Unscrew level gauge (1) and wipe it clean. 2. Insert gauge (1), but DO NOT screw in, see detail (A). 3. Remove level gauge and read the oil level.
The oil level should be between the “MIN” and “MAX” mark. If necessary, add oil through filler opening (2) up to the “MAX” mark on gauge (1). NOTICE If the oil level is above the “MAX” mark, drain the oil down until the oil level is at the “MAX” mark. Too much oil in the pump distributor gear will cause aeration of the oil. 4.
