Adjusting the Self-Propel
Drive
If the machine creeps either forward or rearward when
the engine is on and the self-propel drive bail is in
neutral, complete the following procedure:
1. Shut off the engine, wait for all moving parts to
stop, and remove the spark-plug wire.
2. Raise the cutting blades to the highest position.
3. Squeeze the self-propel drive bail to the handle
until the transmission is fully stroked.
•
If the bail contacts the handle, release the
bail. If the bail does not contact the handle,
then proceed to step 4.
•
Loosen the top adjustment nut 1 turn, and
tighten the bottom adjustment nut.
•
Squeeze the bail to the handle.
•
Repeat this step until there is a gap of up to
3.2 mm (1/8 inch) between the self-propel
drive bail and the handle.
•
Once the gap is achieved, proceed with step
4.
