SAFETY INSTRUCTIONS
BEFORE SERVICING AND REPAIRING
• Read all instructions and safety instructions in this
manual and on your machine safety decals.
• Clean the work area and machine.
• Park the machine on a firm and level ground, and set
the parking brake.
• Lower the implement to the ground.
• 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.
Q IMPORTANT : Indicates that equipment or property damage could result if instructions are not
followed.
Q NOTE : Gives helpful information.

SAFETY INSTRUCTIONS
SAFETY STARTING
• Do not start the engine by shorting across starter
terminals or bypassing the safety start switch.
• Do not alter or remove any part of machine safety
system.
• Before starting the engine, make sure that all shift
levers are in neutral positions or in disengaged
positions.
• Never start the engine while standing on ground.
Start the engine only from operator’s seat.
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 work under the machine that is supported
solely by a jack. Always support the machine by
safety stands.
• 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.
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 spilled on the engine.

SAFETY INSTRUCTIONS
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.
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.

Engine Serial Number
The engine serial number is an identified number for the engine.
It is marked after the engine model number.
It indicates month and year of manufacture as follows.
• Year of manufacture
• Month of manufacture
e.g. V3300-YA0001
“Y” indicates 2000 and “A” indicates January.
So, YA indicates that the engine was manufactured on January,
2000.

[2] E2 ENGINE
[ex.: Model Name V3300-E2]
The emission controls that have been put into effect in various
countries to prevent air pollution will be stepped up. The time to
enforce the regulations differs depending on the engine output
classifications.
Kubota has been supplying the diesel engines conforming to the
emission regulations in respective countries. Exhaust emissions
regulations shift to the second stage. Kubota executed the
improvement of the engine according to this regulation.
In order to discriminate the engines conforming to Tier 1 / Phase
1 requirements and those conforming to Tier 2 / Phase 2
requirements, we have adopted E2 as a new model name for the
engines conforming Tier 2 / Phase 2 regulations with emission label
(1) or (2).
In the after-sale services for V3300-E2, V3300-TE2 and V3300-
TIE2 series engines, only use the dedicated parts for E2 models and
carry out the maintenance services accordingly.
W1113734
[3] CYLINDER NUMBER
The cylinder numbers of V3300-E2, V3300-TE2 and V3300-TIE2
diesel engine are designated as shown in the figure.
The sequence of cylinder numbers is given as No.1, No.2, No.3
and No.4 starting from the gear case side.
