trigger switch.
To deactivate the lock-on slider, depress the trigger switch
once then release.
The lock-on slider may only be activated in chipping mode.

For continuous operation, move the toggle switch
on position. To stop continuous operation, move the toggle
switch to the off position.
Soft Start Feature
The soft start feature allows you to build up speed slowly,
thus preventing the drill bit from walking off the intended
hole position when starting. The soft start feature also
reduces the immediate torque reaction transmitted to the
gearing and the operator if the hammer is started with the
drill bit in an existing hole.

CAUTION: Do not use a core bit for hammerdrilling
wood. Personal injury and damage to tool may result.
nOTE: The D25831 and D25851 have only chipping modes
with no hammerdrilling capability.
1. Set the mode selector

3. Assemble the centering bit and adapter shank into
core bit.
4. Mark the spot where the hole is to be drilled.
5. Place the centering bit on that mark and depress the
trigger switch 1 .
nOTE: Some core drills require the removal of centering
bit after about 1 cm of penetration. If so, remove and
continue hammerdrilling.
6. When hammerdrilling through a structure thicker than
the depth of the core bit, break away the round cylinder
of concrete or core inside the bit at regular intervals. To
avoid unwanted breaking away of concrete around the
hole, first drill a hole the diameter of the centering bit
completely through the structure. Then drill the cored
hole halfway from each side of the structure.
7. To stop the tool, release the trigger switch.
Always turn the tool off when work is finished and
before unplugging.
