Operating Instructions

Circuit Breakers

Depending on model, either one or two manual reset circuit breakers are located on the instrument panel. Each has a button that pops out if the circuit breaker trips. For Models MT, MTEFI and MTLEFI, the 7 amp circuit breaker protects the safety circuits and GHS. For Model MTL, the 7 amp circuit breaker protects the warning lights/horn, safety circuits and GHS. For Model MTL, the 10 amp circuit breaker protects the headlights. For Model MT, the 30 amp circuit breaker (located near the battery) protects the instrument panel and headlights. For Model MTL, the two (2) 30 amp circuit breakers protect the instrument panel, starter solenoid and ’fan’ control module. For Models MTEFI and MTLEFI, the 30 amp circuit breaker protects the instrument panel, headlights, and starter solenoid, and a 20 amp fuse protects the ECU.

STARTING THE ENGINE

CAUTION

Before operating the mower, read and understand all Safety Instructions and Operating 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-PARKposition, 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.

CAUTION

Asafety 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.

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.

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.
