• Tears from ageing insulation;
• Kinks due to inappropriate attachment or guidance
of the connection.
The machine connection cables have to be at least
type H05RN-F and three-core. Printing the type
designation on the connection is the law. Only ever
buy cables with the designation marked! The plugs
and coupling boxes on the machine connection ca-
bles have to be made of rubber and be protected
against spray water. The cables must not be over-
long. Longer cables require larger conductor cross
sections. Power cords and connection cables have to
be checked regularly for damage. Make sure that the
connections are turned off during checking. Unwind
the connection cable fully. Also check cable inputs,
on plugs and coupling boxes, for kinks.
13. Disposal and recycling
The disposal notices are presented by pictograms
on the machine or on the packaging. A description
of the individual meanings can be found in Chapter
„Description of symbols on the machine“.
Disposing of transport packaging
The packaging protects the machine from damage
during transport. The packaging material is usually
chosen for factors of environmental friendliness and
disposal. It can therefore be recycled. Returning the
packaging to the material life cycle saves raw mate-
rial and reduces waste.
Packaging parts (e.g. plastic sheets, Styropor®) can
be dangerous for children. Risk of choking! Store
packaging parts beyond the reach of children and
dispose of them as soon as possible.
age.
Regularly check electrical connections for damage.
Make sure the cable is not connected to the mains when
checking.
Electrical connections must comply with relevant VDE
and DIN stipulations. Only use connections marked
H05VV-F.
Printing the type designation on the connection cable
is the law.
AC motor
• The power voltage has to be 220 – 240 V ~.
• Extension leads up to a length of 25 m must have a
cross section of 1.5 square mm.
Connections and repairs to the electrical equipment
must be carried out by a trained electrician.
If there are any questions, please provide the follow-
ing data:
• Motor’s type of power
• Data from the machine’s rating plate
• Data from the motor‘s rating plate
Machine connection
Only ever use machine connection cables which are
not damaged. The machine connection cable must
not exceed 50 m because otherwise the performance
of the electric motor is reduced. The machine con-
nection cable must have a cross section of 3 x 1.5
mm. Machine connection cables are particularly of-
ten subject to insulation damage. Causes include:
• Cuts when the connection is run over;
• Pinching when connections are guided through
windows and doors;
14. Troubleshooting
Problem Possible cause Solution
Motor does not work. Motor, cable or plug faulty, fuses blown Have the machine checked by a specialist.
Never repair the motor yourself. Danger! Check
fuses and replace, if required.
The motor starts
slowly and does not
reach operating speed.
Voltage too low, winding damaged,
capacitor blown
Have the voltage checked by the electricity
board. Have the motor checked by a specialist.
Have the capacitor replaced by a specialist.
Motor too noisy Winding damaged, motor faulty Have the motor checked by a specialist.
Motor does not reach
peak performance.
Mains electric circuit is overloaded (lamps,
other motors etc.).
Do not use other machines or motors in the
same electric circuit.
Motor overheats
easily.
Motor overload, insufficient cooling of motor Prevent the motor overloading during cutting,
remove dust from the motor so that ideal cooling
of the motor is ensured.
Reduced cutting
performance during
sawing
Saw blade too small (sharpened too often) Adjust end stop of the saw.
Cut is rough or wavy. Saw blade is blunt, tooth shape is not suited
to material thickness
Sharpen the saw blade or put in suitable saw
blade.
Work piece tears or
splinters.
Cutting pressure too high or saw blade not
suited to application
Put in a suitable saw blade.
Warning! To protect the motor, it is equipped with a thermal switch which turns it off in the event of overloading. After a
short cooling down phase, the motor is turned on again automatically.
