2.1 General power tool safety warnings

WARNING! Read all safety warnings, in structions, illustrations and specifica tions provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference. The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool. Follow the operating manual for the charger and the battery pack.

2.2 Machine-related safety instructions

– Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring. Autting accessory contact ing a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock. – Use clamps or another practical way to se cure and support the workpiece to a stable platform. Holding the workpiece by hand or against your body leaves it unstable and may lead to loss of control. – Wait until the power tool has come to a complete halt before placing it down. The insertion tool can get caught and lead to a loss of control of the power tool. – Do not use deformed or cracked saw blades or cutting sets or saw blades with blunt or broken cutting edges. – The saw blade on the power tool must al ways be running when it makes contact with the workpiece.

Wear suitable personal protective equip ment: ear protection, safety goggles, a dust mask for work which generates dust, and protective gloves when working with raw materials and when changing tools. – Hazardous/toxic dust may be produced during work (e.g. wood dust or mineral wool dust). Contact with or inhalation of this dust may pose a risk for the operating personnel or persons in the vicinity. Com ply with the safety regulations that apply in your country. English 15Wear a P2 respiratory mask to pro tect your health. – Always connect the machine to a dust ex tractor when performing work that gener ates dust. – Do not use power supply units or third- party battery packs to operate cordless power tools. Do not use third-party charg ers to charge the battery packs. The use of accessories not expressly authorised by the manufacturer can result in electric shocks and/or serious accidents.

The levels determined in accordance with EN 62841 are typically: Sound pressure level L

= 86 dB(A) Sound power level L

= 97 dB(A) Uncertainty K = 5 dB CAUTION Noise generated when working Risk of damage to hearing ► Use ear protection. Vibration emission level a

(vector sum for three directions) and uncertainty K measured in accordance with EN 62841: Flexible mineral wool 240 mm 350 mm Main handle

The specified emission levels (vibration, noise) – are used to compare machines. – They are also used for making preliminary estimates regarding vibration and noise load during operation. – They represent the primary applications of the power tool. CAUTION The emission values may deviate from the specified values. This is dependent on how the tool is used and the type of workpiece being machined. ► The actual load during the entire operating cycle must be evaluated. ► Depending on the actual load, suitable pro tective measures must be defined in order to protect the operator. 3 Intended use The cordless insulating-material saw is de signed to saw flexible insulating materials made of mineral wool (glass or stone wool) or natural fibres (e.g. wood or hemp fibres) as well as to saw insulating materials made of PUR/PIR (polyurethane hard foam), polystyrene or pres sure-resistant mineral wool. In accordance with the intended use, only insu lating materials with the following raw densi ties may be machined: Flexible natural fibres < 90 kg/m³ Flexible mineral wool < 100 kg/m³ Pressure-resistant mineral wool 100–170 kg/m³ PUR/PIR < 36 kg/m³ Polystyrene < 45 kg/m³ The cordless insulating-material saw is not suitable for sawing chipboard, metal, wood or pressure-resistant insulating materials made of natural fibres. This power tool may only be used by experts or instructed persons. Only saw insulating materials with the cutting set intended for this purpose, see section 6.2. The user is liable for damage and acci dents caused by improper and non-inten ded use. – intended for use with BP Festool battery packs of the same voltage class.

6.1 Switching on/off

The power tool features an on/off switch on both sides. Use either switch to switch the pow er tool on or off. Switching on ► Press the on/off switch [1-5] twice in quick succession. Switching off ► Press the on/off switch [1-5] once.

6.2 Selecting a cutting set

Only use cutting sets that have been ap proved by the manufacturer. Two cutting sets, each available in two lengths, are available for machining. Cutting set with serrated saw blade (available as an accessory depending on the model) The cutting set with serrated saw blade (SG-240/W-ISC, SG-350/W-ISC) consists of a guide rail with both a movable and a fixed saw blade. The cutting set with serrated saw blade must be adjusted before initial operation, see section 8.3. To ensure an optimum tool life for the ser rated saw blade, use a separate cutting set for mineral wool and a separate cutting set for natural fibres. The saw blade is no longer suitable for sawing natural fibres once it has been used to saw mineral wool. Cutting set with cross-set saw blade (accessory) The cutting set with cross-set saw blade (SG-240/G-ISC, SG-350/G-ISC) consists of a guide rail and a movable saw blade.
