WARNING!
It is important to remember that any
time a vehicle is involved in an acci-
dent, the entire seat belt system must
be replaced. Unexposed damage
caused by the stress of an accident
could prevent the system from func-
tioning properly the next time it is
needed. Failure to comply may result
in death or personal injury.

Inspection Guidelines
Follow these guidelines when
inspecting for cuts, fraying, extreme
or unusual wear of the webbing,
and damage to the buckle, retractor,
hardware, or other factors. Damage to
these areas indicates that belt system
replacement is necessary.
WARNING!
Replace the entire belt system (retrac-

any one part is necessary. Unexposed
damage to one or more components
could prevent the system from func-
tioning properly the next time it is
needed. Failure to comply may result
in death or personal injury.
1. Check the web wear in the system.
The webbing must be closely
examined to determine if it is
coming into contact with any sharp
or rough surfaces on the seat or
other parts of the cab interior.

the area where almost constant
movement of the seat belt
webbing occurs because of
relative movement between the
seat and cab.
3. Check the Komfort-Latch for
cracks or possible damage and
check for proper operation.
4. Check buckle and latch for proper
operation and to determine if
latch plate is worn, deformed, or
damaged.
