Important - DeWalt DCD771 Manual De Instrucciones

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.
Screwdriving (Fig. 8)
1. Select the desired speed/torque
range using the gear shifter to
match the speed and torque to
the planned operation.
2. Turn the torque adjustment
collar (C) to the desired position.
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 of
the workpiece to determine the proper position of the torque
adjustment collar.
5. Always start with lower torque settings, then advance to higher
torque settings to avoid damage to the workpiece or fastener.

Hammerdrill Operation (Fig. 9)
DCD776
1. Turn the collar (C) to the
hammerdrill symbol.
2. Select the high speed setting by
sliding the selector 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.
MAINTENANCE
WARNING: To reduce the risk of serious personal injury,
turn tool off and remove the battery pack before making any
adjustments or removing/installing attachments or accessories.
An accidental start-up can cause injury.
Your D WALT power tool has been designed to operate over a
E
long period of time with a minimum of maintenance. Continuous
satisfactory operation depends upon proper tool care and regular
cleaning.
