Hose rupture valves
(optional equipment)
WARNING
Risk of crushing by falling attachments.
Hydraulic or mechanical failure could cause the
attachments to fall, resulting in severe personal
injury or death.
Ensure no persons can enter the danger zone until
the failure is resolved.
If the machine is equipped with a hose rupture
valves, it will reduce the falling speed of the boom
if a hose bursts.
Lowering the boom with hose rupture protection
In case of standstill or engine defect and power
failure during loading operation, the accumulator
pressure is sufficient to lower the attachment to the
ground with the control levers.
NOTE!
Too low pressure in the accumulator may make it
impossible to lower the attachment.
Blade float position
NOTE!
The blade float position has no function in
combination with hose rupture valve on blade.
