and bolts, particularly on fixing elements (tines, forks,
blades, knives, etc). Retighten if necessary.
Before operating the machine, ensure that all the safety
guards are firmly in place and in good condition.
Immediately replace any worn or damaged guard.
Precautions when driving
Tractor handling, stability, performance and braking
efficiency are all affected by weight distribution, trailedor
mounted implements, additional ballast and driving
conditions. It is therefore of great importance that the
operator exercises caution in every given situation.
Groundspeed must be adapted to ground conditions as
well as to roads and paths. Always avoid abrupt changes
of direction.
Be particularly cautious when turning corners, paying
attention to machine overhang, length, height and
weight.
Never use a narrow track tractor on very uneven or
steeply sloping ground.
Never leave the tractor seat while the machine is
operating.
Carrying people or animals on the machine when
working or in transport is strictly forbidden.
