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.
