• 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, 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).

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.

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.
