Now move the shift lever to FORWARD (Wheels Forward) position. Carefully engage the clutch by lifting the clutch control bail against the handle. The wheels should spin.

If the wheels do not spin with the unit in forward, adjust by unthreading the tube at the end of the cable a few turns counter-clockwise, (when standing in operator’s position), and then retighten the nut against the tube.

Recheck both adjustments, and readjust as necessary.

NOTE: A secondary cable adjustment is available if you reach the point that additional adjustment is needed. Remove the belt cover and move the hex nuts at the other end of the cable towards the end of the casing. Then readjust the hex nuts at the handle.

TIRE PRESSURE

The tires on your unit may be over-inflated for shipping purposes. Reduce the tire pressure before operating the unit. Recommended operating tire pressure is approximately 20 p.s.i. (check sidewall of tire for tire manufacturer’s recommended pressure).

WARNING: Maximum tire pressure under any circumstances is 30 p.s.i. Equal tire pressure should be maintained on both tires.
