▶ When battery pack is not in use, keep it away from other metal objects, like paper clips, coins,
keys, nails, screws or other small metal objects, that can make a connection from one terminal to
another. Shorting the battery terminals together may cause burns or a fire.
▶ Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact
accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid
ejected from the battery may cause irritation or burns.
▶ Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may
exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.
▶ Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature
above 130° C (265 °F) may cause explosion.
▶ Follow all charging instructions and do not charge the battery pack or tool outside the temperature
range specified in the instructions. Charging improperly or at temperatures outside the specified range
may damage the battery and increase the risk of fire.
Service
▶ Have your power tool serviced by a qualified repair person using only identical replacement parts.
This will ensure that the safety of the power tool is maintained.
▶ Never service damaged battery packs. Service of battery packs should only be performed by the
manufacturer or authorized service providers.
2.2 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 grip
or the motor housing. If both hands are holding the saw, they cannot be injured by the saw.
▶ Only use the product if it is in perfect working order.
▶ Never tamper with or modify the tool in any way.
▶ Avoid touching 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 may be harmful to health.
▶ Make sure that the workplace is well ventilated and, where necessary, wear a respirator appropriate for
the type of dust generated. Contact with or inhalation of the dust may cause allergic reactions and/or
respiratory or other diseases to the operator or bystanders. Material containing asbestos may be handled
only by specialists.
▶ Blade depth and bevel adjusting locking levers must be tight and secure before making cut. If the blade
adjustment mechanism shifts while cutting, it may cause the saw blade to bind and kick back.
▶ Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth of the blade should be
visible below the workpiece.
▶ 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 below the workpiece.
▶ Never hold the piece being cut in your hands or across your leg. Secure the workpiece to a stable
support.
▶ Always hold the tool with both hands on the grips provided and bring your arms into a position in which
they can take up the force of any kickback.
▶ Keep the grips clean and dry.
▶ Position your body to either side of the blade, but not in line with the blade. The saw may jump back if
kickback occurs.
▶ If the saw blade binds or sticks, or if the cutting operation has to be interrupted, switch the saw off and
hold the saw steady until the saw blade comes to a complete standstill. Never attempt to remove the
saw from the workpiece or pull the saw back while the blade is in motion. Kickback may otherwise occur.
▶ When restarting the saw in the workpiece, center the saw blade in the kerf and check that saw teeth are
not engaged in the material to be cut.
▶ Use extra caution when cutting into existing walls or other blind areas. The protruding blade may cut into
concealed objects, causing stalling and kickback.
