▶
Use auxiliary grips supplied with the product. Loss of control can cause personal injury.
▶
Apply appropriate safety measures at the opposite side of the workpiece in work that involves breaking
through. Parts breaking away could fall out and / or fall down causing injury to other persons.
▶
Always hold the tool with both hands on the grips provided. Keep the grips clean and dry.
▶
Hold the product 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.
▶
Do not touch rotating parts – risk of injury!
▶
Wear eye protection, a hard hat and ear protection and suitable respiratory 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.
▶
Wear eye protection. Flying fragments can injure the body and eyes.
▶
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.
▶
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.
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.
Power tool use and care
▶
Switch the product off immediately if the accessory tool jams. The product might twist off-line.
▶
Wait until the product has come to a complete stop before you lay it down.
2.3 Careful handling and use of batteries
▶
Observe the special guidelines applicable to the transport, storage and use of lithium-ion batteries.
▶
Do not expose batteries to high temperatures, direct sunlight or fire.
▶
Do not disassemble, crush or incinerate batteries and do not subject them to temperatures over 80 °C
(176 °F).
▶
Do not use or charge batteries that have suffered mechanical impact, have been dropped from a height
or show signs of damage. In this case, always contact your Hilti Service .
▶
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. Allow the battery to
cool down. If it is still too hot to touch after an hour, the battery is faulty. Contact Hilti Service .
