(b) HOLD: Blade is stopped and held in this position.
(c) LOWER:

REMARK
When released from FLOAT position, this lever will not
return to HOLD position, so it must be moved back by
hand.
If the engine is stopped when the lever is at the FLOAT
position, the control lever will automatically return to the
HOLD position.
Before starting the engine, check that the blade control
lever is at the HOLD position. The engine will not start
when it is at the FLOAT position.
In cold weather, it will take time for the lever to be held at
the HOLD position, so hold the lever by hand at the HOLD
position for at least 1 second.
