Important Safety Instructions & Guidelines
Risk of Breathing
Avoid using the air compressor in confined areas. Always have adequate space
(12 inches) on all sides of the air compressor. Also keep children, pets, and others out of
the area of operation. This air compressor does not provide breathable air for anyone or
any auxiliary breathing device. Spraying material will always need to be in another area
away from the air compressor to not allow intake air to damage the air compressor filter.
Risk of
Electrical Shock
Never utilize the air compressor in the rain or wet conditions. Any electrical issues or
repairs should be performed by authorized personnel such as an electrician and should
comply with all national and local electrical codes. The air compressor should also have
the proper three prong grounding plug, correct voltage, and adequate fuse protection.
Risk of
Explosion or Fire
Never operate the compressor near combustible materials, gasoline or solvent vapors.
If spraying flammable materials, locate the air compressor at least 20 feet away from the
spray area. Never operate the air compressor indoors or in a confined area.
Risk of Bursting
Always drain the air compressor tank daily or after each use. If the tank develops a leak,
then replace the air compressor. Never use the air compressor after a leak has been
found or try to make any modifications to the tank. Never modify the air compressor’s
factory settings which control the tank pressure or any other function.

Cut-In Pressure:
The air compressor will automatically
start to refill the tank when the pressure drops
below the prescribed minimum.
Cut-Out Pressure:
The point at which the motor stops
when the tank has reached maximum air
pressure.
Code Certification:
Products that bear one or more of
the following marks: UL, ULc, ETL, CSA, have
been evaluated by CSHA-certified independent
safety laboratories and meet the applicable
Underwriters Laboratories Standards for Safety.
This is a 50% duty cycle air compressor. Do not run the air compressor more than 30 minutes of one hour. Doing so
could damage the air compressor.
