Parking Brake Adjustment
The parking brake system consists of two range
selector plates and two parking brake springs which
are located by the rear wheels of the unit. If the
parking brake needs to be adjusted the range selector
plates must be adjusted first, and then the length of
the parking brake springs must be set.

stop the engine and remove the ignition key.

moving. Jack up the rear of the machine and
secure with jackstands.
