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 term 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 “Replacing the hydraulic oil and
cleaning the suction strainer” on page 5-
46.
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.
BIODEGRADABLE OIL
4. Bleed the air from the pump and cylinders
and pressurize the hydraulic tank.
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.
