WIRING INSTRUCTIONS
Improper electrical installation of this product may void its warranty
and your fire insurance. Have circuit wiring performed by qualified personnel such
as a licensed electrician who is familiar with the current national electrical code and
any prevailing local electrical codes.
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 electrical box should be adequate. Refer to the
Specifications, in the parts manual, for this information.
2. The supply line should have the same electrical characteristics (voltage, cycle,
phase) as the motor. Refer to the motor nameplate, on side of motor, for this
information.
NOTE: The wiring must be the same as 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 overheating 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 Specifications for the voltage and minimum branch circuit
requirements.
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.
3. Extension cords comply with specifications.
4. 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. Use only metal pipe for air distribution lines.

Auto(I)/Off(0) Switch: Turn this switch in the "Auto (I)" position to provide auto-
matic 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" 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).
Tank Pressure Gauge: The tank pressure gauge indicates the reserve air pres-
sure in the tank.
Globe Valve/Air Discharge Valve: (sold separately, not shown) Opens and
closes air distribution from compressor. See Air Distribution System paragraph
under Installation.
Regulator (sold separately, not shown): An air pressure regulator or a separate
air transformer which combines the functions of air regulation and/or moisture and
dirt removal is recommended for most applications. See Air Distribution System
paragraph 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 per-
fectly 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.

conditions under which your compressor is used. The modifications will depend
upon the hours of operation and the working environment. Compressor outfits in
an extremely dirty and/or hostile environment will require a greater frequency of all
maintenance checks.
NOTE: See Operation section for the location of controls.
TO CHECK SAFETY VALVE
Risk of bursting. If the safety valve does not work properly,
over-pressurization may occur, causing air tank rupture or an explosion.
Risk from flying objects. Always wear certified safety equip-
ment: ANSI Z87.1 eye protection (CAN/CSA Z94.3) with side shields.
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.

15 - ENG
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 (S3.19) 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, aftercoolers, dryers). This condensate contains lubricat-
ing oil and/or substances which may be regulated and must be disposed of in accor-
dance 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 approximately 20 psi.
3. Drain water from air tank by opening 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 compressor
can now be stored.
NOTE: If drain valve is plugged, release all air pressure. The valve can then be
removed, cleaned, then reinstalled.
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
C
B
A
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 tight-
en 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.

16 - 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.
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 compressor pump to operate at full capacity.
Before using the compressor pump, check the air filter to make sure it is clean
and in place.
If it is dirty, replace it with a new filter.
1. Using a pair of needle nose pliers or a screwdriver pull or pry out the old
filter and carefully clean the filter area.
2. Push the new air filter in place.
IMPORTANT: Do not operate the compressor with the air filter removed.
BELT - REPLACEMENT
Risk of unsafe operation. 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. Turn air compressor off, lock out the power supply, and relieve all air pres-
sure from the air tank.
2. 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.
Belt Guard
Wing Nut
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 fly-
wheel, 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.

17 - ENG
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" (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, 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 against the
outside of the flywheel and the motor
drive pulley.
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.
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 70-100 in-lbs
(7.9-11.3 Nm).
9. Reinstall belt guard.
AIR COMPRESSOR PUMP INTAKE AND EXHAUST VALVES
Once a year have a Trained Service Technician check the air compressor pump
intake and exhaust valves.
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 fittings and connections/piping.
3. Correct any leaks found.
IMPORTANT: Even minor leaks can cause the air compressor to overwork,
resulting in premature breakdown or inadequate performance.
AIR COMPRESSOR HEAD BOLTS - TORQUING
The air compressor pump head bolts should be kept properly torqued. Check
the torques of the head bolts after the first five hours of operation. Torque to
28–39 ft.-lbs (38.0-52.9 Nm).
