General Power Tool Safety Warnings

22.1 Introduction
This chapter reproduces the pre-formulated, general safety precautions specified in the IEC 62841 standard for handheld motor-operated electric tools.
STIHL is obliged to publish these texts.
The safety precautions and warnings on avoiding an electric shock given under “Electrical Safety” do not apply to STIHL cordless products.

WARNING
Read all the safety precautions, instructions, illustrations and specifications accompanying this electric power tool.
Failure to follow the safety warnings and instructions may result in electric shock, fire and/or serious injury. Save all safety warnings and instructions for future reference.
The term “electric power tool” in the safety warnings refers to mains-operated (corded) power tools or battery-operated (cordless) power tools.

22.2 Work area safety
a)Keep work area clean and well lit. Cluttered or 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.

22.3 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, hanging up, 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 suitable for outdoor use. Use of a cord extension suitable for outdoor use reduces the risk of electric shock.
f) 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.

22.4 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 personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, nonskid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
c) 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 power tool.
Carrying power tools with your finger on the switch or energizing 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 jewelery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelery or long hair can be caught in moving parts.
g) If dust extraction and collection devices can be mounted, they should be connected and used correctly. Use of dust collection can reduce dust-related hazards.
h)Do not be lulled into a false sense of security and do not disregard the safety rules even if you are thoroughly familiar with the electric power tool. Carelessness can result in serious injuries within fractions of a second.

22.5 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 and/or take a removable battery pack out of 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.
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 and accessories with care. 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 attachments sharp and clean. Properly maintained cutting attachments with sharp cutting edges are less likely to bind and are easier to control.
g)Use the power tool, accessories, 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.
h)Keep handles and grip surfaces dry, clean and free from oil and grease. Slippery handles and grip surfaces doe not allow proper operation and control of the power tool in unforeseen situations.

22.6 Battery tool use and care
a)Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
b)Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
c) When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small objects that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
d)Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
e)Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.
f) Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 130 °C (265 °F) may cause explosion.
g)Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

22.7 Service
a)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.
b)Never service damaged batteries. Service of battery packs should only be performed by the manufacturer or authorized service providers.

22.8 Hedge Trimmer Safety Warnings
– Keep all parts of the body away from the cutting blades.
Do not remove cut material or hold material to be cut when blades are moving. Make sure the switch is off when clearing jammed material. A moment of inattention while operating the hedge trimmer may result in serious personal injury.
– Carry the hedge trimmer by the handle with the cutting blades stopped. When transporting or storing the hedge trimmer always fit the blade scabbard. Proper handling of the hedge trimmer will reduce possible personal injury from the cutting blades.
– Always hold your electric power tool by the insulated handles because the cutting blades may contact hidden electrical wires. Any blade contact with a live wire may energize metallic parts of the power tool and result in an electric shock.
