SERVICE BRAKE & PARK BRAKE 
ADJUSTMENT 
Brakes are critical to the safe operation of the machine. 
Check the function of the brakes frequently. Refer to 
Section “Maintenance – Check Brakes”. If adjustment is 
required, complete each of the following steps carefully. 
Always verify that the brakes function properly after 
performing any brake adjustments. Do Not operate the 
machine if the brakes are not functioning properly. 
 
WARNING 
DO NOT operate machine if brakes are not 
functioning properly.  Adjust, repair or replace as 
necessary.  Contact your local authorized dealer for 
assistance. 
 
1.  Park machine on flat surface. Set park brake. 
Remove key. 
2.  Locate left and right brake adjustment nuts. 
Clearly mark the nuts so that you will be able to 
count turns.  See Figure 4.2. 
 
 
 
FIGURE 4.2 (Seen from above) 
 
3.  Using a 7/8” deep well socket, turn each nut one-
half turn clockwise, tightening brake adjustment. 
4.  Check function of brake. Refer to Section 
“Maintenance – Check Brakes”.  
5.  If additional adjustment is required, turn each nut 
one-half turn clockwise and re-check brake 
function. 
6.  Repeat until brakes function properly. DO NOT 
exceed two turns total and only make 
adjustment in half-turn increments. Over-
tightening the brakes will lead to premature 
wear and brake failure. Contact local 
authorized dealer for assistance. 
7.  After completing the brake adjustment and 
verifying that they function properly, further fine 
adjustment may be required to balance the action 
of the left and right brakes.
