13.1 Optional extras
13.1.1 Description (Chapter 4)
13.1.1.1 Pipe Burst Protection
A pipe burst protection valve is fitted at the ground side of
lifting and tilting cylinders. In case of rod or pipe burst in the
lifting or lifting/tilting subsystem, any movement of the
loader arm or tilting mechanism is interrupted until the
problem is solved.
ATTENTION
Activating loader arm cushioning disables the
pipe burst protection mechanism.
13.1.1.2 Lift Limiter
A device mounted at the joint between the bucket assembly
and the swivel assembly allows you to limit the maximum
lifting height.
Setup:
(1) Lift the loader arm to the required height.
(2) Switch off the engine and close the stop valves for
main and auxiliary hydraulics (1-2/arrows).
(3) Loosen the hexagonal bolts (SW 10) (13-1/3) on the
gear gate assembly and rotate the gate (13-1/2) against
the roller gage (13-1/1) until you hear the gate shift.
(4) Re-tighten the hexagonal bolts on the gear gate
assembly.
DANGER
Perform a functional check before starting a job
that requires the lift limiter, and while working
perform a visual check while seated in the driver´s
seat.
