or if in doubt as to whether the tool is properly
grounded.
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 connect
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 properly grounded. Do not modify the
plug provided.
If it will not fit the outlet, havethe 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. Hake sure the product is
connected to an outlet having the same configuration
as the plug. An adapter should not 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. Hake 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.

back on the quick connect socket.
5. Plug the power cord into the proper receptacle.
6. Turn the Auto=On/Off switch to the On-Auto
position and the compressor will start and build
air pressure in the tank to cut-out pressure and
then shut off automatically.
7. Adjust the regulator to a PSI setting that is needed
for your application and be sure it is within the
safety standards required to perform the task. If
using a pneumatic tool, the manufacturer should
have recommendations in the manual for that
particular tool on operating PSI settings.
8. The air compressor is now ready for use. The
following inflation and cleaning accessories
packaged with this unit should only be operated
at maximum pressure of 90PSI: Blow gun,
adapter and inflation needle.
NOTE: See Accessory Kit Guide for more
information on attachment instructions.
Daily Shut=Down Procedures
1. Set the Auto=On/Off switch to the Off position.
2. Unplug the power cord from the receptacle.
3. Set the outlet pressure to zero on the regulator.
4. Remove any air tools or accessories.
5. Open the drain valve allowing air to bleed from
the tank. After all of the air has bled from the
tank, close the drain valve to prevent debris
buildup in the valve.
I
®
When draining the tank, always use ear and eye pro-
tection. Drain the tank in a suitable location; con-
densation will be present in most cases of draining.
Water that remains in the tank during storage will
corrode and weaken the air tank which could cause
the tank to rupture. To avoid serious injury, be sure
to drain the tank after each use or daily.
Maintenance
NOTE: Any service procedure not covered in the
maintenance schedule should be performed by
qualified service personnel.
The air compressor should be turned off, unplugged
from the power source, air bled from the tank and
allowed time to cool before any maintenance is per-
formed..
If air leaks after the ring has been released, or if the
valve is stuck and cannot be actuated by the ring,
do not use the air compressor until the tank safety
valve has been replaced. Use of the air compressor
in this condition could result in serious personal
injury.
To ensure efficient operation and longer life of
the air compressor unit, a routine maintenance
schedule should be followed. The following schedule
is geared toward a consumer whose compressor is
used in a normal working environment on a daily
basis.

RiNG
To check or replace air filter element,
1. Press in on air filter cap while rotating counter-
clockwise to remove filter cap.
2. Remove air filter element for visual inspection.
Loose debris or minor dust may be removed with
a soft bristle brush or compressed air. Filter
element should be replaced if it is wet, torn or
satu rated.
5. Wipe clean the inside of the filter housing before
replacing air filter.
Check the Tank Safety Valve by performing these
steps:
The tank safety valve will automatically release
air if the air receiver pressure exceeds the preset
maximum. The valve should be checked before
each day of use by pulling the ring by hand.
1. Turn the air compressor on and allow the tank to
fill. The compressor will shut off when the
pressure reaches the preset maximum.
2. Turn the air compressor off.
3. Pull the ring on the tank safety valve to release
air for three to five seconds.
4. Release the ring. Air must immediately stop
escaping when the ring is released.
Any continued loss of air after releasing the ring
indicates a problem with the tank safety valve.
Discontinue use and seek service before
continued use of the air compressor.
Storage
For storing the air compressor, be sure to do the following:
1. Turn the unit off and unplug the power cord
from the receptacle.
2. Remove all air hoses, accessories, and air tools
from the air compressor.
3. Perform the daily Maintenance Schedule as
described in the table above.
Troubleshooting Guide
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.
PROBLEM
Unusually long air tank pump up and
recovery times.
Air leaks at the check valve or at the
pressure relief valve.
POSSIBLE CORRECTION
Remove air filter cap and inspect air filter element for restrictions.
(See air filter maintenance procedure page 6)
A defective check valve results in a constant air leak at the pres-
sure relief valve when there is pressure in the tank and the com-
pressor is shut off. Drain the tank, then remove and clean or
replace the check valve.
4. Open the drain valve to bleed all air from the
tank.
5. Close the drain valve.
6. Store the air compressor in a clean and dry
location.
7. Unplug compressor, wrap the power cord on
handle.
Air leaks between head and cylinder.
Air leak from safety valve.
Pressure reading on the regulated
pressure gauge drops when an acces-
sory is used.
Excessive tank pressure.
Motor will not start.
Be sure of proper torque on head bolts. If leak remains, contact
Sears or another qualified service dealer.
Operate the safety valve manually by pulling on the ring. If the
valve continues to leak when in the closed position, it should be
replaced.
If there is an excessive amount of pressure drop when the acces-
sory is used, replace the regulator.
Adjust the regulated pressure under flow conditions (while acces-
sory is being used). It is normal for the gauge to show minimal
pressure loss during initial use of the tool.
Move the Auto-On/Off switch to the Off position. If the unit
doesn't shut off, unplug it from the power source and contact
Sears or another qualified service dealer.
Make sure the Thermal Overload Switch on the back of the motor
