These engines are equipped with a glow plug starting
aid in each individual cylinder that heats the intake air
in order to improve starting. Some Perkins engines
may have a cold starting system that is controlled by
the ECM that allows a controlled flow of ether into the
engine. The ECM will disconnect the glow plugs
before the ether is introduced. This system would be
installed at the factory.
Engine Stopping
Stop the engine according to the procedure in the
Operation and Maintenance Manual, "Engine
Stopping (Operation Section)" in order to avoid
overheating of the engine and accelerated wear of
the engine components.
Use the Emergency Stop Button (if equipped) ONLY
in an emergency situation. Do not use the Emergency
Stop Button for normal engine stopping. After an
emergency stop, DO NOT start the engine until the
problem that caused the emergency stop has been
corrected.
Stop the engine if an overspeed condition occurs
during the initial start-up of a new engine or an engine
that has been overhauled.
To stop an electronically controlled engine, cut the
power to the engine and/or shutting off the air supply
to the engine.
Electrical System
Never disconnect any charging unit circuit or battery
circuit cable from the battery when the charging unit is
operating. A spark can cause the combustible gases
that are produced by some batteries to ignite.
To help prevent sparks from igniting combustible
gases that are produced by some batteries, the
negative "−" cable should be connected last from the
external power source to the primary position for
grounding.
Check the electrical wires daily for wires that are
loose or frayed. Tighten all loose electrical
connections before the engine is started. Repair all
frayed electrical wires before the engine is started.
See the Operation and Maintenance Manual for
specific starting instructions.
