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!

WARNING

• Reading the operating instructions will reduce the risk of injury.
• Read all safety warnings and instructions. Failure to follow all safety warnings and instructions may result in electric shock, fire and/or serious injury.

Keep all safety instructions and information for future reference.
Pass on your power tool only together with these documents.

Special Safety Instructions
Wear ear protectors. Exposure to noise can cause hearing loss.
Use the auxiliary handle(s), supplied with the tool. Loss of control can cause personal injury.
Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory 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.
Always hold the machine with both hands at the intended handles, take a secure stance and concentrate on the work.
Always wear protective goggles, gloves, and sturdy shoes when working with this tool.
Ensure that the spot where you wish to work is free of power cables, gas lines or water pipes (e.g. using a metal detector).

Secure the workpiece against slipping or turning, e.g. with the help of clamping devices.
Keep hands away from the rotating tool! Remove chips and similar material only with the machine at a standstill.
Caution must be exercised when driving screws into hard materials (driving screws with metric or imperial threads into steel)! The screw head may break or a high reverse torque may build up on the handle.

Metabo S-automatic safety clutch.
When the safety clutch responds, switch off the machine immediately! If the tool jams or catches, the power supply to the motor is restricted. Due to the strong force which can arise, always hold the machine with both hands using the handles provided, stand securely and concentrate.
A damaged or cracked additional handle must be replaced. Never operate a machine with a defective additional handle.
Before fitting the battery pack, make sure that the machine is switched off.
Remove the battery pack from the machine before making any adjustments, changing tools, maintaining or cleaning.

Protect battery packs from water and moisture!

• Do not expose battery packs to fire!
• Do not use faulty or deformed battery packs!
• Do not open battery packs!
• Do not touch contacts or short-circuit battery packs!

A 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!
LED lights (15): Do not observe the LED radiation directly with optical instruments.

Reduce dust exposure:
Some dust created by using this power tool may contain chemicals known to cause cancer, allergic reaction, respiratory disease, 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, arsenic and chromium from chemically-treated lumber, hard wood like oak or beech, metals, asbestos.
The risk from these exposures depends on how long you or bystanders are being exposed.

Do not let particles enter the body.
To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
Observe the relevant guidelines for your material, staff, application and place of application (e.g. occupational health and safety regulations, disposal).
Collect the generated particles at the source, avoid deposits in the surrounding area.
Use suitable accessories for special work (see chapter 9.), thus less 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

Commissioning

Assembly of the additional handle

For safety reasons, always use the additional handle supplied.

Open the clamping ring by turning the additional handle (1) counter-clockwise. Push the additional handle onto the collar of the machine. Insert the depth stop (4). Securely tighten the additional handle at the angle required for the application.

Battery pack
Charge the battery pack (14) before use.
If performance diminishes, recharge the battery pack.

The ideal storage temperature is between 10°C and 30°C.
Li-Ion battery packs “Li-Power” have a capacity and signal indicator (13):

• Press the button (12), the LEDs indicate the charge level.
• If one LED is flashing, the battery pack is almost flat and must be recharged.

Removing and inserting the battery pack

• Removal: Press the battery pack release button (16) and pull the battery pack (14) forwards .
• To insert: Slide the battery pack (14) in until it engages.

Carrying strap
If necessary, hang the hook on the Metabo carrying strap (7) on the eyelet (8). Set the carrying strap (7) to the desired length.

Carrying:

To prevent unintentional start-up, move the rotation selector switch (9) to centre position (transporting safety device).

Never carry with a tool inserted.
The machine must only be carried with the Metabo carrying strap (7) across chest and back (illustration a, page 2). Hold the machine steady.
The machine must NOT be carried with the carrying strap (7) around your neck (illustration b, page 2).

Use

The machine’s multifunctional monitoring system
If the machine switches off automatically, the machine electronics have activated automatic protection mode. A warning signal sounds (continuous beeping). The beeping stops after a maximum of 30 seconds or when the trigger (10) 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 flat: (the electronics prevent the battery pack form discharging totally and avoid irreparable damage).
   If one LED is flashing, the battery pack is almost flat. (15) If necessary, press the (12) button and check the LEDs (13) 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 switch (10). Switch it on again and continue to work as normal. Try to prevent the machine from seizing.

Depth Stop Setting
Loosen the additional handle (1). Set depth stop (4) to the desired drilling depth and retighten additional handle (1).

On/Off switch, setting the speed
Switching on, speed: press the trigger switch (10). Press in the trigger to increase the rotational speed.
Switching off: Release the trigger switch (10).

Operating mode selection
Press the lock (6) and turn the thumbwheel (5).

  Direct current

The technical specifications quoted are subject to tolerances (in compliance with the relevant valid standards).

Emission values
These values make it possible to assess the emissions from the power tool and to compare different power tools. Depending on the operating conditions, the condition of the power tool or the accessories, the actual load may be higher or lower.
For assessment purposes, please allow for breaks and periods when the load is lower. Based on the adjusted estimates, arrange protective measures for the user e.g. organisational measures.

Vibration total value (vector sum of three directions) determined in accordance with EN 60745:

• ah, HD = Vibration emission value (hammer drilling into concrete)
• ah, Cheq = Vibration emission value (chiselling)
• Kh,HD/Cheq= Uncertainty (vibration)
• Typical A-effective perceived sound levels:
• LpA = Sound-pressure level
• LWA = Acoustic power level
• KpA, KWA= Uncertainty
• During operation the noise level can exceed 80 dB(A).
