Maintenance - DeWalt DCD985-XE Instruction Manual

2. Rotate the mode control collar (F) so the screw symbol is aligned with the arrow.
3. Make a few practice runs in scrap or unseen areas of the workpiece to determine
the proper position of the torque 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. 5)
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.
