Defective electrical connection cables
Electrical connection cables often suffer insulation dam-
age.
Possible causes are:
• Pinch points when connection cables are run through
window or door gaps.
• Kinks resulting from incorrect attachment or laying of
the connection cable.
• Cuts resulting from running over the connecting cable.
• Insulation damage resulting from forcefully pulling out
of the wall socket.
• Cracks through aging of insulation.
Such defective electrical connection cables must not be
used as the insulation damage makes them extremely haz
ardous.
Check electrical connection cables regularly for damage.
Make sure the cable is disconnected from the mains when
checking.
Electrical connection cables must comply with the regula-
tions applicable in your country.

Only a qualified electrician is permitted to connect the ma-
chine and complete repairs on its electrical equipment.
In the event of enquiries please specify the following da-
ta:
• Motor manufacturer
• Type of current of the motor
• Data recorded on the machine's rating plate
• Data recorded on the switch's rating plate
If a motor has to be returned, it must always be dispatched
with the complete driving unit and switch.
Maintenance
• Overhauls, maintenance work, cleaning, as well as the
elimination of any malfunctions must only be undertak-

• All protective and safety equipment must be reinstalled
immediately upon completion of any repair or mainte-
nance work.
• Clean and lightly oil the spindle thread of the tool holder
when changing tools.
• When possible, the tail stock sleeve should be removed
by unscrewing it, cleaned and then sprayed with a dry
lubricant. Grease the threaded spindle.
• Check the eccentric clamp of the tailstock as well as the
tool holder and adjust if necessary. In addition, tighten
the hex nut under the bracket.
• Check the drive belt and replace when necessary.
