Check the chain guides for wear and when the following
wear dimensions are reached with regard to chain guide
diameters or hook mounts in the centre section of the
device: Replace the housing:
The wear dimension must be measured at the points
on the guide surfaces which have been worn down by
the chain.
See check dimensions, page 49.
Maintenance and lubrication
Please ensure that load hooks and/or load eye mounts
are regularly checked and lubricated, at least once
annually.
Especially important: in areas where wear-
promoting conditions such as high ambient temperatures
or corrosive substances in the atmosphere are present,
or where lubricants may be washed out,
the frequency
of maintenance and inspection intervals must
always be increased.

In the event of insufficient maintenance/
lubrication the extent of wear may be so
high that there is a danger of loads falling.
P R E V E N T I O N O F DA N G E R S
Dangers are avoided by regular maintenance/lubrication
in suitable intervals.
