Wheel Drive Pins

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 Bail 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,

WARNING

Do not place the tiller on its side when changing the wheel drive positions as doing so could result in gasoline leaking from the fuel tank.

Failure to follow this instruc- tion could result in personal injury or property damage.

Figures 3-2 and 3-3) by removing the hairpin cotter (C).
