Operation
Switching ON/OFF
1. To switch on the impact drill, press the ON/OFF trigger (6). Release the
trigger to switch it off.
2. The ON/OFF trigger can be locked in the pushed (ON) position by pressing
the lock-on button (9). The lock-on button automatically releases when the
ON/OFF trigger is pressed again.
Speed Adjustment Wheel
Depending on the pressure applied on the ON/OFF trigger, the impact drill
operates at a variable rotation speed from 0 to 3000 revolutions per minute.
Light trigger pressure results in a low rotation speed and smooth controlled
starting of the drill.
The required rotation speed for drilling depends on the material being
processed. It is best selected by a practical test. Always use a speed which is
high enough to prevent the machine from stopping due to overload. The
maximum speed can be adjusted with the speed adjustment wheel (5).
Changing the Rotating Direction
The switch for clockwise/counter clockwise operation (4) may only be operated
when the motor is at a complete standstill. When the ON/OFF trigger (6) is
depressed, the rotational direction switch (4) is blocked.
Clockwise rotation: for drilling and fastening of screws
Counter clockwise rotation: for removing screws
Drilling/Impact Drilling
The drilling/impact drilling selector (2) may only be operated when the motor is
at a complete standstill. This selector (2) is located on the top of the impact
drill.
For impact-drilling push the switch towards the hammer
icon.
For drilling push the switch towards the drill
icon.
