DANGER: Risk of Bursting.
Tank: On February 26, 2002, the U.S. Consumer Product Safety
Commission published Release # 02-108 concerning air com-
pressor tank safety: Air air compressor receiver tanks do not
have an innite life. Tank life is dependent upon several factors,
some of which include operating conditions, ambient conditions,
proper installations, eld modications, and the level of mainte-
nance. The eect of these factors on the tank life is unpredict-
able. If proper maintenance procedures are not followed, internal
corrosion to the inner wall of the tank can cause the tank to
unexpectedly rupture allowing pressurized air to suddenly and
forcefully escape, posing risk of injury to consumers. Your air
compressor’s tank must be removed from service by the end of
the year shown on the tank warning label.
DANGER: Risk of explosion or re.

PRESSURE SWITCH
The pressure switch (not shown) automatically starts the motor
when the tank pressure drops below the factory set cut-in
pressure. It stops the motor when the tank pressure reaches the
factory set cut-out pressure.
SAFETY VALVE
This valve (A) is designed to prevent system
failures by relieving pressure from the system
when the compressed air reaches a predeter-
mined level. The valve is preset by the manu-
facturer and must not be removed or modied
in any way.
CHECK VALVE
When air compressor is operating, the check
valve (B) is open, allowing compressed air to
enter the tank. When the air compressor reach-
es cut-out pressure, the check valve closes,
allowing air pressure to remain inside the tank.

when installing or disconnecting to prevent hose whip.
1. Ensure regulated pressure gauge reads 0 PSI (0kPa).
2. Remove hose from air outlet (H) (Fig 2).
AIR COMPRESSOR LUBRICATION AND OIL
The air compressor pump was lled WITH oil at the manufactur-
er. Check pump oil level before operating unit. See Air Com-
pressor Pump Oil under Maintenance, page 21.
COMPATIBILITY
Air tools and accessories that are run o the air compressor
must be compatible with petroleum based products. If you sus-
pect that a material is not compatible with petroleum products,
an air line lter for removal of moisture and oil vapor in com-
pressed air is required.
NOTICE: Always use an air line lter to remove moisture and oil
vapor when spraying paint.
LOCATION
• Locate air compressor in a clean, dry and well ventilated
area.
• Place air compressor at least 12" (30.5 cm) away from wall
or other obstructions that will interfere with the ow of air.
• Place the air compressor as close to the main power supply
as possible to avoid using long lengths of electrical wiring.
NOTICE: Long lengths of electrical wiring could cause power
loss to the motor.
• The air lter must be kept clear of obstructions which could
reduce air ow to the air compressor.
HUMID AREAS
In frequently humid areas, moisture may form in the pump and
produce sludge in the oil, causing parts to wear out premature-
ly. Excessive moisture is especially likely to occur if the unit is
located in an unheated area that is subject to large temperature
changes. Two signs of excessive humidity are external conden-
sation on the pump when it cools down and a "milky" appear-
ance in air compressor oil. You may be able to prevent moisture
from forming in the pump by increasing ventilation or operating
for longer intervals.
ANCHORING OF THE AIR COMPRESSOR
WARNING: Risk of bursting. Excessive vibration can weaken the
tank and cause an explosion. Air compressor must be properly mounted.
The air compressor MUST be bolted to a level, solid surface.
Use 3/8" lag screws, vibration pads and anchors. If help is
needed anchoring the air compressor consult a licensed
contractor.
1. Place the air compressor on a level, solid surface. Make
sure the surface is in good condition with no cracks or
damage.
2. Mark the surface using the holes in the air compressor feet
as a template.

ELECTRICAL WIRING
WARNING: 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 national electrical code and any prevailing local electrical codes.
WARNING: 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 know the following before wiring:
1. The amperage rating of the electrical box is adequate. Refer
to the Specifications, page 8, for this information.
2. The supply line has the same electrical characteristics
(voltage, cycle, phase) as the motor. Refer to the motor
nameplate for this information.
NOTICE: 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. Undersized wire causes high amp draw and overheating to
the motor.
NOTICE: A circuit breaker is recommended. If the air
compressor is connected to a circuit protected by a fuse, use
only time delay fuses.
WARNING: Risk of electrical shock. Electrical wiring must be located
away from hot surfaces such as manifold assembly, air compressor outlet
tubes, heads or cylinders.
GROUNDING INSTRUCTIONS
WARNING: Risk of electrical shock. In the event of a short circuit,
grounding reduces the risk of shock by providing an escape wire for the
electric current. This air compressor must be properly grounded.

