Biodegradable hydraulic oil
Oil quality
Use rapeseed-oil and synthetic-based HEES biodegradable hydraulic oil with a viscosity in accordance with
ISO VG 32-ISO VG 46.
N
OTE
:
Polyglycol-based synthetic oils cannot be used.
Instructions for use
Biodegradable hydraulic oil is suitable for winter temperatures down to approx. -15 °C.
Vegetable-based hydraulic oil may thicken in outside temperatures below approx. -15 °C or if the tractor is
not used for long periods of time. After a cold start, allow a short warm-up time at medium engine speed to
ensure safe operation of the hydraulic steering and linkage. In extremely low temperatures, it may be neces-
sary to warm up the entire tractor.
Avoid mixing with mineral oils, e.g. with any oil remaining in the system or by connecting and operating an
external implement. This may affect the positive environmental properties of the fluid, and will make it more
difficult to dispose of (it will then have to be considered as special waste).
Current legislation and the instructions of the oil manufacturer must be observed when disposing of oil.
A mixture containing more than 20% may result in alterations in viscosity and may lead to problems with the
hydraulic valves.
Maintenance intervals
The oil and oil filter need to be changed every 1000 running hours or every year, whichever occurs first.
When switching to biodegradable hydraulic oil, change the hydraulic oil filter after approx. 50–100 running
hours. Since biodegradable hydraulic oil acts as a solvent, any oil residue may block the filter.
Special features of biodegradable hydraulic oil
Biodegradable hydraulic oil is more easily biodegradable and has less of an effect on the ground and ground-
water in the event of accidental spills.
I
MPORTANT
:
In spite of the high environmental compatibility of biodegradable hydraulic oil, accidental spills
must always be reported.
