MODEL 330 OPERATOR'S MANUAL - Peterbilt Motors Company

Seats
• Make sure the belt of the unoccupied passenger seat is
fully wound up on its retractor, so that the belt tongue is
in its stowed position. This reduces the possibility of the
tongue becoming a striking object in case of a sudden
stop.
• Do not modify or disassemble the seat belts in your vehicle.
They will not be available to keep you and your passengers
safe.
• If any seat belt is not working properly, see an Authorized
Service Center for repair or replacement.
Tether Belts
Tether belts are installed on suspension seats. They help
secure the seat to the floor to restrain it in case of a sudden
stop or an accident.
Fixed Tethers
If your Model 330 has been equipped with fixed length tethers,
no manual adjustment is required. The same inspection
and replacement guidelines should be used as stated on
page 198.
Operating Instructions
WARNING! Do not remove, modify, or replace
the tether belt system with a different tether system.
A failed or missing tether belt could allow
the seat base to fully extend in the event of an
accident leading to greater injuries or death.
WARNING! Failure to adjust tether belts properly
can cause excessive movement of the seat in an
accident. This could lead to greater injuries to
you. Tether belts should be adjusted so that they
are taut when the seat is in its most upward and
forward position.
Tether Adjustment
• Make sure that the tether belt is attached to the cab floor
and seat frame. It should be routed through the buckle
on each side.
• Often the attachments are made using a split-type hook.
Make sure both halves of the hook are around the
anchor bracket.
• To lengthen the tether, turn the buckle to a right angle to
the webbing. Then pull the buckle. To shorten the tether,
pull on the strap.
