Do not use damaged accessories. Before each use, make sure the accessories are not splintered, broken or excessively
worn. If accessories are dropped make sure they are not damaged or install new accessories. Once accessories have
been inspected and installed, all persons must remain away from the plane of rotation of the accessories, and start the
tool for a minute with the maximum rotational speed. During the test damaged accessories will be destroyed.
Use individual protection means. Depending on the job, wear face protections or safety goggles. If it is required use dust
masks, hearing protectors, gloves and aprons protecting from small fragments of the accessories or materials generated
during work. Eye protection must stop fl ying pieces generated during work. The dust mask must fi lter dust generated during work.
Excessive exposition to noise may lead to hearing impairment.
While realising tasks during which the disc may come into contact with a hidden live electric wire or a power supply
cable hold the grinder by insulated handles. If the disc touches a live wire, the metal elements of the tool may cause electric
shock to the operator of the tool.
Maintain a safe distance between the place of work and third persons. Persons who approach the place of work must
use individual protection means. Chips generated during work or fragments of damaged accessories may be ejected beyond
the direct vicinity of the place of work.
Place the power supply cord away from the rotating wheels. In case the operator loses the control over the tool, the cord may
be cut or caught, and the hand or arm of the operator may be drawn into the rotating elements of the machine.
Never put down the tool until the rotating elements have stopped completely. The rotating elements may „catch” the ground
and impede the control of the tool.
Do not start the tool while carrying it. Accidental contact with the rotating elements may cause drawing clothes and contact of
the tool with the body of the operator.
Clean the ventilating holes of the tool regularly. The ventilator of the motor pulls the dust generated during work into the tool.
Excessive accumulation of metal particles contained in the dust increase the risk of electric shock.
Do not operate the tool in the vicinity of infl ammable materials. The sparks generated during work may cause a fi re.
Do not use accessories which require cooling with liquids. Water or cooling liquid may cause an electric shock.
Warnings related to the possibility of the tool rebounding towards the operator
Rebounding of the tool towards the operator is caused by a sudden reaction to blocked or seized discs or polishing belts or another
accessory, which causes a sudden stop of the rotating accessory and a turn of the electric tool opposite to the direction of rotation.
For example, if the grinding disc is seized by the object being processed, the edge of the disc, which is at the point of seizure may
get deeper into the surface of the material, and thus get ejected.
The disc may also move towards or away from the operator, depending on the direction of movement of the grinding wheel at the
place of seizure. Grinding wheels may also break.
Rebounding of the tool towards the operator is caused by incorrect operation and / or inobservance of the indications contained
in the operating manual. It may be prevented if the following recommendations are followed.
Hold the tool fi rmly and adopt an adequate position of the body and the hands, which will permit you resist the force
generated when the tool rebounds. Always use the additional handle, if it has been supplied with the tool, which will
ensure a maximum control when the tool rebounds or turns inadvertently during start. The operator is able to control the
turning or rebound of the tool, if adequate safety measures have been taken.
Do not ever place hands close to the rotating elements of the tool. The rotating elements may, in case the machine rebounds,
get into contact with the hand.
Do not remain within the area into which the tool will move in case of rebound. A rebound will propel the tool in the direction
opposite to the rotation of the grinding disk, where it is seized.
Be particularly careful during work close to corners, sharp edges, etc. Avoid fl icking up and seizure of the grinding disk.
During work on corners or edges there is an increased risk of seizure of the grinding disk, which may imply a loss of control over
the tool or rebound of the tool.
Do not use disks with cutting chains or disk saws. The edges cause frequent rebounds, which may lead to a loss of control
over the tool.
Warnings related to polising operations
Do not allow any loose portion of the polishing bonnet or its attachment strings to spin freely. Tuck away or trim any
loose attachment strings. Loose and spinning attachment strings can entangle your fi ngers or snag on the workpiece.
Warnings related to grinding with abrasive paper
Do not use discs with abrasive papers of an excessive size. While selecting the grinding wheel, follow the guidelines of
the manufacturer. Abrasive paper which signifi cantly exceeds the size of the disc may cause injuries and increases the risk of
seizure, tearing or rebounding towards the operator.
PREPARING THE MACHINE FOR OPERATION
Warning! Before installation, replacement or removal of accessories, make sure that the battery is disconnected from the tool and
that the switch is locked.
