BEFORE INSTALLATION
EXTENSION CORD Use only the extension cord that has two-pole receptacles that accept the compressor’s plug. Replace or repair damaged cord. Make sure the extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current that the compressor will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table shows the correct size to use depending on the area of cord and ampere rating. HP

OPERATING THE COMPRESSOR
packing, make sure it is in perfect condition (Fig. 2). 2. Position the compressor on a flat surface or on a maximum permissible inclination of 10°, in a well ventilated place, protected against atmospheric agents. 3. If the surface is inclined and smooth, check if the compressor moves while in operation- if it does, secure the wheels with two wedges on its wheels.
1. Before starting the compressor, check that the electricity supply to the compressor is in accordance to the specification label on the compressors tank (FIG. 8).
FIG. 8
2. Compressor can be switched ON by pulling the plug on the pressure switch (FIG. 9).
4. If the surface is a bracket or a shelf top, make sure it does not fall, securing it in a suitable way.
FIG. 9
5. To ensure good ventilation and efficient cooling, the compressor must be placed at least 1m away from any wall.
6. Connect the Polyurethane air hose with outlet of the compressor
WARNING Take care while transporting the compressor, do not overturn it or lift it with hooks or ropes (FIG. 3).
3. Compressors works on a pressure range of 2 Bar. The default setting of the compressor is max. 8 bar and min. 6 bar 4. Pressure switch automatically switches OFF the compressor when the pressure inside the tank reaches 8 bar and it automatically switches ON again when it reaches 6 bar. Note: The pressure range can be varied with the help of the screw inside Starter unit.

5. Manually push the On/Off button down to switch off the compressor when not in use.

The compressor is capable of producing 8 bar maximum pressure but there are times when the air pressure required is less than the maximum pressure. Air regulator provided at the outlet can be used to regulate the outlet pressure. Steps to set the outlet pressure:
FIG. 10
2. Rotate clockwise to increase the outlet pressure and anticlockwise to reduce the outlet pressure. 3. Push the adjustment knob down to lock the pressure setting.
WARNING Some pressure regulators do not have “push to lock”, therefore simply turn the knob to adjust the pressure.
2. Clean / Replace the filter element a. Pull out the Sponge filter element and soak it into a water bucket and retract and squeeze till all the water content is squeezed out and then reassemble the whole filter unit. b. Replace the sponge Filter element with a new element, if required. MAINTENANCE
ADJUSTING THE PRESSURE RANGE
Before attempting any maintenance jobs on the compressor, make sure of the following
1. Remove the black lid present on the top of the pressure switch cover below the On/ Off switch (FIG. 11).
• Master power switch is in “switched off” position. • Pressure switch and the control unit switches are all off.
Black Lid
• Make sure there is no pressure inside the air tank. Refer “Draining the condensate”.
FIG. 11
2. Unscrew the bolt inside the lid hole and pull out the cover.
OIL CHANGES – TOPPING UP WITH OIL
3. Tighten or loosen the hexagonal bolt using a size 10 spanner depending on the pressure requirement.
• The compressor is filled with synthetic oil.
For Example: If the compressor has 8 bar maximum switch Off limit and 6 bar minimum switch On limit, this can be changed to 7 bar maximum and 5 bar minimum. Remember that the range will always be of 2 bar between the maximum and the minimum level. Note: 1. Clockwise rotation of the hexagonal bolt increases the pressure and anticlockwise rotation will decrease the pressure.
2. Start the compressor to check the maximum switch Off limit then release the pressure to check the switch On limit. Repeat step 1 to reach the desired pressure setting.
• Unscrew the oil drain plug on the oil sump, allow all the oil to flow out, and re-screw the plug (FIG. 14). FIG. 14
Pour oil into the upper hole of the oil sump until it reaches the level indicated on the stick. (FIG 15).
DRAINING THE CONDENSATE 1. Unscrew the drain valve present at the bottom of the air receiver tank (FIG. 12).
FIG. 15
Once a week: check oil level of the pumping element and see if it needs topping up.
FIG. 12
2. Allow all the water to flush out through the drain valve.
3. Screw the drain valve back.
NOTE: Drain valve can also be used to empty the tank.
Do not drain used oil into the sewer or dispose off in the environment. FOR OIL CHANGES
CLEANING OR REPLACING THE FILTER
For operation at ambient temperature in the range -5°C to +40°C, use synthetic oil. The advantage of this oil is that is does not lose its characteristics either in winter or summer.
1. Unscrew the nut on the air filter to disassemble the filter body (FIG. 13). FIG. 13
TYPE OF OIL: Mineral Multi-grade (SAE 15 W40) with 100 hours duty. Synthetic Oil with 500 hours duty. NOTE: It is recommended to change the oil after first 100 hrs of operation.

MAINTENANCE INSTRUCTION INSPECTION SCHEDULE
EVERY 50 OPERATING HRS
MAINTENANCE ACTION
Drain the water condensate collected in the air receiver using the Drain valve. Clean the air filter element (required only when the compressor is used in dusty environment). Check the oil level from the Dipstick and refill up to the max Dipstick level if required.
EVERY 100 OPERATING HRS
Clean the air filter element (even if the compressor is not used Change the lubricating oil if normal lubricating oil is used. Fill the oil only upto the max. Dipstick level.
EVERY 500 OPERATING HRS THERE IS NO OUTPUT
Change the air filter element. Check the operation of the compressor at rated Pressure. Check all the couplers and fasteners for proper tightness. Change the lubricating oil if Synthetic lubricating oil is used.
Fill the oil only upto the max. Dipstick level.

TROUBLESHOOTING PROBLEM
Air losses.
POSSIBLE CAUSE
SOLUTION
This trouble is caused by poor tightening of the check valve.
Discharge all pressure from the tank. Refer “Draining the condensate”
These can be caused by loose joints.
Unscrew the hexagon-head of the valve. Carefully clean both the rubber disk and its seat. Refit all parts accurately. Check all joints by wetting them with soapy water and probing for any leaks.
Compressor not starting.
There is no electric supply
Connect the compressor to the power source.
Power supply is not according to the model.
Use supply according to the data plate.
Power cable extensions are not of adequate diameter or length.
Refer “Extension cord Table”.
Compressor not stopping
If the compressor does not stop when maximum pressure has reached, the tank safety valve may not be working.
Contact the service centre
There is no air output
Air filter may be blocked.
Clean or replace the filter.
