Technical Data
Assembly
Adapting the Drive Element (see figure A)
Before mounting for the first time, adapt the length of the
drive element
1
to your drill.
– Shorten the drive element
1
with a metal saw, ensuring
that clearance
a
in the figure amounts to 110 mm
(4 5/16").
Should the drive element
1
be too short for your drill, use a
commercially available M8 hexagon bolt with the appropriate
length.
Mounting the Drill Bit Sharpener (see figure B)
f
Before any work on the machine itself, pull the mains
plug.
f
The drill bit sharpener may only be used when mounted
to a drill. It is not approved for manual sharpening of
drill bits.
Danger of injury.
– When an auxiliary handle is mounted on the spindle collar
2
of your drill, remove the auxiliary handle first.
– Clamp the drive element
1
into the chuck of your drill.
For this, observe the operating instructions of your drill.
– Press the drill bit sharpener firmly against your drill and
tighten clamping screw
3
at the same time.
The clamping screw must be fastened against the spindle
collar
2
of the drill, not against the drill chuck.
Operation
Working Advice
Sharpening Drill Bits (see figure C)
– Pre-sharpen heavily damaged drill bits first using a bench
grinder.
– When the speed of your drill can be regulated, set the
speed to 2000 to 3000 min
-1
.
On impact drills, set the operating mode to “drilling with-
out impact”.
