Operator Restraint System Replacement
DESCRIPTION
The seat belt, hip restraint brackets, seat and mount-
ing, hood, and latches are all part of the operator re-
straint system. Each item must be checked to make
sure it is attached securely, functions correctly, and is
in good condition. See Figure 20.
Emergency Locking Retractor (ELR)
When the ELR style seat belt is properly buckled
across the operator, the belt will permit slight operator
repositioning without activating the locking mecha-
nism. If the truck tips over, travels off a dock, or
comes to a sudden stop, the locking mechanism will
be activated and hold the operator's lower torso in the
seat.
A seat belt that is damaged worn or does not operate
properly will not provide protection when it is needed.
The end of the belt must fasten correctly in the latch.
The seat belt must be in good condition. Replace the
seat belt if it is damaged or worn. See Figure 20.
NOTE:
The following seat belt operation checks must
be performed three times before replacing the seat
belt assembly:
•
With the hood closed and in the locked posi-
tion, pull the seat belt slowly from the retractor
assembly. Make sure the seat belt pulls out
and retracts smoothly. If the seat belt does not
pull out of the retractor assembly, the internal
latch may be locked.
Pull firmly on the seat belt and hold for a mo-
ment to remove slack from the belt in the re-
tractor. Release the seat belt. Seat belt will re-
tract and the internal latch will unlock. If the
seat belt cannot be pulled from the retractor
assembly or the belt will not retract, replace the
seat belt assembly.
•
With the hood closed and in the locked posi-
tion, pull the seat belt with a sudden jerk. Make
sure the seat belt will not pull from the retractor
assembly. If the seat belt can be pulled from
the retractor, when it is pulled with a sudden
jerk, replace the seat belt assembly.
•
With the hood in the open position, make sure
the seat belt will not pull from the retractor as-
sembly. If the seat belt can be pulled from the
retractor, with the hood in the open position, re-
place the seat belt assembly.
Make sure the seat rails and hood latch are not loose.
The seat rails must lock securely in position but move
freely when unlocked. The seat rails must be securely
attached to the mounting surface. The hood must be
fully closed. Lift the hood to make sure it is closed and
will not move.
Adjust hood and hood latch when any of the parts of
the operator restraint system are installed or replaced.
See section Hood, Seat, and Side Covers Replace-
ment in this manual for the adjustment procedures for
the hood.
