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
DIS-
ENGAGED.
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 out of neutral,
or the blade clutch (PTO) engaged. If the
engine cranks otherwise, the safety sys-
tem is not working and should be repaired
or ad justed 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 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
position as soon as the engine starts.
NOTE:
The choke may not be required if the
engine is warm.
IMPORTANT:
DO NOT
crank the engine
continuously 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
follow these guidelines can damage the starter
motor and shorten battery life. Consult your
Walker dealer or authorized engine 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.
IMPORTANT:
Make sure the choke is in the
OFF
position during normal engine operation;
running with the choke in the
ON
position
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 ma chine
with LEVER STEERING OR DUAL HYDRO-
STATIC TRANSMISSIONS, steer
ing and
ground operation should be learned and
practiced until the operator is completely
comfortable handling the ma
chine BE-
FORE ATTEMPTING TO MOW.
DANGER
Keep feet on footrests at all times when
the machine is moving. Never operate the
tractor without a deck or implement in-
stalled.
