5. USE LONGER, PROPERLY SIZED AIR HOSE RATHER THAN EXTENSION CORDS
If an extension cord must be used, please refer to the chart below for the proper gauge and maximum length that can be used.
The use of inadequately sized air hose will also lead to frictional pressure drops that could affect the proper performance of
your air tools.
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.
