Safety rules

General safety rules

• WARNING- Read all instructions! Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. The term “power tool” in all of the warnings listed below refers to your mains operated (corded) power tool or battery operated (cordless) power tool.

SAVE THESE INSTRUCTIONS

Work area

a) Keep the work area clean and well lit. Cluttered and dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical safety

a) 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.
b) 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.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
d) 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.
e) When operating a power tool outdoors, use an extension cord approved for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

Personal safety

a) 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.
b) Use safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
c) Avoid accidental starting. Ensure the switch is in the off position before plugging in. Carrying power tools with your finger on the switch or plugging in power tools that have the switch on invites accidents.
d) 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.
e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
f) 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.
g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of these devices can reduce dust related hazards.

Power tool use and care

a) 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.
b) 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.
c) Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
d) 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.
e) 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.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc., in accordance with these instructions and in the manner intended for the particular type of power tool, 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

a) Have your power tool serviced by a qualified repair person using only genuine replacement parts. This will ensure that the safety of the power tool is maintained.

Additional safety precautions

Personal safety

a) Wear ear protectors with impact drills. Exposure to noise can cause hearing loss.
b) Use the auxiliary handle supplied with the tool.
Loss of control of the tool may lead to injury.
c) Always hold the tool securely with both hands on the grips provided. Keep the grips clean, dry and free from oil and grease.
d) Adjust the side handle to the desired position and check that it is fitted and secured correctly. Hold the side handle tightly at its farthest end.
e) Avoid contact with rotating parts. Switch the tool on only once it has been brought into the working position close to the workpiece.
f) Operate the tool only as directed and only when it is in faultless condition.
g) Wear protective gloves when changing insert tools.
The insert tool may become hot during use. h)Breathing protection must be worn when the tool is used without a dust removal system for work that creates dust.
i) To avoid tripping and falling when working, always lead the sypply cord, extension cord and dust extraction hose away tho the rear.
j) Do not use damaged insert tools.
k) Exercise your fingers during pauses between work to improve the blood circulation in your fingers.

Power tool use and care

a) Secure the work piece. Use clamps or a vice to hold the work piece in place. The workpiece is thus held more securely than by hand and both hands remain free to operate the tool.
b) Ensure that the insert tools used are equipped with the appropriate connection end system and that they are properly fitted and secured in the chuck.
c) In the event of a power faillure, switch the tool off and unplug the supply cord. This prevents inadvertent starting when the power returns.

Electrical safety

a) Before beginning work, check the working area (e.g. with a metal detector) to ensure that no concealed electric cables or gas and water pipes are present. External metal parts of the tool may become live if, for example, an electric cable is damaged inadvertently. This presents a serious risk of electric shock.
b) Check the condition of the supply cord and its plug connections and have it replaced by a qualified electrician if damage is found. Check the condition of the extension cord and replace it if damage is found.
Do not touch the supply in the event of it suffering damage while working. Disconnect the supply cord plug from the socket. Damaged supply cords and extension cords present a risk of electric shock.
c) Dirty or dusty electric tools should thus be checked at a Hilt service center at regular intervals, especially if used frequently for working on conductive materials. Dust (especially dust from conductive materials) or dampness adhering to the surface of the tool may, under unfavorable conditions, present a risk of electric shock.

Work area

a) Ensure that the workplace is well lit.
b) Ensure that the workplace is well ventilated. Poorly ventilated workplaces may be injurious to the health due to exposeure to dust.

Personal protective equipment

The user and any other persons in the vicinity must wear suitable eye protection, a hard hat, ear protection and protective gloves when the tool is in use. Breathing protection must be worn if no dust removal system is used.

• Wear eye protection
