-Take the conveyor belt out of the machine and rest it on trestles (set out along its entire length) turning it through
180° in relation to the position in the machine.
- Remove chips scraper ‘A’ using the 2 fixing screws, the 4 bottom guide rollers ‘B’ using the relative fixing screws
and the spacer ‘C’ with the relative guide walls ‘D’ using the fixing screws (Fig. 10-23) .
- Turn the 4 adjusters ‘E’ (2 for each end of the belt) fully home (inwards) undoing the fixing screws ‘E1’ , then
turn inwards the relative belt support plates ‘F’ by undoing fixing screw (Fig. 10-24) .
- In this way the tension has been slackened off the belt which can now be removed by pulling it out carefully.
- Remove the screw adjusters for the belt and fit them into the new one (if the old one is being replaced)
- Fit the new belt (or the same one once it has been cleaned) making sure the space between the 2 sides is
roughly equal ( N.B. The belt has an arrow that shows the direction of rotation - see Fig. 10-25 ).
- Fit chips scraper ‘A’ using the 2 fixing screws, the 4 bottom guide rollers ‘B’ using the relative fixing screws
and spacer ‘C’ with the relative guide walls ‘D’ using the fixing screws ( Fig. 10-23 ).
- To tension the belt, turn the 4 belt support plates ‘F’ outwards, then bring the 4 adjusters ‘E’ up to the relative
plates using the 2 fixing screws ‘E1’ ( Fig. 10-25 ).
N.B. To tension the belt correctly, it is best to move it with a “makeshift” connection to the motor cables (an
“expert” electrician should be used).
- “Fine” tensioning is done using the 4 screws that fix the support plates as shown in Fig. 10-26 .
- As well as the belt being tensioned correctly, to make sure it is also centred (away from the sides), turn screw
adjuster ‘G’ (Fig. 10-27) .
- Once the belt has been tensioned and centred correctly, tighten all the fixing screws, adjusters and support
plates, then the “makeshift” connection to the motor cables can be eliminated.
- The conveyor belt can now be fitted to the base of the machine following the dismantling operations in reverse
order.
- Unlock the pneumatic master switch and turn it to “I” then turn the main switch to “I” .
- Carry out a few test runs (especially to make sure the direction of rotation is correct).
