3.  
4.  
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 malfunction or  
break down, grounding provides a low resistance path to carry electricity away  
from the user.  
5.  
6.  
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.  
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.  
8.  
Do not expose power tools to rain or wet conditions. Water entering a power  
tool will increase the risk of electric shock.  
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 immedi-  
ately. 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 oper-  
ating a power tool. Do not use a power tool while tired or under the influ-  
ence of drugs, alcohol, or medication. A moment of inattention while operat-  
ing power tools may result in serious personal injury.

15.  
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 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.  
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. Dust mask, non-skid  
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.  
18.  
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 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.  
21.  
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  
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.  
SKU 45813

22.  
23.  
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 main-  
tained 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  
24.  
25.  
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  
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.  
SPECIFIC SAFETY RULES  
1.  
2.  
Maintain labels and nameplates on the Polisher/Waxer. These carry impor-  
tant information. If unreadable or missing, contact Harbor Freight Tools for a  
replacement.  
Always wear safety impact eye goggles and heavy work gloves when using  
the Polisher/Waxer. Using personal safety devices reduce the risk for injury.  
Safety impact eye goggles and heavy work gloves are available from Harbor  
Freight Tools.  
3.  
4.  
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.  
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.  
5.  
6.  
When using a hand-held power tool, always maintain a firm grip on the tool  
with both hands to resist starting torque.  
Always keep the extension cord away from moving parts on the tool.  
SKU 45813  
PAGE 5  
 
7.  
8.  
Avoid unintensional starting. Make sure you are prepared to begin work  
before turning on the Polisher/Waxer.  
Do not force the Polisher/Waxer. This tool will do the work better and safer at  
the speed and capacity for which it was designed. Do not force the rotating Pad  
(part #26) into the vehicle being waxed/polished. Apply moderate pressure,  
allowing the Pad to rotate freely without being forced.  
9.  
When waxing/polishing a vehicle, do not run the vehicle in an enclosed  
area. Carbon monoxide is a colorless, odorless, vapor emitted from a vehicle’s  
running engine that may cause severe injury or death if inhaled.  
10.  
Never lay the Polisher/Waxer down until the Rotating Pad (part #20)  
has come to a complete stop. The Rotating Pad can grab the surface and pull  
the tool out of your control.  
11.  
12.  
Make sure the vehicle being waxed/polished is free from burrs and any  
other foreign matter which could damage the tool.  
Never leave the Polisher/Waxer unattended when it is plugged into an  
electrical outlet. Turn off the tool, and unplug it from its electrical outlet before  
leaving.  
13.  
14.  
Always unplug the Polisher/Waxer from its electrical outlet before perform-  
ing and inspection, maintenance, or cleaning procedures.  
WARNING! Some dust created by power sanding, sawing, grinding, drilling,  
and other construction activities, contain chemicals known (to the State of Cali-  
fornia) to cause cancer, birth defects or other reproductive harm. Some ex-  
amples 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 qualfified 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. 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 elec-  
tric shock. (See Figure A.)  
2.  
3.  
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.)  
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  
SKU 45813  
PAGE 7  
 
DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS  
4.  
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.)  
Double insulated tools may be used in either of the 120 volt outlets shown in the  
following illustration. (See Figure B.)  
FIGURE B  
EXTENSION CORDS  
1.  
2.  
Grounded tools require a three wire extension cord. Double Insulated tools  
can use either a two or three wire extension cord.  
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.  
4.  
5.  
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.)  
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.)  
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.)  
SKU 45813  
PAGE 8  
 
6.  
7.  
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.  
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.

INSPECTION, MAINTENANCE, AND CLEANING  
1.  
2.  
WARNING! Make sure the Power Switch (part #13) of the Polisher/Waxer  
is in its “OFF” position and that the tool is unplugged from its electrical outlet  
before performing any inspection, maintenance, or cleaning procedures.  
BEFORE EACH USE, inspect the general condition of the Waxer/Polisher.  
Check for loose screws, misalignment or binding of moving parts, cracked or  
broken parts, damaged electrical wiring, and any other condition that may affect  
its safe operation. If abnormal noise or vibration occurs, have the problem cor-  
rected before further use.  
Do not use damaged equipment.  
3.  
The most common error when waxing/polishing a vehicle is applying too much  
wax. If the Pad (part #26) becomes saturated with wax, polishing will be more  
difficult and will take longer. Applying too much wax may also reduce the life of  
the Pad. If the Waxing Bonnet (part #28) continually comes off the Pad during  
use, too much wax may have been applied.  
4.  
5.  
Remove the Waxing/Polishing Bonnets (part #28, #29) from the Pad (part #26)  
when the Waxer/Polisher is not in use. This will allow the Pad to dry and retain  
its original shape.  
To prolong Pad (part #26) life and shape, store the Waxer/Polisher with the Pad  
face up.  
SKU 45813
