SEAT BAR RESTRAINT SYSTEM
Description
The seat bar restraint system has a pivoting seat bar with
arm rests and has spring loaded interlocks 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.
The interlocks require the operator to lower the seat bar
in order to operate the foot pedal.
When the seat bar is up, the lift and tilt pedals are locked
when returned to the NEUTRAL POSITION.
Inspecting The Seat Bar
Sit in the seat and fasten the seat belt. Engage the
parking brake. Pull the seat bar all the way down. Start the
engine. 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, lower the lift arms. Operate the lift
pedals. While the lift arms are going up, raise the seat bar
and the lift arms should stop.
Lower the seat bar, lower the lift arms and place 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.
Maintaining The Seat Bar
See the SERVICE SCHEDULE, Page 1–3 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).
Use a general purpose grease to lubricate the seat bar
pivot points at each side of the cab [A].
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 Melroe replacement parts.
AVOID INJURY OR DEATH
The seat bar system must lock the lift and tilt
control pedals in neutral when the seat bar is
up. Service the system if pedals do not lock
correctly.
