They are calculated on the basis of an average oil temperature of 8 : for mineral oils, biologically degradable oils and physiologically safe (synthetic esters) oils 2 years or 1 0 operating hours (does not apply to natural esters rape seed oils, etc. ). for poly--olefins and polyglycols, 4 years or 2 0 operating hours. The actual service lives may differ. The general rule is that an increase in temperature of 1 will halve the service life and temperature decrease of 1 will approximately double the service life. 1.2 Description of maintenance and repair work 1.2.1 Examine water content of oil / conducting oil analyses More information about examining the oil for water content or conducting oil analyses is obtainable from your lubricant manufacturer or our customer service. For reference purposes, fresh sample of the operating lubricating oil used must be sent with the used oil sample to the analysing institute for analysis. The oil sample must be taken downstream of the filter of the oilsupply system while the gear unit is running. suitable connection point is normally located upstream of the gear unit input (.. oildrain cock in the pressure line). special sample container should be filled with the specified quantity of oil. If there is no such sample container available, at least one litre of oil must be put in clean , transportworthy, sealable vessel. 1.2.2 Change oil As an alternative to the oilchange intervals indicated in Table 4 (see item 1. it is possible to have the oil sample tested at regula
