1. This adjustment must be made with drive wheels
turning. First raise the frame and block up so drive
wheels can rotate freely.
Engine must be running so motion control
adjustment can be performed. Contact with
moving parts or hot surfaces may cause personal
injury.
Keep hands, feet, face, clothing and other body
parts away from rotating parts, muffler and other
hot surfaces.

7. Move motion control lever forward and reverse, then
back to neutral. Wheel must stop turning or slightly
creep in reverse.
Note: Motion control lever must be in neutral while
making any adjustments.
8. Open throttle to fast. Make sure wheel remains
stopped or slightly creeps in reverse, re-adjust if
necessary.
