Checking the Condition of the Cutters

WARNING! Danger of cutting caused by sharp cutters at all times—even when rotor is at standstill. Serious Injury especially to the hands and fingers can occur. Wear protective gloves!

The cutting cutters become blunt after a certain number of operation hours; they should be checked regularly. Using blunt cutters can affect the efficiency and performance of the machine in the following ways:

•Decreased shredding capacity.

•Increased current consumption of the drive motor.

•Inexact cut.

•Overheating of the shredded material.

Dismounting the Cutters (see drawing below)

1.Switch OFF the shredder at the main switch.

2.Safeguard main switch using a padlock.

3.Open the machine door.

4.Safeguard the machine door.

5.Remove screen.

NOTE: Although it is possible to reach the cutting shaft by climbing into the feeding chamber, it is recommended to access the cutters through the machine door located at the front of the machine. The shaft can be rotated manually by turning the motor v-belt pulley.

6.Clean the hexagon head socket of the cutter mounting screw (2).

7.Loosen the screw using a high quality Allen key (10 mm). Knock the Allen key lightly with a hammer to loosen it if necessary.

8.Take out the cutter mounting screw, the washer, and the cutter.
