Loosen and remove the two disc lock nuts (ba). To
loosen the nut, you may need to hold the disc and
hit the nut hard with a rubber mallet, lower the large
convex washer (bb), paper pad (bc), and remove
the discs (bd). Note: The nut on the right side of
the grinder has a standard clockwise thread (turn it
counterclockwise to loosen it). The nut on the left side
of the grinder has a counterclockwise thread (if you
want to loosen it, turn it clockwise). Install the new
discs in the same way, making sure that both convex
washers are turned correctly, check the paper washer
(bc abe). If it is damaged, replace it with a new paper
pad. Hold the disc and tighten the nut firmly. When
doing this, make sure that you do not overtighten the
nut!
Note: Replace flanges with original parts only.
Caution: Excessive tightening can
cause the grinding wheel to break.
Installation and adjustment of spark arresters (C)
The blade is equipped with a spark arrestor (4), which
protects your eyes and hands from sparks flying away
from the workpiece. Never work without the spark
arrestor fitted.
The position of the spark arrestor must be adjusted
regularly to adapt to the wear of the grinding wheel.
Attach the spark arrestor (4) to the disc cover (3) with
a screw.
Set the distance between the spark arrestor and the
grinding wheel (2) to the lowest possible value, to a
maximum of 2 mm.
Tighten the spark arrestor bolt.
Slide the transparent screen (5) forward.
Tighten the nut.
Workpiece support adjustment (D)
The grinder is equipped with a workpiece support on
both wheels. The position of each workpiece support
must be adjusted regularly to accommodate the wear
of the grinding wheel.
Loosen the adjusting screw.
Set the distance between the workpiece sup-
port (6) and the grinding wheel (2) to the
lowest possible value, up to a maximum of
2 mm. Finally, tighten the adjusting screw.
Dry grinding
Dry grinding is suitable for rough grinding.
Cool the ground tools regularly with coolant when
grinding.
The blade guard and support must be checked regu-
larly to prevent excessive blade wear.
How to turn the grinder on and off
-To turn on the grinder, set the switch (1) to the I I
'position.

Tips for work
Your grinder is suitable for sharpening tools, such as
drills, chisels, face turning tools, eg for removing ma-
terial residues from tool edges; for material removal,
but it is not a tool for hard work. It is designed prefer-
ably for lighter home and
hobby use. Always use a coarse-grained grind-
ing wheel for coarse grinding, i.e. to remove large
amounts of material. Use a medium-thick grinding
wheel to achieve a finer surface. If the grinder is used
to grind soft metals such as aluminum, the wheel will
clog quickly and need to be replaced. Always let the
grinder do its job, do not overload it, do not apply
excessive pressure to the blade / cutting tool. Try to
use a knife support to support and guide the edge. Do
