Operation - DeWalt SDS MAX D25711 Instruction Manual

Selecting the Operating Mode
(fi g. 1)
Hammerdrilling:
D25711, D25712, D25713, D25762, D25763
for concrete, brick, stone and masonry
drilling operations.
Hammering only:
for chiselling and demolition applications.
In this mode the tool can also be used as
a lever to free a jammed drill bit.
1. To select the operating mode, rotate the mode
selector switch (f) until it points to the symbol of
the required mode.
It may be neccessary to twist the tool holder (m)
slightly to allow the mode selector switch (f) to
pass the position.
2. Check that the mode selector switch (f) is
locked in place.
Indexing the Chisel Position
(fi g. 5)
The chisel can be indexed and locked into 24
different positions.
1. Rotate the mode selector switch (f) until it points
towards the position.
2. Rotate the chisel in the desired position.
3. Set the mode selector switch (f) to the
"hammering only" position.
4. Twist the chisel until it locks in position.
Setting the Electronic Speed and
Impact Control Dial (fi g. 1, 3)
Turn the dial (g) to the desired level. Turn the dial
upwards for higher speed and downwards for
lower speed. The required setting is a matter of
experience. E.g.:
– when chiselling or drilling in soft, brittle materials
or when minimum break-out is required, set the
dial to a low setting;
– when breaking or drilling in harder materials, set
the dial to a high setting.
Setting the Torque Control Switch
(fi g. 3)
D25712, D25713, D25762, D25763
NOTICE: Always turn the tool off before
changing torque control settings or
damage to the tool may result.
Move the torque control lever (t) to setting 40 Nm or
80 Nm as needed for application.
Clutch Setting 40 Nm (u) is designed
for most drilling applications and is
designed to easily clutch out when the
drill bit encounters re-bar or other foreign
substances.
Clutch Setting 80 Nm (v) is designed for
higher torque applications such as core-
bits and deep hole drilling and is designed
to clutch out at a higher torque threshold.
NOTE: Allow the motor housing to rotate a little
while changing torque.
Each time the tool is plugged in, it will
automatically default to clutch setting 1 into
clutch setting 40 Nm (u), the most sensitive
setting.

OPERATION

Instructions for Use
WARNING: Always observe the safety
instructions and applicable regulations.
WARNING: To reduce the risk
of serious personal injury, turn
tool off and disconnect tool from
power source before making any
adjustments or removing/installing
attachments or accessories.
WARNING: Tool bits may be hot and
gloves should be worn when changing
or removing them to avoid personal
injury.
WARNING:
Be aware of the location of pipework
and wiring.
Apply only a gentle pressure to
the tool (approx. 20 kg). Excessive
force does not speed up drilling but
decreases tool performance and may
shorten tool life.
Always hold the tool firmly with both
hands and ensure a secure stance.
Always operate the tool with the side
handle properly assembled.
NOTE: Operating temperature is (-7 to +40˚ C (19˚
to 104˚ F). Using the tool outside of this temperature
range will decrease the life of the tool.
