mACHINE PREPARATION
Preparation of the machine and the work area
- Ensure the work area is well-lit.
- Clean the work area, making sure it is dry.
- Clean any oil.
- Examine the upper roller and the lathe screw to ensure
that the size is correct.
- Ensure the tube is firmly held in place and does not
rotate.
- Ensure the tube clamps and hooks can bear the weight
and force of the grooving machine.
- If the tube is not installed, use a vice or screw press on
a tripod to hold the tube in place and make sure the
whole assembly is stable.
Preparation of the tube
The tube ends must be cut at a right angle.
- Do not use a blowtorch to cut the tube.
- The tube must not be insufficiently round.
- It is necessary to grind all the welding seams, sealants
and other interior or exterior seams flush in the tube
over a length of at least 55 mm from the end.
- The grooving machine will trace an orbit around the
tube. The machine must therefore have enough room
to rotate around the tube.
Assembly of the grooving machine
- On a workbench or on the floor, rotate the locknut (see
figure 2, n.2) and the regulating nut (see figure 2, n.1)
anti-clockwise.
- Rotate the guide screw (see figure 2, n.4) anti-clockwise
to “lift” the upper roller from the lathe screw (see figure
2, n.5).
- Place the grooving machine on the tube, leaving the
guide screw accessible.
- Push the grooving machine up against the tube until it
fits completely. The end of the tube should touch the
edge of the lathe screw.
- Rotate the guide screw manually clockwise until the
machine is secured. The grooving machine is held in
position on the tube.

Adjustment of the knurling depth
- Once you have tightened the guide screw by hand and
the machine is secured on the tube, position the depth
gauge (see figure 3, n.3) between the machine and the
regulating nut.
- Rotate the regulating nut clockwise towards the machine
until the gauge is secured in place.
- Rotate the regulating locknut clockwise until it touches
the regulating nut.
- Remove the depth gauge.
