7.7 Tapping
Tapping can be done as follows:
• Turn the switch for drilling and tapping in the ‘TAPP’ position.
• Set the depth with the depth adjustment on the right-hand side of the
machine (see also 5.2).
• Turn the switch for high or low speed to ‘OFF’.
• Set the speed with the rotary speed knob.
• Move the spindle downwards with the feed handles.
When the set depth is reached, the turning direction of the spindle
automatically reverses and the spindle can be taken out of the tapping
hole.
Always use a low speed for tapping!
