WARNING: Certain dust, such as oak or beech dust, is considered
carcinogenic, especially in connection with wood-treatment additives.
• Always use dust extraction.
• Provide for good ventilation of the work space.
• It is recommended to wear an appropriate respirator.
CAUTION: Never operate this saw for cutting wood unless the
dust bag or D
