• Do not use the grinding wheel for hammering or stripping of the workpiece, especially when corners,
sharp edges are worked, etc. (this may cause loss of control of the power tool and recoil).
• Do not use discs from circular saws intended for wood cutting. Failure to observe this recommendation
may result in recoil of the power tool, loss of control and may lead to injuries of the operator.
SWITCHING ON /SWITCHING OFF
When the grinder is switched on and operated, it should be held with both hands.
• Press the rear part of the switch (2).
• Move the switch (2) forwards - (towards the head) (fig. C).
• Press the front part of the switch for continuous operation.
• The switch will be automatically locked in the position for continuous operation.
• Press the rear part of the switch (2) to switch the tool off.
Once the grinder is switched on, wait until the grinding wheel reaches maximum speed and only
then you can begin to work. During operation do not use the switch to switch the grinder on and off.
The grinder switch can be used only when the power tool is moved away from the workpiece.
The tool is equipped with a switch with undervoltage release feature. In case of temporary mains
power failure or connecting to mains socket with switch in ON position, the tool will not start. In such
case move the switch to OFF position and switch it on again.
CUTTING
• The angle grinder can be used for cutting in a straight line only.
• Do not cut a workpiece holding it in your hands.
• Large workpiece should be supported. Make sure the support points are located near the cutting line
and at the ends of the workpiece. A stably located workpiece will not tend to move, when it is cut.
• Small workpieces should be fastened in a vice or using clamps, for example. The workpiece should
be fastened so that it is cut near the fastening element. This will ensure higher cutting precision.
• Do not allow the cut-off wheel to vibrate or jump, since this will lower the quality of cutting and
may cause the cut-off wheel to break.
• Do not exert lateral pressure onto the cut-off wheel during cutting.
• A proper cut-off wheel should be used depending on a workpiece type.
• When a workpiece is cut, it is recommended that a cutting direction is the same as rotation direction
of the cut-off wheel.
The cutting depth depends on a wheel diameter (fig. G).
• Only wheels with nominal diameters not larger than recommended for a given grinder model should be
used.
• Do not allow the fastening flanges to contact a workpiece in case of deep cuts (e.g. sections, building
blocks, bricks, etc.).
Cut-off wheels reach high temperatures during operation. It cannot be touched with uncovered
body parts, before they cool down.
GRINDING
Grinding wheel, cup-type grinding wheels, flap wheels, wheels with abrasive fibre, wire brushes and flexible
discs, etc. should be used for grinding. Each type of discs and workpiece requires proper working method
and personal protective equipment.
Cut-off wheels should not be used for grinding.
Grinding discs are intended for removal of material with an edge of the disc.
• Do not use the lateral surface for grinding. The optimum working angle for this disc type is 30° (fig. H).
• Works related to grinding can be performed only, when proper grinding discs are used for a given
workpiece.
When flap wheels, discs with abrasive fibre and flexible discs for sandpaper are used, attention
should be paid to the proper tool angle (fig. I).
