LUBRICATION
NOTE
Pneumatically actuated devices require clean, pressure regulated, and lubricated air for maximum performance
and long life. The most effective and economical way to lubricate Nexen Clutch/Brakes is with an Air Line
Lubricator, which injects oil into the pressurized air, forcing an oil mist into the air chamber.
Locate the lubricator above and within ten feet of the Clutch/Brake, and use a low viscosity oil such as SAE-10.
Synthetic lubricants are not recommended.

2. Turn the Lubricator Adjustment Knob clockwise three
complete turns.
3. Open the air line.
4. Close the air line to the unit when a drop of oil forms
in the Lubricator Sight Gage.
5. Connect the air line to the unit.
6. Turn the Lubricator Adjustment Knob counterclockwise
until closed.
7. Turn the Lubricator Adjustment Knob clockwise one-
third turn.
