grinding wheel is rotating.
6. Work clothing: Do not wear loose clothing or
jewellery, as such items could become ensnared
in moving machine parts. Wear safety footwear.
Always wear a hairnet!
7. Avoid an unnatural posture. Make sure that you
stand firmly and do not lose your balance.
8. Handle your tools with care.
9. After completion of the grinding work, shut
down the machine.
10.Never leave spanners or wrenches attached to
the tool. Before starting the machine, inspect
the cutter to ensure that all spanners and
wrenches have been removed.
11.Before carrying out any maintenance, retooling
or repair work, disconnect the grinder from the
power supply.
12.Wear goggles while grinding.
13.Depending on the noise level, it might be
necessary to wear hearing protection.
14.Never drill through the motor housing. Attach
the supplied adhesive signs to identify the
machine.
3. Commissioning and
preparation of grinder
Workplace
The working area for the operator must measure
at least 1.5 m2. This area must be exclusively
reserved for grinding work and may not overlap with
any other working area.
The working area must be illuminated with min.
500 lx.

3.1 Commissioning

3.1.1
Prior to commissioning, ensure that the mains
voltage corresponds to the voltage indicated on the
type plate. Switch the machine on and off again to
check whether the motor turns in the direction
indicated by the arrow (if this is not the case,
exchange the connections of the 3 phases in the
plug).
3.1.2
EFA skinning blades can normally be reground
about 10 to 15 times. The profile disk (65) and the
cup wheel (64) consist of a steel body with Borazon-
coated grinding surfaces. The grinding wheels may
therefore not be trued or reworked. Compared with
Schmid & Wezel
D-75433 Maulbronn
other grinding abrasives, the Borazon coating is
extremely hard-wearing and ensures optimised
surface treatment and a long service life of the
skinning blades.
Ensure that the grinder is
switched off when connecting it to
the power mains!
The machine weighs about 17 kg
and must be handled with the
necessary caution when being
installed. When lifting and
positioning the grinder or the accessory case
(14 kg), observe a good posture.
Check whether the blades can be reground, i.e.
whether the tooth gullet corresponds to the
minimum bearing face.
Check the blade bushing dimensions, using a
new connecting rod. The connecting rod must
always move freely.
Ensure that the blade bushing is properly
inserted in the blade.

3.2 Machining of blade pairs

When replacing blunt skinning blades with sharp
ones, always exchange the blade pair and not just
single blades. They blades must also be ground in
pairs!

3.3 Cleaning of skinning blades

Clean the blades with hot water and a brush. If
necessary, use a concentrated detergent to remove
persistent dirt. Do not use hard or abrasive
materials to remove residue.

3.4 Inspection

3.4.1 Checking blade bushing
Insert a new connecting rod into the blade bushing.
If there is excessive play, the blade bushing must be
replaced. To replace the blade bushing, insert the
support (90) into the flattening block (86). Place the
skinning blades with the connecting ends facing
down into the borehole of the support (90). Drive
the blade bushing from the skinning blade, by
tapping it with a hammer and a suitable punch (fig.
7).
