engage the choke before starting a cold engine
(Figure 7).
Note: A warm or hot engine may not require
choking.
4. Turn the ignition key to Start to energize the
starter. When the engine starts, release the key
(Figure 7).
Important: Do Not engage the starter for
more than 5 seconds at a time. If the engine
fails to start, allow a 60 second cool-down
period between attempts. Failure to follow
these instructions can burn out the starter
motor.
5. Once the engine starts, move the lever to the
detent position. If the engine stalls or hesitates,
move the lever partially forward for a few seconds.
Operating the Blades
The blade control switch, represented by a power
take-off (PTO) symbol, engages and disengages
power to the mower blades. This switch controls
power to any attachments that draw power from the
engine, including the mower deck and cutting blades.
Engaging the Blades
1. Release pressure on the motion control levers and
place the machine in neutral.
2. Move the throttle midway to the Fast position.
Note: Always engage the blades with the throttle
in the midway position.
3. Pull out on the blade control switch, to the On
position, to engage the blades (Figure 8).

unauthorized persons from starting engine.
