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 en-
gine cranks otherwise, the safety system 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 ON
(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 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 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.
