6. Operation and daily maintenance

6.1 Starting and stopping

The start and stop functions are controlled by a change-over button on the
electrical cabinet.
NOTE: The granulator should not be stopped until it has finished grinding all
the material in the hopper and cutter housing. Any remaining material can slow
down the rotor when it is re-started which can overload the motor and trigger
the overload protector. (See 6.4)

6.2 Inspection

There should not be any material in the granulator when the inspection is to be
carried out.
6.2.1 Daily inspection
•Flaps in the hopper. Check that the flaps are not damaged. Damaged parts
should be replaced immediately to prevent bits of the flaps from falling into
the cutter housing and damaging the knives. There is also a risk that
damaged flaps can be thrown back by the machine.
• Emergency stop. Check the emergency stop function by starting the
granulator and then stopping it using the emergency stop button. The
emergency stop is reset by turning the emergency stop button in the
direction of the arrow. The machine can then be re-started by pressing
“START”.
6.2.2 Weekly inspection
•Cables. Inspect all cabling in the machine to see that there is no wear or
other damage. For reasons of personal
protection, damaged parts should be replaced
immediately.
•Safety switches. There are two safety
switches, one for the screen box and one for
the hopper:
Screenbox: Check the safety switch by starting
the granulator and then unscrewing the break
screw (A) on the bottom of the belt guard, as
described in chapter 5.2. The granulator should
have stopped before you are able to open the
screenbox.
Hopper: Open the hopper as described in chapter 5.2, but close and lock the
screenbox. Check the safety switch to the hopper by starting the granulator. It
should not be possible to start the granulator until the hopper is lowered and the
break screws are screwed in.
