7.7 Switching on the belt grinder
WARNING
Risk of injury due to damaged or incorrectly mounted machine parts
Using the belt grinder with damaged electric parts or power cables can cause
injuries due to electric shocks or malfunctions.
Damaged grinding belts can be partly spun off the machine.
-
Missing or damaged coves expose rotating parts and can cause injuries due to crushing and drawing in. Check the belt grinder for damage before each use, in particular:
– the grinding belt,
– the polishing wheel,
– the power cable,
– correct assembly and covering function of all covers and the housing,
– the function of the switches. -
Replace damaged parts before using the belt grinder again.
CAUTION
Risk of injuries due to poor health of the operator
Lack of concentration, over-tiredness, illness, drunkenness or leg or arm
disabilities, as well as mental disabilities, cause a high risk of injuries.
- People who work at the belt grinder must be healthy and capable of concentrating.
- Before starting work at the belt grinder, ensure you are in a stable position in which you can maintain your balance without any effort.
- When grinding and polishing, do not look away from the belt grinder and workpiece.
CAUTION
Risk of injuries on touching the belt grinder
Touching the grinding belt or polishing wheel while the belt grinder is
switched on causes injuries.
- Do not touch any abrasives while the belt grinder is switched on.
- Do not use any objects to brake rotating abrasives.
- The switched on belt grinder must be inaccessible to persons not working at the belt grinder, especially to children.
- Before leaving the work area, switch off the belt grinder and remove the mains plug from the socket.
WEAR SUITABLE PROTECTIVE CLOTHING
Rotating machine parts can catch unsuitable clothing or long haAbrasive
particles spun off the machine or loud machine noises can damage eyes and
ears.
Sharp and hot workpieces can cause injuries to hands.
Rotating abrasives can pull off pieces of clothing.
- Ensure good lighting is available,
- wear tight-fitting clothing,
- do not wear jewellery,
- wear a hair net on long hair,
- wear safety glasses or goggles,
- wear hearing protection,
- wear suitable protective gloves,
- do not touch rotating machine parts with parts of the body covered with fabric.
Switch on the belt grinder as follows:
- Insert the plug into the socket.
- Check the alignment of the belt running (see “Adjusting the grinding arm angle” on page 18).
- Press the green button (Switches) at the switch.
- Check the direction of rotation when starting up the belt grinder.
– The direction of rotation is given by arrows on the covers.
7.8 Switching off the belt grinder
- Press the red switch (Switches, Item. [1]).
- Wait until the grinding belt and the polishing wheel stop.
DANGER
Risk of electric shock
If the plug is removed from the socket by pulling the power cable, the connection between the plug and cable can be damaged and is therefore a substantial source of danger.
When disconnecting the power connection, hold onto the plug and pull it out of the socket.
3 Pull the mains plug out of the socket.
4 Cleaning the belt grinder.
WARNING
Risk of injuries after thoughtless switching on of the belt grinder
If the belt grinder is left unattended after grinding work, there is a risk of
the belt grinder being switched on by unauthorised or thoughtless persons.
- After carrying out grinding work, never leave the belt grinderunsupervised unless the mains plug has been disconnected
- Store the belt grinder in a safe place, to which unauthorisedpersons do not have access.
Machining Workpieces

- Grinding with underlay for straight grinding
- Grinding on the free belt for convex grinding (also called crowned grinding)
NOTE
Dirty knives can irreparably damage the grinding belt and polishing wheel. The
surfaces can heat with long-term use.
- Only machine clean knives.
- Switch off the belt grinder after 30 minutes at the latest.

Positioning angle for the knife blade (15°)
-
Position the knife at the belt grinder so that the knife edge [1] points in the direction of rotation of the grinding belt [2] or the polishing wheel [2].
-
Align the workpieces horizontally so that they are positioned roughly perpendicular [3] to the grinding belt.
-
Position the knife blade [4] on the grinding belt at an angle of approx. 15 degrees [5].
-
When grinding, grind the sides of the workpiece alternately, until a burr has formed over the entire area.
NOTE
Workpieces heat during grinding
An over-heated blade can anneal (loss of hardness) and stress cracks can form
in it.
- After several grinding passes, cool the workpiece in a water bath.
NOTE
If the blade has become thicker as a result of frequent grinding, the blade
thickness can be reduced again by grinding the flat sides.
8.2 Polishing workpieces

Positioning angle relative to the polishing wheel (approx. 20°)
1 Hold the polishing paste against the polishing wheel while it is running,
2 Position the knife slanted relative to the running direction,
3 Position the knife at the polishing wheel at a more obtuse angle than for grinding,
4 Grind the knife until the burr has been completely removed and the surface has the required polish.
5 Polish both sides of the blade alternately.
