remove drill bit from work, and determine cause of stalling.

THE DRILL.
7. To minimise stalling or breaking through the material,
reduce pressure on drill and ease the bit through the last
fractional part of the hole.
8. Keep the motor running when pulling the bit back out of a
drilled hole. This will help prevent jamming.
9. With variable speed drills there is no need to centre punch
the point to be drilled. Use a slow speed to start the hole
and accelerate by squeezing the trigger harder when the
hole is deep enough to drill without the bit skipping out.
Hammerdrill Operation (DCD796 only)
(Fig. A, E)
1. Turn the collar 3 to the hammerdrill symbol.
2. Select the high speed 2 setting by sliding the gear
shifter back (away from the chuck).
4
IMPORTanT: Use carbide-tipped or masonry bits only.
3. 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 lower
drilling rate.
4. 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.
5. When drilling deep holes, if the hammer speed starts to
drop off, pull the bit partially out of the hole with tool stil
running to help clear debris from the hole.
nOTE: A smooth, even flow of dust from the hole indicates
proper drilling rate.
Screwdriver Operation (Fig. A, F)
1. Turn the torque adjustment collar
2. Select the desired speed/torque range using the
gear shifter 4 to match the speed and torque of the
planned operation.
nOTE: Use the lowest torque setting required to seat the
fastener at the desired depth. The lower the number, the
lower the torque output.
3. Insert the desired fastener accessory into the chuck as you
would any drill bit.
4. Make some practice runs in scrap or on unseen areas to
determine the proper position of the clutch collar.
5. Always start with lower torque settings, then advance to
higher torque settings to avoid damage to the workpiece
or fastener.
