7.9 Assembly and disassembly of the brake-clutch assembly group
The brake-clutch assembly group is a separate fully closed assembly group.
Caution!
All assembly and disassembly works have to be done without load.
The electric chain hoist has to be switched off and disconnected from the grid.
Before disassembly the electric chain hoist must be suspended in normal use (upright use)
or supported horizontally.
Risk of oil loss.

7.10 Load chain
Hoist chains are means of load carrying which require official approval. It is, therefore, important to observe the
guidelines issued by the Institution for Statutory Insurance and Prevention with regard to round steel chains in
hoisting operation, the guidelines for general inspection and test specifications in accordance with DIN 685-5:1981,
DIN EN 818-7:2002+A1:2008 and the accident prevention regulations in DGUV V54 (BGV D8) and in DGUV V52
(BGV D6) or equivalent regulations in the respective country.
7.10.1 Lubrication of the load chain before initial operation and during operation
The links along the entire length of the load chain must be lubricated with penetrating gear lubricant oil
before starting operation for the first time and during operation. The chain has to be lubricated with no load
in order to get the lubricant in the contact areas between the chain links. Subsequent lubrication, whereby
the links must be cleaned first, depends on the frequency of use and the operating conditions.
A dry-film lubricant, e.g. lubricating varnish, graphite powder, should be used when ambient influences
are conducive to wear (sand, emery).
