The lock-on slider may only be activated in chipping mode.
The machine will stop running when trying to engage the
lock-on slider in hammerdrilling mode. The motor will stop
if the lock-on slider is activated when changing from chisel
mode into hammerdrillingmode.
D25820, D25831, D25851
For continuous operation, move the toggle switch to the
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.

D25501, D25601, D25602
NOTE: The D25820, D25831, D25851 has only chipping
modes with no hammerdrillingcapability.
1. Set the mode selector
6
to hammerdrillingmode.
2. For D25602 only, move the torque control lever
8
to
Setting 1
14
.
3. Set the speed and impact control dial

7. Place the drill bit on that mark and depress the trigger
switch
1
.
8. Apply only enough pressure to engage active vibration
control (refer to Active VibrationControl).
9. To stop the tool, release the trigger switch.
Always turn the tool off when work is finished and
beforeunplugging.
Hammerdrilling with a Core Bit (Fig. A, E)
D25501, D25601, D25602

CAUTION: Do not use a core bit for hammerdrilling
wood. Personal injury and damage to tool mayresult.
Note: The D25820, D25831, D25851 has only chipping
modes with no hammerdrillingcapability.
1. Set the mode selector
6
to hammerdrillingmode.
2. For D25602 only, move the torque control lever
8
to
Setting 2
11
.
3. Turn the speed and impact control dial
7
to the
maximum speed (level7).
4. Adjust the side handle (front or rear position)
3
.
5. Assemble the centering bit and adapter shank into
corebit.
6. Mark the spot where the hole is to bedrilled.
7. 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.
8. 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.
9. To stop the tool, release the trigger switch.
Always turn the tool off when work is finished and
beforeunplugging.
