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, replace it with a new filter,The filter may be removed by using a pair of
needle nosed pliers or a screwdriver, Pull or pry out the old filter, Push in the new
air filter,
Oil - Checking and Changing
Drain tank to release air pressure before removing the oil
fill cap or oil drain plug
I_ Overfilling with oil will cause premature compressor
failure. Do not overfill,
Check oil level in the crankcase daily. Remove the oil fill D_UO. The oil level should be
even with the too of the fill hole and must not be allowed to be lower than 3/8" from
the ted (6 threads_at aqy tim_. It is recommended that the oil be changed after every
100 hours of operation. To drain the oil, remove the oil drain plug and collect the oil
in a suitable container.Be sure to replace the plug securely before adding new oil.
Use a air compressor oil such as SAE-20 (API CG/CD heavy duty). Under extreme
winter conditions use SAE-10 weight oil. Crankcase oil capacity is approximately 16
fluid ounces (473.2 ml).
Check Valve - Inspection and Replacement
Remove and inspect the check valve at least once a year or more often if the
compressor is heavily used. Moisture and other contaminants in the hot
compressed air will cause an accumulation of a carbon-like residue on the working
parts. If the valve has heavy carbon build-up, it should be replaced. Use the
following procedure to inspect, clean or replace the check valve.
1. Unplug compressor. Release air pressure from the air tank.
2. Loosen the top and bottom tube nuts and remove the outlet tube.
3. Unscrew the check valve using socket wrench (7/8").
4. Check that the valve disc moves freely and that the spring holds the disc in the
upper, closed position. The check valve may be cleaned with a solvent.
5. Apply sealant to the check valve threads. Reinstall the check valve. Do not
overtighten.
6. Replace the outlet tube and tighten top and bottom tube nuts.
Safety Valve - Inspection and Replacement
IF THE SAFETY VALVE DOES NOT WORK PROPERLY,
OVER-PRESSURIZATION MAY OCCUR CAUSING AIR TANK RUPTURE
OR 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 A VALVE HAVING THE SAME PRESSURE RATING.
Belt - Replacement
SERIOUS INJURY OR DAMAGE MAY OCCUR IF PARTS OF
THE BODY OR LOOSE ITEMS GET CAUGHT IN MOVING PARTS.
NEVER OPERATE THE UNIT WITH THE BELT GUARD REMOVED. THE
BELT GUARD SHOULD BE REMOVED ONLY WHEN THE
COMPRESSOR IS UNPLUGGED.
