Engine Damage Prevention
Before Starting the Engine
Before working on a vehicle, set the
parking brakes, place the transmission in
neutral and block the wheels. Failure to
do so can result in unexpected vehicle
movement and can cause serious per-
sonal injury or death.
Inspect engine for potential hazards. Make
sure all protective guards and covers are
properly installed if an engine needs to be
started to make adjustments or checks. To
help prevent an accident by moving parts,
work carefully around them.
DO NOT disable or bypass automatic
alarm/shutoff circuits. They are provided to
prevent personal injury and engine damage.
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.
Make provisions for shutting off the engine
intake air or fuel supply to stop the engine
if there is an overspeed on start-up after
performing repair or maintenance on it.
Always consult the proper Volvo Service
Manual before any repair is attempted.
