Adjustment and replacement of the belts
After one hour of work, the belts heat and stretch.
Therefore, you have to re-tension them.
To check the belts, remove the cap 31, and press with
normal pressure on the belts. The displacement should
be approx. from a belt thickness.
To adjust the belts’ tension, loosen the nut (32) with the
36mm spanner. Then tighten the belts by turning the
screw (33) (clockwise: increases belt tension). Then re-
tighten the nut (32).
To change the belts, firstly remove the belt guard by
untightening the 3 screws. Loose the nut (32) and turn the
screw (33) until the belts are loose. Then put new belts on
the pulleys and make sure the pulleys are well aligned.
Re-assemble the belt guard and re-tension the belts with
the screw (33). Then re-tighten the nut (32).
Always use a matched set of belts. Do not replace single belts. After controlling or retightening
the belts, reassemble the belt guard on the frame of the machine.
