13. Adjusting 

brake 

 WARNING 

  Check if the brake is effective or not one-sided. An 

accident can result.  

 
  Unbalanced play at left and right brake pedals can 

cause one-sided braking effect. Keep the same 
amount of play; otherwise, an accident can result.  

 
Depress the brake to see a required play of 30-40 mm is 
available and if the left and right pedals work together. If 
not, adjust the turnbuckles behind the pedals for a play 
of 30 mm. Secure the turnbuckle with the lock nuts. 
Make sure the parking brake lock is put on when the 
brake pedals are fully stepped in.  
 

(A) Play 30-40 mm
