OPERATOR CAB (Cont'd)
Seat Bar Description
The seat bar system has a pivoting seat bar with arm rests
and has spring loaded latches for the
lift and tilt control
pedals.
The operator controls the use of the seat bar. The seat bar
in
the down position helps to keep the operator
in
the seat
and unlocks the foot pedals.
When the seat bar
is
up, lift and tilt pedals are locked
in
neutral position.
