The machine has 2 drill speeds, which can be adjusted by sliding the gear switch (8) forward or
backwards. The number on the gear switch (8) shows which position is chosen.
The on/off switch (5) is used for activating the machine and adjusting rotation speed.
Position 1: For slow drilling, large drilling diameter or screw driving. The machine has high power
at a low speed.
Position 2: For fast drilling or small drilling diameter.

OPERATION
Never switch gears when the motor is running, this will damage your machine.
Never put switch in the middle between both positions, this will damage your machine.
• Pressing the on/off switch (5) will activate the machine, the further the switch is being pushed,
the faster the drill will turn.
• Releasing the on/off switch (5) will stop the machine.
• Move the direction reversing switch (9) to the middle position to lock the movement of the on/off
switch.
The machine has 21 different torque settings and a special drill mode to set the power being
transmitted to the chuck. By rotating the torque adjustment ring (6), screws can be driven to a
predetermined depth, which is ideal for repetitive work. The higher the number, the more torque will
be transmitted.
Adjusting the torque (Fig. A)
• Select a low setting for small screws or soft work material.
• Select a high setting for large screws, hard work materials and when removing screws.
• You should preferably choose a setting as low as possible when driving screws. Select a higher
setting if the motor slips before the screw is fully tightened.
• For drilling, turn the torque adjustment ring (6) to the setting for drilling (
it counterclockwise.
) by fully turning
