ISSUE

CAUSE

CORRECTIVE ACTION

Outrigger gives way.

Make sure that the ground does
not give way.

Air in the outrigger cylinder(s).

Dirt in the cylinders lock valve.

Faulty lock valve.

Faulty outrigger cylinder seals.

Put extra support plates under
the outriggers or move the
machine to another place

Drive outriggers all the way up
and down a few of times.

Clean the valve with
compressed air.

Change the valve.

Change the cylinder seals.

The platform tilts backwards by
itself when the booms are down
on the transport supports.

Air in the hydraulic system.

Dirt in the load control valve or
a defective valve.

Cylinder seals faulty.

Start the combustion engine /
electric motor, drive the
platform to the extreme end

positions. If this doesn’t help, do

the air bleeding of the platform
self-levelling system (the self-
levelling cylinders are equipped
with couplings for bleeding
purposes)

Clean the valve with
compressed air, if that does not
help, change the valve.

Change the cylinder seals.
