Model 330 PB1318 3/01
– 101 –
• Always keep the brakes adjusted and in proper condi-
tion. See
page 154
.
• Obey speed limits and all traffic signals.
• When driving downhill, select one gear lower than the
gear you would use going up the hill. And use the brakes
properly—do not ride them.
• Do not exceed maximum governed engine speed (as
specified in the
Engine Operation and Maintenance
Manual
).
WARNING! Do not exceed the specified load rat-
ing. Overloading can result in loss of vehicle
control and serious personal injury, either by
causing component failures or by affecting vehi-
cle handling. Exceeding load ratings can also
shorten the service life of the vehicle.
• The components of your vehicle are designed to pro-
vide satisfactory service if the vehicle is not loaded
in excess of either the gross vehicle weight rating
(GVWR), or the maximum front and rear gross axle
weight ratings (GAWRs). (Axle weight ratings are
listed on the driver's door edge.)
NOTE: For your safety and the safety of others, fol-
low routine and periodic maintenance schedules for
all components on your vehicle. See Table 3,
“Maintenance Schedule,” Page 124
Air Suspension Height/Air Pressure
Your vehicle may have an air suspension. A deflation switch
on the dash allows you to exhaust the air in the suspension,
which allows you to lower the height of your vehicle for load-
ing. On tractors, the deflate switch allows you to lower the
fifth wheel to slide under a trailer.
A guard on the switch prevents you from accidentally deflat-
ing the suspension.
WARNING! Do not operate the Air Suspension
Deflate Switch (Dump Valve) while driving. Sud-
den deflation while your vehicle is moving can
affect handling and control and could lead to an
accident. Use this switch only when your vehicle
is not moving.
CAUTION: Operating a vehicle with air suspen-
sion bags either overinflated or underinflated
may cause damage to driveline components. If a
vehicle must be operated under such condi-
tions, do not exceed 5 mph (8 km/h).
