NOTE:
lubricant.
2. Verify the o-rings on the first spool assembly (3)
are properly seated and carefully insert it into one
of the ports of the air motor assembly (2). The
o-ring at the end of the spool assembly (3) fits
into a groove at the bottom of the port. It may be

were not nicked or broken when the spool
assemblies (3) were inserted.
a. Attach an air hose to the port on the body (1).
