NOTE
Nexen pneumatically actuated devices require clean, pressure regulated air for maximum performance
and life. All seals in Nexen Pneumatically operated devices are lubricated for life and do not require
additional lubrication.
However, some customers prefer to use an air line lubricator, which injects oil into the pressurized air,
forcing an oil mist into the air chamber. This is acceptable, but care must be taken to ensure once an air
mist lubrication system is used, it is continually used over the life of the product as the oil mist may wash
free the factory installed lubrication.
Locate the lubricator above and within ten feet of the product, and use low viscosity oil such as SAE-10.
Synthetic lubricants are not recommended.
Nexen product's bearings are shielded and pre-lubricated, and require no further lubrication.
5. Connect the air line to the unit.
6. Turn the Lubricator Adjustment Knob clockwise until
closed.
7. Turn the Lubricator Adjustment Knob counterclockwise
one-third turn.
8. Open the air line to the unit.
LUBRICATION
CAUTION
These settings are for Nexen supplied

manufacturer's suggested procedure.
