Tip or advice
2 Safety warnings
2.1 General power tool safety warnings

WARNING! Read all safety warnings, instructions, 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.
Follow the operating manual for the charger and the battery pack.
2.2 Machine-specific safety notices
- Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting accessory or fasteners may contact hidden wiring. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.
- Use appropriate detection devices to look for any hidden supply lines or consult your local utility company. If the insertion tool makes contact with live cables, it can result in fire and electric shock. Damage to a gas pipe can lead to an explosion. Penetration of a water pipe can result in damage to property.
- Keep the power tool away from magnetic fields. The power tool may switch on unexpectedly and cause injury.
- Wear suitable personal protective equipment: Ear protection, safety goggles, a dust mask for work that generates dust.

CAUTION! Power tool can jam and cause sudden kickback! Switch off immediately!
- Firmly hold the power tool with one hand on the handle [1-10] and keep the other hand away from the hazard area. Make sure the speed is adjusted correctly when screwdriving. Be prepared for a high reaction torque, which may cause the power tool to turn and lead to injury.
- Do not use the power tool in the rain or in damp surroundings. Moisture in the power tool may cause a short circuit and fire.
- 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 manipulate or block controls, e.g. the on/off switch.
-
Do not use power supply units to operate cordless power tools. Only use the intended battery packs. Do not use third-party chargers to charge the battery packs. The use of accessories not expressly authorised by the manufacturer can result in electric shocks and/or serious accidents.
- Do not use any insertion tools or accessories that the manufacturer has not specially designed or recommended for this power tool. Just because you can attach accessories or insertion tools to your power tool does not guarantee that they can be used safely. This may increase the risk of injury, accelerate the wear on the power tool and decrease the quality of the working results.
Depending on the type and use of the accessory, particles, the insertion tool or parts of the insertion tool could come loose. This can lead to increased exposure to dust and to unexpected movements.
Wear suitable personal protective equipment. Be prepared for a high reaction torque, which may cause the power tool to turn and lead to injury.
2.3 Safety instructions when using long drill bits
- Never operate at higher speed than the maximum speed rating of the drill bit. At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.
- Always start drilling at low speed and with the bit tip in contact with the workpiece. At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.
- Apply pressure only in direct line with the bit and do not apply excessive pressure. Bits can bend causing breakage or loss of control, resulting in personal injury.
2.4 Emission levels
The levels determined in accordance with EN 62841 are typically:
Drilling
Sound pressure level L PA=68 dB(A)
Sound power level L WA=76dB(A)
Uncertainty K = 5 dB
Fastening
Sound pressure level L PA=67 dB(A)
Sound power level L WA=75dB(A)
Uncertainty K = 3 dB

CAUTION
Noise emissions created while working with the power tool may damage your hearing.
Always use ear protection.
Vibration emission level a_h (vector sum for three directions) and uncertainty K measured in accordance with EN 62841:
Drilling in metal a_h = 3.6 m/s^2
$$ K = 1. 5 \mathrm {m} / \mathrm {s} ^ {2} $$
Fastening a_h < 2.5m / s^2
$$ K = 1. 5 \mathrm {m} / \mathrm {s} ^ {2} $$
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.
Assess the actual load during the entire operating cycle.
- Depending on the actual load, suitable protective measures must be defined in order to protect the operator.
3 Intended use
Cordless drill suitable
- for drilling in metal, wood, plastics and similar materials,
- for screwing in and tightening screws.
- intended for use with BP Festool battery packs of the same voltage class.
The user is liable for damage and accidents caused by improper and non-intended use; this also includes damage and wear caused by continuous industrial operation.
