Operating Instructions

Ignition Switch

The ignition switch is located on the right front of the 

body and is used to start and stop the engine.  The 

switch has three positions: “O” is the 

OFF

 position, 

ON (RUN)

 is the position that the key returns to after 

starting, and “S” is the 

START

 position.  When start

­

ing  the  engine,  turn  the  key  clockwise  to  the  “S” 

 

position.    Do  not  hold  the  key  in  the  “S”  position 

 

longer than 10 seconds.  If the engine does not start, 

return the key to the “O” position for at least 60 sec

­

onds before making a restart attempt.  Prolonged 

cranking can damage the starter motor and shorten 

battery life. Release the key when the engine starts, 

and it will return to the 

ON (RUN) 

position.  To stop 

the engine, rotate the key counterclockwise to the 

“O” position.

Circuit Breakers

A  manual  reset  5  amp  circuit  breaker  is  located 

above  the  hourmeter.   The  button  pops  out  if  the 

circuit breaker trips.  This circuit breaker protects the 

circuits to the safety switch relays and GHS.  In ad

­

dition, an auto reset 30 amp master circuit breaker 

is located in the rear right hand side of the chassis, 

and protects the charging system.

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.

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-
