3. Drill with 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 lower drilling rate.
4. Drill straight, keeping the bit at a right angle to the work. Do
not exert side pressure on the bit when drillling 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 tool still running to
help clear debris from the hole.
nOTE: A smooth, even flow of dust from the hole indicates
proper drilling rate.
