Operating Instructions

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-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

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 adjust- ed before operating the mower. DO NOT disconnect safety switches; they are for the operator’s protection.

2.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 posi- tion as soon as the engine starts.

NOTE: The choke may not be required if the engine is warm.

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.

3.After the engine starts, 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.

IMPORTANT: Make sure the choke is in the OFF position during normal engine operation; running with the choke in the ON position CAN damage the engine.

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 machine with LEVER STEERING OR DUAL TRAN- SAXLES, steering and ground operation should be learned and practiced until the operator is completely comfortable han- dling the machine BEFORE ATTEMPTING TO MOW.

DANGER

Keep feet on footrest at all times when the machine is moving.
