regularly freed of chips and dust to ensure
correct cooling.
• If the motor suddenly stops while sawing,
let go of the switch immediately. Loosen the
saw blade from the piece of work, after which
sawing can continue.
• Using long cables of too small a diameter
can result in loss of voltage, which can lead to
problems with the motor.
• For a length up to 15 metres a cable must
be used with a diameter of 1.5 mm2.
• For a length of between 15 and 40 metres
a cable must be used with a diameter of 2.5
mm2.
Turn the appliance off immediately in the
event of:
• A faulty mains plug, mains flex or flex
damage.
• A faulty switch.
• Smoke or smell from scorched insulation.
• Seizing of the saw.
