Operation 4
Lifting
An incorrect extension sequence may, for
instance, result from:
• The hydraulic oil temperature being too low.
• Blocking of the fork carriage i
n the inner lift
mast.
• Blocking of the free lift cylinder.
• Blocking of the chain roller on the free lift
cylinder.
– If the hydraulic oil tempera
ture is too low,
slowly actuate the lift mast
functions several
times in order to raise the oi
l 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 blocking 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
lower the load at another suitable location.
– If the fork carriage rollers in the lift mast
become blocked due to contamination, lift
the fork carriage until the chains are under
tension again. Remove the contamination
before resuming work.
WARNING
Risk of injury!
– Observe the safety regulations for working on
the lift mast, see the chapter entitled "Working at
the front of the truck".
