Lubrication instructions for the chain
Initial lubrication of the chain
For cleaner installation routines, the hoist is delivered with an
unlubricated
chain. Even if the chain feels oily, it is
not lubricated, but bears only a corrosion protection. The initial lubrication is included in the commissioning
preparations of a new hoist.
WARNING
Failing to do the initial lubrication of the chain leads to premature wear of the
chain and other components of the chain drive. Without the initial lubrication,
the lifetime of the chain and the complete chain drive is reduced drastically. As
a result, the chain can fail. The wearing starts immediately after taking the
hoist into use.
Lubricate the chain carefully before taking the hoist into use for the first time.
Lubricating the chain
The target of the chain lubrication is to have enough lubricant
between the chain links
. The lubricant (grease or
oil) must be applied on the
contact surfaces
between the chain links. Make sure that you add the new layer of
lubrication always on a clean surface. Lubricate the chain without any load attached to the hoist.
To lubricate the chain:
Drive the hook all the way down until the chain is completely out of the chain bag and the chain bag is empty. If
there is a load attached to the hook, remove the load.
Start applying the lubricant on the chain from the top, close to the hoist. Position the grease tube or oil bottle at
the output of the chain guide and lubricate the chain, proceeding from top to bottom, while driving the hook up
at low speed.
When you have completed the lubrication, drive the hook up and down three to four times over the full length of
the chain without any load attached to the hook. The lubricant spreads evenly throughout the chain.
