WORK AREA
Keep your work area clean and well lit. Cluttered benches and dark areas invite
accidents.
Do not operate power tools in explosive atmospheres, such as in the
presence of flammable liquids, gases, or dust. Power tools create sparks
which may ignite the dust or fumes.
Keep bystanders, children, and visitors away while operating a power tool
Distractions can cause you to lose control. Protect others in the work area from
debris such as chips and sparks. Provide barriers or shields as needed.

ELECTRICAL SAFETY
Grounded tools must be plugged into an outlet properly installed 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 qualified electrician if you are in doubt as to
whether the outlet is properly grounded. If the tools should electrically malfunc-
tion or break down, grounding provides a low resistance path to carry electricity
away from the user.
5. Double insulated tools are equipped with a polarized plug (one blade is wider
than the other). This plug will fit in a polarized outlet only one way. If the plug
does not fit fully in the outlet, reverse the plug. If it still does not fit, contact
a qualified electrician to install a polarized outlet. Do not change the plug
in any way. Double insulation eliminates the need for the three wire grounded
power cord and grounded power supply system.
6. Avoid body contact with grounded surfaces such as pipes, radiators, ranges,
and refrigerators. There is an increased risk of electric shock if your body is
grounded.
7. Do not expose power tools to rain or wet conditions. Water entering a power
tool will increase the risk of electric shock.
8. Do not abuse the Power Cord. Never use the Power Cord to carry the tools or
pull the Plug from an outlet. Keep the Power Cord away from heat, oil, sharp
edges, or moving parts. Replace damaged Power Cords immediately. Dam-
aged Power Cords increase the risk of electric shock.
PERSONAL SAFETY
Stay alert. Watch what you are doing, and use common sense when operat-
ing a power tool. Do not use a power tool while tired or under the influence
of drugs, alcohol, or medication. A moment of inattention while operating power
tools may result in serious personal injury.
Dress properly. Do not wear loose clothing or jewelry. Contain long hair.
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. Be sure the ON/OFF Knob (86) is off before plug-
ging in. Plugging in power tools with the ON/OFF Knob on, invites accidents.
Remove adjusting keys or wrenches before turning the power tool on. A wrench or
a key that is left attached to a rotating part of the power tool may result in personal
injury.

Do not overreach. Keep proper footing and balance at all times. Proper footing
and balance enables better control of the power tool in unexpected situations.
Use safety equipment. Always wear eye protection. Always wear
ANSI approved safety impact goggles when using this product. Hearing
protection must be used for appropriate conditions.
TOOL USE AND CARE
Use clamps (not included) or other practical ways to secure and support
the workpiece to a stable platform. Holding the work by hand or against your
body is unstable and may lead to loss of control.
Do not force the tool. Use the correct tool for your application. The correct
tool will do the job better and safer at the rate for which it is designed.
Do not use the power tool if the ON/OFF Knob (86) does not turn it on or off.
Any tool that cannot be controlled with the Power Switch is dangerous and must
be replaced.
Disconnect the Power Cord Plug from the power source before making any
adjustments, changing accessories, or storing the tool. Such preventive safety
measures reduce the risk of starting the tool accidentally.
Store idle tools out of reach of children and other untrained persons. Tools
are dangerous in the hands of untrained users.
Maintain tools with care. Keep cutting tools sharp and clean. Properly main-
tained tools with a sharp cutting edge are less likely to bind and are easier to control.
Do not use a damaged tool. Tag damaged tools “Do not use” until repaired.
Check for misalignment or binding of moving parts, breakage of parts, and any
other condition that may affect the tool’s operation. If damaged, have the tool
serviced before using. Many accidents are caused by poorly maintained tools.
Use only accessories that are recommended by the manufacturer for your
model. Accessories that may be suitable for one tool may become hazardous
when used on another tool.
SERVICE
Tool service must be performed only by qualified repair personnel. Service
or maintenance performed by unqualified personnel could result in a risk of injury
When servicing a tool, use only identical replacement parts. Follow in-
structions 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.

SPECIFIC SAFETY RULES
WARNING! Your Warranty is voided if:
You do not put compressor oil in the Compressor’s crankcase prior to its
first use. Before each use, check the oil level. Never run the Compressor
with low or no compressor oil. Running the Compressor with low or no
oil will permanently damage the unit.
You use an extension cord with the Air Compressor. Connect the Air
Compressor’s Power Cord Plug directly to the nearest 120 volt, grounded,
electrical outlet. If necessary, attach a longer air hose to the Compressor.
You drop the Air Compressor. Do not lift the Air Compressor using its
Handle.
This Air Compressor may require a dedicated electrical circuit, as the amper-
age draw under full load combined with use of any other item may overload
your circuit.
Maintain labels and nameplates on the Air Compressor. These carry important
information. If unreadable or missing, contact Harbor Freight Tools for a replace-
ment.
Always wear ANSI-approved safety impact eye goggles when assembling and
using the Air Compressor.
Maintain a safe working environment. Keep the work area well lit. Make sure
there is adequate surrounding workspace. Always keep the work area free of ob-
structions, grease, oil, trash, and other debris.
DANGER! This Air Compressor is NOT equipped and should not be used “as is”
to supply breathing quality air. For any application of air for human consumption,
you must fit the Air Compressor with suitable inline safety and alarm equipment
(not included). This additional equipment is necessary to properly filter and purify
the air to meet minimal specifications for Grade D breathing as described in Com-
pressed Gas Association Commodity Specification G 7.1-1966, OSHA 29 CFR
1910. 134, and/or Canadian Standards Associations (CSA). In the event the Air
Compressor is used for the purpose of breathing air application and proper inline
safety and alarm equipment is not simultaneously used, existing warranties are void,
and Harbor Freight Tools disclaims any liability whatsoever for any loss, personal
injury, or damage.
DANGER! Never attempt to repair or modify the Tank (50). Welding, drilling, or
any other modification will weaken the Tank resulting in damage from rupture or
explosion. Always replace worn, cracked, or damaged Tanks.
