DIESEL FUEL SYSTEM Use No. 2 diesel fuel in the engine of this machine.

The use of other fuels can cause the loss of engine power and high fuel consumption.

In very cold temperatures, a mixture of No. 1 and No. 2 diesel fuels is temporarily permitted. See the following Note.

NOTE: See your fuel dealer for winter fuel requirements in your area. If the temperature of the fuel lowers below the cloud point (wax appearance point), wax crystals in the fuel will restrict the fuel filter and cause the engine to lose power or not start.

Fuel Storage If you keep fuel in storage for a period of time, you can get foreign material or water in the fuel storage tank. Many engine problems are caused by water in the fuel.

Keep the fuel storage tank outside and keep the fuel as cool as possible. Remove water from the storage container at regular periods of time.

Fill the fuel tank at the end of the daily operating period to prevent condensation in the fuel tank.

The diesel fuel used in this machine must meet the specifications as shown below in, “Specifications for Acceptable No. 2 Diesel Fuel”, or “Specification D975-81” of the American Society for Testing and Materials.

Specifications for Acceptable No. 2 Diesel Fuel API gravity, minimum ............................................................................................................................................. 34 Flash point, minimum ............................................................................................................................60°C (140°F) Cloud point (wax appearance point), maximum ...........................................................-20°C (-5°F) See Note above Pour point, maximum ..................................................................................................-26°C (-15°F) See Note above Distillation temperature, 90% point ................................................................................282 to 338°C (540 to 640°F) Viscosity, at 38°C (100°F) Centistokes ......................................................................................................................................... 2.0 to 4.3 Cetane number, minimum .......................................................................... 43 (45 to 55 for winter or high altitudes) Water and sediment, by volume, maximum ..................................................................................................... 0.05%

Install the pin from the top of the lifting motor, lower and remove lifting equipment.

NOTE: If hood strut is not adjusted properly the hood will be damaged.

When a hood is removed and replaced an initial adjustment on the strut is necessary. Adjust between the top of the lift motor adjusting jam nut (1) to the top of the threads (2) to 20 mm (X). With the motor down to its lowest point take a measurement between the left hand side hood bumper and the counter weight, record this measurement (Y). Use the following table to adjust the strut (X).

Put articulation lock in OPERATING position.

STEP 81 If hydraulic reservoir was drained, fill reservoir with 105.7 liters (27.9 gallons) of Case AKCELA Hy-Tran UltraÂŽ fluid.

STEP 82 Fill engine coolant system with a solution of 50% Ethylene Glycol and 50% water. Cooling system capacity is 36.9 liters (9.75 gallons). Install the radiator cap. Fill the coolant reservoir up to the FULL mark on the reservoir.

STEP 83 Connect the batteries, install battery covers, put master disconnect switch in ON position.

STEP 84 Start engine and run the engine at low idle. Run the engine at operating temperature for approximately five minutes to completely mix the Ethylene Glycol an d wat er. Wh en the coo lan t is at o pe ra ting temperature, stop the engine. When engine has cooled, check the coolant level at the reservoir.

WARNING: Hot coolant can spray out if radiator cap is removed. To remove radiator cap: Let system cool, turn to first notch, then wait until all pressure is released. Scalding can result from fast removal of radiator cap.

STALL TESTS During these tests the engine runs at full throttle and works against the torque converter, the hydraulic system, or both the torque converter and the hydraulic system. The results of these tests will show if the cause of poor performance is one or more of the following: (1) engine, (2) torque converter or transmission, and (3) hydraulic system.

INSTRUMENT CLUSTER DISPLAYS 1. With the engine running, press the up or down key and scroll through the information screens and trip screens. The following sequence is using the down key only.

NOTE: Pressing the escape key will return the LCD back to the normal driving screen.

2. Start the engine and run at full throttle.

3. To measure the oil temperature with the instrument cluster:

3. To measure the oil temperature with the instrument cluster:

A. Press the up or down arrow key.

A. Press the up or down arrow key.

B. Stop at the info screen with the temperatures that need to be monitored.

B. Stop at the info screen with the temperatures that need to be monitored are on.

4. Place the declutch switch in the OFF position.

5. Place the automatic switch in the manual mode position. Push down and hold the brake pedal for the remainder of this procedure.

6. Release the parking brake.

4. Hold the bucket control lever in the ROLLBACK position while raising and lowering the lift arms from ground level to full height.

5. Continue this procedure until the temperature of the hydraulic oil is 54° to 57°C (129° to 134°F).

7. Move the transmission control lever to Forward and turn the transmission control lever to 3rd gear.

8. Increase the engine speed to full throttle and run the engine at this speed for 30 seconds.

9. Decrease the engine speed to low idle and move the transmission control lever to the Neutral position for 15 seconds.

10. Repeat steps 7, 8, and 9 until the temperature of the torque converter oil is 82° to 104°C (180° to 220°F).
