This will ensure that the safety of the power tool is maintained.
2.2

Safety instructions for reciprocating saws

▶ Hold the power tool by insulated gripping surfaces, when performing an operation where the
cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a "live"
wire may make exposed metal parts of the power tool "live" and could give the operator an electric
shock.
▶ Use clamps or another practical way to secure and support the workpiece to a stable platform.
Holding the workpiece by hand or against your body leaves it unstable and may lead to loss of control.

Additional safety instructions for saws

Personal safety
▶ Keep your hands away from the cutting area and the 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 it.
▶ Use the product only when it is in perfect working order.
▶ Never tamper with or modify the power tool in any way.
▶ Do not touch rotating parts – risk of injury!
▶ Wear protective gloves also when changing the accessory tool. Touching the accessory tool presents a
risk of injury (cuts or burns).
▶ Before starting work, check the hazard class of the dust that will be produced when working. Use
an industrial vacuum cleaner with an officially approved protection class in compliance with the locally
applicable dust protection regulations. Dust from materials such as lead-based paint, certain types of
wood and concrete/masonry/stone containing quartz, minerals or metal can be harmful to health.
▶ Make sure that the workplace is well ventilated and, if necessary, wear a respirator appropriate for
the type of dust generated. Contact with or inhalation of the dust can cause allergic reactions and/or
respiratory or other diseases among operators or bystanders. Only specialists are permitted to handle
material containing asbestos.
▶ Do not reach underneath the workpiece.
▶ 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 clean and dry.
▶ 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.
Electrical safety
▶ Before beginning work, check the working area for concealed electric cables or gas and water pipes.
External metal parts of the power tool can become live, presenting a risk of electric shock, if you
accidentally damage an electric cable.
▶ Hold the power tool by the insulated gripping surfaces when performing work in which the accessory
tool might come into contact with concealed wiring. If the accessory tool comes into contact with a live
wire, metal parts of the power tool can also become live, resulting in an electric shock.
2.4

Additional safety instructions

▶ Use the product only when it is in perfect working order.
▶ Never tamper with or modify the product in any way.
▶ Do not use dull or damaged blades. These cause increased friction and present a high risk of the saw
blade binding or kicking back.
▶ 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 if you accidentally damage an electric
cable.
