Safety is important in connection with all repair work on the MAXI-
DISC. The following safety precautions and the precautions listed in 
the beginning of this manual must be observed. 

 

 

Before performing any adjustments, maintenance or repairs on 
the  machinery, always  unfold the  MAXIDISC and  lower  the  im-
plement to the ground or secure in transport position, set the 
tractor brakes, turn off the engine and remove the ignition key 
to avoid unintentional operation. 

 

 

Pay careful attention to safety when performing repair work on 
the hydraulic  system.  Remove  hydraulic  pressure prior  to do-
ing any maintenance.  

 

 

After making repairs to the hydraulic system, always bleed air 
out of the system before operating the MAXIDISC again to avoid 
any possible personal injury or mechanical breakdown or dam-
age.
