extent that the end chain link of the idle chain is
not released from the hoist body. In versions with
chain box, the idle chain is not attached to the hoist
body.
Note:
For assembly, it is helpful to fasten a short
assembly chain
5
to the end of the chain by means of
an open chain link
6
before pulling the chain out of
the bottom block. This assembly is pulled into the bot-
tom block as the chain is pulled out and remains there
until assembly is completed.
Pull out the chain from the bottom block. The buffer
7
and buffer discs
8
are thereby pulled from the chain.
Assembly
Push the buffer discs (edge encloses buffer) and the
buffer onto the chain.
Align the chain and fasten it to the assembly chain
in the bottom block by means of the open chain link.
Pull the chain through the bottom block and detach
the assembly chain and the open chain link from the
chain.
If no assembly chain has been used, the end of the
chain must be inserted into the bottom block and
pulled through by turning the sprocket wheel using
an auxiliary tool.
If the chain link pin was not completely pulled out,
only align the bottom block chain and push the
chain link pin through the chain link to be attached
(position of the weld must align with that of the fol-
lowing links).
If the chain link pin was pulled out completely, align
the bottom block chain and the idle chain and push
the chain link pin into the hoist. It must first be
guided through the end link of the idle chain and
then through the end link of the bottom block chain
(position of the weld must align with that of the fol-
lowing links).
Drive in a new roll pin to secure the end link pin.

Removal
Move the bottom block as close as possible to the
hoist body. Position the bottom block securely in
order to prevent the chain from unravelling uncon-
trollably causing the bottom block to fall.
Remove the chain link
1
from the chain mount on
the bottom block; drive out the roll pin
2
and the
end chain link pin
3
for this purpose.
Note
: For assembly, it is helpful to work with two short
assembly chains
4
which are fastened by means of an
open chain link
5
to the hoist chain being pulled out
during removal of the chain and are pulled successively
over the deflection sprocket of the centre section and
the bottom block. They remain there until assembly is
completed.
