6.3Function
The belt grinder consists of two functional groups: A grinding
arm [1] with the grinding belt [4] and a polishing station [8] with
polishing wheel [9]. The polishing station is mounted on the left and
the grinding arm is mounted on the right of the housing. The switch
[6] and the four machine bases [7] are fixed to the housing The
specified direction of rotation for the polishing wheel [9] and the
grinding belt is marked on the belt grinder. A water tank [5] is
attached to the grinding arm to cool the tool to be ground. Surplus
water is collected by the sprayhood [2].

7.1Installing the belt grinder
Risk of injuries in the event of slipping, falling or tilting belt
grinder
•Install the belt grinder on a stable table or other stand or
substructure, which has sufficient stability to carry the weight
of the belt grinder.
•The stand must not be mobile or fitted with wheels or castors.
•Install the belt grinder on a flat, slip-proof surface so that the
belt grinder does not slip, tilt or otherwise move when used.
Note the ergonomic requirements
•The machine must be installed in such a way that safe
working is possible for a person in an upright position.
•Ensure good lighting is provided at the workplace.

2 Turn the grinding belt by hand and at the same time check
whether it drifts to the side.
3 If necessary, use the knurled adjusting screw [4] so that the
belt runs in the middle of the deflection pulley [1].

To avoid overheating of the cutting tools the SM-140 belt grinder
has integrated water cooling. The grinding belt dips into a water
bath and through this movement removes a quantity of water,
which is then distributed over the surface of the grinding belt by
a distributing brush [1].

7.7Switching 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 covers 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.
7
•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.

2 Wait until the grinding belt and the polishing wheel stop.
3 After using the machine, swing the water tank back down-
wards.
WARNING
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.

WARNING
Risk of injuries
The blade can cut into the grinding belt and be torn out of
your hand.
•Never grind against the cutting edge.
1 Position the knife at the belt grinder so that the knife
blade [1] points in the direction of rotation of the grinding
belt [2] or the polishing wheel [2].
2 Align the knife blade horizontally so that it is positioned
roughly perpendicular [3] to the grinding belt.
3 Position the knife blade [4] on the grinding belt at an angle
of approx. 15 degrees [5].
4 When grinding, grind the sides of the blade 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.
•Always wet grind cutting tools.
8
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.
