Safety Precautions
CAUTION
Make sure that the combined total
resistance of the battery cable in both
directions between the starter motor
and the battery is within the value
indicated in the Battery Cable
Resistance chart in the Electric Wiring
Section of this manual. The starter
motor will malfunction and fail if the
resistance is higher than the specified
value.

CAUTION
Removing the battery cables or the
battery while the engine is operating
may cause damage to the current limiter
depending on the electrical equipment
being used. This situation could cause
loss of control of output voltage. The
continuous high voltage of 23-24 volts
(for 5000 rpm dynamo) will damage the
current limiter and other electrical
equipment.
0000058en
CAUTION
Reversing the battery cable connections
at the battery or on the engine will
destroy the SCR diode in the current
limiter. This will cause the charging
system to malfunction and may cause
damage to the electrical harnesses.

CAUTION
It is important to perform daily checks.
Periodic maintenance prevents
unexpected downtime, reduces the
number of accidents due to poor
machine performance and helps extend
the life of the engine.

CAUTION
• NEVER attempt to modify the engine’s
design or safety features such as
defeating the engine speed limit
control or the diesel fuel injection
quantity control.
• Modifications may impair the engine’s
safety and performance
characteristics and shorten the
engine’s life. Any alterations to this
engine may void its warranty. Be sure
to use Yanmar genuine replacement
parts.

CAUTION
Identify all parts and their location using
an appropriate method. It is important
that all parts are returned to the same
position during the reassembly process.

CAUTION
Do not rotate the crankshaft with the
injection pump removed.
0000083en
CAUTION
Keep the piston pin parts, piston
assemblies, and connecting rod
assemblies together to be returned to
the same position during the
reassembly process. Label the parts
using an appropriate method.
