Note:
The heads of the screws are located down
inside the cylinder cavity.

Rotor
To remove the rotor (Ref. 5), screw a 5 mm cap screw
into a threaded hole in the face of the rotor. Use a long
bar or screwdriver between the cap screw and socket to
prevent the rotor (Ref. 5) from turning while you
unscrew the M6 cap screw (see Fig. 11). Set the cap
screw, lockwasher (Ref. 10) and tightening disk (Ref. 8)
aside.
Install a bar puller on the rotor (see Fig. 12). Advance
the puller until the rotor is loose on the shaft and can be
removed from the shaft.

CLEANING AND INSPECTION
5.1
General
Use compressed air to blow off all parts. When neces-
sary, soak the parts in a degreasing solution, agitate
and scrub to remove any grimy residue, and then rinse
and blow dry.
Clean off any surface scale.
Inspect the sealing surfaces. Use a honing stone to
polish out nicks and scratches.
5.2
Filter Housing
Use compressed air to blow off the filter element (Ref.
27). Do not damage the pleats. If the element materi-
al looks clogged, replace it. Inspect the filter spring for
corrosion or damage. Check the silencer valve (Ref.
32) for operation and build-up of residue. Check the
vacuum relief valve for any build up of dust or particu-
late.
5.3
Endplates
Clean the intake and exhaust cavities in the endplate
(Ref. 18).
5.4
Rotor
Clean the vane slots. Check the vane movement in the
slots. The vanes must drop freely in the slots.

shaft. Alternate methods could damage the
motor bearings.
