Assembly of the Isolator
1. Coat the Isolator Balls (16) with a solution of liquid
soap and place one in each pocket of the Female
Isolator (l7).
2. Secure the Isolator (15) in leather–covered or
copper–covered vise jaws. Install the assembled
Female Isolator including Isolator Balls on the Male
Isolator.
3. Secure the Nose Cap (18) with the Male Nose Cap
Screw (19) using a suitable thread–locking compound
and tighten to a torque of 29 ft–lb (40 Nm).
Assembly of the Barrel
The press fit between the Barrel (33) and the
Nozzle and Cushion Bushing (34) is heavy
interference and a suitably guarded press should
be used.
1. Press the Lower Inner Sleeve (37) onto the large,
chamfered bore end of the Barrel. Secure in place
with the Inner Sleeve Retaining Clip (38). Install the
Retainer O–ring (42).
2. Press the Cushion Bushing into the Nozzle end of the
Barrel (end with the large radius bore) until the
Cushion Bushing has passed the groove where the
Cushion Bushing Retaining Clip (35) fits.
3. Insert the Cushion Bushing Retaining Clip into the
Nozzle end of the Barrel and seat the Clip into the
groove in the Barrel.
4. Press the Cushion Bushing from the Valve end of the
Barrel back down the bore until it seats on the
Cushion Bushing Retaining Clip.
When installing a hexagon nozzle into the barrel,
follow the instructions below.
For European ISO standard shanks:
Ensure that one of the flats of the hexagon is at 90
degrees to the axis of the Handle.
For U.S.A. standard shanks:
Ensure that one of the flats of the hexagon is parallel
to the axis of the Handle. This will ensure that the
cutting edge of a hexagon shank chisel will be parallel
to the axis of the Handle. Since hexagon to cutting
edge orientation can vary in local markets, it is best to
take reference to a chisel which will be used in the
tool.
