DUTY CYCLE
Air compressors should be operated
on not more than a 50% duty cycle.
This means an air compressor that
pumps air more than 50% of one
hour is considered misuse, because
ACCESSORIES
Become familiar with these terms
before operating the unit.
CFM: Cubic feet per minute.
SCFM: Standard cubic feet per
minute; a unit of measure of air
delivery.
PSIG: Pounds per square inch
gauge; a unit of measure of pressure.
Code Certification: Products that
bear one or more of the following
marks: UL, CUL, ETL, CETL, have
been evaluated by OSHA certified
independent safety laboratories and
meet the applicable Underwriters
Laboratories Standards for Safety.
Cut-In Pressure: While the motor is
off, air tank pressure drops as you
continue to use your accessory.
Accessories
• In Line Filter
• Tire Air Chuck
• Quick Connector Sets
(various sizes)
Refer to the selection chart located
on the unit to select the tools this unit
is capable of powering.
The accessories and tools are
available through the current Power
and Hand Tool Catalog or full-line
Sears stores.
When the tank pressure drops to a
certain low level the motor will restart
automatically. The low pressure at
which the motor automatically
restarts is called “cut-in” pressure.
Cut-Out Pressure: When an air
compressor is turned on and begins
to run, air pressure in the air tank
begins to build. It builds to a certain
high pressure before the motor
automatically shuts off - protecting
your air tank from pressure higher
than its capacity. The high pressure
at which the motor shuts off is called
“cut-out” pressure.
Branch Circuit: Circuit carrying
electricity from electrical panel to
outlet.
• Air Pressure Regulators
• Oil Fog Lubricators
• Air Hose:
1/4", 3/8" OR 1/2" I.D.
in various lengths
the air compressor is undersized for
the required air demand. Maximum
compressor pumping time per hour is
30 minutes.
