OPERATION 301
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.
DANGER
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.
Note:
Avoid excessive idling. If the vehicle is parked for more than 5 minutes, stop
the engine. An engine can burn from 3 to 5.5 liters (0.75 to 1.5 gallons) of fuel per
hour while idling. During long engine idling periods, the engine coolant temperature
may fall below the normal operating range. Incomplete combustion of fuel during the
warm-up period can cause dilution of the oil in the crankcase, formation of lacquer or
gummy deposits on the valves, pistons and rings, and rapid accumulation of sludge
in the engine.
Low Idle Adjustment
DANGER
Before setting the idle, apply the parking
brakes and place the transmission in
neutral. Failure to do so can result in
unexpected vehicle movement and can
cause serious personal injury or death.
