Hilti ST 1800 Manual De Instrucciones página 18

▶ Disconnect the plug from the power source and/or remove the battery pack, if detachable, from
the power tool before making any adjustments, changing accessories, or storing power tools.
Such preventive safety measures reduce the risk of starting the power tool accidentally.
▶ Store idle power tools out of the reach of children and do not allow persons unfamiliar with the
power tool or these instructions to operate the power tool. Power tools are dangerous in the hands
of untrained users.
▶ Maintain power tools and accessories. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may affect the power tool's operation. If damaged,
have the power tool repaired before use. Many accidents are caused by poorly maintained power
tools.
▶ Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
▶ Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking
into account the working conditions and the work to be performed. Use of the power tool for
operations different from those intended could result in a hazardous situation.
▶ Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.
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.
2.2 Safety warnings for screwdrivers and impact wrenches
▶ Hold the power tool by insulated gripping surfaces, when performing an operation where the
fastener may contact hidden wiring or its own cord. Fasteners contacting a "live" wire may make
exposed metal parts of the power tool "live" and could give the operator an electric shock.
2.3 Additional safety precautions for screwdrivers
Personal safety
▶ 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.
▶ Use auxiliary handles supplied with the product. Loss of control can cause personal injury.
▶ Always hold the product with both hands on the grips provided. Keep the grips clean and dry.
▶ Do not touch rotating parts – risk of injury!
▶ Wear suitable eye protection, a hard hat, ear protection, and light 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.
