ELECTRICAL SAFETY
1. Avoid body contact with grounded
surfaces such as pipes, radiators, ranges,
and refrigerators. There is an increased risk
of electric shock if your body is grounded.
2. Do not expose power tools to rain or wet
conditions. Water entering a power tool
will increase the risk of electric shock.
3. Replace damaged cords/wiring
immediately. Damaged cords/wiring
increase the risk of electric shock.
ELECTRICAL SAFETY (EXTENSION CORDS)
WARNING: Keep the extension
cord clear of the working
area. Position the cord so
that it will not get caught
on lumber, tools, or other
obstructions while you are
working with a power tool.
Failure to do so can result in
serious personal injury.
WARNING: Check extension
cords before each use.
If damaged, replace
immediately. Never use the air
compressor with a damaged
cord since touching the
damaged area could cause
electrical shock resulting in
serious personal injury.
WARNING: Improperly
connecting the equipmentgrounding conductor can
result in a risk of electrical
shock
1. Use only 3-wire extension cords that
have 3-prong grounding plugs and
3-pole receptacles that accept the air
compressor’s plug. Make sure your
extension cord is not damaged.
2. When using the air compressor at a
considerable distance from the power
source, use an extension cord heavy
enough to carry the current that the
compressor will draw. An undersized
extension cord will cause a drop in line
voltage, resulting in a loss of power
and causing the motor to overheat.
Use the following chart to determine
the minimum wire size required in an
extension cord.
3. Only use 100 feet or less round
jacketed cords listed by Underwriter’s
Laboratories (UL).
4. When operating a power tool outside,
use an outdoor extension cord marked
“W-A” or “W”. These cords are rated
for outdoor use and reduce the risk of
electric shock.

pts-205109-051012
NOTE: Use longer air hoses
instead of long extension cords.
Your air compressor will run
better and last longer.
ELECTRICAL SAFETY
(ELECTRICAL CONNECTION)
1. This air compressor is powered by a
precision built electric motor. It should
be connected to a power supply that
is 120 volts, 60 Hz, AC only (normal
household current).
2. Do not operate this tool on direct
current (DC). A substantial voltage
drop will cause a loss of power and
the motor will overheat. If the air
compressor does not operate when
plugged into an outlet, double check the
power supply.
ELECTRICAL SAFETY (SPEED AND WIRING)
1. The no-load speed of the electric motor
varies by model and specication.
The motor speed is not constant and
decreases under a load or with lower
voltage. For voltage, the wiring in a
shop is as important as the motor’s
horsepower rating.
2. A line intended only for lights cannot
properly carry a power tool motor.
Wire that is heavy enough for a short
distance will be too light for a greater
distance. A line that can support one
power tool may not be able to support
two or three tools.
ELECTRICAL SAFETY
(GROUNDING INSTRUCTIONS)
1. This product must be grounded. In
the event of an electrical short circuit,
Safety Information (continued)
grounding reduces the risk of electric
shock by providing an escape wire for
the electric current. This air compressor is
equipped with an electric cord having an
equipment-grounding conductor and a
grounding plug. The plug must be plugged
into a matching outlet that is properly
installed and grounded in accordance
with all local codes and ordinances.
2. Check with a qualied electrician
or serviceman when the grounding
instructions are not completely
understood, or when in doubt as
to whether the product is properly
grounded. Do not modify the plug
provided. If it does not t the outlet,
have the proper outlet installed by a
qualied electrician.
3. This product is for use on a nominal
120-V circuit and has a grounding plug
illustrated in Figure 1. Only connect the
product to an outlet having the same
conguration as the plug. Do not use an
adapter with this product.

4. When proper belt tension is achieved,
tighten all four motor mounting screws.
Torque to 15-20 ft-lbs (20-27Nm).
NOTICE: Once the engine pulley
has been moved from its factory
set location, the grooves of
the ywheel and pulley must
be aligned to within 1/16”
(1.6mm) to prevent excessive
belt wear. Verify the alignment by
performing the following Pulley
and Flywheel - Alignment.

Motor Pulley/Flywheel
Alignment (Figure 8)
The air compressor ywheel and motor pulley
must be in-line (in the same plane) within
1/16” (1.6 mm) to assure belt retention
within ywheel belt grooves. To check
alignment, perform the following steps:
1. Turn air compressor off, lock out
the power supply, and relieve all air
pressure from the air tank.
2. Remove belt guard.
3. Place a straightedge (S) against the
outside of the ywheel (P) and the
motor drive pulley (R).
4. Measure the distance between the edge
of the belt (Q) and the straightedge
at points A1 and A2 in gure. The
difference between measurements
should be no more than 1/16” (1.6 mm).

5. If the difference is greater than 1/16”
(1.6 mm) loosen the set screw holding
the motor drive pulley (R) to the shaft
and adjust the pulley’s position on the
shaft until the A1 and A2 measurements
are within 1/16” (1.6 mm) of each other.
6. Tighten the motor drive pulley set screw.
7. Visually inspect the motor drive pulley
to verify that it is perpendicular to the
drive motor shaft. Points B1 and B2 of
Figure should appear to be equal. If
they are not, loosen the setscrew of the
motor drive pulley and equalize B1 and
B2, using care not to disturb the belt
alignment performed in step 2.
8. Retighten the motor drive pulley
setscrew. Torque to 145–165 in lbs
(16.4–20.3Nm).
9. Reinstall belt guard.

INSPECT AIR LINES AND
FITTINGS FOR LEAKS
1. Turn air compressor off, lock out
the power supply, and relieve all air
pressure from the air tank.
2. Apply a soap solution to all air line
ttings and connections/piping.
3. Correct any leaks found.
NOTICE: Even minor leaks can
cause the air compressor to
overwork, resulting in premature
breakdown or inadequate
performance.

Maintenance (continued)
Storage
Before you store the air compressor, make sure you do the following:
1. Review the Maintenance section on the preceding pages and perform scheduled
maintenance as necessary.
2. Drain water from air tank. See To Drain Tank under Operation.
WARNING: Water will condense
in the air tank. If not drained,
water will corrode and weaken
the air tank causing a risk of air
tank rupture.
Troubleshooting
Problem Possible Cause Solution
Compressor does
not run.
Tank has insufcient
pressure.
When the tank pressure drops, the
compressor will turn on to cut-in
pressure.
No electrical power. Verify wiring connection inside
pressure switch and terminal box
area.
Blown stop/house fuse. Replace the shop/house fuse.
Tripped shop/home
breaker.
Reset the shop/home breaker and
determine the underlying cause.
Thermal overload is open. Place the Auto/Off switch in the
“Off” position.
Allow the motor to cool.
Depress the red reset button on
the motor.
Place the Auto/Off switch in the
“Auto” postion to restart the
motor.

Troubleshooting (continued)
Oil and/or moisture
in tank and/or air
lines
Water condensation
Oil blow-by in pump
It is normal for oil lube air
compressor pumps to release some
oil into the tank and air lines. Air
compressors will also generate
water condensation that will form
in the tank and air lines. Install
water and oil lter traps when
needed. The Typical Compressed
Air Distribution System provides
a guideline. Contact a call Husky
Customer Service for more
information.
IMPORTANT: If the tank or air
lines have excessive water and/
or oil, bring the compressor to a
service center.
