Note! If the grinding wheel has been in the water for
a lengthy period, distortion can occur and the grinding
wheel may no longer rotate smoothly.
Replacing the grinding wheel
WARNING: : In order to prevent injury by accidentally
starting the double-ended bench grinder, the device
must be turned off before replacing the grinding wheel
(switch position „0“) and the power plug disconnected
from the socket.
• Loosen the spark protection and safety screen and
pull them out as much as possible but do not re -
move them.
• Loosen the tool rest and pull it out as much as pos -
sible.
• Remove the screws and pull off the end plate.
• Remove the outer flange and the old grinding wheel,
then attach the new grinding wheel.
Note:
• Do not remove the cardboard discs attached to the
sides of the new grinding wheel because they aid
the secure grip of the flange against the grinding
wheel.
• Check the new grinding wheel for cracks or other
visible damage and dispose of it if applicable.
• Re-attach the flange and nut.
• Do not tighten the nut too much with a spanner be -
cause the grinding wheel may break.
• Attach the end plate again.
• Adjust the tool rest, spark protection and safety
screen again according to the assembly instruc -
tions.
• Never sharpen or grind anything made of aluminum.
• Never sharpen or grind anything which cannot be
held correctly because of the size.

Operating instructions
You must observe the following points before commis -
sioning the double-ended bench grinder:
• Activate the main switch. Wait until the grinding
wheel has reached its maximum speed. Then you
can start grinding.
• Hold the work piece firmly on the tool rest and move
it slowly and steadily towards the grinding wheel.
• Grinding can lower the speed of the grinding wheel.
Reduce the pressure a little until the wheel has re -
turned to its full speed.
WARNING:
• Small work pieces should be held with pliers or a
similar tool.
• Only ever grind on the face of the grinding wheel,
never on the sides.
• As most materials get hot during grinding, you must
be very careful with the work piece.
