Grinding with the dry
grinding disc
• Place the workpiece on the workpiece
support (
6) and slowly bring it to its
desired angle on the dry grinding disc
(
5).
• Move the workpiece slightly from side
to side in order to achieve an optimal
grinding result. This way, the dry
grinding disc is worn uniformly. Oc-
casionally, allow the workpiece to cool
down.
• Fold the spark protection device (
2)
downwards while grinding in order to
avoid injury from sparks.
Grinding with the wet
grinding disc
• Check the water level in the water
tank: The wet grinding disc (
1) is to
be submerged in water up to the water
level mark
on the water tank (
13).
• Stand in front of the wet grinding disc
(
1).
• Hold the workpiece with both hands
and lower it slowly onto the wet grind-
ing disc.
• The workpiece can also be supported
on the teeth of the water tank (
13).
Change grinding disc
Information on replacement:
• Never operate the device without
protective equipment.
• Ensure that the rotation speed
stated on the grinding disc is the
same or higher than the nominal
rotation speed of the device.
• Ensure that the grinding disc
dimensions match those of the
device.
• Only use flawless grinding discs
(sound test: an undamaged grind-
ing disc hanging freely on a
string will result in a clear sound
if it is tapped with a plastic ham-
mer).
• Never re-drill a locating hole
which is too small to make it
larger.
• Never use separate bushings or
adapters in order to make grind-
ing discs whose hole is too large
fit the device.
• Do not use any saw blades.
• To clamp the grinding tools only
use the clamping flange provid
-
ed. The pads between the clamp
-
ing flange and the grinding tools
must be made of elastic materials
e.g., rubber, soft cardboard etc.
• Always reassemble the device
completely after replacing the
grinding disc.
Switch the device off and remove
the mains plug.
Allow the device to cool down.
Wear protective gloves when
changing the grinding discs in or-
der to avoid cutting damages.
Change dry grinding disc:
1. Loosen the fixing screws and re
-
move the dry grinding disc cover
(
4) from the protective hood
(25).
2. Unscrew the grinding disc
nut (22) with a screw wrench
(AF 19 mm) and hold against
