Please note: Swanneck machining tolerances result in small variances in length;
consequently the measurements given below are intended for reference only (for
example, to help identify loose cut neck liners).
If installing a neck liner into a new swanneck or swanneck
without old neck liner for measuring length:
1. Fit the consumables (diffusor/insulator, tip-holder, contact tip, nozzle) onto the swan-
neck.
2. Insert the neck liner into the swanneck as far as it will go.
3. Measure the length of liner sticking out from the back of the swanneck and subtract
1mm. (When cut and installed correctly, the neckliner should stick out approximately
1mm. without tension.)
4. Remove the liner and measure the length from step 3 back from the inserted end and
mark carefully. With a pair of sharp cutters, cut off the excess liner.
5. Check to ensure that there are no burrs or obstructions to the inner
diameter of the liner.
6. Insert the liner into the swanneck, fi t the swanneck on the gun body in the desired
position and tighten the swanneck locking ring.

If replacing an existing neck liner:
1. Unscrew the swanneck, remove the old neck liner and measure its length.
2. Carefully cut the new neck liner to the same length as the old liner with a pair of
sharp cutters.
3. Check to ensure that there are no burrs or obstructions to the inner
diameter of the liner.
4. Insert the cut liner into the
swanneck. When cut and
installed correctly, the neck
liner should stick out
approximately
1mm.
without being held in.
6. Replace the swanneck
on the gun body in the
preferred position and
tighten the swanneck
locking
ring.
