Lifting
Malfunctions in lifting mode
Incorrect extension sequence
DANGER
Risk of accident!
With triple lift masts (variant), an incorrect extension
sequence may occur, i.e. the inner lift mast may
extend before the free lift has finished. As a result,
the overall height is exceeded and damage can
be caused when passing through entrances or in
areas with low ceilings.
An incorrect extension sequence can be
caused by the following:
• The hydraulic oil temperature is too low
• The fork carriage is blocked in the inner lift
mast
• The free lift cylinder is blocked
• The chain roller for the free lift cylinder is
blocked
– 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 be caused by the following:
• The fork carriage or the load is resting on
the racking
• The fork carriage rollers are 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
lower the load at another suitable location.
