SAFETY SYMBOLS
The safety symbols used on the compressor’s safety labels and in this manual provide an
important visual reminder of basic safety rules, and the hazards that may arise if all safety and
operating instructions are not followed. Make sure you understand the meaning of each of
these symbols, and protect yourself and others by obeying all safety and operating instructions
on warning labels and in this manual.
SYMBOL DESCRIPTION
SAFETY ALERT SYMBOL
Calls attention to important safety information and provides an alert to
potential safety hazards.
HOT SURFACE HAZARD
Hot surfaces can cause serious burn injury if touched. Let unit cool before
handling.
MOVING PARTS/ENTANGLEMENT HAZARD
Contact with moving parts can cause serious injury. Keep guards and
protective covers in place.
INHALATION HAZARD
Compressed air can contain carbon monoxide or other harmful gases. Do
not use compressor to provide air for breathing.
BURST HAZARD
Over-pressurization caused by tampering with controls can cause serious
injury or death from explosion.
SHOCK HAZARD
Contact with live electrical components can cause shock, serious injury, or
death from electrocution. Use a properly grounded power source.
EXPLOSION HAZARD
Electrical sparks from unit can ignite flammable liquids and vapors. Use
compressor in a well ventilated area free from explosive vapors.
FIRE HAZARD
Keep compressor 20’ feet away from spray area when spraying flammable
materials. Operate unit away from obstructions that could block ventilation.
HIGH PRESSURE AIR HAZARD
Release of pressurized air can cause serious injury if directed against body.
Never use air pressure higher than recommended for tool or accessory.

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 START OR OPERATE COMPRESSOR INDOORS OR IN POORLY VENTILATED
AREAS - Gasoline engine produce carbon monoxide, a poisonous gas that can cause death
or serious injury if inhaled. Use compressor outdoors only.
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.

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 REFUEL A HOT OR RUNNING ENGINE - Fuel vapor can be ignited by hot surfaces,
causing fire, explosion, and serious injury to operator and bystanders.
REFILL FUEL TANK OUTDOORS ONLY - Fuel vapor can be ignited by pilot lights, electronic
igniters, electric motors, and other sources of heat, sparks, or open flame. Move compressor
away from refueling area before starting to avoid fire risk from fuel spills or vapor.
DO NOT LEAV E 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.
NEVER USE A COMPRESSOR WITH A FUEL LEAK - Leaking fuel can be ignited by hot
surfaces on the unit, resulting in fire, explosion, and serious injury to operator and bystanders.
Stop using a unit with a fuel leak immediately, and shut engine off. Allow unit to cool before
handling or moving. All fuel leaks are potentially serious and must be handled with extreme
caution.

SET UP PROCEDURE
WARNING:
Before being operated with pressurized tanks for the first time, your new compressor requires
a simple set-up procedure that will help your unit deliver years of trouble-free service. Failure
to follow all initial set-up instructions may result in serious damage to your compressor,
property damage, or serious injury to operator and bystanders. Do not allow compressor to
pressurize tanks until all set-up steps have been performed.
1. Read the entire engine manual.
2. Check compressor and engine oil levels, and
fill as needed. (See #10 below)
3. Fill the fuel tank carefully, observing all safety
rules for handling gasoline. Don’t overfill leave 1/2” at filler opening for expansion.
4. Open the tank drain cock (A), or outlet valve.
5. Start the engine (see page 9), and run the
compressor for 20 minutes with drain cock
open to lubricate the bearings and pistons.
6. After 20 minutes, close the drain valve or outlet
valve.
7. Compressor is now ready for normal,
pressurized operation.
8. After first 24 hours of operation, check V-belt
tension. Correct tension setting is 1/2” of
slack when measured at midpoint between
pulleys.
9. Check bolts and nuts periodically and tighten
when necessary.
10. 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.
11. Use chart below for correct viscosity:
Air Temperature Viscosity
34 – 79° F (1 - 26° C) SAE 20W (ISO 68)
80° F & Up (27° C & Up) SAE 30W (ISO 100)
3 – 32° F (16 - 0° C) SAE 10W (ISO 32)
12. Replace oil filler plug before starting
compressor.
