The machine is equipped with reversible direction of rotation and
can also be used for cutting threads.
In order to cut threads, proceed as follows:
Drill the hole for the thread.
‹
Switch off the machine and select the lowest gear stage and
‹
speed.
Set the direction of rotation to clockwise (right = R) at
‹
switch (23).
Tighten the drill tap in the machine using the appropriate drill
‹
tap adapter.
Switch on the machine and place the drill tap onto the drilled
‹
hole.
Use the hand lever (11) without exerting pressure to guide
‹
the machine until the desired thread length has been cut.
Switch off the machine and set the direction of rotation to
‹
anti-clockwise (left = L) at switch (23).
Switch on the machine again and allow the drill tap to com-
‹
pletely emerge out of the workpiece. Then use the hand lever
(11) to guide the machine slide upwards in order to avoid
damaging the top of the thread.
Thanks to its wide range of operating speeds, the machine can
also be used for reaming or counter-sinking.
CAUTION
► When reaming and counter-sinking, observe the limits stated
in the technical data for the tools to be used.
