SAFETY CHECKS
This bus conforms to all Federal Motor
Vehicle Safety Standards applicable
at the time of manufacture, and in
addition, incorporates other important
features. However, even with these
safety features, continued safe and
dependable operation depends greatly
on regular bus maintenance.
To retain the safety, dependability
and emission control performance
originally built into the vehicle, it
is essential that it receive regular
periodic inspection, maintenance and
service parts replacement.
Listed below are items that should be
checked prior to taking the vehicle
onto the road along with the pre-
trip inspection. Any deficiencies or
irregularities should immediately be
brought to the attention of service
personnel. Broken, incomplete,
damaged or worn articles should be
replaced/repaired after evaluation by
qualified personnel.

retractor and attaching point for
proper operation and for damage.

components found to be defective
or inoperative should be repaired or

DOORS, WINDOWS & EMERGENCY

and latching operations. Check that
window emergency release levers
work properly and that windows open,
close and latch properly. Check that
all compartment and passenger doors
are securely closed by attempting to
re-open after each use. Also check for
broken, missing or loose parts that can
prevent positive latching.
WHEEL ALIGNMENT & TIRE
BALANCE
u
In addition to uneven or abnormal
tire wear, the need for wheel alignment
service may be indicated by a pull
to the left or right while driving on a
straight and level road. The need for
wheel balancing is usually indicated
by vibration of the steering wheel or
seat while driving at normal highway
speeds. Contact service personnel for
repair if either condition is present.
FLUID LEAKS
u
Check for fuel, water, oil or other
fluid leaks by observing the surface
beneath the bus after it has been
parked for a period of time (water
dripping from the air conditioning
system is normal). If diesel fuel or
gas fumes are noticed at any time,
the cause must be determined and
immediately corrected to reduce the
risk of fire.
