OPERATION
SELECTING SANDING BELTS
Selecting the correct size and type of sanding belt is an important step in achieving a high quality sanded finish. Alu- minum oxide, silicon carbide, and other synthetic abrasives are best for power sanding.
In general, when sanding, coarse grit removes the most ma- terial and fine grit produces the best finish. The condition of the surface to be sanded determines which grit will do the best job. If the surface is rough, start with a coarse grit and sand until the surface is uniform. Then use medium grit to remove scratches left by the coarser grit. Finally, use finer grit for finishing the surface. Always continue sanding with each grit until the surface is uniform.
USING SANDING BELTS
TO INSTALL/CHANGE SANDING BELTS
See Figures 2 - 4.
Follow these steps to install or change sanding belts.
nUnplug the sander.
WARNING:
Failure to unplug the tool could result in serious injury due to accidental starting.
nPosition the sander on its side with the cord on the left.
WARNING:
Keep hands and fingers clear of both rollers and spring mechanism at all times. Failure to do so could result in fingers getting pinched, causing serious injury.
nRaise the tension release lever.
NOTE: If you are changing sanding belts, remove the old sanding belt at this time.
nInstall the sanding belt.
CAUTION:
If the sanding belt is not a bidirectional belt, ensure that the arrow inside the belt is pointing in the direction of the rotation (clockwise when looking into the open side of the sander). Installing unidirectional sanding belts backwards can create a hazardous condition.
nAlign the sanding belt to its correct position.
nLower the tension release lever to secure the sanding belt.
