SEAT BAR RESTRAINT SYSTEM
Description
The seat bar restraint system has a pivoting seat bar with
arm rests.
The operator controls the use of the seat bar. The seat
bar in the down position helps to keep the operator in the
seat.
Models with foot pedals have hydraulic valve spool
interlocks for the lift and tilt functions. The spool
interlocks require the operator to lower the seat bar in
order to operate the foot pedal controls.
When the seat bar is down, the PRESS TO OPERATE
LOADER Button is activated and the engine is running,
the lift, tilt and traction drive functions can be operated.
When the seat bar is up, the lift and tilt control pedals are
locked when returned to the NEUTRAL position.
Models with the Advanced Control System (ACS) have
mechanical interlocks for the handles and pedals. The
interlocks for the handles and pedals require the operator
to lower the seat bar in order to operate the selected
controls.
When the seat bar is down, the PRESS TO OPERATE
LOADER button is activated and the engine is running,
the lift, tilt and traction drive functions can be operated
using the selected controls (handles, or foot pedals).
When the seat bar is up, the handles and pedals are
locked when returned to the NEUTRAL position.
Models with Selectable Joystick Control (SJC) have
electrical deactivation of joystick functions. Activation of
functions require the operator to lower the seat bar.
When the seat bar is down, the PRESS TO OPERATE
LOADER button is activated and the engine is running,
the lift, tilt and traction drive functions can be operated.
When the seat bar is up, the joystick functions are
deactivated even though the joystick does not
mechanically lock.
Inspecting
Sit in the seat and fasten the seat belt. Engage the
parking brake. Pull the seat bar all the way down. Start
the engine. Press the PRESS TO OPERATE LOADER
Button.
Operate the hydraulic controls to check that both the lift
and tilt functions operate correctly. Raise the lift arms
until the attachment is about 600 mm off the ground.
Raise the seat bar. Move the hydraulic controls. Pedals
and handles (if equipped) must be firmly locked in the
NEUTRAL position (except joysticks). There must be no
motion of the lift arms or tilt (attachment) when the
controls are moved.
Lower the seat bar, press the PRESS TO OPERATE
LOADER Button, lower the lift arms. Operate the lift
control. While the lift arms are going up, raise the seat
bar. The lift arms must stop.
Lower the seat bar, press the PRESS TO OPERATE
LOADER Button, lower the lift arms and put the
attachment flat on the ground. Stop the engine. Raise the
seat bar. Operate the foot pedals and handles (if
equipped) to be sure they are firmly locked in the
NEUTRAL position (except joysticks).
Maintaining
See the SERVICE SCHEDULE for correct service
interval. (See SERVICE SCHEDULE on Page 67.)
Figure 125
Use compressed air to clean any debris or dirt from the
pivot parts (1) [Figure 125]. Do not lubricate. Inspect all
mounting hardware. The correct bolt torque is 35 Nm.
If the seat bar system does not function correctly, replace
parts that are worn or damaged. Use only genuine
Bobcat replacement parts.
WARNING
The seat bar system must deactivate the lift and tilt
control functions when the seat bar is up. Service the
system if hydraulic controls do not deactivate.
