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.

sharp-edged burrs. Use the waste container whenever possible.
▶ Threaded rods cut to length and also the offcuts can be hot and sharp-edged. Wear protective gloves
when you have to touch the threaded rod or the offcut.
▶ The securing screws of the cutting edges can work loose over a lengthy period of operation. Before each
use, check that the securing screws are correctly tightened; tighten the securing screws if necessary.
▶ Stop working as soon as the housing of the power tool gets hot. Allow the power tool to cool down
and then resume working. Do not work continuously without breaks over several consecutive battery
changes or battery charges.
▶ Before each use, check that the cutting edges are securely installed on the tool body.
