to run, air pressure in the air tank
begins to build. It builds to a certain
high pressure before the motor
automatically shuts off - protecting
your air tank from pressure higher
than its capacity. The high pressure
at which the motor shuts off is called
"cut-out" pressure.

Unpacking
1. Remove all packaging.
It may be
necessary to brace
or support one side of the air
compressor when removing the
pallet because the air compressor
will have a tendency to tip.
2. Remove and discard the (4)
screws and washers holding the
compressor to the pallet.
3.

NOTE: Use an air compressor oil
such as Sears item number 9-16426
or SAE-20 (API CG/CD) heavy duty
motor oil. Under extreme winter
conditions use SAE-10 weight oil.
To Add Oil
Drain tank to
release air pressure
before removing the oil fill cap or
oil drain plug.
1. Place unit on a level surface.
2.

With the help of another person
carefully remove air compressor
from pallet and place on a level
surface.

Adding

Oil To Pump

Compressors
are
shipped without oil.
A small amount of oil may be
present in the pump upon receipt
of the air compressor. This is due
to plant testing and does not mean
the pump contains oil. Do not
attempt to operate this air
compressor without first adding oil
to the crankcase. Serious damage
can result from even limited
operation unless filled with oil and
broken in correctly. Make sure to
closely follow initial start-up
procedures.
I_[_I_
Use air compressor
oil only. MultiViscosity motor oils, like lOW 30,
should not be used in an air
compressor. They leave carbon
deposits on critical components,
thus reducing performance and
compressor life.

D30091

10_ ENG

Remove oil fill plug (A) and
slowly add compressor oil until it
is even with the top of the oil fill
hole. NOTE: Do not allow oil to
be lower than 3/8" (6 threads)
from the top at any time. When
filling the crankcase, the oil flows
very slowly into the pump. If the
oil is added too quickly, it will
overflow and appear to be full.
NOTE: Crankcase oil capacity is
approximately 16 fluid ounces.
Replace oil fill plug.

GROUNDING

INSTRUCTIONS

This product should be connected to
a metallic, permanent wiring system,
or an equipment-grounding
terminal
or lead on the product.
Grounding location is clearly
indicated on compressor.
Voltage

and Circuit

Protection

Refer to the specification chart for the
voltage and minimum branch circuit
requirements.
Risk of Unsafe
Operation. Certain
air compressors can be operated
on a 15 amp circuit if the following
conditions are met.
1. Voltage supply to circuit must
comply with the National
Electrical Code.
2.

Circuit is not used to supply any
other electrical needs.

Extension cords comply with
specifications.

D30091

Circuit is equipped with a 15
amp circuit breaker or 15 amp
time delay fuse. NOTE: If
compressor is connected to a
circuit protected by fuses, use
only time delay fuses. Time delay
fuses should be marked "D" in
Canada and "T" in the US.

If any of the above conditions cannot
be met, or if operation of the
compressor repeatedly causes
interruption of the power, it may be
necessary to operate it from a 20
amp circuit. It is not necessary to
change the cord set.
Air Distribution

System

Risk of Bursting.
Plastic or PVC pipe
is not designed for use with
compressed air. Regardless of its
indicated pressure rating, plastic
pipe can burst from air pressure.
Usa only metal pipe for air
distribution lines.
The next figure represents a typical
air distribution system. The following
are tips to remember when setting up
the air compressor's air distribution
system.
Use pipe that is the same size as
the air tank outlet. Piping that is
too small will restrict the flow of
air.
•

If piping is over 100 feet long,
use the next larger size.
Bury underground lines below
the frost line and avoid pockets
where condensation can gather
and freeze. Fill lines with air
pressure before covering to
make sure pipe joints are free
from leaks.

12- ENG

Install a flexible coupling
between the air discharge outlet
and main air distribution line to
allow for vibration.

A separate regulator is
recommended to control the air
pressure. Air pressure from the
air tank is usually too high for
individual air driven tools.

YOUR UNIT. Compare the illustrations with your unit to familiarize yourself with
the location of various controls and adjustments. Save this manual for future
reference.
Tank Pressure Gauge: The air tank
pressure gauge indicates the reserve
air pressure in the air tank.
Globe Valve: Opens and closes air
discharge valve. Turn knob counterclockwise to open and clockwise to
close.
Drain Valve: The drain valve is
located at the base of the air tank
and is used to drain condensation at
the end of each use.

On/Auto/Off Switch: Turn this switch
ON/AUTO to provide automatic
power to the pressure switch and
OFF to remove power at the end of
each use.
Pressure Switch: The pressure
switch automatically starts the motor
when the air tank pressure drops
below the factory set "cut-in"
pressure. The pressure switch stops
the motor when the air tank pressure
reaches the factory set "cut-out"
pressure.
Safety Valve: If the pressure switch
does not shut off the air compressor
at its "cut-out" pressure setting, the
safety valve will protect against high
pressure by "popping out" at its
factory set pressure (slightly higher
than the pressure switch "cut-out"
setting).

