▶
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.
▶
Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless
action can cause severe injury within a fraction of a second.
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.
▶
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 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.
Battery tool use and care
▶
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.
▶
Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
▶
When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small
metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a
fire.
▶
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.
▶
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.
▶
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.
▶
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.
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.
▶
Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service
providers.
