Engine Starting
Do not use aerosol types of starting aids such as
ether. Such use could result in an explosion and
personal injury.
Engine exhaust contains products of combustion
which may be harmful to your health. Always
start and operate the engine in a well ventilated
area and, if in an enclosed area, vent the exhaust
to the outside.
If a warning tag is attached to the engine start switch
or to the controls, DO NOT start the engine or move
the controls. Consult with the person that attached
the warning tag before the engine is started.
All protective guards and all protective covers must
be installed if the engine must be started to perform
service procedures. To help prevent an accident that
is caused by parts in rotation, work around the parts
carefully.
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 the Operation and Maintenance
Manual, “Engine Starting” topic in the 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) is
working correctly, check the water temperature
gauge and/or the oil temperature gauge during the
heater operation.
Note: The engine may be equipped with a device for
cold starting. If the engine will be operated in very
cold conditions, then an extra cold starting aid may
be required. Normally, the engine will be equipped
with the correct type of starting aid for your region of
operation.

Engine Stopping
Do not stop the engine immediately after the engine
has been operated under load. Abrupt stopping of the
engine can cause overheating and accelerated wear
of engine components. Allow the engine to run for 5
minutes before engine shutdown. Running the
engine allows hot areas of the engine to cool
gradually.

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 “−” 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.
Check the electrical wires daily for wires that are
loose or frayed. Tighten all loose electrical wires
before the engine is started. Repair all frayed
electrical wires before the engine is started. Refer to
the “Engine Starting” section of this Operation and
Maintenance Manual for specific starting instructions.
Grounding Practices
Proper grounding for the engine electrical system is
necessary for optimum engine performance and
reliability. Improper grounding will result in
uncontrolled electrical circuit paths and in unreliable
electrical circuit paths.
Uncontrolled electrical circuit paths can result in
damage to main bearings, to crankshaft bearing
journal surfaces, and to aluminum components.
Engines that are installed without engine-to-frame
ground straps can be damaged by electrical
discharge.
To ensure that the engine and the engine electrical
systems function properly, an engine-to-frame
ground strap with a direct path to the battery must be
used. This path may be provided by way of a starting
motor ground, a starting motor ground to the frame,
or a direct engine ground to the frame.
