Clean the granulator from anticorrosive agent.
Unpainted parts of the machine are treated with oil as protection prior to trans-
portation and delivery. Clean the granulator from anticorrosive agent.
Remove the anticorrosive agent using low-aromatic White spirit or cold degreasing
agent. Then wipe dry and clean with lintless rag.
Check before the first start
•
Ensure that the cutter housing is accurately in horizontal level.
IMPORTANT! Ensure that all of the machine shoes carry load.
•
Ensure that at least one emergency stop knob is always within reach of the
operator inside the working range of the granulator, including optional
equipment for the granulator such as belt conveyor, shredder, dust filter, etc.
•
Check tightening torque of screws to the knives.
Check tightening torque to the fixed knives:
– rear (no. 1), front (no. 2) and possibly third fixed knife . . . . . . . . 600 Nm
– fourth and fifth fixed knife . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 600 Nm
Check tightening torque to the rotating knives:
– granulator with 3-blade cutter . . . . . . . . . . . . . . . . . . . . . . . . . . . . 600 Nm
– granulator with 5-blade cutter . . . . . . . . . . . . . . . . . . . . . . . . . . . . 600 Nm
To check the knife clearance and tightening torque, read section 7.1 “Knife
changing”.
• Check the knife clearance using a feeler gauge, check in the middle of the
cutter housing and in the outer ends of the knives, the knife clearance must be
0.20 - 0.50 mm.

1
Check the tightening torque of all screws which are holding the granulator knives.
First check the screws which are holding the fixed knives.
Then check the screws which are holding the rotating knives.
2
Check the knife clearance between all rotating knives in the granulator against
the rear and the front fixed knives (fixed knife no. 1 and fixed knife no. 2).
The knife clearance must be 0.20 - 0.50 mm.
3
Check the screws which hold the granulator motor to the motor mounting bracket.
