Use
The drill is universally applicable for percussion drilling in
rock, drilling and putting screws into wood, metal, and
synthetics, and for tapping.
Safety instructions and prevention of accidents
Before operating the machine, please read through
the operating instructions completely, follow the Safety
Instructions in this manual as well as the general Safety
Instructions for Power Tools in the accompanying
booklet.
Caution!
●
Beware of jamming. The machine may jam, for ex-
ample, when the machine is at an angle or when the
drill bit comes into contact with reinforcing steel!
●
Before mounting tools in the drill chuck or spindle,
always move the reversing switch (3) to the middle
LOCK position, or disconnect the machine from the
power supply, or remove the mains cable module
(7) from the grip using the locking device button (8).
●
Do not work with materials containing asbestos!
●
Outside power sockets must be protected with re-
sidual-current-operated circuit-breakers (r.c.c.b.).
●
Do not drill holes into the housing to label the ma-
chine. The protective insulation will be bridged.
Please use self-adhesive labels.
●
Always lead cables away towards the back of the
machine.
Double insulation
Our equipment is designed in accordance with European
regulations (EN standards) for the utmost safety of the
user. Machines with double insulation always carry the in-
ternational
symbol. The machines do not require eart-
hing. A two-core cable is sufficient.
The machines are interference-suppressed in accordance
with EN 55014.
Initial operation
Before the first operation check that the mains voltage cor-
responds to that given on the machine nameplate.
Trigger switch with button for continuous operation
The machine is set in operation by pressing in the handle
switch (1). The small holding button (2) on the side of the
switch is pressed in for continuous operation. To release
the continuous operation merely depress the switch, which
makes the holding button spring back automatically.
Electronic speed control
This machine has an integrated full wave electronic control
circuit switch.
The required speed may be selected with the adjusting
wheel (e.g. for serial screw drilling or for cutting threads).
The switch is lockable in every position.
Position A = lowest speed
Position G = highest speed
Ensure that the drill is not allowed to jam for longer
than 2–3 seconds. Longer jamming can lead to motor
damage.
Important!
Continuous operation under strong load and low speed
can overheat the motor. Allow the motor to cool down
in no-load when set at a high speed!
Torque-sel electronic safety system
(Model 1050 SXC only)
The integrated full wave electronic system with tachometer
maintains a constant rpm speed. The system’s preselect-
able power regulation (torque selection) allows the torque
to be regulated to meet different requirements, for exam-
ple, in the case of serial screw drilling. Regulate the torque
with the adjustment wheel (4) on the grip.The torque level
is determined by several factors, including the hardness of
the material being worked, and the length and diameter of
the screws being used. As a result it is necessary to adjust
the torque initially by making a few test screw drillings.
Recommendation
Position 1
= least torque
Position 10 = greatest torque
The electronic system also has a gradual start up feature.
Even if the trigger-switch is fully depressed, the machine
willl only reach its full rpm speed after approx. 1 second.
This permits smooth drilling even when working with sensi-
tive materials.
The integrated electronic safety system prohibits start up
in the case that the machine is plugged into the power
supply with the trigger-switch locked in the ON/OFF posi-
tion. Should this occur, unlock the switch and start in the
normal fashion.
