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 FMBES 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 FMBES, and use a low viscosity oil such as SAE-10.
Synthetic lubricants are not recommended.

These settings are for Nexen supplied lubricators. If you are not using a Nexen lubricator, calibration must replicate
the following procedure.

complete turns.
3.
