    It is the new machine's specification ex-factory. It is mainly based on quality standard, drawings, or actual measurements conducted by KUBOTA. This value is used to judge if a machine has a problem when testing and troubleshooting. Still, normal wear-related deterioration of the service specification must be taken in account based on machine's operating hours, application or maintenance.
  • Service limits:
    Specification which corresponds to the recommended performance limit taking in account long term wear. The machine is supposed to have insufficient performance for proper and/or safe work and a repair/overhaul would be required.

All of the illustrations, photographs, specifications and other information in this manual were created based on the latest model at the time of publication.

In the interest of work safety

Precautions before working on the equipment

• Read all the general and safety instructions in this manual, as well as the decals on your equipment.
• Always stop the engine whenever you leave the driver's seat to inspect or clean the equipment or its devices, or to inspect or adjust parts.
• Choose a safe spot for inspecting the equipment-on flat, hard ground.
• When performing maintenance on the equipment, hang the[DO NOT OPERATE] sign where it will be obvious from and around the driver's seat.
• When performing maintenance or repairs, always lower attachments to the ground, stop the engine and set the brake.
• When performing maintenance on the equipment, always disconnect the negative battery cable.
• Before using tools, make sure you understand how to use them correctly and use tools in good condition and of the right size for the job.

Be ready for an emergency

• Keep a first-aid kit and fire extinguisher close at hand so you can use it when needed.
• Keep emergency contact information for doctors, hospitals and ERs handy.
• Wear clothes appropriate for working on equipment. Do not wear loose-fitting clothes as they may catch on the equipment's controls.
• When working on the equipment, use all safety gear, such as a helmet, safety glasses and shoes, that are required by law or regulation.
• Never perform maintenance while drowsy or under the influence of alcohol or drugs.

Precautions before working on the equipment

• When performing the work, place the equipment on level and firm ground in a location with no obstacles or hazardous materials in the vicinity.
• If performing the work indoors, ensure that the work area is well ventilated.
• Do not allow unrelated persons to be in the vicinity of the equipment.
• Before servicing the equipment, clean it off so there is no mud, debris, oil or the like sticking to it.
• When getting in or out of the equipment, always use the 3-point support with hands and feet.

Starting the machine safely

• Before starting the engine, always sit in the driver's seat and make sure the area is safe and clear.
• Never start the engine from anywhere but thedriver's seat.
• Always check and make sure control lever(s) are not engaged before starting the engine.
• Never start the engine by hot-wiring the starter circuit. This is not only dangerous, but may damage the equipment.
• Always secure the engine cover, bonnet, etc. when starting up the equipment.
• Never approach rotating or moving parts. Moreover, do not leave tools, rags, etc., inside the equipment.
• The engine, muffler, radiator, hydraulic equipment, etc., remain hot even after the engine is stopped, so do not touch these parts.
• The engine's coolant, oil, hydraulic oil, etc. remain hot and are under high pressure even after the engine is stopped, so wait until they cool sufficiently before removing their caps or plugs.
• Check and make sure the temperature of the coolant has dropped sufficiently, and release pressure before opening the radiator cap.
• When removing parts such as hydraulic equipment after stopping the engine, release all residual pressure from the hydraulic circuit beforehand.
• Please note that when releasing residual pressure, the equipment itself and/or implements may move without warning, so be very careful when releasing the pressure.
• So when checking for oil leaks, always wear safety glasses and gloves and use a piece of cardboard or a wood block to shield yourself from oil.

Keep away from fire

• Keep the fuel and oil away from fire (welding, grinding, smoking, etc.).
• If fuel is spilled, wipe it all up immediately.
• Always wear safety glasses and gloves when handling the battery.
• The gas generated from a battery is flammable, therefore, keep it away from fire (welding, grinding, smoking, etc.).
• When disconnecting the battery, always disconnect the negative cable first.
• When connecting the battery, always connect the positive cable first.

Processing waste liquid

• Do not dispose of hydraulic oil, engine oil, coolant, electrolyte, etc., in the ground, drains, rivers, ponds, lakes, etc.
• Dispose of hydraulic oil, engine oil, coolant, electrolyte, etc., in accordance with the relevant environmental protection standards.

Safety labels

Affixing positions of safety labels
Ensure that you have read and understood the safety labels before operating the equipment.

Maintenance of safety labels

• Always keep the labels clean and ensure they do not become scratched.
• If a label is dirty, wash it with soapy water and wipe with a soft cloth.
• Do not spray labels directly with a high-pressure cleaner.
• Replace damaged or lost labels with a new label.
• When affixing a new label, wipe the affixing surface so that it is free of dirt, and affix the label in its original position after the surface dries.
• When replacing a part that has a label affixed, replace the label at the same time.

2. Use a press and insertion jig to press-fit the OilSeal.

NOTE

• If you do not have a press, place the jig against the seal and lightly tap it evenly so that is fitted flat.

3. Press the seal until it is seated in the boss.

4. Apply grease to the lip of the Oil Seal. If the seal has a dust lip, fill the gap between the lips with grease.

3. Lightly apply a sealing oil on the sliding surface ofthe floating seal.
4. Assemble so that the sliding surface of the floatingseal, the O-ring, and housing are all parallel.
5. After assembly, idle 2 to 3 times to allow a film of oilto form on the sliding surface and then check that the seal face slides smoothly along the film.
