ASSEMBLY
Work Rests (Fig. 1, Nr. 4)
Install the work rest with a star grip screw and a washer
to the wheel guard. The distance between wheel and
work rest should not exceed 2 mm.
Spark Guards (Fig. 2)
Install the spark guard with a cross-head screw and a
washer to the wheel guard. The distance to the wheel
guard should not exceed 2 mm.
Wheel Guards (Fig. 3, Fig. 4)
1 Install the eye shield with 2 cross-head screw n M4, 2
washers and 2 hex nuts to the clamping plate.
2 Lead the handle into the clamping plate and fix it with
a flat head screw M6, a washer and a nut.
3 Fix the complete unit to the wheel guard with U-handle,
hex bolt M6 and a washer.
The guard is individually adjustable, as to protect the us-

8. Operation

On/Off switch (8)
• To switch on the equipment set the On/Off switch (8)
to position On.
• Move the On/Off switch (8) to position Off to switch
off the equipment.
After switching on, wait for the equipment to reach its
maximum speed of rotation. Only then should you be-
gin with the grinding.
Work practice
• Exert only moderate pressure on the workpiece so
that it can be machined at constant speed.
• Instead of accelerating your work, high pressure will
cause the drive unit to slow down and even stop,
thus overloading the motor.
• For your own safety, it is essential to secure small
workpieces with a screw clamp or vise.
Grinding
• Place the workpiece onto the workpiece support (4)
and slowly guide the workpiece towards the grind-
ing wheel (3) at the desired angle to the point where
workpiece and grinding wheel make contact.
• Move the workpiece slightly back and forth to pro-
duce an optimal grinding result. This way the grind-
ing wheel (3) will be evenly worn. Allow the work-
piece to cool down occasionally.

Important!
If the grinding wheel becomes jammed during op-
eration, remove the workpiece and wait until the tool
reaches its top speed again.
CHANGING THE GRINDING WHEELS
IMPORTANT NOTE: In order to prevent injuries from
accidentally starting the machine the machine's main
switch must be turned off before changing a grinding
wheel. Pull power plug!
• Loosen the spark gard and the eye shield and pull out
• as far as possible. Do not remove these parts!
• Loosen work rest and pull out as far as possible.
• Dissemble screws and pull off end plate.
• Take off outside flange and the old grinding wheel,
then assmeble the new one.
Important note:
• Do not remove the pieces of card board on the sides
of the wheel, as they are intended for strengthening
the grip of the Flange against the grinding wheels.
• Examine the new grinding wheels on cracks or other
visible damages and dispose if necessary.
• Mount flange and nut again.
• Do not tighten the screw by force. This can cause the
grinding wheel to break.
• Mount end plate.
• Mount work rest, spark guard and eye shield accord-
ing to installation instructions.
Using the grinding wheel dresser
The grinding wheel dresser is a tool for straightening of
grinding wheels.
• Press lightly against grinding wheel – without cre-
ating sparks. Move the dresser sideways over the
entire width of wheel.
m Attention! Always wear safety goggles.
