Adjusting the running wheels
If the machine only sands on one side, the surface setting must be adjusted. Following
replacement of the sanding drum or running wheels, the surface setting must always be
adjusted. To make a level, uniform setting, the sanding drum and the running wheels must
rest on the same plane. The right running wheel is adjustable. The left wheel does not adjust.
The running wheel adjustment gauge is required to adjust the machine.
For optimal results, check the grinding pattern after adjusting.
Instructions:
1. Turn the machine off.
2. Disconnect the main power cord from motor.
3. Lay the machine on its left side.
4. Use the running wheel adjustment gauge ( 4 ) to
determine the position of the left running wheel ( 1 ).
5. Loosen the lock nut ( 2 ) of the star-shaped knob on the
running gear lever behind the right wheel ( 3 ).
6. Use the running wheel adjustment gauge to adjust the right running
wheel ( 3 ) to the position of the left running wheel ( 1 ). Turn the star-
shaped knob of the right running wheel ( 3 ) until the right running
wheel ( 3 ) slightly touches the bar of the running wheel adjustment
gauge ( 4 ).
7. Tighten the lock nut ( 2 ) of the star-shaped knob on the running gear
lever beside the right running wheel.
