SAFETY INFORMATION 33
Seat Belt Maintenance
•
Keep belt clean and dry.
•
Clean with mild soap solution and lukewarm water.
DANGER
Do NOT bleach or dye belt, as this may
cause severe loss of strength. Do NOT
install belt in a truck with a weakened
floor until the floor has been replaced or
reinforced.
•
Periodically inspect the following areas and replace any inadequate parts:
Buckle and Latchplate —
The buckle and latchplate should mate easily with a solid click
and release easily and quickly with moderate pressure on the release button. All metal seat
belt components should be free of signs of damage, corrosion or rust.
Webbing —
The webbing should show no signs of wear, fraying or holes, and it should be
reasonably free of dirt which could find its way into the retracting mechanism.
Retractors — The retractors should function smoothly and maintain an appropriate amount
of tension. Loose webbing is an indicator that maintenance is needed; it’s likely that a
too-loose belt will fail to tighten properly when necessary.
Seat Belt Mounting Components —
The tethering should be free of wear and debris; the
webbing should show no signs of wear, fraying or holes; and the metal components should
be free of signs of damage, corrosion or rust.
DANGER
Seat belt assemblies must be replaced after
an accident if they have been subjected to
loading by occupants (even if no damage is
obvious), or if they have been damaged by
an accident (bent retractor, torn webbing,
etc.). If there is any question regarding
belt or retractor condition, replace the
appropriate part.
