ASME Safety Valve
A safety valve that automatically releases
the air if the air receiver (tank) pressure
exceeds the preset maximum.
PSI (Pounds per Square Inch)
Measurement of the pressure exerted by
the force of the air. The actual psi output
is measured by a pressure gauge on the
compressor.
ACFM (Actual Cubic Feet per Minute)
Sometimes called CFM (Cubic Feet per
Minute). Measurement of air volume
delivered by the compressor at a given
pressure..
Air Delivery
A combination of psi and SCFM. The air
delivery required by a tool is stated as
(number) SCFM at (Number) psi. The
combination of these figures determines
what size compressor is needed.

WARNING
Glossary of Terms
Regulator (Not Included)
A control that adjusts the line pressure to
the proper amount needed to operate
spray guns and air tools.
Tank Pressure Gauge
Indicates tank pressure in psi.
Unpacking and Checking Contents
1. Remove the air compressor from the
carton.
2. Place the compressor on a secure,
stationary work surface and look it
over carefully.
Do not operate unit if damaged
during shipping, handling or use.
Damage may result in bursting
and cause injury or property damage.
!
WARNING
To reduce the risk of injury, if any
parts are missing, do not attempt to
assemble the air compressor until
the missing parts are obtained and
installed correctly.
!
WARNING
For your own safety, never operate
unit until all assembly steps are
complete and until you have read
and understood the entire operator’s
manual.

Troubleshooting
TROUBLE
REMEDY
PROBABLE CAUSE
Overheating
1. Relocate the compressor
to an area where an ample
supply of cool, clean, dry
and well-circulated air is
available
2. Clean the cooling surfaces
of pump and engine.
3. Check air requirements of
tools
1. Poor ventilation
2. Dirty cooling surfaces
3. Compressor undersized for
application
1. Increase idle, refer to
engine manual for details
2. Check for proper oil level
3. Replace
1. Low engine idle
2. Improper lubrication
3. Defective pilot/unloader valve
Unit stalls
Excessive noise
1. Loose pulleys are a com-
mon cause of “knocking”.
Tighten appropriate bolts
2. Check for proper oil level
3. Replace
4. Remove piston assembly
and replace necessary
parts
5. Replace bearings and oil
6. Check for proper belt
tension
1. Loose drive pulley or flywheel
2. Lack of oil in crankcase
3. Worn connecting rod
4. Worn wrist pin bushing
5. Worn bearings
6. Loose belts
Oil in the discharge
air
1. Change oil. Check oil
recommendations on page
7 of this manual
2. See above section
3. Clean or replace air filter
4. Replace
1. Wrong type or inferior grade
of oil
2. Overheating
3. Restricted intake air
4. Worn piston rings
