doing and use common sense
when operating this compressor.
Do not use this compressor
while you are tired or under
the inuence of drugs, alcohol
or medication. A moment of
inattention while operating a
compressor may result in serious
personal injury.
Use personal protectiveb.
equipment. Always wear eye
protection. Safety equipment
such as a dust mask, non-skid
safety shoes, hard hat, or hearing
protection used for appropriate
conditions will reduce personal
injuries.
Prevent unintentional starting.c.
Ensure the switch is in the off-
position before connecting to

Only use safety equipmentd.
that has been approved by an
appropriate standards agency.
Unapproved safety equipment may
not provide adequate protection.
Eye protection must be ANSI-
approved and breathing protection
must be NIOSH-approved for the
specic hazards in the work area.
Compressor use and care4.
Do not use the compressor if thea.
switch does not turn it on and
off. Any compressor that cannot
be controlled with the switch is
dangerous and must be repaired.
Disconnect the plug from theb.
power source before making
any adjustments, changing
accessories, or storing the
compressor. Such preventive
safety measures reduce the risk of
starting the compressor accidentally.
Store an idle compressor out ofc.

allow persons unfamiliar with the
compressor or these instructions
to operate it. A compressor is
dangerous in the hands of untrained
users.
Maintain the compressor. Keepd.
the compressor clean for better
and safer performance. Following
instructions for lubricating and
changing accessories. Keep
dry, clean and free from oil and
grease. Check for misalignment or
binding of moving parts, breakage
of parts and any other condition
that may affect the compressor’s
operation. If damaged, have the
compressor repaired before use.
Many accidents are caused by a
poorly maintained compressor.
Use the compressor ine.

GROUNDING
TO PREVENT
ELECTRIC SHOCK
AND DEATH FROM
INCORRECT GROUNDING
WIRE CONNECTION:
Check with a qualied
electrician if you are in doubt
as to whether the outlet is
properly grounded. Do not
modify the power cord plug
provided with the compressor.
Never remove the grounding
prong from the plug. Do not
use the compressor if the
power cord or plug is
damaged. If damaged, have it
repaired by a service facility
before use. If the plug will not
t the outlet, have a proper
outlet installed by a qualied
electrician.

Connect the air tool to the air hose.6.
Plug the Air Compressor Power Cord7.
into a grounded 120 V electrical
outlet.
Open the in-line Shutoff Valve.8.
Turn the compressor ON by pulling9.

Allow the Air Compressor to build up10.
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 Button is ON,
the operation of the Air Compressor
is automatic, controlled by the
internal Pressure Switch (55). The
Compressor will turn on automatically
when the air pressure drops to 80 PSI
as indicated on the Pressure Gauge,
and will turn off automatically when
the air pressure reaches 115 PSI as
indicated. IMPORTANT: The internal
Pressure Switch (55) 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’s11.
Regulator (58) 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.
After the job is complete, turn the13.

Emergency Depressurization
If it is necessary to quickly
depressurize the Compressor, turn

MAINTENANCE AND
SERVICING
Procedures not specically
explained in this manual
must be performed only by a
qualied technician.
TO PREVENT
SERIOUS INJURY
FROM ACCIDENTAL
OPERATION:
Push the Power Button “OFF”
and unplug the Compressor
from its electrical outlet
before performing any
inspection, maintenance, or
cleaning procedures.
TO PREVENT SERIOUS
INJURY FROM COMPRESSOR
FAILURE:
Do not use damaged
equipment. If abnormal noise
or vibration occurs, have the
problem corrected before
further use.
General Maintenance
BEFORE EACH USE,1. inspect
the general condition of the Air
Compressor. Check for loose
hardware, misalignment or binding
of moving parts, damaged belts,
cracked or broken parts, damaged
electrical wiring, and any other
condition that may affect its safe
operation.
AFTER USE,2. wipe external surfaces
of the compressor with a clean cloth.
3. WARNING! If the supply cord
of this compressor is damaged,
it must be replaced only by a
qualied service technician.
Maintenance Schedule
Following are general guidelines
for maintenance checks of the Air
Compressor.
Note: The environment in which the
compressor is used, and the
frequency of use can affect how
often you will need to check the
Air Compressor components and
perform maintenance procedures.
Daily:
Check oil level.a.
Check for oil leaks.b.
Make sure all nuts and bolts arec.
tight.
Drain moisture from air tank.d.
Check for abnormal noise ore.
vibration.
Check for air leaks.f. *
Wipe off any oil or dirt from theg.
compressor.**
Weekly:
Inspect Air Filter (45).a.
Inspect Oil Breather Plug.b.
Monthly:
Inspect Safety Valve (56).a.
Check belt adjustment (if provided).b.
* To check for air leaks, apply soapy
water to joints while the Air Compressor is
pressurized. Look for air bubbles.
** To clean the compressor surface, wipe
with a damp cloth, using a mild detergent
or mild solvent.

Page 15For technical questions, please call 1-800-444-3353.SKU 95386
Every 6 months or 100 Operation
Hours:
Replace Pump oil.***
Changing the Oil
Check the oil periodically for clarity.
Replace oil if it appears milky or if
debris is present, or every 6 months,
or 100 hours of runtime, whichever
comes rst.
WARNING: Risk of personal injury hazard.
Allow Air Compressor to cool before
changing the oil.
To drain the oil from the Pump
Crankcase:
Place a container under the Oil Draina.
Plug (24).
Remove the Oil Plug (31) to allow airb.
ow into the Pump.
Remove the Oil Drain Plug, allowingc.
the oil to drain into the container.
When the oil is completely drainedd.
from the Pump, replace the Oil Drain
Plug.
Fill the Pump with new compressore.
oil to the FULL level on the Oil Sight
Glass.
Replace and tighten the Oil Plug.f.
Discard the old oil according to local,g.
state and federal regulations.
*** Use Air Compressor Oil only (sold
separately - SKU 95048).
Draining Moisture from the Tank
The Drain Valve (65) is located under
the Air Tank (1). It must be accessed
daily to release all trapped air and
moisture from the Tank. This will
eliminate condensation which can
cause tank corrosion.
Note: Do not open the Drain Valve so that
more than four threads are showing.
To empty the air and condensation:
Make sure the Power Button of thea.
compressor is off.
Place a collection pan under theb.
Drain Valve.
Unthread the Drain Valve by turningc.
it counterclockwise one full turn
ONLY.
When all the pressure and moistured.
is released, close the Drain Valve.
Air Filter Maintenance
Check the Air Filter (45) weekly
to see if it needs replacement. If
working in dirty environments, you
may need to replace the lter more
often. To replace the Air Filter:
Unthread the Air Filtera.
counterclockwise.
Replace with a new Air Filter.b.
