Precautions to take before using the

machine

Do not wear loose clothing which could become caught

up in moving parts.

Wear the appropriate protective clothing for the work in

hand (gloves, shoes, goggles, helmet, ear defenders,

etc.).

etc) are placed so as they cannot be operated

unintentionally and cause damage or injury.

and bolts, particularly on fixing elements (tines, forks,

blades, knives, etc). Retighten if necessary.

guards are firmly in place and in good condition.

Immediately replace any worn or damaged guard.

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
