Checking the condition of the
wheels
–
Raise the truck until the wheels are off the
ground.
–
Check that the wheels rotate freely and re-
move any objects that may prevent them
from turning or may obstruct them.
CAUTION
Risk of damaging the wheels
In order to avoid any risk of damaging the bearings
and tyres of the wheels, it is essential to remove any
wires or plastic strips that may wind around the
wheel hubs and mountings.

Stabiliser maintenance
Trucks are equipped with two stabilisers. They
ensure the dynamic stability of the truck. Dif-
ferent types of stabilisers are available as op-
tions.
Stabilisers do not require any specific mainte-
nance or adjustment work. Wheel wear (drive
wheel and stabiliser wheel) is automatically
compensated.
However, it is necessary to check the condi-
tion of the stabilisers:
●
No significant damage to the superstruc-
ture.
●
The damper cylinder pins must not be twis-
ted.
●
No oil leakage must be present on the
damper cylinder. This cylinder must be in-
side the spiral spring.
●
No damage to the rollers. The wheels must
rotate freely
●
No locking at the level of the upper bearing.
●
Ensure that the wheel nuts are correctly
tightened.
●
Ensure that there is no oil leakage under
the truck when it is fitted with hydraulic sta-
bilisers.
WARNING
Risk of loss of dynamic stability
The dynamic behaviour of the device must be moni-
tored, particularly when turning. The behaviour of the
truck must be the same when cornering, whether
turning to the left or right. If there is a difference in
behaviour, please contact the After-Sales Service
Centre. Only the technician can replace the two sta-
bilisers if deemed necessary.
NOTE
It is necessary to monitor the wear of the
wheels in order to preserve the traction of the
truck.
