3.Pull the cable upwards to obtain slack, and, from right to left, hook the “Z” end of the cable into the bracket on the clutch control (beneath the handle panel) as shown in Figure 11. Tighten the nut against the cable bracket.

NOTE: Do not overtighten control wire. Too much tension may cause it to break.

FINAL CLUTCH ADJUSTMENT

IMPORTANT: Service the engine with oil and gasoline before checking this adjustment. Refer to the separate engine manual packed with your tiller.

1.Position the tiller so the front counterweight is against a solid object, such as a wall. With the gear selection lever in NEUTRAL, start the engine. Refer to Operation section.

NOTE: Keep hands out of belt area while unit is operating.

2.Standing on the right side of the tiller, visually examine the belt (inside the belt cover). It should not be turning.

If the belt turns with the unit in neutral, adjust by moving the hex nut below the cable bracket down a few turns. See Figure 11. Tighten the upper hex nut against the bracket.

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

4.If the wheels do not spin with the unit in forward, adjust by moving the hex nut which is above the cable bracket up a few turns. Tighten the bottom hex nut against the bracket.

Recheck both adjustments, and readjust as neces- sary. Make certain hex nuts at cable bracket are tight (do not overtighten control cable).

NOTE: If additional adjustment is required, it may be necessary to remove the belt cover, and move the hex nuts at the other end of the clutch cable to increase belt tension.

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 14 p.s.i. on 14 inch tires and 20 p.s.i. on 16 inch tires. (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.
