Attaching Control Rod

•  Make sure the handle assembly is in the highest 

position. Refer to Know Your Tiller section.

•  Remove hairpin clips from control rod, (rubber 

washers to remain on control rod).

•  Insert the shorter, (angled), end of the control rod 

through the indicator bracket on the shift cover and 

secure with hairpin clip that was previously removed. 

See Figure 5.

•  Insert the longer end of the control rod through the 

hole in the gear selector handle and secure with 

hairpin clip.See Figure 6. 

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 for proper fuel and 

engine oil recommendations.
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 the 

separate engine manual.
Standing on the right side of the tiller, examine the belt 

(inside the belt cover). It should not be turning.

WARNING: Do not put your fingers 
under the belt cover.

If the belt turns without bail engaged, 

adjust by 

unthreading the internally threaded tube at the end 

of the cable a few turns clockwise (when standing in 

operator’s position) and then retighten the nut against 

the tube.

Now move the shift lever to 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 main-

tained on both tires.
