Installation & Assembly
A WARNING
The air compressor should be turned off, unplugged from
the power source, the air bled from the tank and the unit
allowed time to cool before any maintenance is performed.
Personal injuries could occur from moving parts, electrical
sources, compressed air or hot surfaces. The quick
connect assembly must be attached before use. Failure
to assemble correctly could result in leaks and possible
injury. If unsure of assembly instructions or you experience
difficulty in the assembly please call our toll free number
for assistance.
Assembly
1. Remove air compressor, manual, air filter assembly,
and accessories from packaging.
2. Remove the plastic plug from the compressor intake
port, (see diagram beiow)
3. Install the filter in the compressor intake port.
(see diagram below)
Remove the oil fill cap from the crankcase and fill until
the oil reaches the top of the red dot in the sight glass.
Oil capacity is 3 oz. (see below) Use SAE-30
non-detergent (API CG/CD heavy duty motor oil).
Under extreme cold weather conditions use SAE-10
weight oil.
Replace the oil cap.

Getting Started - Location of the Air Compressor
The air compressor should always be located in a clean,
dry and well ventilated environment. The unit should have
at minimum, 12 inches of space on each side. The air filter
intake should be free of any debris or obstructions.
Check the air filter on a daily basis to make sure it is
clean and in working order.
The plug must be plugged into an outlet that is properly
installed and grounded in accordance with all local codes
and ordinances. Check with a qualified electrician or
service personnel if these instructions are not completely
understood or if in doubt as to whether the tool is properly
grounded.
A WARNING
Improper installation of the grounding plug will result in
a risk of electric shock. If repair or replacement of the
cord or plug is necessary, do not connect the grounding
wire to either flat blade terminal. The wire with insulation
having an outer surface that is green with or without
yellow stripes is the grounding wire. Check with a qualified
electrician or serviceman if the grounding instructions are
not completely understood, or if in doubt as to whether
the product is properly grounded. Do not modify the plug
provided, if it will not fit the outlet, have the proper outlet
installed by a qualified electrician.
This product is for use on a circuit having a nominal rating
of 120 volts and is factory-equipped with a specific electric
cord and plug to permit connection to a proper electric
circuit. Make sure the product is connected to an outlet
having the same configuration as the plug. An adapter
should not be used with this product. If the product must
be reconnected for use on a different type of electric
circuit, qualified service personnel should make the
reconnection.
Extension Cords
Use only 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. Make sure your extension cord is in
good condition. When using an extension cord, be sure to
use one heavy enough to carry the current your product
will draw. Cords must not exceed 25 feet and No. 12 AWG
size must be used. An undersized cord will cause a drop
in line voltage resulting in loss of power and overheating.
Grounding Instructions
This product should be grounded. In the event of an
electrical short circuit, grounding reduces the risk of
electric shock
by providing an escape wire for the electric current. This
product is equipped with a cord having a grounding wire
with an appropriate grounding plug. (See the figure below.)
