Operating Instructions
35
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,
the parking brake is ENGAGED, and the blade
clutch is DISENGAGED.
CAUTION
A safety interlock switch system PRE-
VENTS CRANKING the engine with any one
of these three controls in the OPERATING
position: (1) Forward Speed Control out of
neutral, (2) blade clutch (PTO) engaged, or
(3) parking brake disengaged. If the engine
cranks otherwise, the safety system is not
working and should be repaired or ad justed
before operating the mower. DO NOT dis-
connect safety switches; they are for the
operator’s protection.
2. 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.
IMPORTANT: If the engine fails to start after
approximately 10 seconds of cranking, the en-
gine should be checked before further crank ing.
Turn the key to the OFF position and allow a 60
second cool-down period between starting at-
tempts. 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 horn goes o. If not, stop the engine im-
mediately and nd the cause of the problem.
Make sure the oil pressure horn is o prior to
engaging the mower blades and beginning op-
eration.
ADJUSTING GROUND SPEED AND STEERING
IMPORTANT: If the DS52 mower deck is in-
stalled on the tractor, make sure the dolly wheel
is retracted BEFORE moving.
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.
1. Move the FSC out of NEUTRAL-PARK position
to the desired forward speed. DO NOT hold
for ward on steering levers. It is not necessary
to hold the FSC lever in position since a friction
lock maintains the selected lever position (and
forward travel speed).
