Faults and their remedy
Observe the safety instructions!
If faults occur in the tractor or the engine that require a greater degree of intervention, al-
ways have them rectified at your
specialist workshop, since they have the necessary
tools. Unprofessional intervention can only cause damage.
In order to avoid damage to the machine and life-threatening injuries when rectifying faults on
the machine, it is essential to pay attention to the following points:
•
Rectify faults only if you are in possession of the specified qualifications.
•
First of all, secure the machine against inadvertent rolling away by chocking the wheels.
•
Secure the range of action of the moving machine parts.
•
Also read the chapter ‘General safety instructions’.
