STOPPING THE BOBCAT LOADER

Using The Steering Levers or Joysticks

When the steering levers or joysticks are moved to the
neutral position, the hydrostatic transmission will act as a
service brake to stop the loader.

SEAT BAR RESTRAINT SYSTEM

Operation

Figure 27

The seat bar restraint system has a pivoting seat bar with
arm rests (1) [Figure 27].

The operator controls the use of the seat bar. The seat
bar in the down position helps to keep the operator in the
seat.

WARNING

AVOID INJURY OR DEATH

When operating the machine:

Keep the seat belt fastened snugly.

The seat bar must be lowered.

Keep your feet on the pedal controls or footrests
and hands on steering levers.

W-2261-0799

When the seat bar is down, the PRESS TO OPERATE
LOADER button is activated, and the brake is released,
the lift, tilt, and traction drive functions can be operated.
(Traction drive will operate only when the engine is
running.)

When the seat bar is up, the lift, tilt and traction drive
functions are deactivated and both foot pedals (if
equipped) will be locked.

WARNING

Before you leave the operator’s seat:

Lower the lift arms, put the attachment flat on the
ground.

Stop the engine.

Engage the parking brake.

Raise seat bar.

(Foot Pedal Controls) Move pedals until both
lock.

(Advanced Control System - ACS) Move the
hydraulic controls to the NEUTRAL POSITION to
make sure that both lift and tilt functions are
deactivated.

The seat bar system must deactivate the lift and
tilt control functions when the seat bar is up.
Service the system if hand controls do not
deactivate. 

(Selectable Joystick Control - SJC) Move the
joysticks to the NEUTRAL POSITION to make
sure that travel and hydraulic functions are
deactivated.

The seat bar system must deactivate these
functions when the seat bar is up. Service the
system if controls do not deactivate.
