2. 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 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.
NOTE: A smooth, even flow of dust from the hole indicates proper
drilling rate.
