8 Maintenance
8.1 Crushing plate
Depending on the materials to be crushed, crushing jaws are subject to abrasion.
They should be checked within certain intervals and should be eventually turned
upside-down or be replaced (see chapter 5.2).
8.2 V-belts
To re-tighten the V-belts, the fastening screws (4 pieces) of the
motor on its rail are loosened, the motor is pushed to the back and
the screws are firmly re-tightened.
To replace the V-belts, the belt guard (9) must be removed.
Loosen the motor and replace the V-belts (Order-No. 82.0170.00).
Then push back the motor and re-tighten the 4 screws as
mentioned above.
8.3 Greasing the bearings
The guide bolt (3) and the link pin (6) should after approximately 500 working hours
be cleaned and greased with machine oil
. Two grease nipples are located on the
movable crushing jaw (21) for greasing of the bearings of the main shaft. These
bearings have to be greased after approximately 500 working hours with roller
bearing grease (i. e. as to DIN 5l806). All other bearings are coated with a
permanent lubricant.
