IMPORTANT SAFETY INSTRUCTIONS
Warning: Read and understand all instructions. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious personal injury.
READ THESE INSTRUCTIONS
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, 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.
ELECTRICAL SAFETY
- 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 outdoor extension cord marked “W-A” or “W”. These cords are rated for outdoor use and reduce the risk of electric shock

OPERATION INSTRUCTIONS
ON/OFF TRIGGER
Press the ON/OFF trigger to turn the unit ON. Release it to turn the unit OFF.
SPEED CONTROL DIAL
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.
SPINDLE LOCK BUTTON
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.
POLISHING
- Make sure the surface to polish has been thoroughly washed, and is free of dust, dirt, oil, grease, etc.
- Place a clean foam pad (sold separately) securely Onto the backing pad.
- 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. - Rotate the Speed Dial to select the desired speed between 1 and 5.
- 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.
- Plug the power cord into an electrical extension cord (not included). Then, plug the extension cord into a grounded, GFCI-protected, 120 volt electrical outlet.
- Note: always start and stop the polisher/sander while it is held firmly against the surface of the vehicle. Failure to do so may result in the foam pad or polishing bonnet being thrown from the polishing pad.
- To start, position the unit on the area to be polished, grip the polisher/sander firmly with both hands and press the trigger. Release the trigger to stop. To use the lock on button, while holding in the trigger, press the lock on button, then release the trigger. The polisher/sander will stay on. Press and release the trigger to stop.
- Keep pressure off of the polisher/sander when operating. The foam pad should LIGHTLY contact the polishing surface.

- Add additional wax to the polishing pad as needed. To add additional wax:
- Stop the tool and allow the polisher/sander to come to a complete stop.
- Add a small amount of wax evenly over the pad surface.
- Avoid using too much wax. For additional applications of wax to foam pad, reduce the amount of wax. The foam pad will not absorb as much wax in subsequent applications.
- Resume operation.
- 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.
- After the wax has been applied to the vehicle’s surface, turn off the polisher/sander. Unplug the power cord from the electrical extension cord.
- Remove the foam pad from the backing pad and with your hand and the foam pad, apply wax to any hard to reach areas of the vehicle such as around lights, door handles, under bumpers, etc.
