in scrap or unseen areas to determine the proper position of the
torque adjustment collar.
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.
Hammerdrill Operation
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.
2. When drilling, use just enough force on the hammer to keep it
from bouncing excessively. 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.
