presence of cracks and abrasion, polishing wheels for the presence of cracks, abrasion and excessive use, wire brushes
for the presence of loosened or cracked wires. In case of dropping of accessories they must be examined for damages or
new, undamaged accessories should be installed. Once the accessories are examined and installed, you and other third
parties should stay out of the plane of rotation of accessories, and then start the tool for one minute at the maximum
rotational speed. Damaged accessories shall be destroyed during the test.
Use personal safety equipment. Depending on application, use protection of faces, goggles or safety glasses. If it is
required, use anti-dust masks, hearing protections, gloves or aprons protecting from small parts of accessories or
materials produced during operation of the tool. Eye protection must be able to stop fl ying chips produced during operation
of the tool. Anti-dust mask must be able to fi ltrate the dust produced during operation of the tool. Too long exposure to noise may
result in loss of hearing.
Maintain safe distance between the workplace and outsiders. Persons accessing the workplace must use personal
safety equipment. Chips produced during the work or chips of damaged accessories may fl y out of immediate vicinity of the
workplace.
While working, where the inserted tool may come into contact with hidden live wire, hold the power tool using insulated handles.
Inserted accessory when coming into contact with a live wire may cause metal components of the tool to become energized, which
could result in electric shock to the tool operator.
Firmly hold the tool in your hand (hands) during the start. The torque of the engine accelerating to full speed can cause the
rotation of the tool.
When possible, use the clamps to hold down the workpiece. Never hold the small workpiece in one hand and the tool
in the other hand during the work. Using clamps for fastening small workpiece will allow controlling the tool with your hands.
Round materials such as spindles and pipes tend to rotate during cutting and may cause a jam or sudden movement towards
the operator.
Place the power cable out of rotating tool components. In case the control of tool is lost, the cable may be cut or seized, and
the operator's hand or arm may be drawn into rotating tool's components.
Never put aside the tool until all rotating elements are stopped completely. Rotating elements may "seize" the substrate and
get the tool out of control.
After the replacement of inserted accessory or any adjustment, always make sure that the nut of the spindle, tool chuck
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,
