Checking &
Replacing V-Belt
The V-belt transfers power from the motor to the
sanding belt. If the V-belt does not have the proper
tension or is damaged in any way, the sander will
not operate optimally, and unnecessary wear on
the moving part will occur. Regularly check V-belt
tension and replace it when necessary.
