Start the engine from the operator's compartment or
from the engine start switch.
Always start the engine according to the procedure
that is described in this Operation and Maintenance
Manual, “Engine Starting” topic (Operation Section).
Knowing the correct procedure will help to prevent
major damage to the engine components. Knowing
the procedure will also help to prevent personal
injury.
To ensure that the jacket water heater (if equipped)
and/or the lube oil heater (if equipped) is working
properly, check the water temperature gauge and the
oil temperature gauge during the heater operation.
Engine exhaust contains products of combustion that
can be harmful to your health. Always start the
engine and operate the engine in a well ventilated
area. If the engine is started in an enclosed area,
vent the engine exhaust to the outside.
Ether
Ether is poisonous and flammable.
Do not inhale ether, and do not allow ether to contact
the skin. Personal injury could result.
Do not smoke while ether cylinders are changed.
Use ether in well ventilated areas.
Use ether with care in order to avoid fires.
Keep ether cylinders out of the reach of unauthorized
persons.
Store ether cylinders in authorized storage areas
only.
Do not store ether cylinders in direct sunlight or at
temperatures above 49 °C (120 °F).
Discard the ether cylinders in a safe place. Do not
puncture the ether cylinders. Do not burn the ether
cylinders.

Engine Stopping
SMCS Code: 1000
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. This may be
accomplished by shutting off the fuel supply to the
engine and/or shutting off the air supply to the
engine.
To stop an electronically controlled engine, cut the
power to the engine.

Electrical System
SMCS Code: 1000; 1400
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.
If the engine must be started by an external electrical
source, then always connect the positive jump start
cable “+” to the positive terminal “+” of the battery.
To help prevent sparks from igniting combustible
gases that are produced by some batteries, the
negative “−” jump start cable should be connected
last from the external power source to the negative
“−” terminal of the starting motor. If the starting motor
is not equipped with a negative “−” terminal, connect
the jump start cable to the engine block.
Grounding Practices
Proper grounding for the engine electrical system is
necessary for proper engine performance and
reliability. Improper grounding will result in
uncontrolled electrical circuit paths and unreliable
electrical circuit paths.
Uncontrolled engine electrical circuit paths can result
in damage to the following components: main
bearings, crankshaft bearing journal surfaces and
aluminum components. All grounds should be tight
and free of corrosion.
The alternator and the starting motor must be
grounded to the negative “-” battery terminal.
For engines that have an alternator that is grounded
to an engine component, a ground strap must be
used. The ground strap must be connected to the
component and to the negative “-” battery terminal.
The component must be electrically isolated from the
engine.
A ground plate with a direct path to the negative
battery terminal “-” can be used as a common ground
point for the components of one engine system.
