STARTING THE ENGINE
CAUTION
Before operating the mower, read and un-
derstand all
Safety Instructions
and
Operat
ing Instructions
.
WARNING
NEVER run the engine in an enclosed or
poorly ventilated area. Engine exhaust
contains carbon monoxide, an odorless
and deadly gas.
1. Before attempting to start the engine, make sure
the operator is in the seat, the Forward Speed
Control is in
NEUTRAL-PARK
position, and the
blade clutch and parking brake are
DISENGAGED.
NOTE:
Release parking brake to prevent extra
load on the starter if the transmission neutral is
slightly out of adjustment.
CAUTION
A safety interlock switch system PRE-
VENTS CRANKING the engine with either
the Forward Speed Control or the blade
clutch (PTO) out of neutral. If the engine
cranks otherwise, the safety system is not
working and should be repaired or adjust-
ed before operating the mower. DO NOT
disconnect safety switches; they are for
the operator’s protection.
2. Move the choke lever to the
ON
position (for MBS
models) and move the throttle 1/4 to 1/2 open
(toward
FAST
). Turn the ignition switch to the
START
position to start the engine. Release the
key to
RUN
posi tion as soon as the engine starts.
NOTE:
For MBS models the choke may not be
required if the engine is warm.
IMPORTANT:
DO NOT
crank the engine con-
tinuously for more than 10 seconds at a time. If
the engine does not start, turn the key to the
OFF
position and allow a 60 second cool-down period
between starting attempts. Failure to fol low
these guidelines can damage the starter motor
and shorten battery life. Contact your Walker
dealer or authorized Kohler dealer for additional
help.
3. After the engine starts, gradually move the choke
to the
OFF
position, keeping enough choke on
to allow the engine to run smoothly as it warms
up. As soon as possible, move the choke to the
OFF
position (for MBS models).
IMPORTANT:
For MBS models make sure the
choke is in the
OFF
position during normal engine
operation; running with the choke in the
ON
posi-
tion
CAN
damage the engine.
ADJUSTING GROUND SPEED AND STEERING
CAUTION
Learn to START, STOP, and MANEUVER
the mower in a large, open area.
If the operator has not operated a machine
with LEVER STEERING OR DUAL TRAN-
SAXLES, steering and ground operation
should be learned and practiced until the
operator is completely comfortable han-
dling the machine BEFORE ATTEMPTING
TO MOW.
DANGER
Keep feet on footrest at all times when the
machine is moving. Never operate the
tractor without a deck or implement in-
stalled.
