Operation
SECTION 5 — OPERATION
Operation Safety
WARNING
Operation of a diesel engine near flammable
vapors in the air may cause the engine speed
to increase uncontrollably and overspeed.
If
this situation occurs, mechanical damage, fire,
explosion, personal injury or death could result.
Turning off the ignition switch will not slow or
stop the engine due to uncontrollable fueling
of the engine through flammable vapors being
drawn into the engine air inlet.
Operation of
components such as starter, alternator, electric
motors, etc.
and static electricity could also
ignite flammable vapors.
Do not operate the truck in the possible presence
of flammable vapors unless both a complete
hazard analysis is performed and necessary
additional safety processes and/or equipment
such as vapor testing, air intake shutoff devices,
ventilation, etc.
are utilized. The operator is
responsible for using those processes and/or
equipment to ensure that the diesel engine
and all other components on the truck can be
operated safely under the specific conditions
and hazards that may be encountered.
WARNING
Do not exceed the truck’s gross axle weight,
gross vehicle weight, and gross combination
weight ratings.
Exceeding these ratings by
overloading can cause component failure
resulting in property damage, personal injury, or
death.
WARNING
Always use occupant restraint system when
vehicle is moving. Any location in the vehicle not
equipped with a seat belt should not be occupied
when the vehicle is being operated. In the event
of a vehicle accident or sudden, unexpected
movement, failure to properly use an occupant
restraint system could result in personal injury
or death.
WARNING
Always use the ashtray(s) provided for disposing
of cigar, cigarette, or pipe ashes and tobacco.
Failure to use an ashtray is a fire hazard and
could result in property damage, personal injury,
or death.
