Kubota Diesel Engine Z722-E

WARNING! To avoid personal injury or death: Be sure to stop the engine and remove the key before checking the belt tension. Be sure to reinstall the detached safety shield after maintenance or checking.

Applied moderate thumb pressure to belt between the pulleys

Belt tension in the proper range

IMPORTANT: If belt is loosen or damaged and the fan is damaged, it could result in overheats or insufficient charging. Correct or replace belt.

Measure tension with a sonic tension meter

Measurement done properly according to the operation manual of the device being used

Measurement done immediately after installing the belt without rotating the pulleys

Initial Oil Change after 50hours. WARNING! To avoid personal injury or death: Be sure to stop the engine before draining engine oil and changing the oil filter cartridge.

When draining engine oil, place some container underneath the engine and dispose it according to local regulations.

Do not drain oil after running the engine. Allow engine to cool down sufficiently. Oil can be hot and cause burns

2. Remove the drain plug at the bottom of the engine, and drain all the old oil. Drain oil easier and completely while the engine is hot.

3. When letting out the oil, remove the filler plug too. With the filler plug still in place, it would be difficult to discharge the oil completely.

4. Add new engine oil up to the upper limit of the oil level gauge. Be careful not to add oil above the upper limit of the oil level gauge.

Replacing the oil filter cartridge

1. Replace the oil filter cartridge.

WARNING! To avoid personal injury or death: Be sure to stop the engine before checking and changing the engine oil and the oil filter cartridge.

Do not touch muffler or exhaust pipes while they are hot; Severe burns could result.

Always stop the engine and allow it to cool before conducting inspections, maintenance, or for a cleaning procedure.

Contact with engine oil can damage your skin. Put on gloves when using engine oil. If you come in contact with engine oil, wash it off immediately.

NOTE! Be sure to inspect the engine, locating it on a horizontal place. If placed on gradients accurately, oil quantity may not be measured.

Be sure to keep the oil level between upper and lower limits of the oil gauge. Too much oil may cause a drop in output or excessive blow-by gas.

On the closed breather type engine in which mist is sucked through port, too much oil may cause oil hammer.

While too little oil, may seize the engine's rotating and sliding parts. (The closed breather is an option.)

Check the engine oil level before starting or more than 5 minutes after stopping the engine.

WARNING! To avoid personal injury or death: Check or replace the fuel pipes after stopping the engine. Broken fuel pipes can cause fires.

If the clamp band is loose, apply oil to the screw of the band, and tighten the band securely.

Are the fuel pipes, made of rubber, worn out?

If the fuel pipes, made of rubber, become worn out, replace them and clamp bands every 2 years.

Are the fuel pipes and clamp bands found worn or damaged before 2 years' pass?

If the fuel pipes and clamp bands are found worn or damaged before 2 years' pass, replace or repair them at once.

After replacement of the pipes and bands, air-bleed the fuel system.

Important: When the fuel pipes are not installed, plug them at both ends with clean cloth or paper to prevent dirt from entering. Dirt in the pipes can cause fuel injection pump malfunction.

WARNING! To avoid personal injury or death: Be careful not to let the battery electrolyte contact your body or clothing.

Wear eye protection and rubber gloves, since the diluted sulfuric acid solution burns skin and eats holes in clothing.; Should this occur, immediately wash it off with running water and get medical attention.

DANGER! Do not use or charge the battery if its fluid level stands below the LOWER (lower limit level) mark.

Otherwise, the battery component parts may deteriorate earlier than expected, which may shorten the battery's service life or cause an explosion. Immediately, add distilled water until the battery's fluid level is between the UPPER and LOWER levels.

WARNING! To avoid personal injury or death: When the battery is being activated, hydrogen and oxygen gases in the battery are extremely explosive.

Keep open sparks and flames away from the battery at all times, especially when charging the battery.

When charging the battery, remove the battery vent plugs. When disconnecting the cable from the battery, start with the negative terminal, and when connecting them, start with the positive terminal first.; DO NOT check the battery charge by placing a metal object across the terminals. Use a voltmeter or hydrometer.

1. Make sure each electrolyte level is to the bottom of vent wells, if necessary, add only distilled water in a well-ventilated place.

2. To slow charge the battery, connect the charger positive terminal to the battery positive terminal, and negative to the negative.
