DeWalt DCD937-XE, Instruction Manual

Page: 14 / 16

Hammerdrill Operation (Fig. 5)
1. Select the desired speed/torque range using the gear shifter to match the speed
and torque to the planned operation. Set the torque adjustment collar (E) to the
hammer symbol.
2. Select the high speed 3 setting by sliding the gear shifter (F) back (away form the
chuck).
3. When drilling, use just enough force on the hammer to keep it from bouncing
excessively. Prolonged and too much force on the hammer will cause slower
drilling speeds and potential overheating.
4. 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.
5. 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.
6. For masonry, use carbide-tipped bits or masonry bits. A smooth, even flow of
dust indicates the proper drilling rate.
