part of the tool into aliquid.
C
Lubrication
Your power tool requires no additionallubrication.
MAINTENANCE
Your power tool has been designed to operate over a long
period of time with a minimum of maintenance. Continuous
satisfactory operation depends upon proper tool care and
regularcleaning.
IMMEDIATELY, remove drill bit from work, and determine
cause of stalling. DO NOT CLICK TRIGGER ON AND OFF
IN AN ATTEMPT TO START A STALLED DRILL  THIS
CAN DAMAGE 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 (Fig.A,E)
DCD796only
1. Turn the collar
3
to the hammerdrillsymbol.
2. Select the high speed setting by sliding the gear shifter
4
back (away from thechuck).
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
3
to the desiredposition.
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.

WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect battery pack
before making any adjustments or removing/
installing attachments or accessories. An accidental
start-up can causeinjury.
The charger and battery pack are notserviceable.
