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.

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
