PACCAR

WARNING! Combustible vapors near the air
intake system could be ingested into the engine,
causing the engine to suddenly accelerate and
overspeed or explode. This condition could
result in an unexpected increase in engine rpm
and/or fire, resulting in personal injury or prop-
erty damage. Do not operate your vehicle in area
where combustible chemicals or vapors may be
present.

IT IS THE RESPONSIBILITY OF THE OWNER
AND OPERATOR TO OPERATE THE VEHICLE IN
A SAFE ENVIRONMENT.

NOTE: Numerous safety devices (ie engine shutoff
devices) are available to minimize the risk of engine
overspeeding caused by combustible vapors being
ingested into the air intake system.
