Threaded mounting of accessories must match the grinder spindle thread. The dimensions of the hole in which wheels,
disks, flanges and other accessories are installed must comply with the dimensions of the spindle of the tool. Acces-
sories in which the dimensions of the fixing hole do not comply with the dimensions of the spindle of the tool, will vibrate after start,
which may preclude a proper control of the tool.
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 flying pieces generated during work. The dust mask must filter 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 inflammable materials. The sparks generated during work may cause a fire.
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 firmly 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 flicking 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 grinding and cutting with abrasive disks
Use only disks which are adequate for the tool and guards designed for the given type of disk. Disks which are not compat-
ible with the tool cannot be properly protected and are not safe.
The grinding surface of centre depressed wheels must be mounted below the plane of the guard lip. An improperly
mounted wheel that projects through the plane of the guard lip cannot be adequately protected.
The guard must be secured to the tool and placed in a position which ensures maximum safety, so that the smallest
possible area of the disk is unprotected towards the operator. The guard helps to protect the operator from broken fragments
of the disk and prevents accidental contact with the disk.
