9. Troubleshooting
By purchasing this cordless impact screw driller, you have acquired a product designed to the state of the art and
operationally reliable. Nevertheless, problems or errors may occur. The following contains descriptions for the removal
of possible interferences.
Always observe all safety information and all other information in these operating instructions!
Problem
Solution aid
No function.
•
Check the rechargeable battery condition and recharge the recharge-
able battery.
•
Check that the rechargeable battery has been inserted correctly and
has latched.
•
The overload or overtemperature protection may have been tripped.
Switch off the cordless impact screw driller and wait until the device has
cooled off before using it again.
The on/off switch cannot be pushed.
•
The on/off switch is blocked (activation lock) for reasons of safety when
the rotating direction switch is in the middle position. Push the rotating
direction switch out of the middle position.
No drilling progress is evident when
drilling, the drill will not enter the
workpiece.
•
Check the rotating direction of the drill. Move the rotating direction
switch to the proper position.
•
Use a new, sharp drill.
•
Use a drill that is suitable for the material you want to drill a hole into
(wood, metal or stone drill).
•
Select the proper speed for the drill depending on the material into
which you want to drill a hole.
•
When drilling into stone/concrete, you need to select the hammer icon
with the torque setting ring.
The cordless impact screw driller rat-
tles when loosening or tightening a
screw or when drilling.
•
Adjust the torque setting ring, so that a higher torque is available for
turning in screws (higher set value).
•
When drilling holes, choose the position with the drill icon at the torque
setting ring; the same applies to turning out of screws.
The drill chuck turns too slowly or too
fast.
•
Check the settings of the slider for the two-speed gear and select a
different gear (release the on/off switch first and wait until the drive has
stopped completely).
The drill chuck turns, but the drill (or a
bit for screwing) does not (tool slips).
•
Check if the drill chuck is tightened.
•
The clamping area of the drill chuck is too small. Push the tool more
deeply into the drill chuck.
