breaker will trip.
Check the knives. Sharpen or replace the knives, or adjust the knife clearance,
see next section.
• If the granulator is equipped with a speed monitor and the cutter speed falls too
low during granulating, the speed monitor will trip.
Ensure that the drive belts are not slipping.
The speed monitor has no reset.
Clean and restart the granulator.
• If the drive belts tension not is enough, the transmission will slip and the
granulator motor overload protection trips.
Check and adjust the drive belt tension. see section 7.3 “Transmission”
• At a bad or loose contact in connection to a safety switch/limit switch, the
granulator will stop.
Call for an qualified electrician for fault-finding and appropriate measures.

The granulator cutter must stop, before the cutter house door can be opened.
The granulator has a standstill monitor which senses inductively, when the
cutter has stopped.
The standstill monitor locks the breaking key to the locking device on cutter
house door, so long time as the cutter is in motion.
An indication lamp in the knob “Hopper operate I” on electrical cabinet and a
green diode lamp on the safety switch lights, when the locking of the breaking
key in the safety switch opens.
