GENERAL OPERATING
INSTRUCTIONS
Read the ENTIRE IMPORTANT
SAFETY INFORMATION
section at the beginning of this
manual including all text under
subheadings therein before set up
or use of this product.
Compressor Area Set Up
Designate a work area that is clean and 1.
well-lit. The work area must not allow
access by children or pets to prevent
injury.
Locate the Compressor on a at 2.
level surface to ensure proper pump
lubrication and to prevent damage to the
unit. Keep at least 12” of space around
the unit to allow air circulation.
Route the power cord from the 3.
compressor to the grounded wall outlet,
along a safe path without creating a
tripping hazard or exposing the power
cord to possible damage.
General Operation
Close the Drain Valve (66).1.
Make sure all nuts and bolts are tight.2.
Check for oil leaks and check the oil 3.
level (See Checking the Oil).
Close the in-line Shutoff Valve between 4.
the compressor and the air hose.
Make sure the air tool’s throttle or switch 5.
in the off position.
Connect the air tool to the air hose.6.
Plug the Air Compressor Power Cord 7.
into a grounded 120 V electrical outlet.
Open the in-line Shutoff Valve.8.
Turn the Power Switch ON.9.
Allow the Air Compressor to build up 10.
pressure until it cycles off.
Note: At the beginning of the day’s rst use of
the Air Compressor, check for air leaks
by applying soapy water to connections
while the Air Compressor is pumping
and after pressure cut-out. Look for air
bubbles. If air bubbles are present at
connections, tighten connections. Do
not use the air compressor unless all
connections are air tight, the extra air
leaking out will cause the compressor to
operate too often, increasing wear on the
compressor.
Note: As long as the Power Switch is ON,
the operation of the Air Compressor
is automatic, controlled by an internal
pressure switch. The Compressor
will turn on automatically when the air
pressure drops to 95 PSI as indicated
on the Tank Pressure Gauge (53), and
will turn off automatically when the air
pressure reaches 125 PSI as indicated.
IMPORTANT: The internal pressure
switch is not user adjustable, do not
make changes to the air pressure
settings of the internal pressure
switch. Any change to the automatic
pressure levels may cause excess
pressure to accumulate, causing a
hazardous situation.
Adjust the Air Compressor’s Pressure 11.
Regulator (74) so that the air output is
enough to properly power the tool, but
the output will not exceed the tool’s
maximum air pressure at any time.
Turn the knob clockwise to increase
the pressure and counter-clockwise to
decrease pressure. Adjust the pressure
gradually, while checking the air output
gauge to set the pressure.
Use the air tool as needed.12.
