INTRODUCTION
This Section describes the location and
function of the controls on your tiller. Refer
to the following Section, Operation for de­
tailed operating instructions.
Practice using these controls, with the en­
gine shut off, until you understand the op­
eration of the controls and feel confident
with each of them.
ENGINE CONTROLS
Refer to the engine manufacturer’s Engine
Owner’s Manual (included In the tiller liter­
ature package) to identify the controls on
your engine.
IMPORTANT: The control for stopping the
engine is located on the engine.
WHEEL DRIVE PINS
Each wheel is equipped with a wheel drive
Klik pin (A, Figures 3-2 and 3-3) that se­
cures the wheel to the wheel shaft (B). The
wheels can be positioned in either a
WHEEL DRIVE or a FREEWHEEL mode.
A 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.
Before starting the engine, put both wheels
in the WHEEL DRIVE position by inserting
the wheel drive Klik pins through the wheel
hubs and the wheel shaft. Doing so “locks”
the wheels to the wheel shaft, causing the
wheels to turn when either the
Figure 3-1: Tiller features and controls. See separate Engine Owner’s Manual to identify
engine controls.
Forward Clutch Bail (all models) or the Re­
verse Clutch Control (Models 643B &
645A) 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 you manually move the tiller.
To place the wheels in WHEEL DRIVE or
FREEWHEEL:
1. Stop engine, disconnect spark plug wire
from spark plug and allow engine to cool.
A WARNING:
Do not place
tiller on its side when changing
wheel drive positions. Doing so
could result in gasoline leaking
from the fuel tank.
Failure to follow this instruction
could result in personal Injury
or property damage.
2. Raise one wheel about one inch off the
ground and place a sturdy support under
the transmission.
3. Remove Klick Pin (A. Figures 3-2 and 3­
3) from wheel drive shaft (B).
4. FOR WHEEL DRIVE MODE (Figure 3-2):

port from beneath the transmission.
5. FOR FREEWHEEL MODE (Figure 3-3):
