Cooling Fan And Belt; Waste Materials; Precautions For The Use Of The Synthetic Biodegradable Oil Type Hees - Komatsu PC27R-8 Operation & Maintenance Manual

2.8.18 COOLING FAN AND BELT

Be careful to the revolving parts and do not allow anyone to
get too close to these parts, since clothes or parts of the body
may get caught into them.
If hands, clothes, or tools touch the fan blades or the belt, they
may be cut, torn or seriously damaged; for this reason, avoid
touching the revolving parts.

2.8.19 WASTE MATERIALS

Do not dispose of used oil in the sewer system, rivers, etc.
Always put used oil in containers. Never drain the oil directly
onto the ground.
Keep to the laws and regulations in force when disposing of
harmful substances such as oil, fuel, solvents, used filters and
batteries.
2.8.20 PRECAUTIONS FOR THE USE OF THE SYNTHETIC BIODEGRADA-
BLE OIL TYPE HEES
It is not possible to mix the synthetic biodegradable oil type HEES with ordinary hydraulic oils, since when the
temperature increases insoluble compounds are generated, which are deposited on the filters and clog them
(the maximum concentration of ordinary oil cannot exceed 1% of the total quantity of oil).
The biodegradable oil can be used only in the hydraulic system; it cannot be used for the endothermic engine,
the transmissions, the braking system, etc.
Before introducing the synthetic biodegradable oil in the hydraulic system, empty the system completely, dis-
connecting the cylinders and all the parts that may contain ordinary oil, and replace the drain filter with a new
one.
Start the engine and let it idle without using the work equipment , wait until the oil reaches a temperature of at
least 40°C, then start moving the equipment, so that all the parts of the system are filled with oil. Stop the en-
gine and check the oil level (see "4.7.3.e CHECKING THE HYDRAULIC SYSTEM OIL LEVEL").
