Before the grinder is used, check condition of the grinding wheel. Do not use chipped, broken or
otherwise damaged grinding wheels. Worn grinding wheel or brush should be immediately replaced
with new one before use. Once your work is completed, you should switch off the grinder and wait
until it comes to a complete stop. Only then the grinder can be put aside. Do not brake a rotating
grinding wheel by pressing it against a workpiece.
Do not overload the grinder. The weight of the power tool exerts sufficient pressure to efficiently
work with the tool. Overloading and excessive pressure may lead to dangerous cracking of the
working tool.
If the grinder is dropped during operation, it should be checked and a working tool might need to
be replaced, when it is damaged or deformed.
Never strike the workpiece with a working tool.
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. The grinder is
equipped with the switch protecting against accidental activation.
Press the safety button ( 7).
Press the switch button ( 2) (fig. C).
When the switch button ( 2) is released, the grinder stops.
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.
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.
