• Do not operate the machine if your full attention is not on the job.

Safety instructions for band saws

Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessories contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

Additional safety instructions

• Keep your hands away from the cutting area and the bandsaw blade. Keep your second hand on the auxiliary handle or the motor housing. When both hands are on the saw they cannot be injured by the saw while it is in use.
• Use the product and accessories only when they are in perfect working order.
• Never tamper with or modify the product or accessories in any way.
•  Do not touch rotating parts – risk of injury!
• Wear eye protection, a hard hat and ear protection while the product is in use.
• Wear protective gloves when changing the accessory tool. Touching the accessory tool can result in cuts and burns.
• 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.
• When ripping always use a fence or straight edge guide. This improves the accuracy of the cut and reduces the chance of the blade binding.
• Do not reach underneath the workpiece. The guard cannot protect you from the saw blade protruding below the workpiece.
• Never hold the workpiece with your hand or other part of the body. Secure the workpiece in a sturdy holder. It is important to secure the workpiece firmly in order to minimize the risk of body contact, blade binding, and loss of control.
• Always hold the product firmly with both hands on the grips provided for the purpose and position your arms to absorb kickback forces.
• Keep the grips dry, clean and free from oil and grease.
• 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!
• Make sure you have a firm stance, especially for overhead work. A sudden break-through can affect your balance.
•  When undertaking break-through work, secure the zone on both sides of the workpiece. Pieces of debris can fall and cause injuries.
•  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.
•  Before starting the cut, check that the bandsaw blade is correctly installed. An incorrectly installed bandsaw blade can bind and cause a kickback.
•  Take frequent breaks and do physical exercises to improve the blood circulation in your fingers. High vibration during long periods of work can lead to disorders of the blood vessels and nervous system in the fingers, hands and wrists.
•  Do not look directly into the light source (LED) of the product and do not aim the beam at other persons’ faces. Risk of dazzling or eye damage.
•  Do not attempt to secure a belt hook in the installation opening for accessories. Use only the belt hook supplied.
•  Risk of injury by falling tools and/or accessories. Before starting work, check that the battery and installed accessories are secure.

Electrical safety

• 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.
• When cutting through pipes, e.g. when carrying out demolition or installation work, check to ensure that the pipes no longer contain liquids and empty them if necessary. When cutting through pipes, hold the product above the level of the pipe you are cutting through. The product is not protected against ingress of moisture.

Careful handling and use of electric tools

• Use only bandsaw blades of the specified size.
• Do not use dull or damaged bandsaw blades. They cause higher friction, binding or kickback of the bandsaw blade.
•  Comply with the manufacturer’s instructions for handling and storing bandsaw blades.

Battery use and care

•  Comply with the following safety instructions for the safe handling and use of Li-ion batteries. Failure to comply can lead to skin irritation, severe corrosive injury, chemical burns, fire and/or explosion.
•  Use only batteries that are in perfect working order.
• Treat batteries with care in order to avoid damage and prevent leakage of fluids that are extremely harmful to health!
•  Do not under any circumstances modify or tamper with batteries!
•  Do not disassemble, crush or incinerate batteries and do not subject them to temperatures over 80 °C (176 °F).
•  Never use or charge a battery that has suffered an impact or been damaged in any other way. Check your batteries regularly for signs of damage.
•  Never use recycled or repaired batteries.
•  Never use the battery or a battery-operated power tool as a striking tool.
• Never expose batteries to the direct rays of the sun, elevated temperature, sparking, or open flame. This can lead to explosions.
• Do not touch the battery poles with your fingers, tools, jewelry, or other electrically conductive objects. This can damage the battery and also cause material damage and personal injury.
• Keep batteries away from rain, moisture and liquids. Penetrating moisture can cause short circuits, electric shock, burns, fire and explosions.
• Use only chargers and power tools approved for the specific battery type. Read and follow the relevant operating instructions.
• Do not use or store the battery in explosive environments.
• If the battery is too hot to touch, it may be defective. Put the battery in a place where it is clearly visible and where there is no risk of fire, at an adequate distance from flammable materials.
