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.
