Tow Hooks
Tow hooks are provided as optional equipment. They are frame and brace mounted
at the front and rear of the bus.
[CAUTION] Never tow or push a vehicle equipped with an Allison automatic
transmission unless the drive shaft has been removed, or the rear wheels have
been raised off the ground. Do not tow by the front axle or any frame cross-
member. Damage to the wiring and/or the air lines can result. Optional tow
hooks are located at the front and/or rear of the vehicle under the bumper.
Tow hooks are designed to tow or pull with both hooks simultaneously. Do not
pull or tow with an individual hook. Bumpers provided on Blue Bird buses are
designed to protect the vehicle and occupants from front and rear collisions.
They are not designed for towing or jacking up the vehicle. Blue Bird does
NOT recommend towing or jacking the
vehicle by the bumpers.
[WARNING] Exercise extreme caution
when the drive shaft is removed on a
unit equipped with hydraulic brakes.
The parking brake becomes inopera-
tive when the drive shaft is disconnect-
ed. Do not leave the bus unattended
until taking appropriate measures
to prevent vehicle movement. Do not
work under the bus when supported
by bumper jacks. Use only appropri-
ate jack stands supporting frame rails
when under the bus.
