Refer to Figure 4.
1. Ensure the Set Screw (Item 17) that locks the Adjustment
Nut (Item 16) is released to allow the Adjustment Nut to
be rotated on the Hub.
2. Using a 0.020 In. [0.508 mm] and a 0.060 In. [1.514
mm] feeler gauge, check the gap between the Friction
Disc and the Friction Facing.
a. If the gap is less than 0.020 In. [0.508 mm], rotate
the Adjustment Nut counterclockwise until one set
screw hole is over the flat on the Hub and the 0.020
In. [0.508 mm] feeler gauge can be inserted.
b. If the gap is greater than 0.060 In. [1.514 mm],
rotate the Adjustment Nut clockwise until one set
screw hole is over the flat on the Hub and the 0.060
In. [1.514 mm] feeler gauge can not be inserted.
3. Tighten the Set Screw to the recommended torque (See
Table 5).
NOTE: Do not adjust the gap to less than 0.020 In.
[0.508 mm]. The Air Champ II will not disengage
if the gap is closed.

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.

1. Close and disconnect the air line from the unit.
2. Turn the Lubricator Adjustment Knob counterclockwise
three complete turns.
3. Open the air line.

CAUTION
These settings are for Nexen supplied
lubricators. If you are not using a Nexen
lubricator, calibration must follow the
manufacturer's suggested procedure.
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 clockwise until
closed.
7. Turn the Lubricator Adjustment Knob counterclockwise
one-third turn.
8. Open the air line to the unit.
