Operation; Cleaning And Maintenance; Electrical Connection - Scheppach SM150LB Original Instruction Manual

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
begin 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
grinding wheel (3) at the desired angle to the point
where workpiece and grinding wheel make con-
tact.
• 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 ac-
cidentally 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.
• Undo the screws of the grinding wheel guard (6)
and remove the guard.
• 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.
• Re-install the grinding wheel guard (6) in the re-
verse order.
• Mount work rest, spark guard and eye shield ac-
cording to installation instructions.

9. Cleaning and maintenance

Always pull out the mains power plug before starting
any cleaning work.
Cleaning
• Keep all safety devices, air vents and the motor
housing free of dirt and dust as far as possible.
Wipe the equipment with a clean cloth or blow it
with compressed air at low pressure.
• We recommend that you clean the device immedi-
ately each time you have finished using it.
• Clean the equipment regularly with a moist cloth
and some soft soap. Do not use cleaning agents or
solvents; these could attack the plastic parts of the
equipment. Ensure that no water can seep into the
device. The ingress of water into an electric tool
increases the risk of an electric shock.
Maintenance
There are no parts inside the equipment which re-
quire additional maintenance.
