b) Drilling / Stirring / Screwing
Drilling with diamond drill bits
Switch the hammer action off when drilling
with a diamond drill bit.
Set the operation mode switch [1-4] to
drilling.
Screwing
The screw adapter [2-2] (accessory) can
hold screw bits.
Commercially available bits with a hexago-
nal dimension of 6.3 mm or 1/4" (DIN 3126,
Form C) can be used. The screw-bits are
held in the adapter with a spring ring.
Therefore, use only bits with a notch.
Set the operation mode switch [1-4] to
drilling.
