The air motor used for this product has been
specifically designed for the application. Use of
any other part other than the ones purchased from
ITW Ransburg may not perform adequately or
may fail prematurely, and will also void all product
warranties.
1. Install the air motor air inlet fitting into the proper
port or the motor. The proper port is the port to the
right when the air motor shaft is pointing upward
and ports are facing forward.
2. Install the exhaust restrictor in the remaining
port.
3. Apply a light coat of dielectric grease (59972-
00) to the mounting shoulder of the air motor.
Locate one of the countersinks in the mounting
shoulder of the air motor. Align the countersink
with the threaded hole in the air motor mounting
plate. Push the air motor straight into the mounting
plate until the generator bottoms out. Tighten the
set screw.
4. Be sure the shaft of the air motor inserts directly
into the coupling. Tighten the coupling set screws
using a 5/64" Allen wrench.

> To extend the life of the air motor, do not
use any Teflon tape past the inlet to the filter
regulator unit. It is recommended to use a
liquid thread sealant such as 7969-10.
