Warnings related to grinding and cutting
Use only discs intended for work with a chosen tool and guards designed for a given type of disc. The discs for which the
tool is not designed cannot be properly guarded and are not safe.
The convex disc must be mounted in such a way that the grinding surface does not protrude beyond the plane of the pro-
tective fl ange of the guard. An incorrectly mounted disc that protrudes above the guard poses a risk to safety during operation.
The guard must be securely attached to the tool and positioned for maximum safety so that the smallest possible area
of the disc is exposed towards the operator. This guard helps to protect the operator from broken disc fragments and prevents
accidental contact with the disc.
The disc must be used as intended. For example, do not grind with a cutting disc. Grinding wheels for cutting are designed
for circumferential load, lateral forces applied to such a disc may cause it to disintegrate.
Always use undamaged fi xing fl anges, which are the correct size for the grinding wheel. The correct fi xing discs of the
grinding wheel reduce the possibility of damage to the grinding wheel. The fi xing discs for cutting discs can be di ff erent from the
fi xing discs for grinding wheels.
Do not use worn grinding wheels from larger tools. A larger diameter grinding wheel is not suited for a higher rotational speed
of smaller tools and may break.
If you use dual-purpose discs, always use a guard appropriate for the type of work. The use of the wrong guard may lead
to the failure to provide the desired degree of protection, which can lead to serious injury.
Warnings related to cutting
Do not “jam” the disc or apply too much pressure. Do not try to cut too deep. Excessive stress of the grinding wheel in-
creases load and susceptibility for twisting or catching the disc in the cut groove, which increases the risk of kickback towards the
operator or disc damage.
Do not place your body in the cutting line or behind the rotating grinding wheel. If during operation, the grinding wheel
rotates in the direction away from the operator’s body, the kickback towards the operator can direct the rotating disc and tool
towards the operator.
If the disc is caught or the cut is interrupted for any reason, turn o ff the tool then keep it at a standstill until the disc
rotation stops completely. Never attempt to get the rotating cutting disc out of the groove as it may result in kickback
towards the operator. It is recommended to fi nd causes and take appropriate steps to prevent the disc from being caught.
Do not resume cutting in the material. Allow the disc to achieve its nominal rotational speed and only then carefully
insert it into the cut groove. The disc may be clamped, pulled out, or kicked back towards the operator if the cut is resumed
in the material.
Support panels and other oversized materials to minimise the risk of clamping and kickback towards the operator . Over-
sized materials tend to bend under their own weight. The supports must be placed under the material close to the cutting line and
close to the edge of the material on both sides of the cutting line.
Take special care when performing deep cuts in the walls or other unknown surfaces. A protruding disc may cut through
gas pipes, electric cables, or other objects that may cause a kickback towards the operator.
Do not attempt to cut following the shape of an arc. Overloading the disc increases its load and susceptibility to twisting or
jamming in the cut groove and the likelihood of kickback towards the operator or disc damage, which can lead to serious injury.
Warnings related to grinding with sandpaper
Use sandpaper in the correct size. When selecting a disc, follow the manufacturer’s recommendations. A sandpaper that
protrudes well beyond the disc may cause injury, and also increase the risk of jamming, tearing or kickback towards the operator.
Warnings related to the work with the wire brush
Be careful, as wire fragments are also ejected from the brush during normal operation. Do not overload the wires by
applying too much pressure to the brush. The wires can easily pierce thin clothing or skin.
If the use of guards is recommended during the work with the wire brush, prevent any contact of the brush with the
guard. The wire brush can increase its diameter under load and centrifugal force.
Safety warnings related to polishing
Do not allow any loose part of the polishing disc or fastening cord to rotate freely. Loose and rotating cords can entangle
in the fi ngers or be caught in the workpiece.
INSTALLATION OF THE EQUIPMENT
Install the grinding disk guard
Place the disc guard on the cylindrical section of the body around the spindle and using screws or a clamping ring fi x it so that the
guard is straight and safe. Position the grinding disk guard so that the unprotected area of the disk is as far as possible from the
hand which holds the handle. Do not ever work with the grinder without a properly installed disk guard!
The grinder is provided along with a protection which guarantees proper protection only while grinding with abrasive discs and
discs with abrasive paper as well as certain wire brushes. Once installed on the spindle, the disc must not protrude beyond the
