Hilti SC 4WL-22 Manual De Instrucciones Original página 12

▶ Remove the battery if a problem occurs with the power tool, whenever you change accessory tools or
accessories and before storing or transporting the power tool.
▶ Do not work overhead with the power tool.
▶ Do not attempt to brake the power tool by applying lateral pressure to the saw blade.
▶ Before inserting the battery, check that the saw is switched off and that the switch-on interlock is
activated. In this way you avoid injuries due to unintentional starting of the power tool.
▶ While the power tool is running, do not touch the clamping flange or the clamping screw.
▶ Before you lay down the power tool, wait until the power tool has come to a complete stop.
▶ Before changing the accessory tool, wait until the power tool has cooled down.
▶ Never press the drive spindle lock button while the saw blade is rotating.
▶ Never direct the power tool toward persons.
▶ The switch-on interlock must always be activated whenever you change accessories or the battery, for
transport and when you are going to stow the power tool away.
▶ Always use a saw blade suitable for the material and the condition of the workpiece.
▶ Adapt forward pressure to the saw blade and the material being cut. In this way you prevent the saw
blade from stalling and possibly causing kickback.
▶ Make sure that the path of the saw is free of obstructions such as nails, screws and other metal objects.
▶ Avoid overheating the tips of the saw blade teeth.
▶ When cutting plastic, make sure that the workpiece does not become too hot and melt.
▶ The rated speed of the accessory tool must be at least equal to the maximum speed marked on the
power tool. Accessories running faster than their rated speed can disintegrate and fly apart.
▶ Do not work in an environment heavily contaminated with dust.
▶ 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.
▶ Always wear a dust mask that meets the requirements of the application.
▶ 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 classification in compliance with locally
applicable dust protection regulations.
▶ Comply with national health and safety requirements.
▶ Use clamps or some other practical means to secure the workpiece and keep it in a stable position.
Attempting to stabilize the workpiece by hand or with your body is inadequate and can result in loss of
control. Do not have the workpiece held in position by a helper.
▶ Do not look directly into the light source (LEDs) incorporated in the power tool and do not direct the light
at other persons' faces.
▶ Risk of injury by falling tools and/or accessories. Before starting work, check that installed accessories
are secure.
▶ Bring the saw blade into contact with the workpiece only when the circular saw is switched on.
▶ Use only saw blades recommended by Hilti that comply with the EN 847-1 standard.
Electrical safety
▶ Before beginning work, check the working area (e.g. using a detector) to ensure that no concealed
electric cables or gas and water pipes are present. External metal parts of the power tool can become
live, for example if you accidentally damage electric wiring. This causes an increased risk of electric
shock.
2.4 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.
