Retensioning the chains / Replacing the test rollers

Check chain slack: It should be possible to move the chain up and down by hand by
approx. 5 mm. If the chain is too lightly tensioned, proceed as follows:

Loosen the fastening screws of the pedestal bearings on both sides.

Adjust the chain to the correct tension using the adjusting screw.

Move the roller(s) in parallel, not one-sided.

Retighten the fastening screws (tightening torques: see table).

NOTICE

It is recommended by the manufacturer that the fastening screws be replaced each
time an adjustment is made.

Use a "medium strength" threadlocker.

Recheck chain tension.
