• Remove load hook from the old load chain and suspend open load chain link in the loose
end of the load chain.
• Suspend the new, lubricated load chain also in the open link and pull it through the hoist unit
(turn hand wheel clockwise).
• Do not fit a twisted chain. The welds must face outwards from the chain wheel.
• When the old load chain has passed through the hoist unit it can be detached together with
the open chain link and the load hook can be fitted on the new load chain just pulled in.
• Detach the chain stop from the loose end of the old, replaced load chain and fit it to the loose
end of the new load chain just pulled in.
ATTENTION: The chain stop must always be fitted to the loose end of the chain (idle
fall).
Hoist with single fall (model C85 - roller chain)
• Remove load hook from the old load chain.
• Activate chain release by turning the selector lever on the handle.
• Pull the old load chain to be replaced through the hoist unit by turning the hand wheel
clockwise (LIFTING chain movement) and dispose of it.
NOTE: The chain outlet opening on the underside of the unit, which is precisely in the
extension line of the top hook, always is the loaded-fall side, on which the load hook
must be fitted.
• Guide the new, lubricated load chain with the open end into the chain opening out of which
the old load chain was pulled and while doing so turn the hand wheel counter-clockwise
(LOWERING chain movement). The roller chain is then caught by the chain wheel and
transported through the hoist unit.
• When the new roller chain has passed through the hoist unit, the load hook can be fitted
again.
Hoist with several falls (model D85 - round-section steel chain)
ATTENTION: Only pull in the new chain when the bottom block is unloaded, otherwise
the bottom block may drop when the load chain is detached. Danger of injury!
• An open load chain link is required as a tool. It can be obtained by using an abrasive wheel
to cut a section from an existing link with the same dimension. The length of the cut section
must at least correspond to the thickness of the link.
• Detach the loaded-fall end of the load chain from the housing of the hoist unit or the bottom
block (depending on model).
• Suspend prepared, open load chain link in the now free load chain end.
• Suspend the new, lubricated load chain also in the open link and pull it through the bottom
block and the hoist unit (turn hand wheel clockwise).
• Do not fit a twisted chain. The welds must face outwards from the chain wheel.
• When the old load chain has passed through the hoist unit it can be detached together with
the open chain link.
• Fix the loaded-fall end of the new load chain on the housing/frame or on the bottom block
(depending on model) of the hoist.
• Attach the chain stop to the loose end of the new load chain.
ATTENTION: The loose end of the idle fall must always be fitted to the chain stop (Fig.
1).
