DANGER!
Mains voltage
– Before beginning with maintenance work, unplug
the mains plug and protect the device against being
unintentionally switched back on again!
– Indicate maintenance work with warning signs.
– Maintenance work may only be performed by spe-
cialised personnel.
– Put safety equipment back into operation after
maintenance or repair work
We recommend keeping a safety logbook
‘Safety logbook’ on page 51, where all work (mainte-
nance, repairs......) performed on the device is entered.
The most important element of maintenance is regular
cleaning:
9.1 Crushing plates
The crushing plates wear out after a certain time, depending on the
material crushed. Check the surfaces at regular intervals. For information
on turning the jaws over or replacing the jaws, observe the information
in
Chapter 6.3.1 ‘Assembling the crushing plates’ on page 29.
9.2 V-belt
To retension the V-belt, unscrew the fastening screws (4x) of the motor
on the rail; push the motor backward and then retighten the screws.
To replace the V-belt, the belt guard must be removed (9). Release the
motor and replace the V-belt (order no. 82.0290.00). Then push the
motor backward and retighten the 4 screws again as described above.
CAUTION!
Risk of injury!
The belt guard has to be attached to the device before
starting up each time.
