Check Chassis Range! 0000 - Overall system/tractor A - General 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 necessary 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 im- plement.
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. Special features of biodegradable hydraulic oil Biodegradable hydraulic oil is more easily biodegradable and has less of an effect on the ground and groundwater 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. 17 T002823 Version 1 20-01-2009 Use rapeseed-oil and synthetic-based HEES biodegradable hydraulic oil with a viscosity in accordance with ISO VG 32- ISO VG 46. 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. N OTE : Polyglycol-based synthetic oils cannot be used.
