A Mobile Oil, DTE Medium, or equivalent, is recommended. See the following table for
acceptable oil specifications.
Note:
• Oils from different suppliers should not be mixed.
• Engine oils are not recommended.
• The oil should be non-foaming, well refined, high grade, straight cut, filtered mineral
oil. The oil must be free of water, sediment, resin, soaps, acid, and fillers of any kind.

1. Disassemble the oiler by unfastening the thumb screw on the side. Separate the upper
housing and bulb from the lower housing. Remove the level adjuster from the interior
of the lower housing.
2. Spin the wing nut of the oil level adjuster to the desired level. The adjuster should be
set such that the oil level within the bearing housing will be centered with the lowest
ball of the bearing. The position of the sight glass is aligned with this level. See Figure
20: Recommended sight glass oil level on page 39 for more information.
