Select the smallest speed.
Switch the rotation of the spindle on. Note the correct direction of rotation (12) or (14).
Move the sleeve downward with the sleeve lever until the machine tap cams in the work-
piece.
The machine tap turns into the workpiece. As soon as the preset depth is attained, the spindle

piece. When the sleeve is completely entered up to the switch point (22) the rotation of the
spindle is stopped. Then it is possible to proceed another threading operation.
ATTENTION!
Before proceeding another threading cycle, the sleeve must be completely entered in order to
trigger the switch point (22).
The selector switch automatic spindle sleeve feed (26) must be in the "OFF" position.
