6.5.2 Fitting the retainers and compression springs
The retainers and compression springs should be fitted back in the reverse sequence of operations.
NOTE
Before fitting the compression springs check their length. When unloaded they should be 32 mm. If this is not
the case change the springs, always doing so in pairs for each side of the conveyor.
● Align the guide rails as described in Section 6.6, Page 6 - 29.
6.5.3 Function test
Under the Conveyor functions menu carry out a function test with the boards.
