Specified Conditions of Use
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 – Read the operating instructions to reduce the risk of injury.
WARNING – Read all safety warnings, instructions, illustrations and
specifications provided with this power tool.
Failure to follow all instructions listed below may result in electric shock,
fire and/or serious injury.
Save all warnings and instructions for future reference. Always include these
documents when passing on your power tool.
Special Safety Instructions
3.1 Safety instructions for all operations
a) Wear ear protectors. Exposure to noise can cause hearing loss.
b) Use auxiliary handle(s), if supplied with the tool. Loss of control can
cause personal injury.
c) Hold the power tool by insulated gripping surfaces, when performing an
operation where the cutting accessory or fasteners may contact hidden wiring
or its own cord. Cutting accessory contacting a “live” wire may make exposed
metal parts of the power tool “live” and could give the operator an electric
shock.
3.2 Safety instructions when using long drill bits with rotary
hammers
a) Always start drilling at low speed and with the bit tip in contact with the
workpiece. At higher speeds, the bit is likely to bend if allowed to rotate
freely without contacting the workpiece, resulting in personal injury.
b) Apply pressure only in direct line with the bit and do not apply excessive
pressure. Bits can bend, causing breakage or loss of control, resulting in
personal injury.
3.3 Further Safety instructions
Always work with the additional handle correctly installed.
Always hold the machine with both hands at the intended handles, take a secure
stance and concentrate on the work. Wear personal protective equipment and
always wear safety glasses. Protective equipment such as dust mask, non-skid
safety shoes, protective gloves, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.
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).
If the safety coupling responds, switch off the machine immediately.
Do not touch the rotating tool!
Secure the workpiece to prevent slipping or rotation (e.g. by securing with
screw clamps).
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.
Pull the plug out of the socket before making any adjustments, changing tools,
carrying out maintenance or cleaning.
Avoid inadvertent starts by always unlocking the switch when the plug is
removed from the mains socket or whenever the power fails.
A damaged or cracked additional handle must be replaced. Never operate a
machine with a defective additional 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.
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.
