6. DO NOT USE A GENERATOR AS THE POWER SOURCE
Air compressors use inductive motors that require 3-5 times the full-load amp draw to properly start. Most generators will not
provide the wattage needed to properly start this type of electric motor.
7. CHECK TENSION OF BOLTS AND HARDWARE ON A REGULAR BASIS
Operation of any equipment with loose bolts and/or fittings will lead to excessive vibration
and the premature failure of the compressor system control components.
8. MAINTAIN RUBBER VIBRATION PADS
Excessive vibration is a major cause of premature compressor failure. Always maintain the rubber vibration pads located
beneath tank assembly. Operation without them will void your warranty.
9. DRAIN MOISTURE FROM AIR TANKS DAILY
Water is a natural byproduct of compressed air. Drain air tank(s) after each use to combat internal tank corrosion. Keep drain
valve(s) closed if storing compressor for any length of time.

WARNING
Your safety and the wellbeing of others during the operation of every
not operate or permit anyone else to operate your air compressor until the information contained in this manual is read and
completely understood. Please contact your distributor or our customer service department if you have any questions on the proper
use of your air compressor.
WET CONDITIONS: Do not operate your compressor in damp or wet conditions, or after it has been exposed to rain/sleet/ice/snow
or moisture of any kind. Failure to follow this warning could lead to electric shock and/or rust and ice forming on critical
components, making the compressor dangerous to operate. Always operate and/or store compressor in a clean, dry location with
good ventilation.
DIRECT-DRIVE ELECTRIC
Establish that the air compressor is ready to operate by reviewing the topics and information provided in the "Pre-Start
Checklist" section of this manual. Slowly open tank drain to remove any condensate that has accumulated and keep drain open for
a few seconds after starting to warm up motor/pump assembly. Make sure the pressure switch lever is in the "Off" position before
plugging power cord into a properly grounded outlet. Move pressure switch lever to the "On/Auto" position to build and
automatically maintain top end tank pressure setting. Rotate regulator adjustment knob counterclockwise until the gauge attached
reads 0 PSI before attaching air hose and accessory. Set working pressure by rotating regulator adjustment knob clockwise and lock
in working pressure according to specifications provided by the tool manufacturer. Always use the pressure switch "On(Auto)/Off"
lever to start or stop the air compressor. Never stop the compressor by unplugging it from the power source. Store compressor in a
warm/dry location and perform maintenance as indicated in manual.
