6.1 Starting and stopping
The main switch is located beneath the control panel
on the front of the granulator.
Starting and stopping is controlled by push buttons
on the control panel.
NOTE! Never stop the granulator before all material in
the hopper and cutter housing is completely granulated.
Residual material will clog the rotor in the granulator
during re-start. The motor will be overloaded and the
overloading protection will trigger.
6.2 Inspection
There must be no plastic material left in the granulator
when inspection is carried out.
NOTE! 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 damaged
flaps at once. Damaged flaps can drop down into the cutter housing and dam-
age 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 (anticlockwise).
