Clean parts

Remove mud, straw waste, and grass, wash out dirt, and wipe off the parts with a dry cloth.

Cover the surface where paint peeled off with repairing paint, and apply grease or oil to the area of the body that rusts easily.

Lubricate rotating parts, sliding parts, and wires to prevent rust.

Inspect and clean the air cleaner

The air cleaner having dirty elements cannot provide satisfactory performance-during operation.

How to clean up
Semi-wet air cleaner
  1. Take off the cover from the air cleaner (for details of how to take off, refer to the instruction manual of each machine).
  2. Remove dust. If the air cleaner element is very dirty or lacks adequate oil, wash it with kerosene, squeeze it well, soak it in engine oil, squeeze it firmly, and then attach it to the air cleaner.
  3. Wipe clean the inside of the cover as well, and return the cover to the machine.
Oil bath air cleaner
  1. If the cleaner lacks adequate oil, supply oil up to the oil level line of the oil cup.
  2. If the oil is dirty, take off the oil cup and element, wash them with kerosene, and attach the element to the machine. Pour engine oil in the oil cup up to the oil level line, and then reset the cup too.
Inspect and clean the fuel system

Clean the cup of fuel strainer if water or dust accumulates in it.

How to clean
  1. Turn the fuel cock to “close.”
  2. Take off the cup, packing, and net.
  3. Wash clean them with kerosene, and attach them.

Confirm that there is no fuel leakage caused by deterioration or a crack of the fuel hose.

Inspect and clean the spark plug

The spark plug also may not work adequately, for example, the engine does not start smoothly if the plug is used for a long time and carbon (soot) builds up on the electrode.

How to clean
  1. Take off the plug cap, and then the spark plug with the box wrench attached to the machine.
  2. Remove carbon (soot) from the spark plug.
  3. Adjust the electrode to have a space of 0.7 mm.
  4. If the plug is worn or damaged too badly to be adjusted, replace it with new one.
  5. Attach the spark plug.
Inspect and change the engine oil

Change the engine oil on a regular basis since it deteriorates after a long time use.
Change it after 30 hours of use for the first time, and after every 50 hours of use from the second time.

How to change
  1. Stop the machine so that the engine is level with the ground.
  2. Take off the fuel plug and drain plug, then drain the oil.
  3. Once the oil is fully drained, close the drain plug firmly, and supply new oil through the fuel filler hole up to the “upper limit” of the oil gauge.

*The oil you will be using should be Mitsubishi genuine oil

Inspect the quantity and change the transmission oil

Take off the fuel plug, and check if the oil quantity meets the specified level.

If it is less than the specified level, supply the oil until it reaches the level.

Change the transmission oil on a designated periodic interval.

Sufficiently tighten loose wires, belts, and bolts

Each part is properly adjusted when the machine is shipped out; however, readjust the part if wear or losing of elasticity occurs after use or replace it if the condition exceeds the limit of wear to use it appropriately.

As for places to be checked, and details of adjustments, please refer to and follow the instruction manual.

Inspect the tires

Check for a crack or damage to the tires, and adjust the air pressure.

If the tires are seriously damaged, replace them.

Long-term storage

If the machine is not to be used for a month or longer, surely remove gasoline from it. With time, gasoline will deteriorate, which may clog the carburetor and disturb the engine, or lead to a poor driving, so make a point of trying to remove gasoline if the machine will be stored for a long time.

How to remove fuel
  1. Remove the fuel from the fuel tank with a fuel oil pump, and drain the remnant by taking off the fuel strainer cup.
  2. Pull the pull drain (or loose the drain) of carburetor, remove the fuel from the carburetor completely.
  3. After the removal, attach the fuel strainer cup, and shut off the fuel cock. At the same time, restore the parts you have loosened to the original state.
Wheel-lock the tires

For the storage, wheel lock the tires on a level place to prevent the machine from moving.

A low air pressure might accelerate the deterioration of the tires, so if such is a case, supply the air up to the specified level.

When putting a seat cover

When putting a seat cover on the machine, do so after the engine sufficiently cooling down.

If covering while the engine is still hot, it might be the cause of a fire.

Visit a distributor of agricultural machinery if you are interested in purchasing a mini-cultivator.

The distributor staffed by agricultural mechanics will provide good after-sales service, such as maintenance and replacement of consumables.

You can also seek or obtain various advice or information there, so we recommend that you purchase the machine in a distributor of agricultural machinery.
