346 Service and Maintenance
Cab Interior Inspection
Safety/Emergency Equipment: Prior to
entering the cab, verify that the vehicle is
equipped with the proper equipment.
Walk around the vehicle and check that
all steps and grab handles, inside and out,
as well as behind, are tight and clean.
Use extreme caution and maintain three
points of contact at all times.
Doors: Check the door latches for positive
closing, latching, and locking. Ensure the
windows are clean and operate properly
and smoothly.
Accelerator: Press the accelerator pedal
and verify that it operates smoothly
without any binding or irregular feel.
Remove foot from the accelerator and
make sure the engine returns to idle
immediately.
Steering Play: Check for smooth
operation. Check for excessive looseness
in the steering linkages. The steering
wheel should have less than 10 degrees of
free play: approximately 5 cm (2 in) at
the rim of a 45 cm (18 in) steering wheel.
Seats: Be sure the seats are firmly
engaged to avoid forward or rearward
movement when starting or stopping.
Make sure that the seats and tether
straps are free from damage and secured
to the floor.
Horn(s): Check to see that the horn(s)
operate properly.
Mirrors: Check the mirrors for proper
adjustment, damage, cleanliness, and
proper mounting. If equipped, check the
power mirrors and the heated mirrors for
proper operation.
Windshield and Wipers: Check the
windshield for cracks, dirt, illegal stickers,
or other viewing obstructions. Ensure the
wipers and windshield washer are
functioning properly.
Heater/Defroster: Check to be sure that
heater/defroster is working. Verify
adequate airflow from the louvers and
vents. Operate the temperature and mode
controls to verify proper operation.

Additional Maintenance and Care
(Lubrication)
Lubrication and Fluids
All new vehicles are lubricated at the
factory. Once the vehicle is in operation,
regular lubrication and maintenance
intervals (based on the type of service and
road conditions) must be established and
performed. Load weight, vehicle speed, road
conditions, and weather conditions all
contribute to lubrication frequency.
Performing thorough lubrication and
maintenance at the specified intervals will
ensure an outstanding vehicle life and will
reduce overall operating expense.
Only lubricants of superior quality should be
used. The use of inferior products will
reduce the service life of the vehicle or
result in failure of its components.
Components requiring lubrication and fluid
check shown in this manual are typical
representations.
