Inspect bits regularly during use. Blunt
bits should be re-sharpened or replaced.
• Open the chuck (1) by turning the front sleeve
(11) clockwise while simultaneously holding
the rear sleeve (10) or turning it counter-
clockwise and insert the bit into the chuck
opening.
• Tighten the bit by turning the front sleeve (11)
counterclockwise while simultaneously holding
the rear sleeve (10) or turning it clockwise.
Setting depth stop (Fig. A)
• Insert the depth stop (3) in the hole in the side
handle ring.
• Slide the ruler to the desired depth.
4. OPERATIONS
Impact drills require very little operator
pressure. Excessive pressure on the tool
can lead to unnecessary overheating of the
motor, and burning of the driven tool.
The On/Off switch (Fig. A)
• Switch the machine on by pressing the On/Off
switch (5). When you release the On/Off switch
(5) the machine will turn off.
• The rotation-speed can be adjusted by pressing
the On/Off switch (5) harder for raising the
rotation-speed or release pressure for lowering
the rotation-speed.
Lock­on Button (Fig. A)
• You can lock the On/Off switch (5) by pressing
the On/Off switch (5) and then pressing the
lock-on button (4).
• To release the switch-lock; shortly press the
On/Off switch (5) again.
Adjusting of the maximum rotation speed (Fig. A)
• Adjust the speed by turning the speed ad-
justment wheel (6) to the desired maximum
rotation speed.
Switching the direction of rotation (Fig. A)
Do not change the direction of rotation
during use.
• Direction of rotation counter-clockwise: shift
left/right rotation switch (7) to ''L''.
6
• Direction of rotation clockwise: shift left/right
rotation switch (7) to ''R''.
Function selection switch (Fig. A)
In order to avoid damage to the machine,
adjusting the function selection switch (2)
shall only be done when machine is not
running.
• Set the function selection switch (2) to "
for drilling.
• Set the function selection switch (2) to "
for hammer drilling.
Gear selection switch (Fig. A)
In order to avoid damage to the machine,
adjusting the gear selection switch (8) shall
only be done when machine is not running.
• If you set the gear selection switch (8) to
position "1", the drilling speed can be adjusted
between 0 and 1,200 /min.
• If you set the gear selection switch (8) to
position "2", the drilling speed can be adjusted
between 0 and 3,100 /min.
• When the gear selection switch (8) cannot
switch easily between "1" and "2", give the
chuck (1) a little spin by using your hands. This
will help the gears fall into the correct position
and makes switching the gears easier.
User tips
Always use the machine with the side handle firmly
anchored in place - you will not only work with more
comfort, you will also work with more precision.
Caution: drilling bits and hammer drilling
bits can get very hot.
Drilling and hammer drilling
• For large holes, for instance in very hard concrete,
start using a smaller bit for pilot drilling first, then
drill to nominal size.
• Hold the machine firmly with 2 hands. Be aware
the drill can jam and because of that machine
might suddenly turn (Especially when drilling
deep holes).
• Do not apply a lot of pressure on the machine,
let the machine do the work.
