Scheppach SM150LB Original Bedienungsanleitung Seite 28

Do not start grinding until the device has reached its
maximum speed.
Working instructions
• Note that the best results are achieved with low
pressure of the workpiece on the grinding disc, as
then work is done at a constant speed. Excessive
pressure on the workpiece brakes the grinding disc
or it comes to a standstill, this overloads the engine
and does not accelerate the work process.
• For your own safety, always secure small workpiec-
es with a bench vice or screw clamp.
Sanding
• Place the workpiece on the workpiece support (4)
and slowly move it towards the grinding disc (3) at
the desired angle until it touches it.
• To obtain an optimum grinding result and to wear
the grinding disc (3) evenly, the workpiece should be
moved slightly back and forth on the grinding disc (3).
• Always allow the workpiece to cool down.
Attention!
If the disc/wheel should jam while working, please re-
move your workpiece and wait until the device has
reached its maximum speed again.
Changing the grinding disc
Attention: To prevent injuries caused by accidentally
starting the bench grinder, always switch off the device
(switch setting to "0") and disconnect the mains plug
from the socket before changing the grinding disc.
• Loosen the spark protection and protective panel
and pull them out as far as possible, but do not
detach them.
• Loosen the tool support and pull it out as far as
possible.
• Undo the screws of the grinding wheel guard (6) and
remove the guard.
• Remove the outer flange and the old grinding disc,
put on the new grinding disc.
Note:
• Do not remove the cardboard discs attached to the
sides of the new grinding disc, as these help to safe-
guard the flanges' grip against the grinding disc.
• Inspect the new grinding disc for cracks or other
visible damage and discard if necessary.
• Replace the flange and nut.
• Do not overtighten the nut with a spanner, otherwise
the grinding disc may break.

• Re-install the grinding disc guard (6) in the reverse
order.
• Adjust the tool support, spark protection and pro-
tective panel again according to the assembly in-
structions.
11. Electrical connection
The electrical motor installed is connected and ready
for operation. The connection complies with the appli-
cable VDE and DIN provisions.
The customer's mains connection as well as the ex-
tension cable used must also comply with these reg-
ulations.
Damaged electrical connection cable
The insulation on electrical connection cables is often
damaged.
This may have the following causes:
• Pressure points, where connection cables are
passed through windows or doors.
• Kinks where the connection cable has been improp-
erly fixed or routed.
• Places where the connection cables have been cut
due to being driven over.
• Insulation damage due to being ripped out of the wall
outlet.
• Cracks due to the insulation ageing.
Such damaged electrical connection cables must not
be used and are life-threatening due to the insulation
damage.
Check the electrical connection cables for damage
regularly. Ensure that the connection cables are dis-
connected from electrical power when checking for
damage.
Connection type Y
If it is necessary to replace the mains connection ca-
ble, this must be done by the manufacturer or their rep-
resentative to avoid safety hazards.
Electrical connection cables must comply with the ap-
plicable VDE and DIN provisions. Only use connection
cables of the same designation.
The printing of the type designation on the connection
cable is mandatory.
