paint solvents, paint remover,
insecticides, weed killers, may
contain harmful vapors and poi-
sons.
HOW TO PREVENT IT
Never use air obtained directly
from the compressor to supply air
for human consumption. The com-
pressor is not equipped with suit-
able filters and in-line safety equip-
ment for human consumption.
Work in an area with good cross
ventilation. Read and follow the

I__ RISK OF BURSTING
Air Tank: On February 26, 2002, the U.S. Consumer Product Safety Commission
published Release # 02-108 concerning air compressor tank safety:
Air compressor receiver tanks do not have an infinite life. Tank life is dependent
upon several factors, some of which include operating conditions, ambient con-
ditions, proper installations, field modifications, and the level of maintenance.
The exact effect of these factors on air receiver life is difficult to predict.
If proper maintenance procedures are not followed, internal corrosion to the
inner wall of the air receiver tank can cause the air tank to unexpectedly rupture
allowing pressurized air to suddenly and forcefully escape, posing risk of injury to
consumers.
Your compressor air tank must be removed from service by the end of the year
shown on your tank warning label.
The following conditions could lead to a weakening of the air tank, and result in a
violent air tank explosion:

Cut-In Pressure: While the motor is
off, air tank pressure drops as you
continue to use your accessory. When
the tank pressure drops to a certain
low level the motor will restart auto-
matically. The low pressure at which
the motor automatically restarts is
called "cut-in" pressure.
Cut-Out Pressure: When an air
compressor is turned on and begins
to run, air pressure in the air tank
begins to build. It builds to a certain
high pressure before the motor auto-
matically shuts off - protecting your
air tank from pressure higher than its

least 12" (30.5 cm) away from
the wall or other obstructions
that will interfere with the flow
of air.
Locate the air compressor as
close to the main power supply
as possible to avoid using long
lengths of electrical wiring.
NOTE: Long lengths of electri-
cal wiring could cause power
loss to the motor.
The air filter must be kept clear
of obstructions which could
reduce air flow to the air com-
pressor.
Anchoring of the Air Compressor

Wiring instructions
Risk of Electrical
' "- "---Shock. improper
electrical grounding can result in
electrical shock. The wiring should
be done by a qualified electrician
A qualified electrician needs to knows
the following before wiring:
1. The amperage rating of the electri-
cal box should be adequate. Refer
to the Specification Chart for
this information.
2. The supply line should have the
same electrical characteristics
(voltage, cycle, phase) as the
motor. Refer to the motor name-
plate, on side of motor, for this
information.
NOTE: The wiring used must be rated
for the motor nameplate voltage, plus
or minus 10%. Refer to local codes for
recommended wire sizes, correct wire
size, and maximum wire run; undersize
wire causes high amp draw and over-
heating to the motor.
_Risk of Electrical
-- Shock. Electrical
wiring must be located away from
hot surfaces such as manifold
assembly, compressor outlet tubes,
heads, or cylinders.
GROUNDING
INSTRUCTIONS
This product should be connected to
a metallic, permanent wiring system,
of an equipment-grounding terminal
or lead on the product.
Voltage and Circuit Protection
Refer to the specification chart for the
voltage and minimum branch circuit
requirements.
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.
Use 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.
NOTE: Compressed air from oil lube
air compressors will contain water
condensation and oil mist. Several
drains, traps and filters will be needed
to supply air without water (including
aerosols) or oil to spray equipment, air
tools and accessories requiring filtered
air. Always read the instructions for the
air tools and accessories being used.
• 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' (30.5 m) long,
use the next larger size.
Bury underground lines below
the frost line and avoid pockets
where condensation can gather
and freeze. Apply pressure before
underground lines are covered to
make sure all pipe joints are free
of leaks.
A flexible coupling is
recommended to be installed
between the globe valve/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 tank is usually too high for
individual air driven tools.
DO NOT install lubricators
between the tank and any spray
equipment, air tool or accessory
requiring oil-free filtered air.
Drain all traps, filters and dirt legs
daily.

KNOW YOUR AiR COMPRESSOR
READ THIS OWNER'S MANUAL AND SAFETY RULES BEFORE OPERATING
YOUR UNIT. Compare the illustrations with your unit to familiarize yourself with
the location of various controls and adjustments. Save this manual for future ref-
erence.
DESCRiPTiON OF OPERATION
Become familiar with these controls
before operating the unit.
Auto(I)/Off(O) Switch: Turn this switch
"Auto(I)" to provide automatic power
to the pressure switch and "Off(O)" 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. It stops
the motor when the air tank pressure
reaches the factory set "cut-out" pres-
sure.
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 fac-
tory set pressure (slightly higher than
the pressure switch "cut-out" setting).
Tank Pressure Gauge: The tank
pressure gauge indicates the reserve
air pressure in the tank.
Globe Valve/Air Discharge Valve:
(sold separately} Opens and closes
air distribution from compressor. See
Air Distribution System paragraph
under Installation.
Switch
Regulator (sold separately, not
shown): An air pressure regulator or a
separate air transformer which com-
bines the functions of air regulation
and/or moisture and dirt removal is
recommended for most applications.
See Air Distribution System para-
graph under Installation
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 (not 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.
13-ENG

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.
Drain
Valve
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 "clos-
es", allowing air pressure to remain
inside the air tank.
Pressure Release Valve: The pres-
sure release valve located on the side
of the pressure switch, is designed to
automatically release compressed air
from the compressor head and the
outlet tube when the air compressor
reaches "cut-out" pressure or is shut
off. The pressure release valve allows
the motor to restart freely. When the
motor stops running, air will be heard
escaping from this valve for a few sec-
onds. No air should be heard leaking
when the motor is running or after the
unit reaches "cut-out" pressure.
Reset
Release
Valve
Motor Overload Protector: This
motor has a manual thermal overload
protector. If the motor overheats for
any reason, the overload protector
will shut off the motor. The motor
must be allowed to cool down before
restarting. To restart:
1. Place the Auto/Off lever in the
"Off" position.
2. Allow the motor to cool.
3. Depress the red reset button on
the motor.
4. Place the Auto/Off lever in the

