– A POTENTIAL HAZARD THAT COULD CAUSE SERIOUS INJURY OR LOSS OF LIFE.
– A POTENTIAL HAZARD THAT MAY CAUSE MODERATE INJURY OR DAMAGE TO EQUIPMENT.
WARNING:
DANGER:
CAUTION:
1.
RISK OF FIRE OR EXPLOSION. Never spray
flammable liquids in a confined area. It is normal for
the motor and pressure switch to produce sparks
while operating. If sparks come into contact with
vapors from gasoline or other solvents, they may
ignite, causing fire or explosion. Always operate the
compressor in a well–ventilated area. Do not smoke 
while spraying. Do not spray where sparks or flame
are present. Keep compressor as far from spray area
as possible.
2.
RISK OF BURSTING. Do not weld, drill or modify the 
air tank of this compressor. Welding or modifications 
on the air compressor tank can severely impair tank 
strength  and cause an extremely hazardous 
condition. Welding or modifying the tank in any 
manner will void the warranty.
3.
RISK OF ELECTRICAL SHOCK. Never use an 
electric air compressor outdoors when it is raining or 
on a wet surface, as it may cause an electric shock.
4.
RISK OF INJURY. This unit starts 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 beltguard removed. Serious injury 
could occur from contact with moving parts.
5.
RISK OF BURSTING. Check the manufacturer’s 
maximum pressure rating for air tools and 
accessories. Compressor outlet pressure must be 
regulated so as to never exceed the maximum 
pressure rating of the tool. Relieve all pressure 
through the hose before attaching or removing 
accessories.
6.
RISK OF BURNS. High temperatures are generated 
by the pump and manifold. To prevent burns or other 
injuries, DO NOT  touch the pump, manifold or 
transfer tube while the pump is running. Allow them to
cool before handling or servicing. Keep children away 
from the compressor at all times.
7.
RISK TO BREATHING. Be certain to read all labels 
when you are spraying paints or toxic materials, and 
follow the safety instructions. Use a respirator mask if 
there is a chance of inhaling anything you are 
spraying. Read all instructions and be sure that your 
respirator mask will protect you. Never directly inhale 
the compressed air produced by a compressor. It is 
not suitable for breathing purposes.
8.
RISK OF EYE INJURY. Always wear ANSI Z87.1
approved safety goggles  when using an air
compressor. Never point any nozzle or sprayer
toward a person or any part of the body. Equipment 
can  cause serious injury if the spray penetrates the 
skin.
9.
RISK OF BURSTING. Do not adjust the relief valve
for any reason. Doing so voids all warranties. The
relief valve has been pre-set at the factory for the
maximum pressure of this unit. Personal injury and /or
property damage may result if the relief valve is 
tampered with.
10. RISK OF BURSTING.Do not use plastic or pvc pipe
for compressed air. Use only gavanized steel pipe
and fittings for compressed air distribution lines.
11. RISK TO HEARING. Always wear hearing protection
when using an air compressor. Failure to do so may
result in hearing loss.
12. The power cord on this product contains lead, a 
chemical known to the State of California to cause 
cancer, and birth defects or other reproductive harm. 
Wash hands after handling.
NOTE: ELECTRICAL WIRING. Refer to the air compressor’s 
serial label for the unit’s voltage and amperage 
requirements. Ensure that all wiring is done by a 
licensed electrician, in accordance with the National 
Electrical code.
WARNING
1.
Drain the moisture from the tank on a daily basis. A 
clean, dry tank will help prevent corrosion.
2.
Pull the pressure relief valve ring daily to ensure that 
the valve is functioning properly, and to clear the 
valve of any possible obstructions.
3.
To provide proper ventilation for cooling, the 
compressor must be kept a minimum of 12 inches (31 
cm) from the nearest wall, in a well–ventilated area.
4.
To prevent damage to tank and compressor on 
stationary models, the tank must be shimmed so the 
pump base is level within 1/8”  to distribute oil 
properly. All feet must be supported, shimming where 
necessary, prior to attaching to the floor. Fasten all 
feet to floor. We also recommend the use of vibration 
pads (094-0021) under tank feet.
5.
Fasten the compressor down securely if transporting 
is necessary. Pressure must be released from the 
tank before transporting. 
6.
Protect the air hose and electric cord from damage 
and puncture. Inspect them weekly  for weak or worn 
spots, and replace if  necessary.
7.
To reduce the risk of electric shock, do not expose to 
rain. Store indoors.
8.
Never operate the compressor if the power cord or 
plug are damaged. Take the equipment to the nearest 
Authorized Service Center , and a specialist technician
will replace it.
