Important notes
Damaged electrical connection cables
Insulation damage often occurs with electrical con-
nection cables.
Some causes are:
• Pressure points, especially when electrical connec-
tion cables are run through window or door cracks.
• Kinks caused by improper handling or mowing of
the electrical connection cables.
• Cuts resulting from being run over
• Insulation damages caused by pulling the cable out
of wall sockets.
• Cracks resulting from aging of the insulation.
Such insulation damaged electrical connection cables
cannot be used and are, as a result of their insulation
damage. LIFETHREATENING!!
Check the electrical cable connections on a regular
basis. When checking the cables, make sure that the
cables are not stuck to the electrical network.
Electrical cable connections built with seal contacts
must meet the relevant VDE and DIN requirements.
Only use electrical cable connections with a rating of
at least H 07 RN or a rubber sheathed cable.
The type rating of the connection cable must be print-
ed on the cable.
Single-phase motor
• The mains voltage must comply with the specifica-
tions on the motor nameplate.
• Extension cables up to 25 m in length must have a
cross section of at least 1,5 mm² , above 25 m at
least 2,5 mm²
• Mains fuse protection is 10 Amps slow-blow.
In accordance with safety regulations, the motor is
equipped with a switch featuring an integrated pro-
tective circuitbreaker, which cuts off the current in the
event of
overload.
Overload may be caused by the following:
• longer-duration blockage of the knife disc
• alternately switching on/off of the motor in rapid
succession
In the event of a blocked knife disc, remove the cause
to the overload. Disconnect the mains plug. After a
short cooling-off time , switch back on the motor.
