Description
This free-standing sanding machine drives a 2-inch wide abrasive belt vertically down behind a small table that supports the workpiece. A vertical backing plate presses back against the pressure on the workpiece. The machine has a variable-speed control and a dust collector. Its three-wheel architecture makes it easier to control the belt tension.
Please Note: If you plan to use this tool extensively, you should probably buy your own belts. The supply in the Metal Shop is limited. One way to find them is to run a Google search for: "2x48 sanding belts".

Safety Hazards
| |
|---|---|
| To turn on the dust collector, pull the red lever up. Push down to turn off. |
- ALWAYS WEAR EYE PROTECTION!! Face shield is recommended.
- Do not use the machine if you haven't been properly trained.
- ALWAYS turn on the Dust Collector before operating the machine.
- Keep fingers and hands away from the moving belt.
- When possible, grip the workpiece with vise grips to protect the hands from abrasion and excessive heat.
- Do not wear gloves. Fabric gloves can be sucked into the machine by the moving belt, causing serious hand injury.
- Beware of sparks showering from the machine during grinding.
- Do not allow piles of metal powder to accumulate inside the machine. Sparks can cause a fire.
- Do not operate the machine if the gap between the belt and the support table exceeds 1/8".
- Avoid mixing different metals on the same belt. Chemical reactions during grinding may cause a fire.
- Do not run the belt sander motor in reverse. The workpiece may be kicked into your face.
Speed Control
| |
|---|---|
| The VEVOR speed control mounted on the Burr King sander. |
Power for the Burr King sander is supplied with a toggle switch to the right of the controller. The speed control must be used to start and stop the motor, and the speed of the belt can be adjusted using it.
DO NOT attempt to change the settings unless you have been properly trained, tool-tested and you have read the user manual for the controller!
The display on the controller reads the output frequency going to the motor, not the motor speed. Unless you have done a lot of homework, this number won't have any use to you.
The motor can be started and stopped using the green and red buttons on the front panel.
Changing the Belt

The process for tensioning the belt is described on page 10 of the User Manual.
Open the door on the right side of the machine.
Press the button in the center of the tensioning handle to release the ratchet.
Move the handle down to free up the belt.
Remove the old belt and replace.
To tension, lift the handle up until the ratchet clicks several times.
