Maintenance

NOTE: Any service procedure not covered in the

maintenance schedule should be performed by

qualified service personnel.

The air compressor should be turned off, unplugged

from the power source, air bled from the tank and

allowed time to cool before any maintenance is

performed.

Check the safety valve by performing these three steps:

1. Plug the compressor in and run until shut-off

pressure is reached.

2. Wearing safety glasses, pull out on the safety valve

ring to release pressure from the tank.

3. The safety valve should close automatically at

approximately at 40-50 PSI. If the safety valve does not

allow air to be released when you pull out on the ring, or

does not close automatically, it must be replaced.

Do not attempt to remove or adjust the safety valve.

From time to time, the air filter needs to be removed and

cleaned.

1. Turn the air compressor off.

2. Unplug the air compressor.

3. Turn the air filter cover counterclockwise to remove.

4. Remove air filter from air filter housing.

5. Blow compressed air through the air filter for

10-15 seconds.

NOTE: The motor will automatically restart without

warning if the unit is left plugged in to an outlet with the

Auto/Off switch in the on position.

To ensure efficient operation and longer life of the

air compressor unit, a routine maintenance schedule

should be followed. The following schedule is geared

toward a consumer whose compressor is used in a

normal working environment on a daily basis.

This compressor is equipped with an automatic reset

thermal overload protector which will shut off motor if it

becomes overheated. If the thermal overload protector

is actuated, the motor must be allowed to cool down

before start-up is possible.

For more details, see Troubleshooting Guide (page 7).

1. Turn the unit off and unplug the power cord from the

2. Remove all air hoses, accessories, and air tools from

the air compressor.

3. Perform the daily maintenance schedule.

4. Open the drain valve to bleed all air from the tank.

5. Close the drain valve.
