5.2. Maintenance Summary
5.2.1. Lubricant

Use oil of the grade and temperature specified in the "Oil Selection Table" in this
manual. Change the oil within the specified time, even if it is not dirty.

Take care to prevent contaminants (water, metal particles, dust, etc.) from
entering the lubricant. Most problems with machines are caused by the
introduction of impurities.

Do not mix different grades of lubricants together.

Do add the required amount of oil. Too much oil or too little oil can cause
malfunction.

When changing oil, be sure to replace the associated filter element, especially
when replacing the oil filter element, add fresh, clean and compliant oil to the
new element before installing it.
5.2.2. Fuel

When storing or adding fuel, take special care not to allow impurities to enter.

Make sure to use the fuel specified in the "Fuel Selection Table" in this manual.
When using fuel, use it according to the ambient temperature, otherwise it will
easily solidify at low temperatures (especially below -15°C (5°F)). Therefore, it
is necessary to replace the fuel with one that matches the ambient temperature.

To prevent moisture in the air from condensing in the fuel tank and forming
water, fill the fuel tank at the end of each day's work.

Before starting the engine, or 10 minutes after filling the fuel, drain the sediment
and water from the tank.

If the engine has run out of fuel, or if the filter element has been replaced, the air
in the fuel line must be drained.
5.2.3. Grease

Grease is used to prevent twisting and noise at the joints.
