8.5 Replacing the side cutter knife
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.
Please note:
the grinding angle of the side cutter knife is 40°!
To replace the cutter knife follow the instructions below:
• Release (without fully removing) the 4 fixation screws (SW15) and
remove the upper infeed hopper (see figure 27). When doing this,
remember to first pull out the threaded stud of the safety switch.
• Remove the side spout by releasing the 4 hex screws (SW 13)
(see „Fig. 28“)
• Turn the rotor till the knife becomes visible through the opening
(see „Fig. 29“).
• Release the countersunk screw (SW 5) of the knife and pull it out
Please note:
countersunk screws are securely seated by means
of high resistance hardware loctite. Before attempting to remove
them, use an hot air gun (or similar tools) to warm them up.
• Replace the knife.
• Secure all knife countersunk screws using high resistance thread
glue.
• After replacing the cutter knife, firmly screw the side spout back in
place (see „Fig. 28“)
• Hand turn the rotor to make sure that no hammer hits against the
shredder walls or other components and in that case grind excess
material off.
• Reassemble the upper hopper and make sure that the threaded stud
fits back into the safety contact holder, tighten all 4 hex screws (SW
15) by the original torque (see „Figure 27“).
• Turn the threaded stud inside the contact holder (see „Fig. 30“)
• Start the shredder
• Failure of the machine to properly start, turn the stud to further
progress inside the contact holder turn until the safety switch is en-
gaged.
