SETUP AND ADJUSTMENTS
Park Brake Adjustment
When park brake is in the engaged position the distance between the trunion and the bolt head at the rear of the assembly should measure 1/8” to 1/4” and the spring should measure 1.25”. To adjust the gap between the trunion and the bolt head loosen the nut against the yoke then turn the bolt head the proper direction to achieve the proper gap. To adjust the length of the spring turn the nut against the spring the proper direc- tion to lengthen or shorten the spring. This adjustment is the same for both sides. FIG - 8
•If brake lever trys to catch as you engage the brake the spring needs to be tightened. When you change the spring length you also have to maintain the 1/8” to 1/4” gap between the bolt
head and the trunion.
NOTE: Do not force the brake lever into the on position if it is catching this will cause damage to the brake assembly.
•If brake squeaks while the machine is in use. The spring may be to tight or the gap between the bolt head and the trunion may be to large.
Motion Control Linkage Adjustment
This adjustment must be made with the rear wheels rotating. Raise the rear of the machine and block it up so the wheels are free to rotate.
CAUTION: Keep hands, feet and clothing away from rotating tires.
