Read and understand all instructions. Failure to
follow all instructions listed below may result in
electric shock, fire, and/or serious personal injury.
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 flamma-
ble liquids, gases, 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.
Avoid accidental starting. Be sure switch is
offbefore plugging in. Carrying tools with your
finger onthe switch or plugging in tools that have the
switch on invites accidents.
Remove adjusting keys or wrenches before
turning the tool on. A wrench or a key that is left
attached to a rotating part of the 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 tool in unexpected
situations.
Use safety equipment. Always wear eye protec-
tion. Dust mask, nonskid safety shoes, hard hat, or
hearing protection must be used for appropriate
conditions.
Do not wear loose clothing or jewelry. Contain
long hair. Loose clothes, jewelry, or long hair can be
drawn into air vents.
Do not use on a ladder or unstable support.
Stable footing on a solid surface enables better
control of the tool in unexpected situations.
Use clamps or other practical way to secure
andsupport 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 tool. Use the correct tool for your
appli-cation. The correct tool will do the job better
and safer at the rate for which it is designed.
Do not use tool if switch does not turn it on or
off. Any tool that cannot be controlled with the
switch is dangerous and must be repaired.
Disconnect the plug from 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 the 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
sharp cutting edges are less likely to bind and are
easier to control.
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.
Keep the tool and its handle dry, clean and free
from oil and grease. Always use a clean cloth when
clean-ing. Never use brake fluids, gasoline,
petroleum-based products, or any strong solvents
to clean your tool.Following this rule will reduce the
risk of loss of control and deterioration of the
enclosure plastic.
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.

To reduce the risk of fire or electric shock, do not
ex-pose this product to rain or moisture. Store
indoors.
Do not abuse the cord. Never use the cord to carry
the tools or pull the plug from an outlet. Keep cord
away from heat, oil, sharp edges, or moving parts.
Replace damaged cords immediately. Damaged
cords increase the risk of electric shock.
When operating a power tool outside, use an
outdoorextension cord marked “W-A” or “W”.
These cords are rated for outdoor use and reduce the
risk of electric shock.
Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use tool while tired or under the influence of
drugs, alcohol, or medication. A moment of inatten-
tion 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.

Read all safety warnings and all instructions. Failure to
follow the warnings and instructions may result in electric
shock, fire and/or serious injury. Save all warnings and
instructions for future reference.
The term “power tool” in the warnings refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.

Press the ON/OFF trigger to turn the unit ON.
Release it to turn the unit OFF.
The speed control dial features 5 settings
(numbered 1 to 5 on the dial), allowing you to
increase or decrease speed from 1,500 to 4,000
RPM. Optimal speed setting for each application is
dependent on work surface and personal
preference; however manufacturer recommends
using lower settings for waxing/polishing and
higher settings for sanding. As a rule, when
sanding, you will generally want to use a higher
setting on harder materials and lower setting on
softer materials. It is also recommended that you
first experiment on a piece of scrap of the same
material as your work surface to determine what
gives you the best combination of finish quality and
removal rate for your application.


A spindle lock button has been provided for locking
the spindle of your tool in a stationary position.
Depress and hold the lock button while installing,
changing, or removing accessories.
1. Make sure the surface to polish has been thoroughly
washed, and is free of dust, dirt, oil, grease, etc.

Onto the backing pad.
3. Apply about two tablespoons of wax (not included)
Evenly on the clean foam pad.
CAUTION! Do not apply the wax directly to the surface of
the vehicle. The amount of wax needed will vary
according to the size of the vehicle being waxed.
NOTICE: Only use the slower speeds for polishing.
Otherwise, damage may occur to the paint being
polished. WORKPRO Tools is not responsible for
damage to the vehicle’s finish due to improper use of
this polisher/sander.

bonnet (sold separately) securely onto the foam pad.
Add additional wax to the polishing pad as
needed. To add additional wax:
Note: The most common error when
waxing/polishing a vehicle is applying too much wax.
If the Foam Pad becomes saturated with wax,
applying wax will be more difficult and will take
longer. Applying too much wax may also reduce the
life of the Foam Pad. If the Foam Pad continually
comes off the Backing Pad during use, too much
wax may have been applied.
Note: Tightly pull the string to secure the polishing
bonnet. Secure the string and keep it out of the way
by tying several knots.
Note: Start and stop the polisher/sander only while it
is held firmly against the surface of the vehicle.