Cooling System (not shown): This
compressor contains an advanced
design cooling system. At the heart
of this cooling system is an
engineered fan. It is perfectly normal
for this fan to blow air through the
vent holes in large amounts. You
know that the cooling system is
working when air is being expelled.
Air Compressor
Pump (net shown):
Compresses air into the air tank.
Working air is not available until the
compressor has raised the air tank
pressure above that required at the
air outlet.

14_ ENG

Check Valve: When the air
compressor is operating, the check
valve is "open", allowing compressed
air to enter the air tank. When the air
compressor reaches "cut-out"
pressure, the check valve "closes",
allowing air pressure to remain inside
the air tank.

Before

First Start-up

Risk of Unsafe
Operation. Serious
damage may result if the following
break-in instructions are not
closely followed.
This procedure is required before the
air compressor is put into service the
first time and when the check valve
or a complete compressor pump has
been replaced.
Break-in Instructions
1.

Recheck all wiring. Make sure
wires are secure at all terminals
connections. Make sure all
contacts move freely and are not
obstructed.

Open the globe valve fully to
permit air to escape and prevent
air pressure build-up in the air
tank during the break-in period.

Move the On/Auto/Off lever to
"ON/AUTO" position. The
compressor will start.

Run the compressor for 20
minutes. Make sure the globe
valve is open and check tank
pressure gauge for minimal air
pressure build-up in air tank.

Check all air line fittings and
connections/piping
for air leaks
by applying a soap solution to
them. Bubbles will indicate a
leak. Correct if necessary. NOTE:
Minor leaks can cause the air
compressor to overwork,
resulting in premature breakdown
or inadequate performance.

Check for excessive vibration.
Readjust or shim air compressor
feet, if necessary.
After 20 minutes, close the globe
valve.The air tank will fill to "cutout" pressure and the motor will
stop.

To Check Safety Valve
Risk of Bursting. If
the safety valve
does not work properly, overpressurization may occur, causing
air tank rupture or explosion and
possible serious injury.
1.

Before starting compressor, pull
the ring on the safety valve to
make sure that the safety valve
operates freely. If the valve is
stuck or does not operate
smoothly, it must be replaced
with the same type of valve.
Set the On/Auto/Off lever to
"OFF" and disconnect electrical
supply.

Close the globe valve.

Remove the air tool or
accessory.

Open the globe valve and allow
the air to slowly bleed from the
air tank until tank pressure is
approximately 20 psi.

Close the globe valve.

Drain water from air tank by
opening drain valve (counterclockwise) on bottom of air tank.

If needed, slowly add oil until it
reaches the top of fill hole.
Changing

Risk of Bursting.
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 and possible
serious injury.

Risk of Bursting.
Drain air tank to
release air pressure before removing
the oil fill cap or oil drain plug.
NOTE: Use air compressor oil such
as SAE-20 (API CG/CD) heavy duty
motor oil. Under extreme winter
conditions use SAE-10 weight oil. Oil
capacity is approximately 16 fluid
ounces.
Checking
1. Remove the oil fill plug (A). The
oil level should be even with the
top of the fill hole and no lower
than 6 threads from the top of fill
hole.

To Drain Air tank

1.
2.

Remove the oil fill plug (A).
Remove the oil drain plug (B) and
drain oil into a suitable container.

Replace the oil drain plug (B) and
tighten securely.
Slowly add compressor oil until it
is even with the top of the oil fill
hole. NOTE: When filling the
crankcase, the oil flows very
slowly into the pump. If the oil is
added too quickly, it will overflow
and appear to be full.
Replace oil fill plug (A) and
tighten securely.

After the water has been drained,
close the drain valve (clockwise).
The air compressor can now be
stored.

NOTE: If drain valve is plugged,
release all air pressure. The valve
can then be removed, cleaned, then

Motor Pulley/Flywheel
Alignment
NOTE: Once the motor pulley has
been moved from its factory set
location, the grooves of the flywheel
and pulley must be aligned to within
1/16" to prevent excessive belt wear.
The air compressor flywheel and motor
pulley must be in-line (in the same
plane) within 1/16" to assure belt
retention within flywheel belt grooves.
To check alignment, perform the
following steps:
1. Disconnect electrical supply to the
air compressor
2.
3.

Remove belt guard.
Place a straightedge against the
outside of the flywheel and the
motor drive pulley.
Measure the distance between the
edge of the belt and the
straightedge at points A1 and A2
in figure. The difference between
measurements should be no more
than 1/16".

9. Reinstall belt guard.
