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.
