Replace the drive chain after 15,000 hours (see page 45).

– the sprockets for wear.



Replace the sprockets if you see visible wear.

– the support block and support rails for wear.



Replace the support block and support rails after 15,000 hours.

– the cleat (hook) for wear (see page 48).



Replace the cleat (hook) if the workpiece pallet is no longer fed in or out
correctly (see page 44).

– the damping element for wear (see page 44).



Replace the damping element if the wear is > 3 mm.

– whether the bolt spring is fractured (see page 44).



Replace the bolt spring if the hook does not reset correctly (see page 44).
