.
Selecting the Operating Mode (Fig. A)
Hammerdrilling:
D25501, D25601, D25602, D25603
for concrete, brick, stone and masonry drillingoperations.
Hammering only:
D25501, D25601, D25602, D25603, D25820, D25831
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
6
until
it points to the symbol of the requiredmode.
It may be neccessary to twist the tool holder
12
slightly to allow the
mode selector switch
6
to pass the position.
2. Check that the mode selector switch
6
is locked inplace.
Indexing the Chisel Position (Fig. E)
D25501, D25601, D25602, D25603, D25820,
D25831
The chisel can be indexed and locked into 18 differentpositions.
1. Rotate the mode selector switch
6
until it points towards the
position.
2. Rotate the chisel in the desiredposition.
3. Set the mode selector switch
6
to the “hammering only”position.
4. Twist the chisel until it locks inposition.
Setting the Electronic Speed and Impact Control Dial
(Fig. A, C)
D25601, D25602, D25603, D25831
Turn the dial
7
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 Two Stage Mechanical Clutch (Fig. C)
D25602, D25603
NOTICE: Always turn the tool off before changing torque control
settings or damage to the tool mayresult.
Move the torque control lever
21
to setting 40Nm or 80Nm as needed
forapplication.
• Clutch Setting 40Nm
19
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
20
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: If it is not possible to select position 80Nm, run the unit under load
and tryagain.
Each time the tool is plugged in, it will automatically default to clutch
setting 1 into clutch setting 40Nm
19
, the most sensitivesetting.
Depth Rod
(Additional Accessory)
1. Push in and hold the depth rod release button on the sidehandle.
2. Move the depth rod so the distance between the end of the rod and
the end of the bit equals the desired drillingdepth.
3. Release the button to lock rod intoposition. When drilling with the
depth rod, stop when end of rod reaches surface ofmaterial.
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. Be sure the trigger switch is in the OFFposition. An
accidental start-up can causeinjury.

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 (approximately 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.
Proper Hand Position (Fig. F)

WARNING: To reduce the risk of serious personal injury, ALWAYS use
proper hand position asshown.

WARNING: To reduce the risk of serious personal injury, ALWAYS hold
