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.

•

Move the lever switch (

7

) forward.

•

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.

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).

• Do not grind with the entire surface of a wheel.

• This disc type should be used for working flat surfaces.

Wire brushes are mainly used for cleaning sections and hard-to-
reach spaces. They can be used to remove rust, painting coats, etc. 
from a workpiece surface (fig. K).

Only such working tools can be used, whose permissible 
rotational speed is higher or equal to the maximum no load speed 
of the grinder.

OPERATION AND MAINTENANCE

Before any operations related to installation, adjustment, repairs 
or maintenance are commenced, the plug of the power cord 
should be disconnected from the socket.

MAINTENANCE AND STORAGE

•

It is recommended to clean the tool after each use.

•

Do not use water or other fluids for cleaning.

•

The tool should be cleaned with a dry piece of cloth or blown with 
compressed air of low pressure. 

•

Do not use any cleaning agents or solvents, since they may damage 
plastic parts.

•

Venting slots in the motor housing should be cleaned on a regular 
basis not to overload the tool.

•

When the power cord is damaged, it should be replaced with 
the power cord of the same parameters. It should be performed 
by a qualified professional or the tool should be delivered to an 
authorised service shop.

•

When the commutator sparks excessively, have the condition of 
motor carbon brushes checked by a qualified person.

•

The tool should be always stored in a dry place and out of reach 
of children.

REPLACING THE CARBON BRUSHES

Worn (shorter than 5 mm), burnt or cracked motor carbon brushes 
should be immediately replaced. Both carbon brushes should be 
always replaced at the same time.
Carbon brushes should be replaced by a qualified person using 
original spare parts only.
