USE aND OPEraTiON

domestic or hobby use only.
The manufacturer and the importer do not recommend
to use this equipment under extreme conditions and at
high loads. Any other additional requirements must be
agreed upon by the manufacturer and the buyer.
Initial use Grinding drills
Note: First rough grind severely damaged drills with a
grinding block.
Fully lower the brick. To do so, turn the dial 1 all the
way in the DOWN ▼ direction. Insert the drill into the
smallest drill guide 11 on the sharpener it will fit. Ple-
ase refer to the markings (3 to 12) for the exact sizes
(Ø) of the respective drill guides 11 .
Set the ON/OFF switch 4 to position „I" to switch on
the product.
Turn the dial 1 in the UP ▲ direction until you hear a
grinding noise.
Note: The dial 1 controls the position of the brick inside
the grinding head, thus the grinding pressure the brick
applies to the drill. The more the dial 1 is turned in the
UP ▲ direction, the greater the grinding pressure.
Be sure not to raise the brick too high. The brick may
otherwise get in contact with the housing.
Loosely and quickly rotate the drill back and forth abo-
ut 10 times between the left and right stop, applying
light pressure (small drills about 5 times).
Slightly pull out the drill, turn 180° around its own axis
and reinsert up to the brick. If necessary, repeat the
entire process until both faces are sharp. Polish so the
angle ( ) between the two cutting edges (b) is
118°. Both cutting edges (b) must have the same angle
to the drilling axle (a) and have the same length for the
drill to run centred
Set the ON/OFF switch 4 to position „0" to switch off
the product.
