time to cool.

at half throttle for 3 to 5 minutes before shutting off
engine.

 

CAUTION

To prevent injury to bystanders, or damage to the
equipment, do not rest the weight of the deck and lift arm
on the latch. Weight of deck and lift arm may cause the
deck to fall when the latch is released.

!

NOTICE

Do not transport with the arms resting on the latch.
Transport latches are only used to prevent accidental
lowering of the cutting units.
