or any adjustment tool has been fi rmly tightened. Loosened adjustment tool may unexpectedly displace and cause the loss of
control, loosened and rotating elements will be ejected at high speed.
Do not start the tool while carrying it. Accidental contact with rotating elements may cause the clothes being seized and drawn
in and contact of tool with operator's body.
It is required to clean the ventilation slots of the tool on regular basis. Motor's fan sucks up the dirt and dust produced during
operation of the tool to the interior of the tool. Excessive accumulation of metals particles contained in dust increases the threat
of electric shock.
Do not operate the tool close to fl ammable materials. Sparks produced during the work may cause a fi re.
Do not use accessories that require cooling liquid. Water or cooling liquid may cause electric shock.
Warning associated with a risk of rebound of tool in direction of operator.
Rebound of tool in direction of an operator is a result of sudden reaction to locked or clamped: rotating disc, polishing belt, brush
or other accessories. Locking or clamping causes sudden stoppage of the rotating accessory which results in rotation of power
tool in a direction opposite to rotation of an accessory.
For example, if the abrasive wheel is locked or clamped by the workpiece, the edge of wheel entering the point of clamping may
penetrate the surface of material, causing the wheel getting out or being ejected. The wheel may also get out in direction of an
operator or in opposite direction, depending on direction of motion of abrasive wheel at clamping point. Abrasive wheels may also
crack under such conditions.
Rebound of tool in direction of an operator is a result of improper use and/or failure to comply with instructions contained in this
manual. This phenomenon may be avoided by adhering to recommendations.
Apply the secure grip of the tool and proper posture of the body and hands, this will allow counteracting the rebound
forces. An operator is able to control the rotation or rebound of tool if proper precautions are taken.
Special precautions should be taken during the work close to corners, sharp edges etc. Avoid bumping and binding of grinding
wheel. When processing corners or edges, there is an increased risk of binding of grinding wheel which leads to loss of control
of tool or rebound of tool.
Do not use circular saws with teeth. Blades cause repeated rebounds and loss of control of tool.
Always insert the tool into the material in the same direction in which the edge of cutting exits the material (direction of
ejection of chips). Inserting the tool in wrong direction will make the cutting edge of the tool inserted exits the material and pulls
the tool in this direction.
When using rotating fi les, cutting wheels, high-speed cutters made of self-bonded carbide, always fasten the workpiece
safely. These accessories may be seized if they are slightly tilted in saw cut and cause the rebound. If a cutting wheel is seized,
it usually breaks. If a rotating fi le or cutter made of self-bonded carbide is seized, it may get out of the saw cut and cause loss of
control of tool.
Warnings related to grinding and cutting by means of abrasive wheels
Use only discs designed to work with the tool and guards designed for the particular type of job. For example, do not
grind using the edge of cutting wheels. Abrasive wheels for cutting are designed for peripheral load; lateral forces applied to
such wheel can make it fall to pieces.
In case of threaded abrasive cones and studs, use only undamaged shafts of plates with fl at fl ange of the right size and
length. The use of correct shaft will reduce the risk of cracking.
Do not "jam" the cutting wheels or apply too much pressure to them. Do not try to increase the cutting depth. Excessive pressure
on wheel increases the load, torsion and abrasion resistance during cutting, and the likelihood of a rebound or damage to wheel.
Do not place your hands in the line and behind the spinning wheel. If in the course of work the disc moves away from your
hands, then in the case of rebound the rotating wheel and tool will be directed towards the operator.
If the wheel has been seized, locked, or in the event of discontinued cutting for any reason, turn off the tool and hold it
idle until the wheel stops completely. Never attempt to release a cutting wheel from a saw cut if the wheel is in motion,
otherwise it may cause a rebound. Investigate the causes and take the correct steps to eliminate the cause of locking the wheel.
Do not resume cutting in the workpiece. Let the wheel reach full rotational speed, and then carefully resume cutting. The
wheel may be locked, get out of the material or bounce if the power tool is started while in the workpiece.
In order to avoid wheel clamping or bouncing, you have to support panels and other oversized materials. Large-size
materials tend to bend under their own weight. Supports must be placed under the workpiece near the line of cutting and near the
edge of the material on both sides of the cutting line.
Special caution must be taken when cutting cavities in walls or other surfaces. The wheel can cut gas and water pipes or
electric cables, as well as objects that will cause a rebound.
Warnings related to work with wire brush
Caution must be taken, because the wire splinters are ejected out of the brush also during normal operation. Do not
overload the wires by applying excessive force to the brush. Wires can easily puncture light clothing and/or skin.
