General safety instructions

For your own protection and for the protection of your power tool, pay attention to all parts of the text that are marked with this symbol!

Read the operating instructions to reduce the risk of injury.


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. Always include these documents when passing on your power tool.

Special Safety Instructions

Safety instructions for all operations

1. Wear ear protectors. Exposure to noise can cause hearing loss.
2. Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
3. 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.

Safety instructions when using long drill bits with rotary hammers

1. 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.
2. 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.

Further Safety instructions
Work only with the additional handle correctly installed.
Always hold the machine with both hands using the handles provided, stand securely and concentrate. Wear personal protective equipment and always wear safety glasses. Protective equipment such as dust mask, non-skid safety shoes, protective gloves, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
Ensure that the spot where you wish to work is free of power cables, gas lines or water pipes (e.g. by using a metal detector). Do not touch the rotating tool!
Secure the workpiece against slipping, e.g. with the help of clamping devices.
Remove chips and similar material only when the machine is at a standstill.

when carrying out hard screwdriving (driving of screws with either a metric or an imperial thread into steel)! The head of the screw may be ripped off or high restoring torques may occur on the handle.
High forces are released if the tool jams or catches. Always hold the machine with both hands by the intended handles, take a secure stance and concentrate on the work.
A damaged or cracked additional handle must be replaced. Never operate a machine with a defective additional handle.
LED light (12): do not observe the LED radiation directly with optical instruments.

Do not stare at operating lamp.

Remove the battery pack from the machine before any adjustments, conversions or servicing are performed.
Protect battery packs from water and moisture!
Do not expose battery packs to naked flame!
Do not use faulty or deformed battery packs!
Do not open battery packs!
Do not touch or short-circuit battery packs!
Slightly acidic, flammable fluid may leak from defective li-ion battery packs!
If battery fluid leaks out and comes into contact with your skin, rinse immediately with plenty of water. If battery fluid leaks out and comes into contact with your eyes, wash them with clean water and seek medical attention immediately.
If the machine is defective, remove the battery pack from the machine.

Transport of li-ion battery packs:
The shipping of li-ion battery pack is subject to laws related to the carriage of hazardous goods (UN 3480 and UN 3481). Inform yourself of the currently valid specifications when shipping li-ion battery packs. If necessary, consult your freight forwarder. Certified packaging is available from Metabo.
Only send the battery pack if the housing is intact and no fluid is leaking. Remove the battery pack from the machine for sending. Prevent the contacts from short-circuiting (e.g. by protecting them with adhesive tape).

Reducing dust exposure:

• Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are: - Lead from lead-based paints,
• Crystalline silica from bricks and cement and other masonry products, and
• Arsenic and chromium from chemically treated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.
This also applies to dust from other materials such as some timber types (like oak or beech dust), metals, asbestos. Other known diseases are e.g. allergic reactions, respiratory diseases. Do not let dust enter the body.
Observe the relevant guidelines and national regulations for your material, staff, application and place of application (e.g. occupational health and safety regulations, disposal).
Collect the particles generated at the source, avoid deposits in the surrounding area.
Use suitable accessories for special work. In this way, fewer particles enter the environment in an uncontrolled manner.
Use a suitable extraction unit.

Reduce dust exposure with the following measures:

• do not direct the escaping particles and the exhaust air stream at yourself or nearby persons or on dust deposits,
• use an extraction unit and/or air purifiers,
• ensure good ventilation of the workplace and keep clean using a vacuum cleaner. Sweeping or blowing stirs up dust.
• Vacuum or wash the protective clothing. Do not blow, beat or brush.
