SERVICE INSTRUCTIONS
Air Filter - Inspection and Replacement
Keep the air filter clean at all times. Do not operate the compressor with the air
filter removed. A dirty air filter will not allow the compressor to operate at full
capacity. Before you use the compressor, check the air filter to be sure it is clean. If
it is dirty wash it with mild detergent and warm water, or replace it.
Safety Valve - Inspection
IF THE SAFETY VALVE DOES NOT WORK PROPERLY,
OVER-PRESSURIZATION MAY OCCUR, CAUSING AIR TANK
RUPTURE OR AN EXPLOSION. DAILY PULL THE RING ON THE
SAFETY VALVE TO MAKE SURE THAT THE SAFETY VALVE OPERATES
FREELY. IF THE VALVE IS STUCK OR DOES NOT OPERATE
SMOOTHLY, IT MUST BE REPLACED WITH THE SAME TYPE OF
VALVE.
Check Valve Replacement
1. Release all air pressure from air tank and unplug outfit.
2. Remove shroud.
3. Loosen the top and bottom nuts and remove the outlet tube.
4. Remove the pressure release tube and fitting.
5. Unscrew the check valve using a socket wrench.
MAINTENANCE
Unit cycles automatically when power is on. During
maintenance, you could be exposed to voltage sources, compressed
air, moving parts, or hot surfaces. Personal injuries can occur. Unplug
the unit and bleed off all air tank pressure and allow unit to cool
before doing any maintenance or repair. Never operate the unit with
the belt guard removed.
To ensure efficient operation and longer life of the air compressor outfit, a routine
maintenance schedule should be prepared and followed. The following routine
maintenance schedule is geared to an outfit in a normal working environment
operating on a daily basis. If necessary, the schedule should be modified to suit the
conditions under which your compressor is used. The modifications will depend
upon the hours of operation and the working environment. Compressor outfits in an
extremely dirty and/or hostile environment will require a greater frequency of all
maintenance checks.
ROUTINE MAINTENANCE SCHEDULE
Daily:
1. Pull ring on safety valve allowing air to bleed from the tank until tank pressure is
approximately 20 psi. Release safety valve ring.
2. Drain water from the air tank, any moisture separators, or transformers.
3. Check for any unusual noise and/or vibration.
4. Manually check safety valve to make sure of proper operation.
5. Inspect air filter and replace if necessary.
6. Inspect air lines and fittings for leaks and correct as necessary.
Each Year of Operation or if a Problem is Suspected:
Check condition of air compressor pump intake and exhaust valves. Replace if
damaged or worn out.
