▶
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.
2.2 Safety instructions for all saws
Cutting procedures
▶
DANGER: Keep hands away from cutting area and the blade. Keep your second hand on
auxiliary handle, or motor housing. If both hands are holding the saw, they cannot be cut by the blade.
▶
Do not reach underneath the workpiece. The guard cannot protect you from the blade below the
workpiece.
▶
Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth of the blade teeth
should be visible below the workpiece.
▶
Never hold the workpiece in your hands or across your leg while cutting. Secure the workpiece
to a stable platform. It is important to support the work properly to minimise body exposure, blade
binding, or loss of control.
▶
Hold the power tool by insulated gripping surfaces, when performing an operation where the
cutting tool may contact hidden wiring. Contact with a "live" wire will also make exposed metal parts
of the power tool "live" and could give the operator an electric shock.
▶
When ripping, always use a rip fence or straight edge guide. This improves the accuracy of cut and
reduces the chance of blade binding.
▶
Always use blades with correct size and shape (diamond versus round) of arbour holes. Blades
that do not match the mounting hardware of the saw will run off-centre, causing loss of control.
▶
Never use damaged or incorrect blade washers or bolt. The blade washers and bolt were specially
designed for your saw, for optimum performance and safety of operation.
