STARTING THE ENGINE
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.
NOTE: For starting in cold weather [below 40° F
(4° C)], use the optional cold start lever to release
the jackshaft drive belt and remove the hydrostatic
transmission from the starter cranking load. After
the engine has been started and warmed up, lower
the lever to re-engage the jackshaft drive belt.
Optional Cold Start Lever
2. For Model MT and MTL, 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: For Model MT and MTL, the choke
may not be required if the engine is warm.
IMPORTANT: If the engine fails to start after
approximately 10 seconds of cranking, the en-
gine should be checked before further cranking.
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
Kohler dealer for additional help.
3. After the engine starts, make sure the oil pres-
sure light goes off. If not, stop the engine imme-
diately and find the cause of the problem. Make
sure the oil pressure light is off prior to engaging
the mower blades and beginning operation.
4. For Model MT and MTL, 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.
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.
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 ad-
justed before operating the mower. DO
NOT disconnect safety switches; they are
for the operator’s protection.
