General safety advice / UseGeneral safety advice
Make sure that the grinding tools are
appropriate in line with the instructions
of the manufacturer.
Check the grinding stone before using
it; do not use any broken, cracked or otherwise
damaged goods.
Make sure that a grinding tool is correct-
ly fitted and fastened before using it.
Place the grinder in a safe place and allow it
to run idly for 30 seconds. Stop it immediately if
considerable oscillations occur or if defects are
observed. If this occurs, check the machine to
find out the cause.

Sharpening a drill
NOTE: Badly damaged drills should first be coarsely
sharpened on a sharpening block.
Fully lower the sharpening stone. To do this turn
the rotary switch
1
in the DOWN direction
as far as it will go.
Insert the drill into the smallest suitable drill
guide
11
on the drill sharpener. The exact size
(Ø) of each drill guide
11
is shown by the ad-
jacent lettering (3 to 10).
Press the ON / OFF switch
4
into position “I”
to switch on the device.
Turn the rotary switch
1
in the UP direction
until you hear a grinding noise.
NOTE: The rotary switch
1
controls the posi-
tion of the sharpening stone in the sharpening
head housing and therefore the pressure of the
sharpening stone against the drill. The further
you turn the rotary switch
1
in the UP direction
,
the greater the pressure. Ensure that you do not
turn the sharpening stone too far up. Otherwise
the sharpening stone could strike the housing.
Turn the drill under slight pressure loosely and
quickly to and fro between the left and right stops
about 10 times (with small drills about 5 times).
Pull the drill out, turn it through 180° (horizon
tally)
and insert it again until it meets the sharpening
stone.
If necessary repeat whole process until both
cutting edges of the drill are sharp. Polish so the
angle (
) between the two cutting edges (b) is
118°. The two cutting edges (b) must have the
same angle to the drilling axle (a) and have
the same length so the drill runs centred (see
figures below).
(b)(b)
(a)
=118°
Press the ON / OFF switch
4
into position “0”
to switch off the device.
Q
Replacing the
sharpening stone
RISK OF INJURY! Before you
carry out any work on the device, always pull the
mains plug out of the mains socket. Replace the
sharpening stone if it is worn out or damaged
(deteriorating, irregular sharpening performance,
broken stone). A Phillips screwdriver is required for
this step.
Screw the three screws
3
out of the sharpening
head cover
2
and remove the cover
2
, refer
to Fig. A.
Take out the sharpening stone
5
.
Clamp the sharpening stone
5
in a vice. Re-
lease the threaded connection
7
, which holds
the sharpening stone
5
on to the sharpening
stone holder
9
, using a 23 mm open spanner
or a wrench socket, see Fig. B.
