the main factor as it effects the operating viscosity. If necessary a list of recommended food grade oils is available on
request.
If the unit runs below the catalogue rating and operates at a
temperature below 60 oC then a light grade oil should be used.
Operating at catalogue rating with temperatures up to 100 oC
requires medium grade.

Using too heavy a grade than required will result in reduced

efficiency, too light a grade will result in premature wear. If in
doubt ask Renold Gears Technical Department.
Heavy grade oils are shown for reference only.
