Dewalt DCD792B Instruction Manual - Page 14

English WARNING: Drill may stall if overloaded causing a sudden twist. Always expect the stall. Grip the drill firmly to control the twisting action and avoid injury. 5. IF DRILL STALLS, it is usually because it is being overloaded or improperly used. RELEASE TRIGGER IMMEDIATELY, remove drill bit from work, and determine cause of stalling. DO NOT depress TRIGGER ON AND OFF IN AN ATTEMPT TO START A STALLED DRILL - THIS CAN DAMAGE THE DRILL. 6. To minimize stalling or breaking through the material, reduce pressure on drill and ease the bit through the last fractional part of the hole. 7. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent jamming. Hammerdrilling (Fig. F) DCD797 Only 1. Select the desired speed/torque range using the gear shifter to match the speed and torque to the planned operation. Turn the collar 3 to the hammerdrill 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 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.
