2. Select the high speed 3 setting by sliding the
gear shifter (F) back (away form the chuck).
3. When drilling, use just enough force on the
hammer to keep it from bouncing excessively.
Prolonged and too much force on the hammer
will cause slower drilling speeds and potential
overheating.
4. Drill straight, keeping the bit at a right angle to
the work. Do not exert side pressure on the bit
when drilling as this will cause clogging of the
bit flutes and a slower drilling speed.
5. When drilling deep holes, if the hammer speed
starts to drop off, pull the bit partially out of
the hole with the tool still running to help clear
debris from the hole.
6. For masonry, use carbide-tipped bits or
masonry bits. A smooth, even flow of dust
indicates the proper drilling rate.
