▶
Do not look directly into the light source (LED) of the product and do not aim the beam at other
persons’ faces. Risk of dazzling or eye damage.
▶
Always engage the switch-on interlock before storing or transporting the saw. This prevents unintentional
starting of the product.
▶
Risk of injury by falling tools and/or accessories. Before starting work, check that installed accessories
are secure.
Electrical safety
▶
Before beginning work, check the working area (e.g. using a metal detector) to ensure that no
concealed electric cables or gas and water pipes are present. External metal parts of the power
tool may become live, for example, when an electric cable is damaged accidentally. This constitutes a
serious risk of electric shock.
Using and handling the power tool
▶
To avoid damage to the product, use the scaffold hook to hang up the product at a secure location
only. Maximum height for storage: 50 cm/20 in. Make sure that the product is securely engaged on the
scaffold hook.
▶
Bring the saw blade into contact with the workpiece only when the circular saw is switched on.
▶
The path of the saw must be free of obstructions above and below the workpiece. Do not saw into
screws, nails or similar objects.
▶
Always use a saw blade that is suitable for the material you are going to saw.
▶
Use only saw blades recommended by Hilti that comply with the EN 847-1 standard.

Failure to comply can lead to skin irritation, severe corrosive injury, chemical burns, fire and/or explosion.
▶
Use only batteries that are in perfect working order.
▶
Treat batteries with care in order to avoid damage and prevent leakage of fluids that are extremely
harmful to health!
▶
Do not under any circumstances modify or tamper with batteries!
▶
Do not disassemble, crush or incinerate batteries and do not subject them to temperatures over 80 °C
(176 °F).
▶
Never use or charge a battery that has suffered an impact or been damaged in any other way. Check
your batteries regularly for signs of damage.
▶
Never use recycled or repaired batteries.
▶
Never use the battery or a battery-operated power tool as a striking tool.
▶
Never expose batteries to the direct rays of the sun, elevated temperature, sparking, or open flame. This
can lead to explosions.
▶
Do not touch the battery poles with your fingers, tools, jewelry, or other electrically conductive objects.
This can damage the battery and also cause material damage and personal injury.
▶
Keep batteries away from rain, moisture and liquids. Penetrating moisture can cause short circuits,
electric shock, burns, fire and explosions.
▶
Use only chargers and power tools approved for the specific battery type. Read and follow the relevant
operating instructions.
▶
Do not use or store the battery in explosive environments.
▶
If the battery is too hot to touch, it may be defective. Put the battery in a place where it is clearly visible
and where there is no risk of fire, at an adequate distance from flammable materials. Allow the battery to
cool down. If it is still too hot to touch after an hour, the battery is faulty. Consult Hilti Service or read the
