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 tools 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
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.
eliminates the need for the three wire grounded power
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. 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.
12. Avoid accidental starting. Be sure the Power Switch is off before plugging in.
Carrying power tools with your finger on the Power Switch, or 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, nonskid safety
shoes, hard hat, or hearing protection must be used for appropriate conditions.
Tool Use and Care
16. 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.
17. 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.
18. 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.
19. 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.
20. Store idle tools out of reach of children and other untrained persons. Tools are
dangerous in the hands of untrained users.
21. Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained
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.
22. 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.
23. 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
24. Tool service must be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel could result in a risk of injury.
25. When servicing a tool, use only identical replacement parts. Follow instructions
in the
unauthorized parts or failure to follow maintenance instructions may create a risk of
electric shock or injury.

SPECIFIC SAFETY RULES FOR POLISHER / SANDER
1. Accessories must be rated for at least the speed recommended on the tool
warning label. Wheels and other accessories running over rated speed can fly apart
and cause injury.
2. Hold tool by insulated gripping surfaces when performing an operation where
the cutting tool may contact hidden wiring or its own cord. Contact with a “live”
wire will make exposed metal parts of the tool “live” and shock the operator.
3. Maintain labels and nameplates on the Polisher/ Sander. These carry important
information. If unreadable or missing, contact Harbor Freight Tools for a replacement.
4. Always wear ANSI-approved safety impact eye goggles and heavy work gloves
when using the Polisher/ Sander. Using personal safety devices reduce the risk for
injury. Safety impact eye goggles and heavy work gloves are available from Harbor
Freight Tools.
5. 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.
6. Make sure to read and understand all instructions and safety precautions as
outlined in the manufacturer’s manual for the vehicle you will wax/polish.
7. When using a handheld power tool, always maintain a firm grip on the tool with
both hands to resist starting torque.
8. Always keep the extension cord away from moving parts on the tool. Keep it off the
ground and away from water.
9. Avoid unintentional starting. Make sure you are prepared to begin work before turning
on the Polisher/ Sander.
10. Do not force the Polisher/Sander. This tool will do the work better and safer at the
speed and capacity for which it was designed. Do not force the pads into the vehicle
being waxed/polished. Apply moderate pressure, allowing the Bonnet to rotate freely
without being forced.
11. When waxing/polishing a vehicle, do not operate the vehicle’s engine in an enclosed
area. Carbon monoxide is a colorless, odorless, vapor emitted from a vehicle’s
(1)
running engine that may cause severe injury or death if inhaled.
12. Never lay the Polisher/Sander down until the Polishing Pad (2) has come to a full
stop. The Backing Pad can grab the surface and pull the tool out of your control.
13. Make sure the vehicle being waxed/polished is free from burrs and any other foreign
matter which could damage the tool.
14. Never leave the Polisher/ Sander unattended when it is plugged into an electrical
outlet. Turn off the tool, and unplug it from its electrical outlet before leaving.

15. Always unplug the Polisher/ Sander from its electrical outlet before performing
any inspection, maintenance, or cleaning procedures.
16. When sanding, only use 7” sanding pads with a hook and loop back that attaches
securely to the Backing Pad.
17. Connect to a GFCI. Always connect the Line Cord to a Ground Fault Circuit Interrupter
(GFCI) protected electrical outlet.
18. Never use accessories rated for less than 3500 RPM.
WARNING! Avoid serious injury. Never install carbide tipped or steel circular saw
blade for use on this Sander/Polisher. Never install a wood carving blade, carving disc
with saw chain cutters, or a cutting carving disc on this Sander/Polisher. Never install
abrasive cutoff discs and wheels, flap wheels, wire brushes, or wire wheel brushes.
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.
WARNING! Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities, contain chemicals known (to the State of California) to cause
cancer, birth defects or other reproductive harm. Some examples of these chemicals
are: lead from lead-based paints, crystalline silica from bricks and cement 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, and work with approved safety equipment, such as those dust masks that are specially designed to filter
out microscopic particles.
(California Health & Safety Code 25249.5, et seq.)
GROUNDING
WARNING!
Improperly connecting the grounding wire can result in the risk of electric shock.
Check with a qualified electrician if you are in doubt as to whether the outlet is
properly grounded. Do not modify the power cord plug provided with the tool or
product. 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.)
SKU 92623
For technical questions, please call 1-800-444-3353
English
Page 6
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.)
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
Figure B
Double Insulated Tools: Tools with Two Prong Plugs
4. This product has a polarized plug (one blade is wider than the other) as a feature
to reduce the risk of electric shock. 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. Never use with an extension cord unless plug can be
fully inserted. Do not alter the plug.
5. 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 above.)
6. Double insulated tools may be used in either of the 120 volt outlets shown in the
following illustration. (See Figure B above.)
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 Table A.)
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 Table
A.)
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 Table A.)

Page 7
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 Table A.)
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.
