PRECAUTIONS FOR OPERATION

PRECAUTIONS WHEN TRAVELLING
When travelling over obstacles such as boulders or tree stumps,
ensure sufficient clearance to avoid undercarriage damage. As
far as possible, remove such obstacles or avoid travelling over
them.
Do not operate machine (working or travelling) on 1 tyre (if twin
tyres are fitted) after a puncture as this puts excessive load onto
the one remaining tyre.
To prevent loss of control refrain from travelling fast over rough
ground.
