SEAT BAR RESTRAINT SYSTEM (Foot Pedals)

Description

2.

The seat bar restraint system has a pivoting, spring assist
seat bar with arm rests and has spring loaded interlocks
for the lift and tilt functions.

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

The interlocks require the operator to lower the seat bar
in order to operate the foot pedal controls.

When the seat bar is up, the lift and tilt control functions
are locked when returned to the NEUTRAL POSITION.

Seat Bar Inspection

Sit in the seat and fasten the seat belt. Engage the
parking brake. Pull the seat bar all the way down. Start the
engine. Loaders without seat sensors press the green
PRESS TO OPERATE Button. Operate each foot pedal
to check both the lift and tilt functions. Raise the lift arms
until the bucket is about 2 feet (600 mm) off the ground.

Raise the seat bar. Try to move each foot pedal. Pedals
must be firmly locked in neutral position. There must be
no motion of the lift arms or tilt (bucket) when the pedals
are pushed.

Pull the seat bar down. Loaders without seat sensors
press the green PRESS TO OPERATE Button. Lower the
lift arms. Operate the lift pedal. While the lift arms are
going up, raise the seat bar and the lift arms should stop.

Lower the seat bar. Loaders without seat sensors press
the green PRESS TO OPERATE Button. Lower the lift
arms and put the bucket flat on the ground. Stop the
engine. Raise the seat bar and operate the foot pedals to
be sure that the pedals are firmly locked in the neutral
position. Unbuckle the seat belt.

Seat Bar Maintenance

See the SERVICE SCHEDULE Page 1–3 and on the
loader for correct service interval.

Clean any debris or dirt from the moving parts [A] & [B].
Inspect the linkage bolts and nuts for tightness. The
correct torque is 25–28 ft.–lbs. (34–38 Nm).

If the seat bar system does not function correctly, check
for free movement of each linkage part. Check for
excessive wear. Adjust pedal control linkage. Replace
parts that are worn or damaged. Use only genuine Bobcat
replacement parts.
