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 influe nce
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 regula tions when disp osing
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.

[ex.: Model Name V3300-E2]
The emission controls that have be en 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 emissio n label
(1) or (2).
In the after-sale services for V3300-E2, V3300-TE2 and V3300TIE2 series engines, only use the dedicated parts for E2 models a nd
carry out the maintenance services accordingly.

3. GENERAL PRECAUTIONS
• During disassembly, carefully arrange removed parts in a clean
area to prevent confusion later. Screws, bolts and nuts should b e
installed in their original position to prevent reassembly errors.
• When special tools are required, use KUBOTA genuine special
tools. Special tools which are not frequently used should be
made according to the drawings provide d.
• Before disassembling or servicing electrical wires, always
disconnect the ground cable from the battery first.
• Remove oil and dirt from parts before measuring.
• Use only KUBOTA genuine parts for parts replacement to
maintain machine performance and to assure safety.
• Gaskets and O-rings must be replaced during reassembly.
Apply grease to new O-rings or oil seals before assembling.
See the figure left side.
• When reassembling external snap rings or internal snap rings,
they must be positioned so that sharp edge faces against the
direction from which a force is applied. See the figure left side.
• When inserting spring pins, their splits must face the direction
from which a force is applied. See the figure left side.
• To prevent damage to the hydraulic syst em, use only specified
fluid or equivalent.

• Engine Oil : Oil used in the engine should have an Americ an Petroleum Institute (API) service classif ication
and Proper SAE Engine Oil according to the ambient temperature as shown above.
Do not mix different brands together.
• With the emission control now in effect, the CF-4 and CG-4 lubricating oils have been developed for use
of a low-sulfur fuel on-road vehicle engines. When an off-road vehicle engine runs on a high-sulfur fuel,
it is advisable to employ the CF, CD or CE lubricating oil with a high total base number. If t he CF-4 or CG4 lubricating oil is used with a high-sulfur fuel, change the lubricating oil at shorter intervals.
• Lubricating oil recommended when a low-sulfur or high-sulfur fuel is employed.

• Transmission Oil : The oil used to lubricate the transmission is also used as hydraulic fluid. To insure
proper operation of the hydraulic system and complete lubrica tion of the transmission, it is important that
a multi-grade transmission fluid be used in t his system. We recommend the use of KUBOTA SUPER UDT
fluid for optimum protection and performance.
Do not mix different brands together.
• Indicated capacity of water and oil are manufacture’s estimate.
