BEFORE STARTING TO USE YOUR
HAMMER DRILL
Examine the place where the tool is to be used for
■
hidden electrical cables, gas, and water pipes using a
pipe finding device.
Before you plug in your tool, make sure that the voltage
■
used corresponds to that indicated on the rating plate.
FITTING AND CHANGING BITS (FIG. 2)
The device is equipped with an SDS-plus attachment
system.
Clean the bit and grease it with a thin layer of
■
machine grease before inserting it into the chuck.
Pull back the fastening sleeve (A. Fig. 2) and hold it.
■
Push and rotate the dust-free tool into the bit holder
■
as far as it will go. The bit will lock automatically.
Check that it has locked by pulling on it.
■
REMOVING THE BIT FROM THE SDS-PLUS
SYSTEM (FIG. 3)
Pull back the fastening sleeve (A) and remove the bit.
SWITCHING ON/OFF
Speed control
■
You can modify the speed at any time by pressing on
the variable switch (2). The more you press on the
variable switch (2), the greater the speed.
Lock-on button
■
If you want to keep your hammer drill operating at a
constant speed, press the lock-on button (3) while
pressing the variable switch. To unlock this function,
briefly press the variable switch (2) then release it.
AUXILIARY HANDLE (FIG. 4)
For reasons of safety, only use the hammer drill when it
is fitted with the auxiliary handle.
Rotate the auxiliary handle anticlockwise until your are in
a safe and comfortable working position.
Then lock the auxiliary handle in this position.
DEPTH STOP (FIG. 5)
Loosen the knob and place the depth stop in the hole.
Adjust the depth stop to the desired depth then tighten
the knob.

MODE SELECTOR (FIG. 6)
Your hammer drill is equipped with a hammer stop facility
for smooth drilling.
To deactivate the hammer action, turn the mode
■
selector (6) clockwise to position (b).
To reactivate the hammer action, the mode selector (6)
■
has to be reset to position (a).
You can use the selector to change modes even when
the hammer drill is operating (at low speed). The selected
mode is only activated once the variable switch (2) is
pressed to start the tool.
Note: Anti-clockwise rotation during impact drilling
damages the drill bit. Deactivate the hammer
action when using a diamond drill bit.
REVERSING THE DIRECTION OF ROTATION
The rotational direction switch (2) can only be activated
when the tool is at a standstill!
The rotational direction switch (2) has two positions:
Clockwise rotation: Set the rotational direction
■
switch (2) to the right position.
Anti-clockwise rotation: Set the rotational direction
■
switch (2) to the left position.
Important
When hammer drilling, you do not need to force
the drill. Too much pressure will place unnecessary
load on the motor. Check the drill bits regularly.
Re-sharpen or replace blunt drill bits.
MAINTENANCE
Unplug the hammer drill before making any
■
adjustment, servicing or cleaning the tool.
Keep your machine clean at all times.
■
Never use caustic agents to clean the plastic parts.
■
At the end of your work, to prevent dust deposits you
■
should use compressed air (max. 3 bar) to clean out
the ventilation slots.
Check the carbon brushes regularly (dirty or worn
■
carbon brushes result in excessive sparking and
speed faults).
