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 the 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!
If the machine is defective, remove the battery pack from the machine.
LED lights (15): 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, and asbestos. Other known diseases are e.g. allergic reactions and 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, and 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 it 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 packs 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).

Commissioning

6.1 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.
6.2 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), and the LEDs indicate the charge level.
• If one LED is flashing, the battery pack is almost flat and must be recharged.

6.3 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.
6.4 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.

Use

7.1 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 from 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.
