CHECKS RESERVED TO THE MAINTENANCE TECHNICIAN
DANGER
All the described maintenance operations in this paragraph must be carried out
with shredder stopped and with main switch disconnected and locked for safety
against undesired starting.
7.3.1
Blades
EVERY 250 WORKING HOURS
It is extremely important to check that the blades are perfectly tightened because, otherwise, they
could interfere with each other and be damaged or break.
To carry out this check – always with machine stopped and main switch disconnected and locked – first
of all, the hopper must be dismantled:
•
loosen the hopper fastening bolts;
•
hook the hopper;
•
lift it away from the shredding chamber and place it on the ground.
Carry out the following checks:
•
Check there are no spaces between the blades and spacers to be seen.
•
Check that the blades do not rotate on the shaft.
To carry out this check, give small blows to the blade circumferences with a nylon hammer
CAUTION
Do not use iron hammers or other iron tools because the blades could be
damaged and metal splinters could fly off and put the operator at risk.
If it is found that the blade unit is not perfectly tightened, the threaded rings must be tightened – see
the instructions in the following paragraphs.