I__ Risk from Flying
__ Objects. Always
wear certified safety equipment:
ANSI 787.1 eye protection (CAN/
CSA Z94.3} with side shields.
16-ENG

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.
TO DRAIN TANK
Risk of unsafe
operation. Air tanks
contain high pressure air. Keep face
and other body parts away from
outlet of drain. Use eye protection
[ANSi Z87.1 (CAN/CSA Z94.3)] when
draining as debris can be kicked up
into face.
Risk from noise.
Use ear protection
(ANSi S12.6 ($3.19} as air flow noise
is loud when draining.
NOTE: All compressed air systems
generate condensate that accumulates
in any drain point (e.g., tanks, filter, after-
coolers, dryers). This condensate con-
tains lubricating oil and/or substances
which may be regulated and must be
disposed of in accordance with local,
state, and federal laws and regulations.
1. Set the Auto/Off lever to "Off".
2. Slowly bleed the air from the air
tank and air distribution system
until tank pressure is approximate-
ly 20 psi.
3. Drain water from air tank by open-
ing drain valve on bottom of tank.
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.
_Risk of property
damage. Drain water
from air tank may contain oil and rust
which can cause stains.
4. After the water has been drained,
close the drain valve. The air com-
pressor can now be stored.
NOTE: If drain valve is plugged,
release all air pressure. The valve can
then be removed, cleaned, then rein-
stalled.
Oil
_Risk of property
damage. Use air
compressor oil only. Multi-weight
automotive engine oils like 10W30
should not be use in air compressors.
They leave carbon deposits on
critical components, thus reducing
performance and compressor life.
NOTE: Use 30W compressor oil or a
heavy duty SAE 30W, non-detergent,
SF grade or better oil. DO NOT use
multi-weight automotive engine oils,
they will reduce compressor life. Under
extreme winter condition use SAE-10
weight oil.
NOTE: Crankcase oil capacity is
approximately 16 fluid ounces (0.47 L).
Checking
1. The oil level should be to the
middle of the sight glass (C).
2. If needed remove oil fill plug (A)
and slowly add oil until it reaches
the middle of the sight glass.
Changing
1. Remove the oil fill plug (A).
2. Remove the oil drain plug (B) and
drain oil into a suitable container.
3. Replace the oil drain plug (B) and
tighten securely.
4. Slowly add compressor oil until
the oil level is in the middle of the
sightglass (C). 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.
17-ENG

_Risk of property
damage. Overfilling
with oil will cause premature
compressor failure. Do not overfill.
5. Replace oil fill plug (A)and tighten
securely.
AIR FILTER - INSPECTION AND
REPLACEMENT
Hot surfaces.
Risk of burn.
Compressor heads are exposed
when filter cover is removed.
Allow compressor to cool prior to
servicing.
_Risk of property
damage. Keep the air
filter clean at all times. Do not operate
the air compressor with the air filter
removed.
A dirty air filter will not allow the com-
pressor to operate at full capacity.
Keep the air filter clean at all times.
1. Remove the air filter cover.
2. Remove the air filter from filter
cover.
iMPORTANT: Do not operate the
compressor with the air filter removed.
3. Place new air filter into filter cover.
Refer to the Repair Parts for the
correct part number.
4. Replace air filter cover and lock
into place.
BELT = REPLACEMENT
Risk of personal
injury. Serious
injury or damage may occur if
parts of the body or loose items
get caught in moving parts. Never
operate the outfit with the belt
guard removed. The belt guard
should be removed only when
the air compressor power is
disconnected.
1.
2.
Turn air compressor off, lock out
the power supply, and relieve all
air pressure from the air tank.
Remove the front of the belt
guard by disengaging the snaps.
Insert a flat bladed screwdriver at
each snap location and pry the
beltguard apart.
3. Loosen the wing nut on hold
down plate and tilt motor to allow
for easy removal or installation of
the belt.
4. Remove belt.
Risk of moving
parts. Use caution
when rolling belt onto flywheel,
fingers can get caught between the
belt and flywheel.
5. Replace belt. NOTE: The belt
must be centered over the
grooves on the flywheel and
motor pulley.
6. Turn the wing nut on the hold
down plate until it makes contact
with the washer, plus one
additional turn.
7. Replace the belt guard.

MOTOR PULLEY/FLYWHEEL
ALIGNMENT
NOTE: Once the motor pulley has
been moved from its factory set loca-
tion, the grooves of the flywheel and
pulley must be aligned to within 1/16"
(1.6 mm) to prevent excessive belt
wear.
The air compressor flywheel and
motor pulley must be in-line (in the
same plane) within 1/16" (1.6 mm) to
assure belt retention within flywheel
belt grooves. To check alignment, per-
form 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 against the
outside of the flywheel and the
motor drive pulley.
BELT MOTOR PULLEY I
AI= A2 (MEASURED) STRAIGHT
BI= B2 (V SUAL) EDGE
4. 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" (1.6 mm).
5. If the difference is greater than
1/16" (1.6 mm) loosen the set
screw holding the motor drive
pulley 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. See Repair Parts for
torque specifications.
7. Visually inspect the motor drive
pulley to verify that it is perpen-
dicular 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. See Repair Parts for
torque specifications.
9. Reinstall belt guard.
