SY115C9/135C/155H Crawler Hydraulic Excavator
Note:
* Capacity of engine oil pan on SY135C8M is 15 L (3.98 US gal).
Always use diesel oil as the fuel.
To ensure favorable consumption and exhaust of the fuel, the engine installed to your machine
uses high-pressure oil injection unit with mechanical control. The unit contains high-precision
components that require high-quality lubrication. Therefore, the use of low-viscosity fuel with low
lubricating capability will considerably reduce the service life of the unit.
5.4.1 Fluid capacities
Recommended brands and quality of recommended products besides Sany genuine oils
Consult your Sany distributor before using any oils other than those recommended by Sany.
Note 1: The HTHS (high-temperature high-shear viscosity at 150°C) required by ASTM D4741
must be equal to or more than 3.5 mPa-S. Sany strongly recommend the use of engine
oil 15W-40.
Note 2: Coolant
1) The coolant is also an important
fl
uid against corrosion and freezing.
Antifreezing coolant is also necessary in regions where freezing prevention is unnecessary.
Sany machines are pre
fi
lled with TEEC-L35 antifreeze, which has excellent performance in
anticorrosion, antifreezing and cooling.
2) For more information on diluting TEEC-L35 antifreeze with water

.
3) The proper concentration of coolant must be kept in order to ensure the coolant's performance
against corrosion.
