2. Construction
This grinder is a surface cooled electric tool with high overloading
resistance and of sturdy construction. The tool offers the
advantage of total enclosure, eliminating wear caused by ingress
of grinding dust. The switch is built into the dustproof handle.
For safety reasons the machine must be earthed (according to
VDE regulation 0100
§
15) using the designed earth wire, one
end fastened to the connection plate of the switch, the other end
connected to the earth screw of the plug.
Types MSho 852 K must not be earthed.
3. Connection and Operation
Operating voltage and frequency must correspond to the voltage
and frequency marked on the rating plate. Provide overload
protection to match the rated current.
. For good installation of high frequency, we draw your attention
to our installation instructions for High Frequency Transformers
(BE 22) .
Switch must be in the "Off" position when connecting.
Check that tool rotates in direction marked by arrow on the
machine otherwise the flange may become loose. On putting

tool into service, switch on briefly only to check rotation. If it
does not follow arrow, reverse by changing over two leads in
the plug.
Do not exceed the dimensions of grinding wheels stipulated.
4. Maintenance and lubrication
The grinder requires proper maintenance. Before carrying out
any maintenance work always remember to pull out the plug.
In order to prevent accidents check cable at regular intervals.
To replace cable see paragraph 5 (3).
After fitting a new cable check all conductors as well as earth
wire.
Every 900 duty hours the grinder should be completely dis-
mantled as described under paragraph 5 and all parts must be
thoroughly cleaned.
Please be sure that all electric parts are only cleaned dry.
The gear needs particularly thorough lubrication. Rinse ball
bearings in clean solvent, then pack them with fresh grease.
