Installation & Assembly
A WARNING
The air compressor should be turned off and unplugged from
the power source before any maintenance is performed as
well as the air bled from the tank and the unit allowed time
to cool. Personal injuries could occur from moving parts,
electrical sources, compressed air or hot surfaces. The
regulator 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 your local service department for
further instruction.
Quick Connect Assembly
1. Before assembly be sure that the
Quick Connect (Q.C.) threads have a
sealant applied from the factory to prevent
leaks around the threads. If no sealant is
present, wrap the threaded portion with
Teflon tape.
2. Attach the Q.C. assembly to the air compressor by
aligning the Q.C. threads to the regulator on the manifold.
Be certain to align the threads before tightening to prevent
thread damage.
3. The assembly should turn clockwise 1 to 1.5 revolutions
after hand-tightening with a 13/16ths size wrench. To prevent
damage and leaks, do not
over-tighten.
To Install the Air Intake Filter
Remove the air intake filter from the
poly bag and thread it onto the head
of the compressor as shown.
A CAUTION
Do not attempt to start the air compressor without first adding
oil to the crankcase. Serious damage can result unless filled
with oil. The pump is shipped without oil from the factory.
Only use non-detergent oils since multi-viscosity motor oils
leave carbon deposits on pump components, thus reducing
performance and compressor life.
A WARNING
Drain the tank to release all tank air
pressure before removing the oil fill cap.
Be sure the air vent in the oil fill cap {see
figure to the right) is free from debris.
If air vent is blocked, pressure can build
in crankcase causing damage to the
compressor and possible personal injury.
Lubrication and Oil
Remove the oil fill cap by turning it
counter-clockwise by hand. Fill the
compressor pump with an air compressor
oil such as SAE-30 non-detergent (API
CG/CD Heavy Duty) oil at slow intervals
until the oil reaches the center of the red
circle in the sight glass ( see figure above).
Use SAE-10 during extreme winter conditions.
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 fitter
intake should be free of any debris or obstructions. Check
the air filter on a daily basts to be sure it is clean and in
working order.
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.) 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 oonnect 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
property 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 that the product is connected to an outlet having
the same configuration as the plug. No adapter should 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.
Break In Procedures
No break in procedure is required by the user. This
product is factory tested to ensure proper operation and
performance.
