2. When drilling, use just enough force on the hammer
to keep it from bouncing excessively or “rising” off the
bit. Too much force will cause slower drilling speeds,
overheating, and a lower drillingrate.
3. 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
drillingspeed.
4. 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 thehole.
5. For masonry, use carbide-tipped bits or masonry
bits. A smooth even flow of dust indicates the proper
drillingrate.
