TO THE READER
This Workshop Manual has been prepared to provide servicing personnel with
information on the mechanism, service and maintenance of 03-M-E3B, 03-M-DI-E3B
and 03-M-E3BG series. It is divided into three parts, “General”, “Mechanism” and
“Servicing”.
QGeneral
Information on the engine identification, the general precautions, maintenance check
list, check and maintenance and special tools are described.
QMechanism
Information on the construction and function are included. This part should be
understood before proceeding with troubleshooting, disassembling and servicing.
Refer to Diesel Engine Mechanism Workshop Manual (Code No. 9Y021-01875) for
the one which has not been described to this workshop manual.
QServicing
Information on the troubleshooting, servicing specification lists, tightening torque,
checking and adjusting, disassembling and assembling, and servicing which cover
procedures, precautions, factory specifications and allowable limits.
All information illustrations and specifications contained in this manual are based on
the latest product information available at the time of publication.
The right is reserved to make changes in all information at any time without notice.
Due to covering many models of this manual, information or picture being used, have
not been specified as one model.

03-M-E3B, 03-M-DI-E3B, 03-M-E3BG WSM SAFETY INSTRUCTIONS
SAFETY INSTRUCTIONS
BEFORE SERVICING AND REPAIRING
• Read all instructions and safety instructions in this
manual and on your engine safety decals.
• Clean the work area and engine.
• Park the machine on a firm and level ground.
• Allow the engine to cool before proceeding.
• Stop the engine, and remove the key.
• Disconnect the battery negative cable.
• Hang a “DO NOT OPERATE” tag in operator
station.
SAFETY FIRST
This symbol, the industry’s “Safety Alert Symbol”, is used throughout this manual and on labels on
the machine itself to warn of the possibility of personal injury. Read these instructions carefully.
It is essential that you read the instructions and safety regulations before you attempt to repair or use
this unit.
DANGER : Indicates an imminently hazardous situation which, if not avoided, will result in
death or serious injury.
WARNING : Indicates a potentially hazardous situation which, if not avoided, could result in
death or serious injury.
CAUTION : Indicates a potentially hazardous situation which, if not avoided, may result in
minor or moderate injury.
QIMPORTANT : Indicates that equipment or property damage could result if instructions are not
followed.
QNOTE : Gives helpful information.

03-M-E3B, 03-M-DI-E3B, 03-M-E3BG WSM SAFETY INSTRUCTIONS
SAFETY STARTING
• Do not start the engine by shorting across starter
terminals or bypassing the safety start switch.
• Unauthorized modifications to the engine may impair
the function and / or safety and affect engine life.
SAFETY WORKING
• Do not work on the machine while under the influence
of alcohol, medication, or other substances or while
fatigued.
• Wear close fitting clothing and safety equipment
appropriate to the job.
• Use tools appropriate to the work. Makeshift tools,
parts, and procedures are not recommended.
• When servicing is performed together by two or more
persons, take care to perform all work safely.
• Do not touch the rotating or hot parts while the engine
is running.
• Never remove the radiator cap while the engine is
running, or immediately after stopping. Otherwise, hot
water will spout out from radiator. Only remove
radiator cap when cool enough to touch with bare
hands. Slowly loosen the cap to first stop to relieve
pressure before removing completely.
• Escaping fluid (fuel or hydraulic oil) under pressure
can penetrate the skin causing serious injury. Relieve
pressure before disconnecting hydraulic or fuel lines.
Tighten all connections before applying pressure.
• Wear a suitable hearing protective device such as
earmuffs or earplugs to protect against objectionable
or uncomfortable loud noises.
• Do not open high-pressure fuel system.
High-pressure fluid remaining in fuel lines can cause
serious injury. Do not disconnect or attempt to repair
fuel lines, sensors, or any other components between
the high-pressure fuel pump and injectors on engines
with high pressure common rail fuel system.
• High voltage exceeding 100 V is generated in the
ECU, and is applied to the injector.
Pay sufficient caution to electric shock when
performing work activities.

03-M-E3B, 03-M-DI-E3B, 03-M-E3BG WSM SAFETY INSTRUCTIONS
AVOID FIRES
• Fuel is extremely flammable and explosive under
certain conditions. Do not smoke or allow flames or
sparks in your working area.
• To avoid sparks from an accidental short circuit,
always disconnect the battery negative cable first and
connect it last.
• Battery gas can explode. Keep sparks and open
flame away from the top of battery, especially when
charging the battery.
• Make sure that no fuel has been spilledon the engine.
VENTILATE WORK AREA
• If the engine must be running to do some work, make
sure the area is well ventilated. Never run the engine
in a closed area. The exhaust gas contains poisonous
carbon monoxide.
PREVENT ACID BURNS
• Sulfuric acid in battery electrolyte is poisonous. It is
strong enough to burn skin, clothing and cause
blindness if splashed into eyes. Keep electrolyte
away from eyes, hands and clothing. If you spill
electrolyte on yourself, flush with water, and get
medical attention immediately.
DISPOSE OF FLUIDS PROPERLY
• Do not pour fluids into the ground, down a drain, or
into a stream, pond, or lake. Observe relevant
environmental protection regulations when disposing
of oil, fuel, coolant, electrolyte and other harmful
waste.

03-M-E3B, 03-M-DI-E3B, 03-M-E3BG WSM SAFETY INSTRUCTIONS
PREPARE FOR EMERGENCIES
• Keep a first aid kit and fire extinguisher handy at all
times.
• Keep emergency numbers for doctors, ambulance
service, hospital and fire department near your
telephone.
