1. Safety precautions
Front linkage
Front loader
Differential lock
Use the differential lock only when running on loose or slippery ground.
Overturning
Hydraulic/fuel pressure
Do not attempt to locate a leak in the hydraulic system or attempt to close a
leak using any part of your body.
WARNING: When the front linkage is being connected to the rear
valve, make sure there is no load on the front linkage or rear
implement connected to the same valve. The load on the front
linkage or rear valve implement discharges when the shut-off
valve lever is turned. This may cause the implements to move
abruptly.
WARNING: When you drive on public roads and there is no
implement on the front linkage, the lifting links have to be folded
up.
WARNING: To prevent involuntary loader motion, the loader
joystick controller must be of the self-neutralising type. When the
operator releases their grip on the joystick, the joystick must return
to the neutral position, except for the float detent position in the
loader lowering direction.
WARNING: The risk of overturning increases as the loader is
raised. Be extra careful on slopes when operating the loader.
Always carry the load as low as practical for the conditions.
Always consider the way in which the tractor is to be used and the fact
that the centre of gravity of the tractor/implement assembly changes
according to the load being transported or towed.
Adapt the tractor speed according to visibility, weather conditions and the
type of terrain.
Do not transport loads in the top position. Transport them as low as
possible and balance the tractor with ballast weights.
Do not accelerate, brake, turn or release clutch too suddenly when
driving on a slope.
If possible, drive so that the heavier end of the tractor is towards the top
of the slope.
Work situations with an increased risk of overturning include front-loader
work, lifting of heavy loads with the rear or front linkage, forest work,
especially with a boom, as well as driving on a soft, uneven or inclined
surface.
WARNING: The instructions concerning overturning in this manual
are not exhaustive.
CAUTION: Oil/fuel under high pressure easily penetrates clothing
and skin and can cause serious injuries.
