Gear Selection, Mechanical
Two speed ranges can be preselected with the gear
selector 7:
1st gear:
Low speed range; for working with
large drilling diameter.
2nd gear:
Higher speed range; for working with
small drilling diameter.
Actuate the gear selector 7 only when the machine
is at a standstill!
If the gear selector 7 cannot be fully engaged at
standstill, lightly rotate the drive/drill spindle with
the drill bit by twisting the chuck.
Drilling and Impact Drilling
Drilling
Push selector switch 2 to the right.
Impact Drilling
Push selector switch 2 to the left.
Actuate the selector switch only at standstill or just
before the machine comes to a stop.
If the selector switch 2 does not fully engage at
standstill, lightly rotate the drive spindle with the drill
bit by twisting the chuck.
Safety Clutch
If the tool insert becomes caught or jammed, the dri-
ve to the drill spindle is interrupted. Because of the
forces that occur, always hold the power tool firmly
with both hands and provide for a secure stance.
Replacing the Drill Chuck
Loosening the Drill Chuck
(see figure )
D
To unscrew the key type drill chuck 1, position the
open-end spanner (size 17 mm) against the span-
ner flats.
Insert the chuck key into one of the holes and use it
as a lever to release the drill chuck by turning in an-
ticlockwise direction, as if loosening a screw. Loosen
a tightly sitting drill chuck with a light blow on the
chuck key.
Tightening the Drill Chuck
The drill chuck is mounted in reverse order.
Operating Instructions
For drilling in tiles, set the selector switch 2 to the
"Drilling" symbol. Do not switch over to the "Impact
Drilling" symbol until after drilling through the tile,
then work with impact.
Carbide tipped drill bits are required for jobs when
working in concrete, masonry and brick wall.
Optimal drilling progress is achieved when using
carbide tipped drill bits with hexagon clamping
shank (accessories).
Sharpening Drill Bits
For drilling in metal, use only perfectly sharpened
HSS drill bits. The appropriate quality is guaranteed
by the Würth accessories program.
Machine Vice
The machine vice, which is available as an accesso-
ry, enables secure clamping of workpieces. This pre-
vents the workpiece from turning and any accidents
this would cause.
Maintenance and Cleaning
Before any work on the machine itself, pull the
mains plug.
For safe and proper working, always keep the
machine and its ventilation slots clean.
If the machine should happen to fail despite the care
taken in manufacture and testing, repair should be
carried out by an authorized customer service agent
for Würth power tools.
For all correspondence and spare parts orders,
always include the article number on the type plate
of the machine.
