The maximum rpm of the accessories must be equal to or greater than the maximum rpm of the tool. Accessories with a
lower rotational speed than the tool speed can disintegrate during operation.
The outer diameter and thickness of accessories must be within the size range specifi ed for the tool. It is not possible to
properly guard or operate improperly sized accessories.
The size of the hole used for fi xing wheels, discs, fl anges and other accessories must match the size of the tool spindle.
Accessories with a fi xing hole size not suitable for the tool spindle size will start to vibrate during operation, which may result in
the loss of control of the tool.
Do not use damaged accessories. Before each use, examine the condition of the accessories for possible splinters,
cracks, abrasions and excessive wear. If any accessories are dropped, make sure they are not damaged, or mount new,
undamaged accessories. After you have checked and installed the accessories, make sure you and all bystanders stand
outside the rotation plane of the accessories, then run the tool for one minute at maximum speed. Damaged accessories
will disintegrate during the test.
Wear personal protective equipment. Use face shields, goggles or safety goggles, depending on the application. If re-
quired, use dust masks, hearing protection, safety gloves and aprons to protect against small pieces of accessories or
materials generated during work. The eye protection must be capable of stopping any fl ying debris generated during work. The
dust mask must be capable of fi ltering out dust generated during work. Exposure to noise for too long can result in hearing loss.
When carrying out work in which the disc may come into contact with a live, concealed electrical wire or power cord, grip
the sander's insulated handles only. When in contact with a live wire, the disc can result in metal parts of the tool becoming live,
which can lead to the tool operator suff ering electric shock.
Ensure all bystanders keep a safe distance from the work area. Persons entering the work area must wear personal
protective equipment. Debris or pieces of damaged accessories which are generated during work can be thrown out of the
immediate vicinity of the work area.
Keep the power cord away from rotating tool parts. If you lose control of the tool, the cord can be cut or caught, and your hand
or arm can be drawn into the rotating parts of the machine.
Never put down the tool until the rotating parts have come to a complete standstill. The rotating parts can "catch" the fl oor
and pull the tool out of your control.
Do not run the tool while carrying it around. Inadvertent contact with rotating parts can cause your clothes to catch and be
pulled in by the tool, which can come into contact with your body.
Clean the tool's ventilation openings regularly. The motor fan draws dust generated during operation inside the tool. Excessive
accumulation of metal particles contained in the dust increases the risk of electric shock.
Do not use the tool near fl ammable materials. Sparks generated during operation may cause fi re.
Do not use accessories which require liquid cooling. Water or coolant may cause electric shock.
Dust from sanding surfaces can be toxic. Avoid inhaling it, use respiratory protection and dust extraction system.
Caution! Tool kickback towards the operator
The kickback of the tool towards the operator is caused by a rotating disc, brush, polishing tape or other accessories, when
suddenly blocked or clamped. Blocking or clamping causes a rotating accessory to stop suddenly, which results in the power tool
rotating in the opposite direction to the accessory rotation.
For example, if the sanding disc is blocked or clamped by the workpiece, the edge of the disc which reaches the clamping point
can sink in the surface of the material, causing the disc to escape or be ejected.
The disc can also escape towards or away from the operator, depending on the direction of the wheel movement at the clamping
point. Sanding discs may also break in these conditions.
The tool kickback towards the operator is a result of misuse and/or failure to follow the guidelines in the User Manual. This occur-
rence can be avoided by following the instructions below.
Use a fi rm grip on the tool and the correct position of the body and hands to withstand the forces generated by the
kickback. Always use an additional handle, if supplied with the tool, to ensure maximum control during the kickback or
any unexpected rotation during the tool start. The operator will be able to control the tool rotation or the kickback if appropriate
precautions are taken.
Keep your hands away from rotating tool parts. The rotating parts can come into contact with your hands, when kicked back.
Do not stand in the area where the tool may kick back. The kickback will direct the tool in the opposite direction to the direction
of the sanding disc rotation, at the clamping point.
Pay special attention when working near corners, sharp edges, etc. Prevent the sanding disc from axial displacement
and being jammed. When working corners or edges, there is an increased risk of the sanding disc jam, leading to a loss of control
or tool kickback.
Do not use cutting chain discs or circular saws. The blades cause frequent kickbacks and the loss of control of the tool.
Caution! Sanding with sanding sheets
Do not use oversized sanding discs. When selecting a wheel, follow the manufacturer's recommendations. A sanding
sheet which protrudes well beyond the disc may cause injury, and also increase the risk of jamming, tearing or kickback towards
the operator.
