Special Safety Instructions

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.

Use clamps or another practical way to secure and support the workpiece to a stable platform.
Holding the work by your hand or against the body leaves it unstable and may lead to loss of control.
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).
Therefore, always hold the machine with both hands using the handle provided, stand securely and concentrate.
Keep hands well away from the sawing area and the saw blade. Do not reach underneath the workpiece.
Remove chips and similar material only with the machine at a standstill.
Danger of injury due to the sharp accessories. Wear protective gloves.
After stopping work, the tool may still be hot. Wear protective gloves.
Danger of crushing when changing the tool. Wear protective gloves.
Do not keep the ventilation slots closed.
Do not process surfaces that are impregnated with liquids containing solvents! Do not process wet coatings! The surface heats up during processing and toxic vapours may develop.

WARNING – Always wear protective goggles.
Wear ear protectors when working for long periods of time. High noise levels over a prolonged period of time may affect your hearing.
CAUTION Do not stare at operating lamp. LED light (1): do not observe the LED radiation directly with optical instruments.

4.1 Special safety instructions for cordless machines:
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 or short circuit battery pack contacts!
**** 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.
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).

4.2 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 wellventilated 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 towards yourself or nearby persons or towards dust deposits,
– use an extraction unit and/or an air purifier,
– ensure good ventilation of the workplace and keep it clean using a vacuum cleaner. Sweeping or blowing stirs up dust.
– Vacuum or wash protective clothing. Do not blow, beat or brush protective gear.

Initial Operation

Battery pack
Charge the battery pack (5) before use.
Recharge the battery pack if performance diminishes.
Instructions on charging the battery pack can be found in the operating instructions of the Metabo charger.
In case of Li-Ion battery packs with capacity and signal display (10) (equipment-specific):
– Press the button (9); the LEDs indicate the charge (10) level.
– The battery pack is almost empty and must be recharged if one LED is flashing.
Removing and inserting the battery pack
Remove: Press the battery pack release button (6) and remove battery pack (5).
To insert: Slide the battery pack (5) in until it engages.

Use

7.1 Attaching the accessory
Prior to any conversion work: remove battery pack from machine.
Danger of injury due to the sharp accessories.
After stopping work, the tool may still be hot.
Danger of crushing when changing the tool. Wear protective gloves.
**** Use only sharp, undamaged saw blades. Do not use accessories that are cracked or that have changed their shape. Use an accessory that is suitable for the material being sawn.
See Fig. A, page 2.

1. Place the accessory (12) in the desired position onto the tool holder (11) . Ensure that it engages in the cams of the tool holder (11) .
2. Tighten clamp screw (8) with hexagon spanner (7).
3. Check the accessories for firm hold.

7.2 Installation of sanding disc

Troubleshooting

8.1 The machine’s multifunctional monitoring system
If the machine switches off automatically, the machine electronics have activated automatic protection mode.
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 (the electronics prevent the battery pack from discharging totally and avoid irreparable damage).
   If one LED (10) is flashing, the battery pack is almost empty. If necessary, press the button (9) and check the LED lamps (10) to see the charge level. If the battery pack is almost empty, 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. The machine does not run and the LED light (1) flashes. Restart protection is active. The machine will not start if the battery pack is inserted while the machine is on. Switch the machine off and back on again.
