2 Safety

2.1 General power tool safety warnings

WARNING

Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated

(cordless) power tool.

Work area safety

▶

Keep work area clean and well lit. Cluttered or dark areas invite accidents.

▶

Do not operate power tools in explosive atmospheres, such as in the presence of flammable

liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

▶

Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical safety

▶

Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter

plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.

▶

Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and

refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

▶ Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

▶

Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep

cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.

▶ When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

▶

If operating a power tool in a damp location is unavoidable, use a residual current device (RCD)

protected supply. Use of an RCD reduces the risk of electric shock.

Personal safety

▶

Stay alert, watch what you are doing and use common sense when operating a power tool. Do

not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.

▶ Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

▶

Prevent unintentional starting. Ensure the switch is in the off‐position before connecting to power

source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.

▶

Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.

▶ Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

▶

Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away

from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.

▶

If devices are provided for the connection of dust extraction and collection facilities, ensure these

are connected and properly used. Use of dust collection can reduce dust-related hazards.

Power tool use and care

▶

Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.

Printed: 24.01.2017 | Doc-Nr: PUB / 5165611 / 000 / 04

▶

Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.

▶

Disconnect the plug from the power source and/or the battery pack 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. 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.

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 Hammer safety warnings

▶ Wear ear protectors. Exposure to noise can cause hearing loss.

▶ Use auxiliary handles, if supplied with the tool. Loss of control can cause personal injury.

▶

Hold 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.

2.3 Additional safety instructions

Personal safety

▶ Use the product only when it is in technically faultless condition.

▶

Never tamper with or modify the tool in any way.

▶

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.

▶

Check that the side handle is fitted correctly and tightened securely. Always hold the tool securely with both hands on the grips provided. Keep the grips dry, clean and free from oil and grease.

▶ Take breaks between working and do physical exercises to improve the blood circulation in your fingers.

Exposure to vibration during long periods of work can lead to disorders of the blood vessels and nervous system in the fingers, hands and wrists.

▶

The tool is not intended for use by debilitated persons who have received no special training.

▶

Keep the power tool out of reach of children.

▶ Before beginning the work, check the hazard classification of the dust that will be produced. Use an industrial vacuum cleaner with an officially approved protection classification in compliance with locally applicable dust protection regulations.

▶ Use a dust removal system and suitable vacuum cleaner whenever possible. Dust from materials, such as paint containing lead, some wood species, concrete/masonry/stone containing silica, and minerals as well as metal, may be harmful.

▶

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. Certain kinds of dust are classified as carcinogenic such as oak and beech dust, especially in conjunction with additives for wood conditioning

(chromate, wood preservative). Material containing asbestos may be handled only by specialists.

▶ Approval must be obtained from the site engineer or architect prior to beginning the work. Work on buildings and other structures may influence the statics of the structure, especially when steel reinforcing bars or load-bearing components are cut through.

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 may give you an electric shock if you damage an electric cable accidentally.
