To replace a worn out V-belt or simply to stretch it, release (but do
not pull out) the 4 adjustment screws (SW 13 or 17) of the motor ba-
se plate (see „Fig. 15“).
To stretch a loose V-belt, simply tighten the tensioning screws (SW
17) located on the motor base plate and turn them towards the motor
mount (see „Figure 16“) after having released the lock nut (SW 17).
Now stretch the V-belt till it will sag by approx 10 mm under the pres-
sure of one finger, (see „Figure 17“).
The motor must be parallel to the outer profile of the motor bedplate.
Finally tighten again all 4 screws (SW 13 and SW 17) to operate the
motor again.
To replace a worn out V-belt, release the 4 adjustment screws (SW
17) so that it will be possible to move the motor back towards the ro-
tor.
Dismount the V-pulley off the belt pulleys.
Now, fit a new one in and provide due tensioning as described above.
Tighten and secure all 4 fixation screws (SW 13 and SW 17).
After complete stretching of the V-belt fit the cover back in place on
the chipper.
8.4 Replacing the hammers
Attention! Always use safety work gloves! Strictly perform
maintenance, repair and cleaning services after you have suc-
cessfully disconnected power and after all moving parts on the
machine have come to a complete still stand.
As soon as you detect a reduction of the chipper output and producti-
vity, check the hammers and eventually perform regrinding or repla-
cing.
