ENGLISH

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 drillingrate.

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

drillingspeed.

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 thehole.

5. For masonry, use carbide-tipped bits or masonry

bits. A smooth even flow of dust indicates the proper

drillingrate.
