UNPACKING
Inspect your air compressor carefully for any damage that may have occurred during transit. Be sure to inspect and
tighten all bolts, screws and fittings before attempting to start the unit. Do not attempt to operate a damaged unit. It
may burst and cause serious injury or property damaged.
Your compressor comes equipped with a guard over the drive wheel and belt assembly.
Never attempt to operate this unit if the guard is damaged or removed. Personal injury
could result from contact with moving parts.
Never remove or attempt to adjust the safety valve. Keep it free from paint or any other
accumulations.
This unit may cause electrical arcs that could ignite flammable gas or vapor. Keep
flammable items away from the compressor and keep the compressor from flammable
conditions.
Compressor parts may be hot even if the unit is not running.

HOSE AND REGULATOR Use 3/8 inch hose and regulator that has a minimum rating that exceeds the maximum
working pressure of the compressor. The amount of air pressure released at the hose outlet is controlled by the
regulator.
ACM SAFETY VALVE This valve will release excessive pressure if the maximum pressure is exceeded.
DISCHARGE TUBE This tube carries compressed air from the pump to the check valve. Never touch the
discharge tube because it becomes very hot during operation.
UNLOADER Valve used to release all pressure from the tanks and pump for starting.
CHECK VALVE This is a one way valve that allows air to enter the tank but prevent air from going out of the
tank.
HANDLE The handle is provided to move the compressor.
BELT GUARD The belt guard covers the belt and pulley.
DRAIN PETCOCK Each tank has a drain petcock on the bottom and is used to drain moisture from the tank.
Open the petcock and reduce air pressure below 10 psi and allow moisture to drain. This should only be done daily
to reduce the risk of corrosion.
START UP
UNDERSTANDING YOUR UNIT
Starting the unit with electric start
Unit is shipped with the battery cables
disconnected.
oAttach positive (red) lead first.
oAttach negative (black) lead last.
Rotate the fuel valve to the “on”
position.(figure 1 or 2)
Move the choke to the “closed” or “start”
position. (figure 2 or 6 depending on the type
of engine. Consult your engine manual)
Open the unloader as shown in figure 8.
oNote, it is normal for air to
escape when the unloader is
opened for starting. Pressure
must be released from the
system prior to starting the
engine.
Assure the throttle is pushed to the left.
(figure 5)
Turn key to the “start” position. See figure 6
Once engine starts, return key to the “run”
position.
Move choke to the “open” or run position.
Close the unloader valve as shown in figure 7
.
Starting the unit manually
Rotate the fuel valve to the “on” position.(figure 1
or 2)
Move the choke to the “closed” or “start” position.
(figure 2 or 6 depending on the type of engine.
Consult your engine manual)
Open the unloader as shown in figure 8.
oNote, it is normal for air to escape
when the unloader is opened for
starting. Pressure must be
released from the system prior to
starting the engine.
Assure the throttle is pushed to the left. (figure
5)
Turn key to the “on” position. See figure 4 or
rotate ignition switch to the right as shown in
figure 3.
Pull starter grip slowly until resistance is felt.
Pull cord briskly
Return starter cord gently into the recoil housing.
Move choke to the “open” or run position.
Close the unloader valve as shown in figure 7

Stored batteries give off explosive hydrogen gas while
recharging. An explosive mixture will remain around
the battery for a period of time after it has completed
recharging. Any spark can ignite the hydrogen and
cause an explosion. Such an explosion can shatter
the battery and cause blindness or other serious
injury.
Avoid smoking, open flames, sparks or any other
source of heat around a battery. Wear protective
goggles, rubber apron and rubber gloves when working
around a battery. Battery electrolyte fluids are an
extremely corrosive sulfuric acid solution than can
cause severe burns. If a spill occurs, immediately flush
with clear water.
Never short the battery terminals!
Electrical short, shock, burns or
explosion will occur!
Stopping the engine
Rotate key or ignition switch
counterclockwise to the off position.
Rotate the fuel valve to the closed position
for storage, maintenance or transportation.
Disconnect battery for storage or
maintenance.

6. CLOSE OIL CAP.
7. Change oil as published
1. Remove cover panel.
2. Loosen screw and remove air
filter cover
3. Never wash air cleaner with any
kind of detergent or cleaning sol-
vent.
4. Air filter should be changed if
engine performance decreases or
color of exhaust changes.
5. Never run engine without air filter.
This will cause rapid engine wear.
1. Fill with gasoline fuel only
2. Clean area around fuel cap.
3. Remove fuel cap.
4. Add fuel to fuel tank.
5. DO NOT overfill. Do not fill above
the red plug inside the fuel tank
filter (this allows for fuel expansion)
6. Replace fuel cap.
7. Wipe up any spilled fuel.
CHANGING THE ENGINE OIL
*First oil change should be after 5 hours. After initial break-in period change oil every (30) hours.
Remove the oil cap or dipstick
Place a container underneath the drain bolt
Unscrew the oil drainage bolt
Allow oil to drain completely
Reinstall the drainage bolt and tighten securely.
Refill the oil per the check and fill instructions above.
16 ounce oil capacity in the crankcase depending on the amount of oil drained.
Reinstall the dipstick.
NOTE: Used oil must be disposed of properly. Take used motor oil to an approved recycling center.
*First oil change should be after 5 hours. After initial break-in period change oil every (30) hours.
SPARK PLUG MAINTENANCE
The spark plug must be properly gapped and free of deposits in order to ensure proper engine operation.
Remove the spark plug cap
Clean area around the base
Remove the spark plug
Inspect the spark plug for damage and clean with a wire brush. If there is any damage, the plug should be replaced. If you
replace the plug, use the recommended spark plug or equivalent: NGK-BPR6ES.
The gap between the electrodes is .027’-.030”SEE ENGINE MANUAL.
Thread the spark plug in by hand to prevent cross threading.
If using a NEW plug, once the plug seats by hand, tighten the plug 1/2 rotation with a wrench to compress the washer.
If reusing the old plug, once the plug seats by hand tighten the plug 1/8-1/4 rotation with a wrench to compress the washer.

COMPRESSOR PUMP
Problem
Cause
Solution
Low Discharge Pressure
1.) Air leaks
2.) Leaking valves
3.) Restricted air intake
4.) Slipping belt
5.) Blown head or seals in
pump
6.) Regulator/unloader valve
needs adjusting
7.) Low compression
1.) Listen for escaping air. Apply
soap solution to fittings to see
if the bubbles appear
2.) Replace ACM or
