Use of biodegradable oils
When you use biodegradable oil, please refer to following:
• There are two types of biodegradable oil available: vegetable-based and synthetic-based. We recommend using
synthetic oils, because vegetable ones have a maximum operating temperature of 80 °C (176 °F). For this reason,
the degradation of vegetable-based oil occurs more rapidly, and they have a reduced service life.
• Do not mix bio-oil with original factory-filled mineral oil; in case it is necessary to use bio-oil, flush the hydraulic
system that was filled with bio-oil three times.
• If you use bio-oil, the performance of the rotation brake and that of the parking/travel brake will be reduced, because
of the lower friction factor of bio-oil compared to that of mineral oil.
• For further information about the type of biodegradable lubricant and the relevant specifications for use and main-
tenance, please refer to chapter ACCESSORIES.
Use of coolant
• There are two types of coolant depending on the corrosion inhibitors base: ORGANIC-base and INORGANIC base.
• Mini excavators is ORGANIC-base type factory filled.
• Both type can be used, BUT THEY CANNOT BE MIXED. Flush the cooling system before change coolant type.
