Longitudinal stop Fig.10
To control long work pieces, a longitudinal stopper (9)
can be used.
m Electrical Connection
The installed electric motor is connected and is ready
to work.
The connection complies with the relevant VDE and DIN
regulations.
The customer-side network connection and the used ex-
tension line must comply with these provisions.
Installations, repair, and maintenance work relating to the
electric installation may only be performed by specialists.
• The product meets the requirements of
EN 61000-3-11 and is subject to special connection
conditions. This means that use of the product at
any freely selectable connection point is not allowed.
• Given unfavorable conditions in the power supply the
product can cause the voltage to fluctuate temporarily.
• The product is exclusively intended for use at con-
nection points that have a continuous current-carry-
ing capacity of at least 100 Amper phase.
• As the user, you are required to ensure, in consulta-
tion with your electric power company if necessary,
that the connection point at which you wish to ope-
rate the product meets the specified requirements.
Important notes
The electric motor is designed for operating mode S 1.
If the motor is overload it is turned off automatically.
After a (varying) cooling period the motor can be turned
on again.
Damaged electrical connection cable
The insulation on electrical connection cables is often
damaged.
This may have the following causes:
• Passage points, where connection cables are passed
through windows or doors.
• Kinks where the connection cable has been improp-
erly fastened or routed.
• Places where the connection cables have been cut

due to being driven over.
• Insulation damage due to being ripped out of the wall
outlet.
• Cracks due to the insulation ageing.
Such damaged electrical connection cables must not be
used and are life-threatening due to the insulation dam-
age.
Check the electrical connection cables for damage regu-
larly. Make sure that the connection cable does not hang
on the power network during the inspection.
Electrical connection cables must comply with the ap-
plicable VDE and DIN provisions. Only use connection
cables with the marking „H05VV-F".
The printing of the type designation on the connection
cable is mandatory.
AC motor
• The mains voltage must be 230 V~
• Extension cables up to 25 m long must have a cross-
section of 1.5 mm .

m Maintenance
Slightly lubricate the work table before working. This fa-
cilitates the final cleaning of the work table.
Warning: Exclusively use original spare parts for the main-
tenance/service.
Disconnect the mains plug prior to each intervention in
the grinding machine.
General maintenance notes
The grinding machine must be cleaned carefully after
each deployment. Regularly lubricate all moveable parts.
Treat the work table with a thin layer of automotive type
paste wax. This facilitates the cleaning of the work table.
Help
a-d) Replace all damaged parts before you
use the grinding machine.
e) Contact your local service centre or an
authorized service station. Each at-
tempted repair may cause dangers if not
performed by a qualified expert.
Exert less pressure on the work piece.
Readjust the track.
a) Replace the belt or the disk.
b) Reduce the pressure on the work piece.
