The circular saw bench is automatically turned off in the event of a
power failure. Press the green button to switch on again.
Switching off
⇒ Press the bottom red button.
The circular saw bench is fitted with a braking motor. The saw blade
must stand still within 10 seconds after it was switched off. The brake
is defective if this time is exceeded. The saw must then be repaired by
the manufacturer or a workshop appointed by the manufacturer.
Never operate the saw with a defective brake!
Motor protection
The motor is fitted with a protective switch which automatically
switches off the motor when it is overloaded. The motor can only be
switched on again after it has cooled down.
Maintenance and Care
Disconnect the mains plug.
Observe the following to maintain the operability of the circular saw
bench:
• Clean and oil all moving parts regularly.
• Always keep the motor's cooling ribs clean to ensure adequate
cooling.
• Ensure that the saw blade is always free of rust and resin.
• Resin residues must be removed from the table board.
• The saw blade (wearing part) becomes blunt after prolonged or
frequent use.
⇒ the blade must be resharpened or replaced.
