OPERATION
340
Engine Overspeed
This vehicle is equipped with a diesel engine and should not be
operated in an area with a concentration of hydrocarbon vapors (for
example gasoline or diesel fuel fumes). Be especially cautious of
low-lying or closed-in areas. The vapors may be drawn into the engine
through the air intake and cause the engine to overspeed. Hot carbon
and other sparks may come from the exhaust system, and cause an
explosion and fire.
If the vehicle is in an area where hydrocarbon vapors may be present,
shut the engine off immediately if any abnormalities are experienced.
DO NOT leave it unattended.
The diesel engine will operate on any fuel which
enters the cylinder, whether it is from the injectors
or from the air intake system. Therefore, if any
solvent is used to flush out the air cleaner
element, the engine may overspeed during
start-up. Engine damage and severe injury and/or
death from burns or explosion can occur.
Idling
Diesel engines are electronically governed. The idle speed is
pre-programmed from the manufacturer. Low idle speed is adjustable
within certain limits (for most engines between 600 to 750 rpm).
The common belief that idling a diesel engine causes no engine
damage is wrong. Idling produces sulfuric acid, which breaks down the
oil and eats into bearings, rings, valve stems and engine surfaces.
