CHANGING THE DRIVE BELT
Figure 20
• Using a screwdriver, remove the screws holding the
pulley cover.
• Remove the cover.
• Move the sanding belt to the vertical position as shown
in Figure 20 to access the belt tension.
• Then loosen the hex screw pressure. The vertical
positioning of the sanding strip will lessen the tension on
the belt.
• Remove the old belt.
• Place the new belt on the pulley drum motor first and
the motor pulley.
• Tighten the two strands of the belt between fingers to
measure the tension.
• Adjust the belt tension with the hex screw pressure;
when testing tension, you should observe a movement
of about 6mm.
• Tighten the tension nut of the belt.
•
Note
: Excessive tension of the drive belt may result in
motor overload and a higher noise level. Insufficient belt
tension can cause premature failure of the belt, and
noise caused by movement of the belt
• Reinstall the belt cover and use a screwdriver to screw
the guard. Tighten them.
