▶
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.

▶
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

Read all safety warnings, instructions, illustrations and specifications provided with this power
tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.

Operations such as polishing are not to be performed with this power tool. Operations for which the
power tool was not designed may create a hazard and cause personal injury.
▶
Do not convert this power tool to operate in a way which is not specifically designed and specified
by the tool manufacturer. Such a conversion may result in a loss of control and cause serious personal
injury.

Do not use accessories which are not specifically designed and specified by the tool manufacturer.
Just because the accessory can be attached to your power tool, it does not assure safe operation.
▶
The rated speed of the accessory must be at least equal to the maximum speed marked on the

Do not use a damaged accessory. Before each use inspect the accessory such as abrasive
wheels for chips and cracks, backing pad for cracks, tear or excess wear, wire brush for loose or
cracked wires. If power tool or accessory is dropped, inspect for damage or install an undamaged
accessory. After inspecting and installing an accessory, position yourself and bystanders away
