Maintenance Recommendations
Due to individual applications, it is not possible
to identify all of the factors which can contribute
to severe service operation. Consult your Perkins
dealer or your Perkins distributor for the unique
maintenance that is necessary for the engine.
The operating environment, incorrect operating
procedures, and incorrect maintenance procedures
can be factors which contribute to a severe service
application.
Environmental Factors
Ambient temperatures –
The engine may be
exposed to extended operation in cold environments
or hot environments. Valve components can be
damaged by carbon buildup if the engine is frequently
started and stopped in cold temperatures. Hot intake
air reduces engine performance.
Quality of the air –
The engine may be exposed to
extended operation in an environment that is dirty
or dusty, unless the equipment is cleaned regularly.
Mud, dirt, and dust can encase components.
Maintenance can be dif
fi
cult. The buildup can contain
corrosive chemicals.
Buildup –
Compounds, elements, corrosive
chemicals, and salt can damage some components.
Altitude –
Problems can arise when the engine is
operated at altitudes that are higher than the intended
settings for that application. Necessary adjustments
should be made.
