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.
Regulator Assembly
1, Before assembly remove the shipping plug and label
from the manifold adapter. Check to be sure that the
adapter has a sealant applied from the factory to
prevent leaks around the threads.
2, Attach the regulator assembly to the air compressor by
aligning the regulator to the threaded male adapter on
the manifold. Be certain to align the threads before
tightening to prevent thread damage.
3, The assembly should turn clockwise for approximately
6-7 revolutions. The tank and regulator gauge should
be facing in the same direction (see the figure below}.
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
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 per­
sonal injury.
Lubrication and Oii
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 filter
intake should be free of any debris or obstructions. Check
the air filter on a daily basis 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 nroundinn nluo tfiee
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.
