safety precautions must be
observed to avoid injuries and
damage. Please read the complete
operating manual with due care.
Keep this manual in a safe place,
so that the information
is available at all times. If you
give the equipment to any other

CAUTION:
FOR YOUR OWN SAFETY,
READ INSTRUCTION
MANUAL COMPLETELY AND
CAREFULLY BEFORE
OPERATING THIS GAS
COMPRESSOR.
Any failures made in
following the safety
regulations and instructions
may result in an electric
shock, fire and/or serious
injury.
SAFETY INSTRUCTIONS
1) Only persons who are
familiar with these
instructions and warnings
should operate this
compressor.
2) Do not allow children in the
work area and keep visitors
back away from equipment.
3) Use safety glasses and
hearing protection when you
are operating this unit.
4) Do not stand on the unit or
use it as a handhold.
5) Before each use, inspect
the compressor for signs of
damage, deterioration,
weakness or leakage. Repair
or replace damaged items
before use.
6) Check the fasteners at
frequent intervals to ensure
proper tightness.
7) Motors, electrical
equipment and their

controls can cause electrical
arcs that could ignite flammable
gas or vapors. Do not store any
flammable liquids or gases near
the compressor.
8) Carbon monoxide is
produced when operating this
unit and can cause severe
nausea, fainting or death. Do
not operate this unit in a poorly
ventilated area or while inside a
closed building.
9) Never operate a compressor
without a belt guard. It is
possible for a compressor to
start without warning. Personal
injury or property damage could
occur from coming in contact
with moving parts.
10) Do not wear loose clothing
or jewelry. Keep long hair pulled
back.
11) Compressor parts may be
hot even though the unit may be
stopped.
12) Keep fingers and
appendages away from the
compressor while it is running.
Fast moving and hot parts can
cause injury and/or burns.
13) If any of the equipment
starts to vibrate abnormally,
stop the engine/motor and
inspect the unit immediately for
the cause.
20) Make sure to drain the tank
regularly and inspect it
periodically for unsafe conditions
such as rust and corrosion.
21) Release air slowly when
draining moisture or
depressurizing the air
compressor system. Fast moving
air will stir up dust and debris,
which may be harmful.
22) Stop the engine and make
sure all moving parts have
stopped when leaving the work
area, before cleaning, making
repairs or inspecting the unit.
23) Allow the engine to cool
before storing the unit.
24) Do not spray flammable
materials within the vicinity of an
open flame or near ignition
sources, including the
compressor unit.
25) Do not smoke when spraying
paint, insecticides or other
flammable substances.
26) Use a facemask when
spraying. Spray in a well
ventilated area to prevent health
and fire hazards.
27) Do not direct any sprayed
materials at the compressor.
Keep the compressor as far
away as possible from the
spraying area to minimize the
accumulation on the compressor.
14) Never refuel a running or
hot engine. Fuel is explosive
and can cause fires and severe
burns. Avoid overfilling the fuel
tank.
15) Check the fuel level before
starting the engine. Do not fill
the gas tank while indoors.
Wipe off any spilled gas from
the unit before starting the
engine.
16) Gasoline vapors are highly
flammable. Only refill the tank
outdoors or in a well-ventilated
area. Do not store, use or allow
spills near an open flame or
heat devices that utilize a pilot
light or could create a spark. If
gasoline is spilt, move the unit
away from the spill and avoid
creating any sparks until the
vapors have evaporated.
17) In order to reduce the fire
hazard, keep the engine and
motor exterior free of oil,
solvents or excessive grease.
18) Never remove or attempt to
adjust the safety valve. Keep
the safety valve free from paint
and other accumulations.
19) Never attempt to repair or
modify a tank. Welding, drilling
or any other modifications made
will weaken the tank and result
in damage by rupture or
explosion. Always replace worn
or damaged tanks.

OPERATION
Start Up
1) Add 87 octane (or higher)
unleaded gasoline to the engine
gas tank and SAE 10W-30 oil to
the engine oil tank. A different
viscosity oil may be required if
the compressor is operated at
different ambient temperatures.
Please refer to the engine
manual for more details.
2) Remove the compressor
dipstick breather and fill the
pump to the proper oil level.
Use a single viscosity, ISO 100
(SAE 30) non-detergent
compressor oil. Do not use a
multi viscosity oil such as 10W-
30.
3) Turn the outlet valve or
regulator knob counterclockwise
to open the airflow.
4) Turn the manual unloader
lever to a vertical position in
order to allow the compressor
pump to run without
compressing air.
Starting A Gasoline Engine
1) Move the choke lever to the
CHOKE position and turn the
stop lever towards the ON
position.
2) Pull the start grip lightly until
resistance is felt, then pull on the
start grip briskly to start the
engine.
3) As the engine begins to warm
up, gradually move the choke
lever to the OPEN position.
4) Run the compressor at an
unloaded speed for
approximately 30 minutes in
order to break in the pump.
5) After approximately 30
minutes of run time, move the
unloader lever down to the
loaded position and turn the
regulator knob clockwise. The
compressor will begin to pump
air into the tank at this time.
When the maximum tank
pressure is achieved, the
compressor automatically
unloads, which brings the
engine to idle. The engine
remains at the idle state until the
pressure in the tank falls to a
preset level. The engine will then
accelerate and the compressor
will pump additional air into the
tank.
MAINTENANCE
WARNING: Release all
pressure from the system
before attempting to perform
any maintenance, relocate,
service or install the unit.
Check the air filter, oil level and
gasoline level before each use in
order to maintain efficient
operation of the unit.
The ASME safety valve should
be checked before each use. Pull
the ring on the safety valve and
allow the ring to snap back into
its normal position. This valve
automatically releases air if the
tank pressure exceeds a preset
maximum. If air leaks after the
ring has been released, or if the
valve is stuck and cannot be
actuated by the ring, the ASME
safety valve must be replaced.
Do not attempt to tamper with
the ASME safety valve.
With the engine OFF, clean any
debris from the engine, flywheel,
tank, air lines and pump cooling
fins.
Never attempt to repair or
Page 4

modify the tank. Welding,
drilling or any other
modifications will weaken the
tank and could result in
damage from rupture or
explosion. Always replace
worn, cracked or damaged
tanks as soon as possible.
Drain liquid from the tank at
the end of each use.
Drive Belt
Belts will stretch as a result of
normal use. When they are
properly adjusted, the belt
deflects about ½ inch with 5
pounds of pressure applied
midway between the engine
pulley and pump.
To adjust the drive belt tension:
1) Remove the belt guard and
loosen the engine brace.
2) Loosen the four fasteners
that are holding the motor to the
base plate.
3) Shift the motor in the proper
direction. The belt must be
properly aligned when this
adjustment is made.
4) To align the belt, lay a
straight edge against the face of
the flywheel, touching the rim at
two places.
5) Adjust the flywheel or motor
pulley so that the belt runs
parallel to the straight edge.
6) Use a gear puller to move the
pulley on the shaft and to tighten
the fasteners.
7) Adjust the brace and then
tighten the fasteners, braces and
reinstall the belt guard.
Storage
1) When the unit is not in use,
the air hose and compressor
should be stored in a cool, dry
location.
2) Tanks should be drained of
moisture. The hose should be
disconnected and hung with the
open ends down to allow any
moisture to drain.
