Receipt and Inspection
Before signing the delivery receipt, inspect for damage and missing parts.
If damage or missing parts are apparent, make the appropriate notation
on the delivery receipt, then sign the receipt. Immediately contact the
carrier for an inspection. All material must be held in the receiving
location for the carrier’s inspection. Delivery receipts that have been
signed without a notation of damage or missing parts are considered
to be delivered “clear.” Subsequent claims are then considered to
be concealed damage claims. Settle damage claims directly with the
transportation company.
If you discover damage after receiving the air compressor (concealed
damage), the carrier must be notified within 15 days of receipt and an
inspection must be requested by telephone with confirmation in writing.
On concealed damage claims, the burden of establishing that the
compressor was damaged in transit reverts back to the claimant. Read
the compressor nameplate to verify it is the model ordered, and read the
motor nameplate to verify it is compatible with your electrical conditions.
Make sure electrical enclosures and components are appropriate.

SAFETY RULES
This is the safety alert symbol. It is used to alert
you to potential personal injury hazards. Obey
all safety messages that follow this symbol to
avoid possible injury or death.
HAZARD SYMBOLS AND MEANINGS
NOTICE indicates a situation that could result in equipment damage.
Follow safety messages to avoid or reduce the risk of injury or death.

WARNING
AIR TANK WARNING: Drain liquid from air tank
daily, or after each use, using the drain valve located
on the bottom of the lower air tank. Failure to properly
drain liquid from the tank will cause rust from moisture
buildup, which weakens the tank and could lead to a
violent tank explosion, Periodically inspect the tanks for
unsafe conditions such as corrosion.
Never attempt to repair or make modifications to the tank or its
attachments. Welding, drilling or any other modifications may weaken
the tank, which may result in damage from rupture or explosion. Never
remove or attempt to adjust the pressure switch, safety valve, or other
factory set operating pressures.
WARNING
FIRE WARNING: Avoid dangerous environments. Do
not use compressor near gasoline or other flammable
materials. Keep work area well lit. Normal sparking of
a motor or sparking from grinding metal could ignite
fumes. Do not spray flammable materials in the vicinity
of an open flame or other ignition source, including the
air compressor itself. Do not direct paint or other spray
material towards the compressor.
Read and follow all safely instructions for the material you are spraying.
Be sure to use an approved respirator designed for use with your
specific application.
WARNING
BREATHABLE AIR WARNING: This air compressor in
not designed, nor intended for the supply of breathable
quality air. Air produced by this unit may contain carbon
monoxide or other toxic vapors.
Do not inhale air from the compressor or from a breathing device
connected to it.

WARNING
ELECTRIC SHOCK WARNING: When using electric
powered tools, machines or equipment, basic safety
precautions should always be followed to minimize the
risk of electrical shock or personal injury to yourself and
others.
This air compressor is powered by electricity and should never be used
without properly grounded electrical connections. Do not use in wet or
damp locations or expose to rain.
WARNING
AIR TOOLS AND ACCESSORIES WARNING: Do
not exceed the pressure rating of any air tools, spray
guns, air accessories, or inflatables. Excess pressure
can cause them to explode, resulting in serious injury.
Follow the manufacturers recommended pressure
settings for all air tools and air accessories.
WARNING
Do not direct compressed air stream at people or pets.
The powerful compressed air stream can damage
exposed skin and easily propel loose dirt and other
small objects. Always wear eye protection that meets
ANSI Z28.1 specifications.
WARNING
Keep hands and fingers away from exposed metal parts
on a running air compressor. Air compressors generate
significant heat during normal operation, which can
cause serious burns. The compressor will remain hot for
some time after operation and should not be touched or
moved until cool.
WARNING: This product can expose you to
chemicals including lead, which is known to the
State of California to cause cancer and birth
defects or other reproductive harm. For more
information, go to www.P65Warnings.ca.gov.
Wash hands after handling.

General Safety Information
Do not operate unit if damaged during shipping, handling or use. Damage
may result in bursting and cause injury or property damage.
Since the air compressor and other components (filters, lubricators,
hoses, etc.) used, make up a high pressure pumping system, the
following safety precautions must be observed at all times:
1. Read all manuals included with this product carefully. Be thoroughly
familiar with the controls and the proper use of the equipment.
2. Follow all local electrical and safety codes
3. Only persons well acquainted with these rules of safe operation
should be allowed to use the compressor.
4. Keep visitors away and NEVER allow children in the work area.
5. Wear safety glasses and use hearing protection when operating the
pump or unit.
6. Do not stand on or use the pump or unit as a handhold.
7. Before each use, inspect compressed air system and electrical
components for signs of damage, deterioration, weakness or leakage.
Repair or replace defective items before using.
8. Check all fasteners at frequent intervals for proper tightness.
WARNING
Compressor parts may be hot even if the unit is
stopped.
9. Keep fingers away from a running compressor; fast moving and hot
parts will cause injury and/or burns.
10. If the equipment should start to abnormally vibrate, STOP the engine/
motor and check immediately for the cause. Vibration is generally a
warning of trouble.
11. To reduce fire hazard, keep engine/motor exterior free of oil, solvent,
or excessive grease. Never remove or attempt to adjust safety valve.
Keep safety valve free from paint and other accumulations.
WARNING
Motors, electrical equipment and controls can cause
electrical arcs that will ignite a flammable gas or vapor.
Never operate or repair in or near a flammable gas or
vapor. Never store flammable liquids or gases in the
vicinity of the compressor.

11
WARNING
Do not spray flammable materials in vicinity of open
flame or near ignition sources including the compressor
unit.
12. Never attempt to repair or modify a tank! Welding, drilling or any
other modification will weaken the tank resulting in damage from
rupture or explosion. Always replace worn or damaged tanks. Drain
liquid from tank daily.
13. Tanks rust from moisture build-up, which weakens the tank. Make
sure to drain tank daily and inspect periodically for unsafe conditions
such as rust formation and corrosion.
14. Fast moving air will stir up dust and debris which may be harmful.
Release air slowly when draining moisture or depressurizing the
compressor system.
Spraying Precautions
15. Do not smoke when spraying paint, insecticides, or other flammable
substances.
16. Use a face mask/respirator when spraying and spray in a well
ventilated area to prevent health and fire hazards.
17. Do not direct paint or other sprayed material at the compressor.
Locate compressor as far away from the spraying area as possible to
minimize overspray accumulation on the compressor.
18. When spraying or cleaning with solvents or toxic chemicals, follow
the instructions provided by the chemical manufacturer.
Hose Precautions
19. Inspect hose before use. Do not exceed working pressure marked
on hose. Do not twist, bend knot, or abrade hose. Do not wrap hose
around body.
20. Keep away from hot surfaces and chemicals.
WARNING
Arcing Parts. Keep the compressor/motor at least 6m
away from explosive vapour.
