When the drill has passed through the
pipe wall, switch the ratchet reversing
lever and start turning by the ratchet
counterclockwise. Do not use too much
force, but try to keep the milling in motion
without stopping.
Remember to lubricate the milling pin.
When the entire ellipse is milled, lift the
T-65 by the handle and only after the
machine is lifted fully, stop the drill.
Detach the power cord from the T-65 machine.
Remove the T-65 machine from the pilot hole cutter, and remove pilot hole cutter from the
base plate. Clean metal chips from the tube before collaring.
8.2.1 INTERRUPTION OF PILOT HOLE MILLING
If the pilot hole milling process is interrupted, for example, because of pin breakage, do
not restart milling from the starting point, but as close as possible to the point where the
process was interrupted.
Example of interruption and continuing:
1
2
3
4
1. Start milling of the pilot hole.
2. The milling pin breaks.
* Change new milling pin.
3. Continue milling from as close to the
point of breakage as possible.
4. Finished pilot hole.
If the milling is continued from already milled (empty) area, the machine will rush, and
that may cause danger and pilot hole quality deteriorates.
Risk of pin breakage if the milling is started on already milled (empty) area!
