Sanding
The sander can be used for most sanding operations on materials such as wood, plastic, metal and painted surfaces.
WARNING : Don’t use this machine on plaster.
Wear safety goggles and dust mask.
Where possible, secure smaller workpiece to prevent them from moving under the sander. Lower the sander in contact with the workpiece without
pressure and then start the sander.
Move the sander slowly over the surface of the workpiece, for best results use the sander in a linear motion not circular. Using the sander in a circular
motion may result in the belt tracking slipping. Sand with the grain, in parallel over lapping strokes.
To remove paint or smooth very rough wood, sand across the grain at 45º in two directions, and then finish parallel with the grain. Use the front roller
only to sand corners or irregular shapes.
Lift the sander off the work before switching off. Remember to keep your hands away from the moving belt, as it will continue to move for a short
time after the machine is switched off.
If there are still scratches on your work after sanding, try either of the following:
- Go back to a coarser grit and sand the marks out before recommencing with the original choice or,
- Try using new sanding belt of the same grit to eliminate the unwanted marks before progressing to a finer grit and finishing the job.
