PACCAR recommends the installation of
an air intake shutoff device or a similar
safety device to minimize the risk of
overspeeding, as can occur when the
vehicle is being operated in a combustible
environment, such as from a fuel spill or
gas leak.
WARNING
Combustible vapors near the air intake
system could be ingested into the en-
gine, causing the engine to suddenly
accelerate and overspeed. This condi-
tion could result in operator losing con-
trol of the vehicle if an unexpected in-
crease in engine rpm occurs. Combus-
tible vapors could also cause a fire.
DO NOT operate your vehicle in an
area where combustible chemicals or
vapors may be present. Failure to
comply may result in death, personal
injury, equipment or property damage.
NOTE
IT IS THE RESPONSIBILITY OF THE
OWNER AND OPERATOR TO OPER-
ATE THE VEHICLE IN A SAFE ENVI-
RONMENT.
NOTE
If the engine is running, do not in-
crease engine speed (rpm) or operate
the vehicle until the low oil pressure
warning lamp turns off.
CAUTION
Engaging the starter motor for more
than 30 seconds in any five minute pe-
riod may cause it to overheat and can
damage the starter.
• If starter is engaged continuously
for 30 seconds, you must wait five
minutes before trying to start the
engine to allow the starter motor to
cool down.
With the key in the ON position, the engine
warning lamps will come on momentarily
and then go out. The engine warning
lamps include:
Check engine lamp; amber in color.
Stop engine lamp; red in color.
