WORK AREA
1. Keep your work area clean and well lit. Cluttered benches and dark areas
invite accidents.
2. 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.
3. 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
4. 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 tool should electrically malfunction 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 tool
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.
Damaged Power Cords increase the risk of electric shock.
9. When operating a power tool outside, use an outdoor extension cord
marked“W-A”or“W”. These extension cords are rated for outdoor use, and
reduce the risk of electric shock.
PERSONAL SAFETY
10. Stay alert. Watch what you are doing, and use common sense when
operating 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.
11. 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.

SKU 93231 Page 4
12. Avoid accidental starting. Be sure the Power Switch is off before plugging
in. Plugging in power tools with the Power Switch on, invites accidents.
13. 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.
14. 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.
15. Use safety equipment. Always wear eye protection. Dust mask, non-skid
safety shoes, hard hat, or hearing protection must be used for appropriate
conditions.
TOOL USE AND CARE
16. 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.
17. Do not use the power tool if the Power Switch does not turn it on or off.
Any tool that cannot be controlled with the Power Switch is dangerous and must
be replaced.
18. 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.
19. Store idle tools out of reach of children and other untrained persons. Tools
are dangerous in the hands of untrained users.
20. Maintain tools with care. Properly maintained tools are less likely to fail and
are easier to control. Do not use a damaged tool. Tag damaged tools “Do not
use” until repaired.
21. 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.

SKU 93231 Page 5
22. 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
23. Tool service must be performed only by qualified repair personnel. Service
or maintenance performed by unqualified personnel could result in a risk of injury.
24. When servicing a tool, use only identical replacement parts. Follow
instructions in the “Maintenance” 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
1. Maintain labels and nameplates on the blower. These carry important
information. If unreadable or missing, contact Harbor FreightTools for a
replacement.
2. 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
obstructions, grease, oil, trash, and other debris. Do not use a power tool in
areas near flammable chemicals, dusts, and vapors. Do not use this product in
a damp or wet location.
3. Avoid unintentional starting. Make sure you are prepared to begin work
before turning on the blower.
4. Do not force the blower. This tool will do the work better and safer at the
speed and capacity for which it was designed.
5. Do not allow this blower to blow directly at any person or animal at close
range. Strong air flow and/or small ejected particles may cause injury.
6. Do not allow children near this Blower during use. If they put their fingers or
other objects through the protective grill, they may be injured or damage property.
7. Never hold down or disable the Circuit Breaker Reset Button. A disabled
circuit breaker results in a risk of fire.
8. Even though this is a 15 Amp circuit breaker, the total maximum draw
available in the two receptacles is 13 Amps.

SKU 93231 Page 6
9. Always unplug the blower from its electrical outlet before performing
inspection, maintenance, or cleaning procedures.
10. Keep electrical power cords and extension cords dry at all times. Do not
expose to moisture or allow them to lie on a wet surface.There is a
significant risk of electrical shock.
11. WARNING! Some dust created by power sanding, sawing, grinding, drilling,
andotherconstructionactivities, contain chemicalsknown(totheState of California)
to cause cancer, birth defects or other reproductive harm. Some examples of these
chemicalsare:leadfromlead-based paints, crystallinesilicafrombricksandcement
or other masonry products, arsenic and chromium from chemically treated lumber.
Your risk from these exposures varies, depending on how often you do this type of
work. To reduce your exposure to these chemicals: work in a well ventilated area,

12. WARNING! People with pacemakers should consult their physician(s)
before using this product. Operation of electrical equipment in close proximity to
a heart pacemaker could cause interference or failure of the pacemaker.
GROUNDING
WARNING!
Improperly connecting the grounding wire can result in the risk of electric shock.
Checkwith aqualfified electricianif youare indoubt asto whetherthe outletis properly
grounded. Do not modify the power cord plug provided with the tool. Never remove
the grounding prong from the plug. Do not use the tool if the power cord or plug is
damaged. If damaged, have it repaired by a service facility before use. If the plug will
not fit the outlet, have a proper outlet installed by a qualified electrician.
GROUNDED TOOLS: TOOLS WITH THREE PRONG PLUGS
1. Tools marked with “Grounding Required” have a three wire cord and three prong
grounding plug. The plug must be connected to a properly grounded outlet. If
the tool should electrically malfunction or break down, grounding provides a low
resistance path to carry electricity away from the user, reducing the risk of electric
shock. (See Figure A.)
2. The grounding prong in the plug is connected through the green wire inside the
cord to the grounding system in the tool. The green wire in the cord must be the
only wire connected to the tool’s grounding system and must never be attached
to an electrically “live” terminal. (See Figure A.)

SKU 93231 Page 7
3. Your tool must be plugged into an appropriate outlet, properly installed and
grounded in accordance with all codes and ordinances. The plug and outlet
should look like those in the following illustration. (See Figure A.)
FIGURE A
DOUBLE INSULATEDTOOLS:TOOLSWITHTWO PRONG PLUGS
4. Tools marked “Double Insulated” do not require grounding. They have a special
double insulation system which satisfies OSHA requirements and complies with
the applicable standards of Underwriters Laboratories, Inc., the Canadian
Standard Association, and the National Electrical Code. (See Figure B.)
5. Double insulated tools may be used in either of the 120 volt outlets shown in the
following illustration. (See Figure B.)
FIGURE B

SKU 93231 Page 8
EXTENSION CORDS
1. Grounded tools require a three wire extension cord. Double Insulated tools
can use either a two or three wire extension cord.
2. As the distance from the supply outlet increases, you must use a heavier gauge
extension cord. Using extension cords with inadequately sized wire causes a
serious drop in voltage, resulting in loss of power and possible tool damage.
(See Figure C, next page.)
3. The smaller the gauge number of the wire, the greater the capacity of the cord.
For example, a 14 gauge cord can carry a higher current than a 16 gauge cord.
(See Figure C.)
4. When using more than one extension cord to make up the total length, make
sure each cord contains at least the minimum wire size required.
(See Figure C.)
5. If you are using one extension cord for more than one tool, add the nameplate
amperes and use the sum to determine the required minimum cord size.
(See Figure C.)
6. If you are using an extension cord outdoors, make sure it is marked with the suffix
“W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.
7. Make sure your extension cord is properly wired and in good electrical condition.
Always replace a damaged extension cord or have it repaired by a qualified
electrician before using it.
8. Protect your extension cords from sharp objects, excessive heat, and damp or wet
areas.
