Adjustments
Prior to operating your tiller, carefully read and follow all instructions below.
Perform all adjustments to verify your tiller is operating safely and properly.
Clutch Cable
NOTE: Service the engine with oil and gasoline before checking this adjustment.
Refer to the separate Engine Operator's Manual packed with your tiller for proper
fuel and engine oil recommendations.
1. Position the tiller so the front counterweight is against a solid object, such
as a wall.
2. With the gear selection lever in NEUTRAL, start the engine. Refer to the
separate Engine Operator's Manual.
3. Standing on the right side of the tiller, examine the belt (inside the belt
cover). It should not be turning.
Do not put your fingers under the belt cover.
4. If the belt turns without the bail engaged, adjust it by un-threading the
internally threaded tube at the end of the cable a few turns clockwise —
when standing in the operator's position — and then retighten the nut
against the tube. See Figure 10.

5. Now move the shift lever to the FORWARD position.
6. Carefully engage the clutch by lifting the clutch control bail against the
handle. The wheels should spin.
7. If the wheels do not spin with the tiller 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.
8. Recheck both adjustments, and readjust as necessary.
9. After tilling, if the tines stop moving, re-adjust the cables.
NOTE: A secondary cable adjustment is available if you reach the point that
additional adjustment is needed. See the Service and Maintenance section
for secondary adjustment instructions.

The handle should be adjusted so that when the tiller is digging 3-4" into the soil,
the handle falls to about waste-high. Rotate the handle adjustment lock rearward, move the handle to the desired position and then lock into place by rotating the
handle adjustment lock forward to secure the handle. See Figure 11.
