SAFETY INSTRUCTIONS
WEAR ANSI Z87.1 (In Canada, CSA Z94.3-99) APPROVED EYE PROTECTION - Always
wear approved eye protection equipment that provides both front and side eye protection when
operating or servicing the compressor.
DO NOT EXCEED MAXIMUM RECOMMENDED OPERATING PRESSURE OF
AIR-POWERED TOOLS OR OTHER EQUIPMENT BEING USED - Spray guns and other low
to medium pressure equipment can burst, causing serious injury to user and bystanders.
Read and follow all manufacturers' pressure recommendations before connecting tools,
sprayers, or other equipment to compressor. Use extreme care when using the compressor
with tires, inner tubes, and other inflatables, as excessive pressure or rapid inflation can cause
these items to burst.
DO NOT OPERATE IF FLAMMABLE VAPORS ARE PRESENT - The electric motor and
pressure switch may produce sparks, which can ignite flammable vapors and cause fire or
explosion. Flammable vapors from gasoline, solvents, adhesives, and other chemicals may
drift some distance from the source, or build up in low areas. Operate the compressor only in
well-ventilated areas that are free of flammable vapors.
DO NOT TOUCH COMPRESSOR MOTOR, HEAD, OR TUBING WHEN UNIT IS
OPERATING - Normal compressor operation will cause tubing and other components to
become extremely hot. Contact with hot parts can cause serious burns. Allow unit to cool
before handling or performing service.
NEVER DIRECT COMPRESSED AIR AT ANY BODY PARTS - Compressed air can penetrate
skin, or force dirt and debris into eyes, causing serious injury. Never place hands or body
parts over the air discharge opening of a pressurized nozzle or fitting. Use care when
connecting and disconnecting air hose to attachments, pneumatic tools, and other air-powered
devices.
KEEP FLAMMABLE SPRAYS AWAY FROM SPARKS AND OTHER SOURCES OF
IGNITION - Spraying flammable liquids such as oil-base paints, sealers, and finishes near
sparks, open flame, and other sources of ignition such as pilot lights, appliances, water heaters,
furnaces, etc. can result in explosion and fire. Turn off all pilot lights, and avoid using
electrical appliances, heaters, torches, and other equipment that may produce sparks or flame.
Keep compressor as far away from spraying area as possible by using an air hose of sufficient
length to prevent spray mist from being ignited by electrical sparks from compressor operation.
DO NOT OPERATE IN THE RAIN OR IN WET AREAS - Operating an electric compressor in
wet conditions can result in severe shock or electrocution. Operate only in dry conditions,
using a properly grounded power outlet that conforms to local and national electrical code
requirements. An outlet with ground-fault circuit interrupter (GFCI) protection is
recommended for use outdoors or in garages, and may be required by local electrical codes.

SAFETY INSTRUCTIONS
DO NOT TAMPER WITH COMPRESSOR PRESSURE SWITCH SETTINGS - The pressure
switch settings set at the factory provide the maximum safe operating pressure recommended
for this compressor. Altering these settings can result in over-pressurization, risk of tank,
hose, and pneumatic equipment failure, and serious injury to operator and bystanders.
USE AIR HOSE RATED FOR 150 PSI OR GREATER - Air hose must be rated to safely
handle maximum compressor pressure. Air hose that does not meet minimum pressure
requirements can rupture, releasing high pressure air. Replace a cracked or leaking air hose
immediately to prevent serious injury from contact with high pressure air streams.
SHUT OFF COMPRESSOR AND RELIEVE TANK PRESSURE BEFORE SERVICING UNIT –
Never perform service or maintenance on any part of the compressor while the unit is running
or tanks are pressurized. Open tank drains slowly to allow air to escape, and keep clear of air
stream.
DO NOT MODIFY COMPRESSOR – Altering the compressor in any way may create a serious
safety hazard, and result in serious injury to operator and bystanders. If compressor does not
work properly, stop using unit immediately. Return unit to an authorized service center for
repairs if problem cannot be remedied by following troubleshooting instructions in this manual.
DO NOT USE COMPRESSED AIR FROM THE UNIT FOR BREATHING PURPOSES - Air
produced by this compressor may contain poisonous exhaust gases from the engine, and is
not suitable for breathing purposes.
DO NOT LEAVE COMPRESSOR RUNNING UNATTENDED - Shut compressor off when done,
and disconnect air hoses to prevent unauthorized use of compressor. Drain air tanks if unit is
to be stored or transported.
CONNECT COMPRESSOR POWER CORD ONLY TO A PROPERLY GROUNDED POWER
OUTLET USING AN APPROVED 3-PRONG GROUNDED EXTENSION CORD - Using an
improperly grounded outlet or extension cord can result in shock or electrocution. Electrical
wiring, outlets, extension cords, and current protection devices such as fuses and circuit
breakers must meet local electrical and safety codes, as well the requirements of the National
Electrical Code. A ground-fault circuit interrupter (GFCI) device may be required for
compressor use outdoors, in garages, and in damp locations.
USE AN EXTENSION CORD THAT IS PROPERLY SIZED - Using an undersize cord can
result in overheating of cord and short-circuiting, resulting in fire and damage to property. Use
a UL-listed extension cord rated to safely handle the power requirements of the compressor.

unit.
2. Check compressor oil level, and fill as needed.
(See #9 below)
3. Open the tank drain cocks (A), or outlet valve.
4. Start the compressor (see page 9), and run the
compressor for 20 minutes with drain cock
open to lubricate the bearings and pistons.
5. After 20 minutes, close the drain valve or outlet
valve.
6. Compressor is now ready for normal,
pressurized operation.
7. After first 24 hours of operation, check V-belt
tension. Correct tension setting is 1/2” of
slack when measured at midpoint between
pulleys.
8. Check bolts and nuts periodically and tighten
when necessary.
9. Check oil level at sight glass (B). Oil level must
be maintained between “L” (Low) and “H” (High)
indicator lines. To add oil, remove oil filler
plug (C) and fill until sight glass shows proper
level. Change oil after first 100 hours of
operation. Add non-detergent mineral oil to
compressor.
