SAFETY INSTRUCTIONS

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 instruct ions and safe ty regulations before y ou attempt to re p air 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.

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 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 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 re pair 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.

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 fir st and connect it last.

• Battery gas can explode. Keep sparks and open flame away from the top of battery, espe cially when charging the battery.

• Make sure that no fuel has been spilled on 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 regula tions when disp osing of oil, fuel, coolant, electrolyte and other harmful waste.

[2] E3B ENGINE

[Example : Engine Model Name D1803-M-E3B-XXXX or D1803-M-DI-E3B-XXXX]

The emission controls previously implemented in various countries to prevent air pollution will be stepped up as Non-Road Emission Standards continue to change. The timing or applicable da te of the specific Non-Road Emission regulations depends on the engine output classification.

Over the past several years, Kubota has been supplying diesel engines that comply with regulations in the respective countries affected by Non-Road Emission regulations. For Kubota Engines, E3B will be the designation that identifies engine models affected by the next emission phase (See the table below).

When servicing or repairing ###-E3B series engines, use only replacement parts for that specific E3B engine, designated by the appropriate E3B Kubota Parts List and perform all maintenance services listed in the appropriate Kubota Operator's Manual or in the appropriate E3B Kubota Workshop Manual. Use of incorrect replacement parts or replacement parts from other emission level engines (for example: E2 B engines), may result in emission leve ls out of compliance with the original E3B design and EPA or other applica ble regulations.Please r efer to the emission label located on the engine head cover to identify Output classification and Emission Control Information. E3B engines are identified with "ET" at the end of the Model designation, on the US EPA label. Please note : E3B is not marked on the engine.

Category (1) Engine output classification EU regulation

K From 19 to less than 37 kW STAGE ΙΙΙA J From 37 to less than 75 kW STAGE ΙΙΙA

(1) EU regulation engine output classification category (2) “E3B” engines are identified with “ET” at the end of the Model designation, on

the US EPA label. “E3B” designates Tier 3 and some Interim Tier 4 / Tier 4 models, depending on engine output classification.

From 19 to less than 56 kW Interim Tier 4 From 56 to less than 75 kW Tier 3 From 75 to less than 130 kW Tier 3

2. GENERAL PRECAUTIONS

• During disassembly, carefully arrange removed parts in a clean area to prevent confusion later. Screws, bolts and nuts should b e replaced 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 live wires, make sure to always disconnect the grounding cable from the battery first.

• Remove oil and dirt from parts before measuring.

• Use only KUBOTA genuine parts for parts replacement to maintain engine performance and to ensure safety.

• Gaskets and O-rings must be replaced during reassembly. Apply grease to new O-rings or oil seals before assembling.

• When reassembling external or internal snap ring s, position them so that the sharp edge faces against the direction from which force is applied.

• Be sure to perform run-in the serviced or reassembled engine. Do not attempt to give heavy load at once, or serious damage may result to the engine.
