ENGINE OPERATION - Operating Instructions 1 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. 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. NOTE With the key in the ON position, the engine warning lamps will come on momentarily and then go out. The engine warning lamps include: IT IS THE RESPONSIBILITY OF THE OWNER AND OPERATOR TO OPER- ATE THE VEHICLE IN A SAFE ENVI- RONMENT.
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. NOTE Check engine lamp; amber in color. 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. 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. CAUTION Stop engine lamp; red in color. 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. 22 Y53-1183-1E1 (04/16/18)
