Troubleshooting 

1. 

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 qualification. 

•

 

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’.
