Engine Overspeed
This vehicle is equipped with a diesel en-
gine 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 ex-
haust system, and cause an explosion and
fire.
If the vehicle is in an area where hydrocar-
bon 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 in-
take 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 explo-
sion can occur.
Do not use ether or similar starting aids
in a Volvo or other engine with . The
Volvo engine is equipped with a pre-
heater. Introduction of ether or other
combustible material in the intake mani-
fold could cause a fire or explosion,
resulting in severe property damage, se-
vere personal injury or death.
