blade binding or kicking back.
▶ Secure the workpiece in a sturdy holder. Never hold the workpiece with your hand or across your leg.
▶ Switch the product on only after bringing it to the working position.
▶ When working with the product, always guide it away from your body.
▶ Do not reach underneath the workpiece.
▶ Apply only moderate pressure and cut at an appropriate speed, especially when cutting large-diameter

Hubs stroke.
▶ Never cut into unknown materials and make sure the path of the saw is free of obstructions above and
below the workpiece.
▶ The product can kick back if the saw blade comes into contact with an obstructing object.
▶ Bring your arms into a position in which you can absorb the kickback forces.
▶ The product must be pressed against the workpiece until the contact shoe makes firm contact. This
ensures optimum and safe progress as you work.
▶ Position yourself off to one side of the blade, never bring the blade into line with your body. The saw can
jump backward toward you if kickback occurs!
▶ If the saw blade binds or when you interrupt work for any reason, switch off the saw and hold it motionless
in the material until the saw blade comes to a complete stop. Never attempt to remove the saw from the
workpiece or pull the saw back while the blade is in motion, as otherwise the saw could kick back.
▶ When restarting a saw in the workpiece, center the saw blade in the kerf and check that saw teeth are
not in engagement with the workpiece.
▶ Use extra caution when sawing into walls or other blind areas. As it enters the material the blade might
encounter a hidden obstruction, resulting in kickback.
▶ Engage the transport lock before storing or transporting the product.
▶ Comply with the manufacturer's instructions for handling and storing saw blades.
▶ If work involves break-through, always secure the area on the side opposite where the work is carried
out.
▶ Before beginning work, check the working area for concealed electric cables or gas and water pipes.
External metal parts of the product could give you an electric shock or cause an explosion if you
accidentally damage an electric cable or a gas or water pipe.
