These vehicles are equipped with Kidde Plastic-Handle or Push Button 'Pindicator' Fire Extinguishers that may become clogged, preventing the extinguisher from discharging as expected or excessive force may be needed to activate the extinguisher.

ON CERTAIN TRUCKS EQUIPPED WITH CATERPILLAR DIESEL ENGINES, THE VARIABLE VALVE ACTUATION OIL LINE MAY WEAR AGAINST THE SHARP EDGE OF THE CYLINDER HEAD IF NOT POSITIONED CORRECTLY.
