items are Distributor maintenance tasks only.
For normal ambient conditions bulk oil temperatures must not
exceed 90°C/194°F (100°C/212°F for HPO oil) with 2000 hour oil
change periods.
In higher ambient conditions using 4000 hour oil change periods
HPO oil should not exceed 90°C/194°F. In extreme conditions
HPO oil should be used at the 2000 hour oil change periods.
If the oil is working above these temperatures the oil life will be
