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