14
English
This product must be connected to a grounded, metallic,
permanent wiring system, or an equipment-grounding terminal
or lead on the product.
DANGER: Risk of electrical shock. Improper grounding can result in
electrical shock.
VOLTAGE AND CIRCUIT PROTECTION
Refer to the Voltage and Minimum Branch Circuit
Requirements under Specifications, page 8.
• Voltage supply to circuit must comply with the National
Electrical Code.
• Circuit is not used to supply any other electrical needs.
MAIN POWER DISCONNECT SWITCH
Install a main power disconnect switch in the line from the panel
to the air compressor. The main power disconnect switch must
be located near the air compressor, for ease of use and safety.
When turned OFF, the main power disconnect switch shuts
off all power to the air compressor. When turned ON, the air
compressor will start and stop automatically, controlled by the
pressure switch.
AIR DISTRIBUTION SYSTEM
WARNING: Risk of bursting. Plastic or PVC pipe is not designed to use
compressed air. Regardless of its indicated pressure rating, plastic pipe
can burst from air pressure. Use only metal pipe for air distribution lines.
NOTICE: Compressed air from oil lubed 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 tank outlet. Piping that is
too small will restrict the ow 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 exible 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 ltered air.
• Drain all traps, lters and dirt legs daily.

sure to build. Motor will stop when tank pressure reaches
"cut-out" pressure.
2. When the tank pressure reaches "cut-out" pressure open
the air discharge valve.
NOTICE: When using a regulator and other accessories refer to
the manufacturer’s instructions.
WARNING: Risk of bursting. If any unusual noise or vibration is noticed,
stop the air compressor immediately and have it checked by a trained
service technician.
The air compressor is ready for use.
SHUT-DOWN (Fig 5)
1. Move Auto/O switch to the OFF (0) position.
NOTICE: When finished using air compressor, follow
Steps 2 - 5.
2. Drain the tank, see Draining Tank under
Maintenance, page 20. Ensure tank pressure gauge
reads 0 PSI (0 kPa).

SHUT-DOWN (continued)
WARNING: Risk of unsafe operation. Firmly grasp air hose in hand when
installing or disconnecting to prevent hose whip.
3. Remove hose and accessory.
WARNING: Risk of bursting. Drain tank daily. Water will condense in
tank. If not drained, water will corrode and weaken the tank causing a risk
of tank rupture.
4. Allow the air compressor to cool down.
5. Wipe air compressor clean and store in a safe, non-freezing
area.
Maintenance
To ensure efficient operation and longer life of the air
compressor, a routine maintenance schedule should be
prepared and followed. The following routine maintenance
schedule is geared to an air compressor in a normal working
environment operating on a daily basis. If necessary, the
schedule should be modified to suit the conditions under which
the air compressor is used. The modifications will depend upon
the hours of operation and the working environment. An air
compressor in an extremely dirty and/or hostile environment will
require a greater frequency of all maintenance checks.

* To check for air leaks apply a solution of soapy water around joints. While air compressor is pumping to pressure and after pressure
cuts out, look for air bubbles to form.
** The pump oil must be changed after the first 20 hours of operation. Thereafter, when using full synthetic non-detergent air
compressor oil, change oil every 100 hours of operation or once a year, whichever comes first.
+ Perform more frequently in dusty or humid conditions.

WARNING: Risk of unsafe operation. Unit cycles automatically when
power is on. When performing maintenance, you may be exposed to
voltage sources, compressed air, or moving parts. Personal injuries can
occur. Before performing any maintenance or repair, disconnect power
source from the air compressor and bleed off all air pressure.
CHECKING SAFETY VALVE
WARNING: Hot surfaces. Risk of burn.Tubes, pump head, and surround-
ing parts are very hot, do not touch (see the Hot Surfaces identified in Fig.
4, page 9). Allow air compressor to cool prior to servicing.
WARNING: Risk of bursting. If the safety valve does not work properly,
over-pressurization may occur, causing tank rupture or an explosion.
WARNING: Risk from flying objects. Always wear certified safety
equipment: ANSI Z87.1 eye protection (CAN/CSA Z94.3) with side shields.
WARNING: Risk from noise. Use ear protection (ANSI S12.6 (S3.19) as air
flow noise is loud when draining.
Before starting air compressor, pull the ring
on the safety valve (A) to make sure that
the safety valve operates freely. If valve
is stuck or does not operate smoothly, it
must be replaced with the same type of
valve.
CHECKING AIR FILTER
WARNING: Hot surfaces. Risk of burn.Tubes, pump head, and surround-
ing parts are very hot, do not touch (see the Hot Surfaces identified in Fig.
4, page 9). Allow air compressor to cool prior to servicing.
A dirty air filter will not allow the air compressor to operate at full
capacity. Keep the air filter clean at all times.
1. Ensure Auto/O switch is in the OFF (0) Position.
2. Allow unit to cool.
3. Unsnap/Rotate the air lter cover to
remove (S).
4. Check the lter element. If it is dirty,
blow compressed air through the lter
element for 10-15 seconds or replace
if needed. If the lter is lled with paint, replace it.
5. Place element into housing and reattach the air lter cover.
CAUTION: Risk of unsafe operation. Do not operate without air filter.
DRAINING TANK (Fig. 5, page 9)
WARNING: Risk of unsafe operation. 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.
WARNING: Risk from noise. Use ear protection (ANSI S12.6 (S3.19) as air
flow noise is loud when draining.
NOTICE: All compressed air systems generate condensation
that accumulates in any drain point (e.g., tanks, filter,
aftercoolers, dryers). This condensate contains 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/O switch to "OFF (0)".
