A Gasoline and Dual Fuel are wired the same this is shown in Figure 33. Figure 4 shows the Diesel wiring. The Black Wire (S) from the wiring harness will not be connected to anything in the case of propane machines. You must find this wire and connect it to the middle terminal (grd) of one of the new gauges from the kit. Also on the propane model, the BLU/BLK Wire (T) from the wiring harness will not be connected to anything. Once you have installed the (3) (L) Terminal Tabs and the Wire Assembly (C) (C), this wire can be connected to the tab end of Wire Assembly (C) (C). Next on propane models locate the VIO wire (W) from the harness, it will not be connected to anything. Connect the wire (W) to the “II ” terminal of the Oil Pressure Gauge. Note: On gas, dual fuel, and diesel machines wire (W) is already connected to the fuel gauge and it should remain there. Wire Assemblies (A & B) each have (4) connectors on them. The propane model will only require that (3) of these connectors be used on each of these assemblies because of the lack of a fuel gauge. The fourth connector on each wire can either be cut off or left hanging loose. On all models except the diesel, find the VIO/BLK Wire (U) going to one of the indicator light connectors. Cut this wire and install the Receptacle Tab (K) on it. Then connect this wire to the VIO/BLK Wire (D) previously installed on the Water Temp Gauge. The White Wire (E) should then be routed into the engine compartment and around the back of the engine so it reaches the side of the engine where the oil sender is located. The WHT/BLK wire (Q) should then be routed into the engine compartment to the back of the engine so it reaches where the new temperature sender will be installed. The control panel and console can be re-installed at this point.

Open the left side engine compartment door. Disconnect the battery. See Figure 6. Lift up on the circuit breaker assembly to remove it. Check the diameter of the upper left hole, it should be .484” (12.3mm) in diameter. If necessary drill the hole to a diameter of .484” (12.3mm). This is to accommodate for the 30 Amp Circuit Breaker (D). Mount the Circuit Breaker (D) to the panel in the hole described above. Then install Boot Reset Button (N) to circuit breaker. Install Relay (E) to the panel (in one of the open spaces) using Screw (W) and Nut (X) as shown. Plug the socket (plastic box) end of Connector Assembly (R) into the Relay (E). Locate the existing 15 Amp Circuit Breaker (F3) and disconnect the orange wire going to it. Slide the small hook on the end of the orange wire from Connector Assembly (R) into the tab terminal of the orange wire that was going to the Fuse (F3). Place the two orange wires back onto the tab of (F3). Connect the red wire with the ring terminal to one of the terminals on Circuit Breaker (D). The black wire (with a ring terminal end) of Connector Assembly (R) goes to a common ground near the horn. Install the Wire Assembly (G) (red wire with a ring terminal on each end) between the positive terminal of the starter motor (currently three red wires going to this terminal), and the open terminal of Circuit Breaker (D). Feed the long red wire of Connector Assembly (R) along main harness, through the large hole in wall of the machine, then move it up toward the left front corner of the cab.

Insert the red wire into the cab, through the hole (drilled in step one) and Grommet (I). Use Connector (T) to splice together the long red wire to the only wire sticking out of the cab harness, near the red wire. Crimp the Connector (T) to fasten the two wires together. Use a few of the supplied cable ties to secure the wiring out of the way and away from any moving parts. Reconnect the battery and close the left side engine compartment door and test the machine for proper operation. With use, the side broom will wear. Adjustments can be made for a worn broom so that the proper portion of the broom is touching the floor while sweeping. If the side broom doesn’t drop low enough and you have reached the down limit of the actuator, you can adjust the OUT position of the actuator nut. The actuator can be adjusted by following steps A through D. A Follow steps 4 – 6 to gain access to the actuator. B Run the actuator nut to its IN limit. Remove Adjuster Cover (shown in Figure 3) to adjust its OUT position. C To increase the travel of the drive nut, turn the adjuster clockwise. Note: Use a 5/16” wrench to turn the adjuster. Each click of the adjuster will change the nut travel 1/16” (1.6mm). Turning the adjuster counterclockwise reduces the amount of travel. D After checking that the drive nut limits are set correctly, replace the adjuster cover.
