Machine maintenance
The machine must be disconnected from its power source before any maintenance, adjustment, replacement
or cleaning measures. Only use spare parts that are supplied by the manufacturer or your retailer. If the
guards of the machine have to be removed for maintenance, they must always be reattached before the
machine is activated. After maintenance and adjustment measures, a test run must be carried out on the
machine, according to the instructions in
5.1.
Chains
Tighten the chains of chain conveyor A in accordance with
Figure 4
. Adjust them by opening the tensioning
nut as shown in Figure 4 on the
left
. The figure on the
right
shows the tightened tensioning nut after
adjustment. The tightness is correct when the chain hangs in the housing about 10 mm from the bottom and
rises about 100 mm when lifted from the centre. Excessively tight chains move sluggishly and excessively
loose chains increase wear or cause jams.
Figure 4 (Adjusting the tightness of the chain conveyor’s chains)
Tighten the motor chain by opening the motor guard of chain conveyor A. The correct tightness is presented
in Figure 5 to the left. Tension the chain as follows:
Open the three motor fastening screws in Figure 5 (pictured in the centre).
Open locking nut B, tighten bolt A and finally lock the locking nut and tighten the motor’s
fastening screws (in the middle).
