GLOSSARY
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. 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.
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 the air compressor is undersized for the required
air demand. Maximum compressor pumping time per hour is 30 minutes.

GROUNDING INSTRUCTIONS
RISK OF ELECTRICAL SHOCK. In the event of a short
circuit, grounding reduces the risk of shock by providing
an escape wire for the electric current. This air compressor must be
properly grounded.
The portable air compressor is equipped with a cord
having a grounding wire with an appropriate
grounding plug (see illustrations). The plug must be
used with an outlet that has been installed and
grounded in accordance with all local codes and
ordinances.
1.
The cord set and plug with this unit contains a
grounding pin. This plug MUST be used with a
grounded outlet.

USE AN ADAPTER.
240 Volt U.S.A. Plug
When used outside of the United
States of America a conversion kit may be required for
local use.
3. Inspect the plug and cord before each use. Do not use if there are signs
of damage.
4.
If these grounding instructions are not completely understood, or if in
doubt as to whether the compressor is properly grounded, have the
installation checked by a qualified electrician.
IMPROPER GROUNDING CAN RESULT IN ELECTRICAL
SHOCK.
Do not modify the plug provided. If it does not fit the available outlet, a
correct outlet should be installed by a qualified electrician.
Repairs to the cord set or plug MUST be made by a qualified electrician.
Extension Cords
Using extension cords is not recommended. The use of extension cords will
cause voltage to drop resulting in power loss to the motor and overheating.
Instead of using an extension cord, increase the working reach of the air hose
by attaching another length of hose to its end. Attach additional lengths of
hose as needed.
If an extension cord must be used, be sure it is:
• a 3-wire extension cord that has a 3-blade grounding plug, and a 3-slot
receptacle that will accept the plug on the product
• in good condition
• no longer than 50 feet
• 14 gauge (AWG) or larger. (Wire size increases as gauge number
decreases. 12 AWG, 10 AWG, and 8 AWG may also be used. DO NOT
USE 16 OR 18 AWG.)
Voltage and Circuit Protection
Refer to the Parts Manual for the voltage and minimum branch circuit
requirements.
Certain air compressors can be operated on a 15 amp circuit if the following
conditions are met.
1.
Voltage supply through branch circuit is 15 amps.
2.
Circuit is not used to supply any other electrical needs (lights, appliances,
etc.).
3.
Extension cords comply with specifications.
4.
Circuit is equipped with a 15 amp circuit breaker or 15 amp time delay
fuse. NOTE: If compressor is connected to a circuit protected by fuses,
use only time delay fuses marked “D” for Canada and "T" for US.
If any of the above conditions cannot be met, or if operation of the compressor
repeatedly causes interruption of the power, it may be necessary to operate it
from a 20 amp circuit. It is not necessary to change the cord set.
