STARTING THE ENGINE
CAUTION
Before operating the mower, read and un-
derstand all Safety Instructions and Oper-
ating 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
).
3. Turn the ignition key to the
ON (RUN)
position
and observe the glow plug activation light (this
light may not come on if the engine is hot). As
soon as the glow plug activation light goes off,
immediately
turn the key clockwise to the “S”
position to start the engine. Release the key
when the engine starts, and it will return to the
ON (RUN)
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 seconds before making
another starting attempt.
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.
Consult your Walker dealer or authorized
Kohler dealer for additional help.
TROUBLESHOOTING NOTE:
If the engine
cranks but does not start, check the following:
● Engine is equipped with a mechanical fuel
pump and the fuel system may need to be
primed in certain conditions (after running
out of fuel or after fuel system
maintenance). See instruction for
Fuel
Pump Priming on page 30
.
● Is the fuel valve solenoid operating? Look
at the exhaust pipe when cranking the
engine - no smoke indicates no fuel is
reaching the cylinder. If the solenoid is not
operating, contact your authorized Kohler
engine dealer.
● Are the glow plugs operating? Look at the
exhaust pipe when cranking the engine
- white smoke indicates improper glow
plug operation and inadequate preheat. If
the glow plugs are not operating, consult
your authorized Kohler engine dealer.
4. After the engine starts, make sure the oil pres-
sure light goes off. If not, stop the engine
immediately and find the cause of the prob-
lem. Make sure the oil pressure light is off
prior to engaging the mower blades and begin-
ning operation.
