Still 6219, Original Instructions Manual

Page: 270 / 540

Reversible fork arms (1) can be used to reach
an additional lift height. The reversible fork
arms are attached to the fork carriage in the
same manner as standard fork arms. Loads
may be lifted on and beneath the reversible
fork arms. The mast is lifted and tilted in the
same manner.
–
Only work in reverse operation using rever-
sible fork arms.
–
Do not use a fork extension (variant).
–
If the "load measurement" comfort feature
(variant) is available, perform a "zero ad-
justment of the load measurement".
–
To drive, raise the load centre of gravity (2)
to a max. of 600 mm above the ground.
–
Observe the information in the section enti-
tled "Transporting suspended loads".
Malfunctions during lifting mode
Incorrect extension sequence
DANGER
Risk of accidents!
In the case of Hi-Lo lift masts (variant) and triplex lift
masts (variant), an incorrect extension sequence
may occur, i.e. the inner lift mast may extend before
the free lift is complete. As a result, the overall height
is exceeded and damage may occur in passageways
or from low ceilings.
An incorrect extension sequence may, for in-
stance, result from:
●
The hydraulic oil temperature being too low.
●
Blocking of the fork carriage in the inner lift
mast.
●
Blocking of the free lift cylinder.
●
Blocking of the chain roller on 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.
