TAPMATE
™
XL-424 Operating Manual
PERFORMING THE TAP:
1. Slowly thread the Brake Tube forward on the Thrust
Tube by rotating the Brake Tube Handles in a
clock-wise direction. This slides the Shaft, Shaft Nose
(or PVC Pilot) and Cutter, through the Valve and neck
of the tapping sleeve.
2. Continue until you feel resistance, or run out of travel
on the Thrust Tube (which may occur with some 20
and 24” taps). Stop rotating the Brake Tube Handles.
Notice that the holes in the Brake Tube Collar may not
be aligned over the scale on the Thrust Tube (see
drawing at left).
Rotate the Brake Tube back (counter-clockwise) until
the next hole in the front collar of the Brake Tube lines
up with the scale in the Thrust Tube.
Thread the Brake Tube Locking Bolt into the
collar of the Brake Tube, and securely tighten. It needs
to bear down directly onto the scale and NOT the
threads of the Thrust Tube (see drawing at left).
Note
:
The Locking Bolt can ratchet if necessary to
avoid the Lead Nut Handles and / or their rotational
path.
3. If you have run out of travel on the Brake Tube /
Thrust Tube assembly:
Rotate the Lead Nut Handles (clock-wise) to feed the
Cutter. Stop when resistance is felt.
NOTE: Holes and
Scale misaligned.
NOTE: Alignment of
hole over Scale.
