Operation and Daily Maintenance
Inspection
There must be no plastic material left in the granulator when
inspection is carried out.
CAUTION: All servicing must be done by trained personnel in order to avoid personal
injury and damage to the machine.
Daily Inspection
Flaps in the hopper. Check that the flaps are undamaged. Replace dam-
aged flaps at once. Damaged flaps can drop down into the cutter housing
and damage the knives. Damaged flaps also entail the risk of material
ejection.
Emergency stop. Check the emergency stop function. Start the granulator
and stop it with the emergency stop(s).
Reset. Turn the stop button in the direction of the arrow (counterclock-
wise).
Weekly Inspection
Cables. Check the electric cables of the machine for wear or other dam-
age. Replace damaged cables at once.
Safety switches. Check the safety switch functions.
This granulator has 2 safety switches:
1 at the hopper
1 at the screen box
Check the hopper´s safety switch.
Undo the star knobs on the hopper, and try to start the granulator.
The granulator should not be possible to start before the hopper has been
closed and the star knobs are properly tightened to stop.
Check the screen box safety switch.

The granulator should not be possible to start before the screen box has
been closed and the star knobs are properly tightened to stop.
