An incorrect extension sequence may, for in-
stance, result from:
●
The hydraulic oil temperature being too low.
●
The fork carriage becoming blocked in the
inner lift mast.
●
Blocking of the free lift cylinder.
●
The chain roller becoming blocked at the
free lift cylinder.
– If the hydraulic oil temperature is too low,
slowly actuate the lift mast functions several
times in order to raise the oil temperature.
In the event that the fork carriage is blocked in
the inner lift mast, or the free lift cylinder or
chain roller are blocked, the cause of the
blockage must be eliminated before resuming
work.
– Notify your service centre
Load chains not under tension
DANGER
Danger caused by a falling load!
– Make sure that the chain(s) does (do) not become
slack when lowering the load.
Slack chains can, for instance, result from:
●
Resting the fork carriage or the load on the
racking.
●
Fork carriage rollers becoming blocked in
the lift mast due to contamination.
– If the fork carriage or the load comes to an
unexpected stop, lift the fork carriage until
the chains are under tension again and low-
er the load at another suitable location.
– If the fork carriage rollers in the lift mast be-
come blocked due to contamination, lift the
fork carriage until the chains are under ten-
sion again. Remove the contamination be-
fore resuming work.
WARNING
Risk of injury!
– Observe the safety regulations for working on lift
masts; see
