Clean the spindle and the broach cutter of any swarf with the brush provided.
Ensure that swarf is removed before carrying out another drilling process.
12.2) Drill fi tted with special spiral bit
Follow the sequence described in §
12.1
, taking care to position the drill on the rail by keeping the
spindle fully
withdrawn
. Bear in mind that the coolant circuit, instead of being automatically opened and closed by the guide
bit, is kept open at all times by the APED adapter or DPE spacer fi tted on the spigot of the spiral bit; it must therefore
be activated, by opening the tap, before starting to drill, then switched off after drilling by closing the tap.
Normally, using twist drill bits up to Ø 13 mm (Ref. to
§ 3.11
) does not require a force that illuminates the
green LED on the indicator.
In such a case, it is however acceptable for the WHITE LED to remain illuminated.
