OPERATION

Operation of the grooving machine

The thickness of the tube wall must not exceed the

aforementioned maximums.

1. Use the wrench to rotate the guide screw clockwise

one and a half turns. Ensure that the tube remains

flush against the edge of the lathe screw.

2. Remove the wrench from the guide screw and place

it in the transmission shaft. Rotate the wrench so that

the grooving machine traces an orbit once around the

tube.

3. Remove the wrench from the transmission shaft and

place it in the guide screw. Rotate the guide screw

clockwise a half turn. If you tighten the guide screw

too much or leave it too loose, the grooving machine

may fall out or slip inside the tube.

4. Repeat steps 2 and 3 until the regulating nut touches

the machine.

5. Remove the wrench from the guide screw and place

it in the transmission shaft. Rotate the wrench so that

the grooving machine makes two turns around the

tube and completes the groove evenly.

6. Remove the wrench from the transmission shaft and

place it in the guide screw.

7. Rotate anti-clockwise to release the tube from the

grooving machine.

8. Remove the grooving machine from the tube, holding

the handle firmly to avoid dropping it.

Replacement of the roller set

- On a workbench or on the floor, rotate the guide screw

anti-clockwise to “lift” the upper roller (see figure 4, n.7)

completely from the lathe screw (see figure 4, n.8).

- Loosen the fixing stud from the roller slide (see figure 4,

n.9) and remove the roller shaft (see figure 4, n.6).

- Add lubricating grease to the pin bearing inside the

upper roller.

- Remove the upper roller and the adjusting washers (see

figure 4, n.10) from the roller slide.

- Loosen the screw from the lathe screw (see figure 4,

n.11).

- Extract the lathe screw and the washer from the main

drive shaft.

- Place the new lathe screw on the main drive shaft.

- If the new lathe screw is for 1 or 1

1/4

- 1

1/2

inch tubes,

secure it by tightening the screw (see figure 4, n.16).

- If the new lathe screw is for 4 to 6 inch Sch 40 tubes,

or 8 to 12 inch Sch 10 tubes (see figure 4, n.14), place

the lathe screw support (see figure 4, n.12) and secure

it by using the pin as a guide (see figure 4, n.13) and

tightening the screws (see figure 4, n.15).

- Tighten the screw with the washer to the lathe screw.

- Add lubricating grease to the pin bearing inside the

upper roller.

- Place the adjusting washers on both sides of the new

upper roller and insert in the roller slide. Ensure that for

upper rollers up to 6” the measuring mark is at the front.

- Align the upper roller and the washers with the hole and

insert the roller shaft.

- Tighten the roller slide fixing stud and secure the roller

shaft.
