General safety instructions

For your own protection and for the protection of your power tool, pay atten- tion to all parts of the text that are marked with this symbol! 3

WARNING: Reading the operating instruc-tions will reduce the risk of injury.

WARNING: Read all safety warnings and instructions. Failure to follow all safety warn-ings and instructions may result in electric shock, fire and/or serious injury. Keep all safety instructions and information for future reference. Pass on your electrical tool only together with these documents.

Special Safety Instructions

Wear ear protectors with impact drills
(machines with the designation SB). Exposure to noise can cause hearing loss. Hold tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring. If the cutting accessory contacts a “live” wire, exposed metal parts of the electrical tool may become “live” and give the operator an electric shock. 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).

• Protect battery packs from water and mois-ture.
• 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 imme-diately. If the machine is defective, remove the battery pack from the machine. Remove the battery pack from the machine before any adjustments, conversions or servicing are performed. Before fitting the battery pack, make sure that the machine is switched off. Keep hands away from the rotating tool! Remove chips and similar material only with the machine at a standstill. Secure the workpiece to prevent slipping or rotation (e.g. by securing with screw clamps). LED lights (11): Do not observe the LED radiation directly with optical instruments.
Reducing dust exposure:
WARNING – 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.

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).

Use

Battery pack, capacity and signal display Fig. B
Charge the battery pack before use. If performance diminishes, recharge the battery pack. The ideal storage temperature is between 10°C and 30°C. Removing, replacing battery pack Setting direction of rotation, transporting safety device (switch-on lock) Fig. D Selecting gear stage Fig. E Do not set the switch (3) unless the motor has stopped completely!

• Setting torque limitation, drilling, impact drilling Fig. F
• Switching on/off, setting speed Fig. A
• Switching on, speed: press the trigger (12). The speed can be changed by pressing in the trigger.
• Switching off: release the trigger (12).

Note: The noise that the machine makes when it switches off is due to the design (quick stop) and has no influence on the function or the service life of the machine.

Keyless chuck Fig. G
With a soft tool shank, retightening may be required after a short period of operation.
Notes: on machines with the designation SB…: 1. The ratchet sound which can possibly be heard after opening the drill chuck is functional and is switched off by a reverse rotation of the sleeve. Turn sleeve in direction “GRIP, ZU” until the noticeable mechanical resistance has been overcome.
Caution! The chuck is not yet fully tight-ened! Keep turning the sleeve (it must “click” when turning)) until it cannot be turned any further – only now is the tool safely clamped.

Cleaning: From time to time, hold the machine vertically with the keyless chuck facing downwards and turn the sleeve fully in direction “GRIP, ZU” and then turn fully in direction “AUF, RELEASE”. The dust collected falls from the keyless chuck.

Unscrewing chuck Fig. H
Employ the same procedure when attaching the chuck, except in reverse order.

Troubleshooting

The machine’s multifunctional monitoring

machine electronics have activated automatic protection mode. A warning signal sounds (contin-uous beeping). The beeping stops after a maximum of 30 seconds or when the trigger (12) is released. In spite of this protective function, overloading is still possible with certain applications and can result in damage to the machine.
Causes and remedies:

1. Battery pack almost empty Fig. A, B (The electronics protect the battery pack against damage through total discharge). If one LED is flashing (9), the battery pack is almost flat. If necessary, press the (8) button and check the LEDs (9) to see the charge level. If the battery pack is almost flat, it must be recharged.

2. Long continuous overloading of the machine will activate the temperature cut-out. Leave the machine or battery pack to cool. Note: If the battery pack feels very warm, the pack will cool more quickly in an “AIR COOLED” charger.
   Note: The machine will cool more quickly if you operate it at idling speed.

3. Metabo safety shutdown: The machine was SWITCHED OFF automatically. If the slew rate of the current is too high (for example, if the machine suddenly seizes or kickback occurs), the machine switches off. Switch off the machine at the trigger (12). Switch it on again and continue to work as normal. Try to prevent the machine from seizing.

Switch off the machine at the trigger (12). Then continue working as normal. Try to prevent the machine from seizing.
