Tool rests Fig 1./No. 4
Tighten the tool rest (4) on the grinding wheel guard
(6) with a knurled-head screw.
The gap between the grinding wheel and the tool rest
should be set to a maximum of 2 mm.
Spark protection (Fig. 2)
Attach the spark protection with a cross-head screw
and washer to the grinding wheel guard. The gap to
the grinding wheel should be a maximum of 2 mm.
Safety screen (Fig. 3, Fig. 4)
Attach the safety screen to the clamping plate with 2
cross-head screws M4, washers and hex-nuts.
The bracket is inserted into the clamping plate and
clamped down with the round-head screw M6 with
washer and nut.
Screw the complete unit to the grinding wheel guard
with U bracket, hex-nut M8 and washer.
The guard can be adjusted appropriately so that the
user's eyes are protected during grinding.
m Electric connection
The installed electric motor is connected and opera-
tional.
The connection complies with relevant VDE and DIN
stipulations.
The customer's mains connection as well as the ex-
tension lead used must comply with these provisions.
Installations, repairs and maintenance on the electri-
cal installation may be carried out by an expert only.
Important notices
If there is a motor overload, it will turn off automati-
cally. After a cool-down period (timing varies), the mo-
tor can be turned on again.
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.
Working with the wet grinder
Put water into the water container.
1
Turn the machine on and leave it running until the
2
grinding wheel is completely wet.
Grind the tool.
3
Empty the water container after grinding. The drain
4
plug is located underneath the water container.
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.
Replacing the wet grinder wheel (Fg. 5)
Drain the water (A).
1
Loosen the 2 cross-head screws (B).
2
Loosen the hex-nut (C).
3
Push the guard up and remove it.
