Tip or advice
2 Safety warnings

WARNING! 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.
Save all warnings and instructions for future reference.
Observe the operating manual of the power tool.
- Do not manipulate or block controls, e.g. the on/off switch.
- Wear suitable personal protective equipment: Ear protection, safety goggles, a dust mask for work that generates dust.
- Do not wear loose-fitting clothing or jewellery. If you have long hair, wear a hairnet or tie your hair up. Keep hair and clothing away from moving parts.
Loose-fitting clothing, jewellery or long hair can be caught by moving parts. - Do not use any insertion tools or accessories that the manufacturer has not specially designed or recommended for
the mobile hole drilling attachment. Just because you can attach accessories or insertion tools to your mobile hole drilling attachment does not guarantee that they can be used safely. This may increase the risk of injury, accelerate the wear on the mobile hole drilling attachment 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.
- Do not use or store the mobile hole drilling attachment in the rain or in damp surroundings.
- Place the mobile hole drilling attachment on a solid and even surface. If the mobile hole drilling attachment slides or tilts, it may not be possible to control the power tool safely and reliably.
- This device must not be used by persons (including children) with reduced physical, sensory or mental capabilities or lack of experience and knowledge. Children must be supervised to ensure that they do not play with the device.
2.1 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.
