Put the spring aside. Lubricate the
top edge of the chisel shank chamfer
with oil or light grease and then insert
the chisel from the ellipse opening of
the Retaining Sleeve (16). (See Fig.
2.)
4. During usage, the Retaining Sleeve
(16) ledge may be slightly elongated,
preventing insertion of the chisel into
the Retaining Sleeve. It may require
some force to get the Chisel’s lobes
past this point and to slide into the
chisel mounting channel.

tach the Chisel and Retaining Sleeve

7. There is an O-Ring (9) inside the
channel about half way down. The
chisel may stop here. Apply a little
more force to push the chisel past the
O-ring, and into the channel.
