Biodegradable Oil
Biodegradable oil
Biodegradable oil is a new type of hydraulic oil that is decomposed into carbon dioxide and
water by microorganisms in the soil and water. It is highly safe for living organisms and offers
advantages in terms of environmental protection.
�
Recommended biodegradable oil: Mobile EAL Envirosyn 46H (an ester synthetic oil).
When replacing the hydraulic oil with biodegradable oil, use the above or an equivalent oil.
Note that other oils, even other brands of ester synthetic oils, may damage O-rings, packings
and seals. Takeuchi products shipped with the optional biodegradable oil are shipped with
the above brand of oil.
�
When switching from a mineral oil to a biodegradable oil, the parking brake torque decreases
by about 30%.
Replacing the hydraulic oil with biodegradable oil
Mixing mineral oil with biodegradable oil will result in a decrease of the hydraulic oil’s performance
as well as a decrease in biodegradability and safety. The hydraulic oil system must be flushed
as described below before supplying the biodegradable oil. This operation is dangerous and
requires experience. Have it performed by a Takeuchi sales or service outlet.
Flushing
To be performed by a Takeuchi sales or service outlet
1. Drain the hydraulic oil (mineral oil) from the hydraulic tank and clean the inside of the tank
and suction strainer. (Refer to the section on replacing the hydraulic oil and cleaning the
suction strainer.)
2. Remove the cylinder hoses and drain the hydraulic oil (mineral oil) from inside the
cylinders.
3. Supply new biodegradable oil to the hydraulic tank.
4. Bleed the air from the hydraulic pump, control valve, slew motor and cylinders.
5. Operate the hydraulic devices for 30 minutes.
6. Drain the biodegradable oil from the tank and cylinders.
7. Replace the hydraulic oil return filter with a new filter.
8. Repeat steps 3 and 4.
9. Operate the hydraulic devices for 30 minutes.
10. Drain the biodegradable oil from the tank and cylinders.
11. Repeat steps 3 and 4.
12. Operate the hydraulic devices for 1 hour.
13. Drain the biodegradable oil from the tank and cylinders.
14. Replace the return filter with a new filter.
15. Repeat steps 3 and 4.
16. Operate the hydraulic devices, then check for oil leakage.
There is no need to flush the hydraulic oil system when switching from biodegradable to
mineral hydraulic oil.
