▶ Dust produced by grinding, sanding, cutting and drilling can contain dangerous chemicals. Some
examples are: lead or lead-based paints; brick, concrete and other masonry products, natural stone
and other products containing silicates; certain types of wood, such as oak, beech and chemically
treated wood; asbestos or materials that contain asbestos. Determine the exposure of the operator and
bystanders by means of the hazard classification of the materials to be worked. Implement the necessary
measures to restrict exposure to a safe level, for example by the use of a dust collection system or by
the wearing of suitable respiratory protection. The general measures for reducing exposure include:
▶ working in an area that is well ventilated,
▶ avoidance of prolonged contact with dust,
▶ directing dust away from the face and body,
▶ wearing protective clothing and washing exposed areas of the skin with water and soap.
▶ The user and the other persons in the vicinity must wear eye protection, a hard hat, ear protection and
breathing protection while the product is in use.
▶ Risk of injury by falling tools and/or accessories. Before starting work, check that the battery and installed
accessories are secure.
▶ Keep the air vents clear at all times. Risk of burn injuries due to blocked air vents!
▶ Switch the product on only after you have brought it to the working position.
▶ Wait until the product stops completely before you lay it down.
▶ Do not attach a belt hook to this product.
▶ Do not touch the metal head while the product is running because the head is hot.
▶ Do not touch the hot cut area after cutting the material.
▶ The saw blade or other metal parts can be hot or have sharp edges. Wear protective gloves when
changing the saw blade, cleaning the chip collection bag, and cleaning the vents.
▶ Do not hold the workpiece by hand, but use a vise or similar to prevent it from moving during cutting. If
the workpiece moves or vibrates, the operation becomes unstable and cannot be controlled. Stop the
operation immediately and secure the workpiece correctly, otherwise the blade will be damaged and
serious injury can result.
▶ Secure the workpiece to prevent the off-cut from falling and causing injury.
▶ Metal chips and sparks from the cutting operation can damage the surroundings or cause a fire. Hot
metal chips can melt the material of the chip collection bag. Do not operate the product near flammable
or fragile items.
▶ When working at height, it is recommended to install the chip collection bag. Hot chips can fly out and
fall, burning the operators and bystanders.
▶ Do not use a damaged chip collection bag. Fragments of the saw blade or sawdust could fall out of the
chip collection bag and cause injuries.
▶ When working at height, make sure there is no-one below. Off-cuts, material or products dropped could
cause an accident.
▶ Make sure no abnormal sounds or vibrations occur during operation. Operation when abnormal sounds
or vibrations are perceptible can damage the blade, resulting in serious injury.
▶ Metal chips are sharp and can cause injuries. Wear snug-fitting clothing to prevent chips from getting
inside gloves, shoes, or elsewhere.
Kickback - causes and safety instructions
• Kickback is the sudden reaction occurring when the saw blade snags, jams or is out of alignment,
causing uncontrolled movement of the power tool away from the workpiece and toward the operator.
• If the saw blade snags or jams in the kerf, it binds and motor force drives the power tool back toward the
operator.
• If the saw blade twists or is out of alignment in the kerf, the teeth at the trailing edge of the saw blade
can snag in the surface of the workpiece, flicking the saw blade out of the kerf and driving the power tool
back toward the operator.
Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions. It can be
avoided by taking the proper precautions as described below.
▶ Hold the power tool firmly, with your arms into a position where you can absorb the kickback forces.
Always position yourself off to one side of the saw blade; never bring the blade into line with your body.
In the event of a kickback, the power tool can jump backwards, but the operator can control the kickback
forces by taking appropriate precautions.
▶ If the saw blade jams and when you interrupt the operation, switch off the power tool and hold it with
the saw blade in the material until the saw blade has come to a standstill. Never attempt to remove the
power tool from the workpiece or pull it back while the saw blade is in motion, because kickback can
occur. Investigate and take corrective action to eliminate the cause of the blade binding.
