ISSUE
REASON
CORRECTIVE ACTION
Outrigger gives in.
Make sure that the ground
doesn’t give in.
Air in outrigger cylinder(s).
Dirt in load check valve or
defective valve.
Faulty outrigger cylinder seals.
Put extra support plates under
the outriggers or move the
machine to another place.
Drive outriggers up and down a
couple of times.
Clean valve with compressed
air, if that doesn’t help change
valve.
Change cylinder seals.
Platform tilts backward by itself
when booms are down on
transport supports.
Air in hydraulic system.
Dirt in load control valve or
defective valve.
Cylinder seals faulty.
Start the combustion engine /
electric motor, drive the platform
to extreme end positions. If this
doesn’t help, do the air bleeding
of the platform self levelling
system (there are bleeding
screws in the self levelling
cylinders).
Clean valve with compressed
air, if that doesn’t help change
valve.
Change cylinder seals.
Automatic leveling does not
work, the access platform will
level the chassis but booms are
not operational. The green light
does not blink.
One of the four outriggers is not
firmly against ground or the
outrigger limit switch is
defective.
Ensure all outriggers are
properly deployed, check
outrigger sensors (see 9.8).
Automatic leveling does not
work, the access platform will
level the chassis but booms are
not operational. The green light
is blinking.
The chassis is not levelled,
issue with the levelling sensor
on the chassis.
Re-level the access platform,
check level sensor.
All outriggers firmly against
ground. The green light does
not blink and the fault light
blinks.
Issue with the automatic
leveling.
Drive outriggers off the ground,
re-level, check outrigger sensors
if necessary (see 9.8).
Booms on their transport
supports, the green transport
support light is not on and the
fault light is blinking. Outriggers
will not operate.
Issue with outrigger sensor.
Ensure all outriggers are
properly deployed, check
outrigger sensors (see 9.8).
