DRILLING SCREWDRIVING HAMMERDRILLING
Hammerdrilling (Fig. 10)
1. Select the desired speed/torque range using the gear shifter to
match the speed and torque to the planned operation. Turn the
collar (C)to the hammerdrill symbol.
IMPORTANT: Use carbide-tipped or masonry bits rated for
percussion drilling only.
2. Drillwith just enough force on the hammer to keep itfrom 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 drillling 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 tool still running to help
clear debris from the hole.
NOTE: A smooth, even flow of dust from the hole indicates proper
drilling rate.
