GENERAL SAFETY RULES
WARNING!
READ AND UNDERSTAND ALL INSTRUCTIONS
Failure to follow all instructions listed below may
result in electric shock, re, and/or serious injury.
SAVE THESE INSTRUCTIONS
WORK AREA
Keep your work area clean and well lit.1. Cluttered benches and dark areas invite
accidents.

SKU 65903 For technical questions, please call 1-800-444-3353. Page 3
Do not operate compressors in explosive atmospheres, such as in the pres-2.
ence of ammable liquids, gases, or dust. Compressors create sparks which
may ignite the dust or fumes.
Keep bystanders, children, and visitors away while operating a compressor.3.
Provide barriers or shields as needed.
ELECTRICAL SAFETY
Grounded compressors must be plugged into an outlet properly installed1.
and grounded in accordance with all codes and ordinances. Never remove
the grounding prong or modify the plug in any way. Do not use any adapter
plugs. Check with a qualied electrician if you are in doubt as to whether the
outlet is properly grounded. If the compressors should electrically malfunction
or break down, grounding provides a low resistance path to carry electricity away
from the user.
Do not expose compressors to rain or wet conditions.2. Water entering an elec-
tric motor will increase the risk of electric shock.
Do not abuse the Power Cord.3. Never use the Power Cord to pull the Plug
from an outlet. Keep the Power Cord away from heat, oil, sharp edges, or
moving parts. Replace damaged Power Cords immediately. Damaged Power
Cords increase the risk of electric shock.
AN EXTENSION CORD MUST4. NEVER BE USED WITH THIS ITEM. Connecting
this item to an outlet through an extension cord MAY CAUSE ELECTRICAL
DAMAGE TO THE MOTOR and could present a FIRE HAZARD.
PERSONAL SAFETY
Stay alert. Watch what you are doing, and use common sense during use.1.
Do not use while tired or under the inuence of drugs, alcohol, or medica-
tion. A moment of inattention while operating may result in serious personal injury.
Dress properly. Do not wear loose clothing or jewelry. Contain long hair.2.
Keep your hair, clothing, and gloves away from moving parts. Loose clothes,
jewelry, or long hair can be caught in moving parts.
Avoid accidental starting.3. Be sure the Power Switch Lever is turned off
before plugging in. Plugging in compressors with the Power Switch Lever on,
invites accidents.
Remove adjusting keys or wrenches before turning the compressor on.4. A
wrench or a key that is left attached to a rotating part of the compressor may result
in personal injury.
Do not overreach. Keep proper footing and balance at all times.5.

SKU 65903 For technical questions, please call 1-800-444-3353. Page 4
Use safety equipment. Always wear eye protection.6. Make sure you are wear-
ing your protective clothing, safety glasses with side shields and dust mask or air
respirator, if appropriate.
TOOL USE AND CARE
Do not force the compressor. Use the correct compressor for your applica-1.
tion. The correct compressor will do the job better and safer at the rate for which it
is designed. Never attempt to force the compressor to provide more pressure than
it was designed for.
Do not use the compressor if the Power Switch Lever does not turn it on or2.
turn it off. Any compressor that cannot be controlled with the Power Switch Lever
is dangerous and must be repaired or replaced.
Disconnect the Power Cord Plug from the power source before making any3.
adjustments, changing accessories, or storing the compressor. Such preven-
tive safety measures reduce the risk of starting the compressor accidentally.
Keep idle compressors out of reach of children and other untrained persons.4.
Compressors are dangerous in the hands of untrained users.
Maintain compressors with care. Keep all components of this product clean5.
and dry. Do not use a damaged compressor. Tag damaged compressors “Do not
use” until repaired.
Check for misalignment or binding of moving parts, breakage of parts, and6.
any other condition that may affect the compressor’s operation. If damaged,
have the compressor serviced before using. Many accidents are caused by
poorly maintained compressors.
Use only accessories that are recommended by the manufacturer for your7.
model. Accessories that may be suitable for one compressor may become haz-
ardous when used on another compressor.
SERVICE
Compressor service must be performed only by qualied repair personnel. 1.
Service or maintenance performed by unqualied personnel could result in a risk of
injury.
When servicing a compressor, use only identical replacement parts. Follow2.
instructions in the “Inspection, Maintenance, And Cleaning” section of this
manual. Use of unauthorized parts or failure to follow maintenance instructions
may create a risk of electric shock or injury.

When lling the Air Compressor with oil, make sure to 2. unscrew (do not pull)
the Oil Fill Cap to remove.
Use eye and ear protection.3. Always wear ANSI-approved safety impact eye
goggles, and ear plugs when using the Air Compressor.
Make sure all tools and equipment used with the Air Compressor are rated to4.
the appropriate air pressure capacity of the Air Compressor. Do not use any
tool or equipment that does not operate from 0-115 PSI. If necessary, check the
owner’s manual of the tool or equipment for its air pressure rating.
Always disconnect the Air Compressor from its electrical outlet, release any5.
remaining air pressure from the unit, and disconnect all pneumatic tools and
equipment from the unit, before performing any services or maintenance.
Avoid injury. Never direct the air jet at people or animals.6.
Inspect safety valve daily7. . If the safety valve is not working properly, tank pres-
sure can build up to dangerous levels. The tank could explode. For this reason,
pull the ring on the safety valve before each use and verify that it operates freely.
Replace safety valve if it does not operate freely.
Never remove or alter the factory sealed Safety Release Valve.
Do not attempt to readjust the automatic start and shutoff valves.8. Any
change to the automatic ON/OFF pressure levels will cause additional stress on
the motor, which may result in shortened motor life.
Drain the Air Compressor’s air tank every day.9. Do not allow moisture to build
up inside the Air Tank.
Do not unscrew the tank drain valve so that10. more than four threads are
showing.
Avoid risk of tank explosion11. .
Avoid weakening of tank by draining condensation after each use.a.
Never modify tank by drilling holes, welding to it, or modifying it’s parts.b.
The tank is designed, and factory set, to operate within a specic pressure range. c.
For that reason, never make adjustments to, or substitute parts, to the compres-
sor.
Avoid bodily injury from moving parts12. . The compressor cycles on automatically,
without notice. For this reason, always keep hands and arms away from compres-
