Recommended working position
The smaller the belt, the easier it can slip from the
contact wheel.
To avoid this, we recommend
- to dose the working pressure with the contact
wheel 14.
- to operate belt grinder on the pulling side 18.

• Align contact arm 15 with Nut 8 or 9.
• Mount belt 16 on contact wheel, press contact
arm firmly against flat object, observe direc-

drive wheel 7.
• Pull belt through by hand., adjust tracking with
screw 8 or 9 to stop from wandering off from
contact wheel 14. Switch on grinder, selecting
Pos 1 on variable speed selector. Make fine
adjustments, then set with Lock-in srew 10.
