3.2.1 REPLACEMENT OF PADS ON CONVEYOR CHAIN
CAUTION!
Always put the machine into a condition of safety before accessing moving parts. You are reminded that all
maintenance operations on the machine and on tools must be carried out only by a specialized operator, and
that work gloves, clothing and footwear complying with work safety requirements must be worn.
To replace the rubber pads on the feed chain, the following tool is required:
- Flat-head screwdriver
Referring to Fig. 3.13e, proceed as follows:
1)
Remove the panel exit plate.
2) Move the pad to be replaced close to the motor pinion gear.
3) Use the screwdriver to gently raise the pad to be replaced.
4) Check that the new pad has the rounded prole facing outwards, in the same direction as the other
pads. The new pad must be preheated at a temperature of at least 25°C to avoid breakages.
5) Fit the new pads moving the feed chain forward manually, ensuring that the holes t correctly over the
xing pins. The correct position is conrmed by the sound of a click.
6) Replace the panel exit plate and check that it does not come into contact with the rubber pads.
