2. CARRIER HYDRAULIC OIL
2.1 REQUIREMENTS FOR HYDRAULIC OIL
GENERAL REQUIREMENTS
In general, the hydraulic oil originally intended for the carrier can be used with this
product. However, since working with the product heats the oil more than with the
usual excavation work, the temperature of the oil must be monitored.
If the temperature of the hydraulic oil exceeds 80 °C (176 °F), an auxiliary oil cooler
is needed. The oil viscosity must be between 1000-20 cSt while the product is being
used.
When the product is used continuously, the temperature of the hydraulic oil
normalizes at a certain level depending on conditions and on the carrier. The
temperature in the tank must not exceed the maximum allowed.
The product must not be started if the ambient temperature is below freezing and
the oil is very thick. The machine must be moved to bring the oil temperature above
0 °C (32 °F) before working can start (viscosity 1000 cSt or 131 °E).
