adjustment collar. Reset the torque adjustment collar (E) to the
appropriate number setting for the torque desired.
4. Always start with lower torque settings, then advance to higher
torque settings to avoid damage to the workpiece or fastener.
NOTE: The torque adjustment collar may be set to any number at any
time. However, the torque adjustment collar is only engaged during
screwdriving mode and not in drill and hammerdrill modes.
Hammerdrilling (Fig. 6)
1. Select the desired speed/torque range using the gear shifter to
match the speed and torque to the planned operation. Set the
mode control collar to the hammer symbol.
IMPORTANT: Use carbide-tipped or masonry bits rated for
percussion drilling only.
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.
