4.5 STARTING THE ENGINE

CAUTION
DO NOT USE STARTING FLUIDS. Use of starting
fluids in the air intake system may be potentially
explosive or cause a "runaway" engine condition
that could result in engine damage and/or
personal injury.
1. Be sure the fuel shutoff valve, located behind the
operator's seat, is completely open.
2. Sit in the operator's seat, fasten seat belt and place
the steering control levers in the neutral position.
3. Engage the parking brake.
4. Place the PTO switch in the disengaged position.
5. If the engine is cold, choke the engine as needed.
6. Move the engine throttle control to about half engine
speed.
7. Turn the ignition key to the START position and
release the key as soon as the engine starts. Do
not hold the key in the START position for more
than 15 seconds at a time. Allow at least 60
seconds between each cranking attempt to prevent
overheating of the starter motor. Prolonged cranking
can damage the starter motor and shorten battery
life.
8. Allow engine to warm before operating the mower.
