2.8.29 PRECAUTIONS TO BE TAKEN WHEN HANDLING TECHNOPOLY-
MERS AND ELASTOMERS
DANGER
q
Some components of the machine contain polymeric and elastomeric materials (Viton sealing rings, Te-
flon rings, piston rings made of fluoroelastomers, electric cable insulating materials, etc.).
At ambient temperature and up to approximately 200°C these materials can be handled without taking
special precautions, since they are completely inert.
If these materials are burnt, they send out gas and become highly toxic.
Once they have cooled down, these materials must be collected in tight bags using heavy, waterproof
gloves; then, gloves and materials must be disposed of according to the current regulations in force.
The contaminated parts of the machine must be washed with highly alkaline detergents and then with a
solution of water and detergent.
q
Avoid burning gaskets, eletric cables, sealing rings.
q
Dispose of elastomeric and polymeric waste according to the
regulations in force.
q
Do not touch any burnt elastomeric or polymeric waste and in
case of accidental burning avoid inhaling the toxic gases pro-
duced.
q
In case of contact with the skin, immediately rinse with a solu-
tion made of water and an alkaline detergent for about 30 min-
utes and then contact a poisoning treatment center without
delay.
2.8.30 PRECAUTIONS TO BE TAKEN WHEN USING SYNTHETIC BIODE-
GRADABLE OIL TYPE HEES
q
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 deposit on the filters and clog them (the max-
imum concentration of ordinary oil must not exceed 1% of the total quantity of oil).
q
Biodegradable oil can be used only in the hydraulic system; it cannot be used for the engine, the transmissions,
the braking system, etc.
q
Before introducing biodegradable oil in the hydraulic system, drain the system completely, disconnecting the cyl-
inders and all the parts that may contain traditional oil, then change the drain filter with a new one.
Start the engine and let it idle before using the equipment, wait for the engine temperature to reach at least 40°C,
then start moving the equipment to fill all the circuits with oil. Stop the engine and check the oil level (see "3.3.1.2
CHECKS TO BE CARRIED OUT BEFORE STARTING THE ENGINE" - " CHECKING THE OIL LEVEL IN THE
HYDRAULIC TANK AND TOPPING UP").
2.8.31 FINAL DISPOSAL OF THE MACHINE
q
At the end of the working life of the machine, ask Komatsu Distributor for the final disposal.
