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.

0000080en

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.
