Installation & Assembly
A WARNING
Ths air coTDpressor should bo turned oft and unplugged from the
power source before any maintenance is performed as well as
the air bled from the lank and iha unit allowed time
to cool. Personal Injunes could occur from moving parts, electri­
cal sources, compressed air or hot surfaces. The
regulator assembly must be attached before use. Failure to
assemble correctly could resuh In leaks and possible Injury
If unsure ol assembly instructions or you expedence difficulty in
the assembly please call your local service department lor further
Instructioti.
Quick Connect Assembly
1.
Before assembly be sure that the
Quick Connea (Q C.) threads have a
sealant applied from the factory to prevent
leaks around the threads. If no seaiarrt is
present, vurap the threaded portion vvHh
Teflon taps.
2
Remove the regulator's plastic plug. Attach
the O 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. After hand tightening, the assembly should be turned clock
wise 1 to 1.5 revolutions with a I3^6ihe size wrench.
To prevent damage and leaks, do nor over-tighten
To Install the Air Intake Rltsr
Remove the plastic plug from the
compressor head. Remove the air intake
filler from the poly bag and thread it onto the
head of the compressor as shown.
A CAUTION
Do not attempt to star the air compressor
without first adding oil to the crankcase Serious damage can
result unless fffied with oil The pump Is shipped without oil from
the factory. Only use non-dstergent oils since multf-vlscostiy
motor oils leave carbon deposits on pURip eomponems, thus
redudng
petfetTnanee and compressor life.
A WARNING
Drain the tank to release all tank air
pressure before removing the oD flit cap. Be sure the air vant in
the oU fill cap (see figure lo the right) is free \
from debris, if air vent Is blocked, pressure \
can buttd 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
rton-detergent (API CG/CD Heavy Duty) oU
at slow intervals undl the oil reaches the
center of the red circle In the sight glass
( see figure above). Use SAE-10 during
extreme winter conditions.

should be kee ol any debns or obstructiorrs. Check the air filter
on a dally basis to be sure it is dean and in working order
Grounding Inatructlons
This product should be grounded. In the event ol an elecirical
short circuit, grounding reduces the risk of electric eho^ by pro­
viding an escape wire for the eiectrlc cutrenL This product is
equipped with a cord having a grounding wire with an appropri­
ate groundng plug. (See the figure below) The plug must be
plugged into an outlet that Is properly Installed and grourtded h
acoordanoB whh an local codes and ordinances Check with a

A WARNING
Improper Installation of the grounding plug virlll result In a
nsk of electric ehock. IF repair or replacement of the cord
or plug Is neceseary, do not connect foe grounding wire to either
flat blade terminal. The wire with insulation having an outer sur­
face that Is green wfth or wlfoout yellow stripes Is the grounding
wire Cheek with a qualified electrician or serviceman if foe

doubt as to whether the product is properly grounded. Do not
modlty the plug provided, It It will not lit foe outlsL have the prop­
ar outlet installed by a qualified electrician.
This product Is for use on a tircuit having a nominal rating
oM30 volts and Is lactory-equlpped with aspecifie electric cord
and plug to permit connection to a proper electric circuit Make
sure that the product Is connected to an outlet havtng the same
configuration as the plug. No adapter should be used with this
product H the product must be reconnected for use on a diffen
ent type of etecirle circuit qualified service personnel should
make foe reconnection,

tion. Whan using an extension cord, be sure to use one heavy
enough to carry foe current your product will draw. Cords must
not exceed 25 feet and No. 12 AWG size must be used An
undersized cord wiR cause a drop In line voltage resulting In loss
ol power end overheating.
