WARNING
Never allow either of the
wheels to be in the
FREEWHEEL position when
the engine is running. Always
put both wheels in the WHEEL
DRIVE position before starting
the engine.
Failure to comply could cause
loss of tiller control, property
damage, or personal injury.
Each wheel is equipped with a Wheel
Drive Pin (A, Figures 3-2 and 3-3) that
secures the wheel to the wheel shaft (B).
The wheels can be positioned in either a
WHEEL DRIVE or a FREEWHEEL mode.
Before starting the engine, put both
wheels In the WHEEL DRIVE position by
inserting the Wheel Drive Pins through
the wheel hubs and the wheel shaft. This
“locks" the wheels to the wheel shaft,
causing the wheels to turn when either
the Forward Clutch Ball or the Reverse
Clutch Control Is engaged.
Use the FREEWHEEL mode only when the
engine is not running. In FREEWHEEL,
the Wheel Drive Pins are placed only
through the holes in the wheel shaft (not
the wheel hubs), thus allowing the wheels
to turn freely when the tiller is pushed or
pulled by hand.
To Place the Wheels In WHEEL DRIVE or
FREEWHEEL:
1. Stop the engine, disconnect the spark
plug wire from the spark plug and allow
the engine to cool.
2. Raise one wheel off the ground and
place a sturdy support under the
transmission.
3. Remove the wheel drive pin (A,
