1.Stop engine and remove key, release park brake and check the gap between the rear tire and the brake arm. The gap should be 1/8” to 1/4”.
2.If adjustment is needed, loosen the lock nut next to the yoke. Remove the pin from the front yoke so you can rotate the yoke on the adjust- ment link until the proper gap is achieved.
3.Make sure the brake arm on both sides does not touch the tire when the brake is in the off position. FIG - 5

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.
Tilt seat forward and remove the seat rod so the seat may rotate forward onto the frame.
Place a 2x4 board between the foot plate and the center of the seat to engage the seat safety switch.
Loosen the nuts directly behind each ball joint on both rods that connect the pump arm to the mo- tion control assemblies. FIG - 6
Start the engine. The park brake must be engaged and the motion control levers in the neutral slots to start the engine. Run the engine approximately half throttle
Release park brake to allow the wheels to rotate.
Begin with either side and put the motion control lever into the neutral position. Adjust the motion control linkage by rotating the double nuts in the proper direction until the wheel stops rotating. FIG
-6 Move the motion control lever forward then into the neutral position and place it into the neu- tral slot. The wheel must be stopped completely at this point. Now do the same in reverse and re- lease the lever. The lever should return to neutral on its own.
