5.
Shift the motor back to the point where the correct deflection exists
(see "Drive Belt Tension Adjustment").
6.
Retighten the motor mounting bolts to 130-180 in.-lbs.
7.
Check to ensure that the tension remained correct.
8.
Reinstall the belt guard. All moving parts must be guarded.
TO REPLACE OR CLEAN CHECK VALVE
WARNING:
automatically. ALWAYS shut off the compressor, remove
the plug from the outlet, and bleed all pressure from the
system before servicing the compressor, and when the
compressor is not in use. Do not use the unit with the
shrouds or belt guard removed. Serious injury could occur
from contact with moving parts.
1.
Turn air compressor off,
remove the power cord from
the outlet or lock out the
power supply and relieve all
the air pressure from the tank
(refer to "Shutdown" in
Operating Instructions).
Make sure the compressor has
cooled down before servicing.
2.
Using the appropriately sized
wrench, loosen the compression
nut (A) on the check valve (B).
Gently move the transfer tube
(C) out of the way.
3.
Remove the bleeder tube (D)
from the elbow (E ) located on
the side of the check valve by
gently pulling it off the barbed end.
4.
Making note of the orientation for reassembly,
unscrew the check valve from the tank
(counterclockwise) using a 7/8" open end
wrench.
5.
Using a pencil or screwdriver, carefully push the
valve disc up and down. If the valve disc does
not move freely up and down, the check valve
needs to be cleaned or replaced.
6.
Clean the check valve with warm soapy water
and make sure to dry thoroughly before
reinstalling. If the disc valve still does not move
freely up and down, it will need to be replaced.
Perform the following maintenance at the intervals indicated below.
Inspect air filters (clean or replace as necessary)
Check pump oil level
Change pump oil (Use full synthetic, non-detergent air compressor oil.)
Operate the tank safety valve
Check belt tension
Drain tank
Check and tighten all bolts (do not over tighten)

7.
Apply thread sealant to the check valve threads and reinstall into the
tank by turning clockwise. Make sure it is the same orientation as
when it was removed.
8.
Replace the bleeder tube by pushing it back onto the barbed fitting of
the elbow.
9.
Replace the transfer tube and tighten compression nut.
CLEANING THE AIR FILTERS
A dirty air filter will
reduce the compressor's
performance and life. To
avoid any internal
contamination of the
pump, the filters should be
cleaned frequently, and
replaced on a regular
basis. Felt filters should be
cleaned in warm, soapy
water, rinsed, and allowed
to air dry before reinstallation. Paper filters should be replaced when dirty.
Do not allow the filters to become filled with dirt or paint. If the filter
becomes filled with paint, it should be replaced. Direct exposure to dirty
conditions or painting areas will void your warranty.
A
CHECKING THE RELIEF VALVE
B
E
Pull the tank safety valve daily to ensure that it is operating properly
and to clear the valve of any possible obstructions.
TESTING FOR LEAKS
Check that all connections are tight. A small leak in any of the
hoses, transfer tubes, or pipe connections will substantially reduce the
performance of your air compressor. If you suspect a leak, spray a small
amount of soapy water around the area of the suspected leak with a spray
bottle. If bubbles appear, repair or replace the faulty component. Do not
over tighten any connections.
STORAGE
Before storing the compressor for a prolonged period, use an air
blow gun to clean all dust and debris from the compressor. Disconnect the
power cord and coil it up. Pull the tank safety valve to release all pressure
from the tank. Drain all moisture from the tank. Clean the filter elements
and filter housings; replace the elements if necessary. Drain the oil from
the pump crankcase and replace it with new oil. Cover the entire unit to
protect it from moisture and dust.
