Operation
Emergency operation
Securing the load support
In order to secure the load support against
lowering during maintenance work, the
lowering movement can be locked by closing
the shut-off valves. A notch in the block
section indicates the valve position.
• The notch is pointing in the direction of the
connected line = flow open
• The notch is at a right angle to the direction
of the connected line = flow blocked
DANGER
Risk from lowering of the lift mast or driver's cab
– The pressure in the hydraulic system must be
released before any work is carried out on it. The
load support must also be lowered to the ground.
– Before a person can go underneath the raised
driver's cab, an additional mechanical safety
device must be installed. For example, fit a
suitably strong brace around the bridge pieces
on parts of the lift mast or place a suitably strong
jack stand underneath the driver’s cab.
– Lock all existing shut-off valves. There is a valve
for each main lift cylinder (1), one for each free
lift cylinder* (2) and two additional valves for the
hydraulic lines for the attachment (3).
*Option
Emergency operation
If the entire truck control unit or part of it
fails, the industrial truck can be moved out
of the working area by means of the relevant
emergency operation mechanism.
WARNING
– Only tow at creep speed
– There must always be an operator in the indust-
rial truck that is being towed.
– There must not be anyone in the danger area of
the trailer train.
– In order to prevent strong lateral forces and
therefore the risk of tipping, always leave plenty
of space when driving round corners.
– The vehicle used for towing must always be
driven carefully and be able to brake gently and
in good time.
