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
Immediately replace worn out (shorter than 5 mm), burnt or cracked
motor carbon brushes. Always replace both carbon brushes at a
time.
• Unscrew and remove carbon brush covers (7) (fig. E).
• Pull the pressure spring away, snap out and remove worn out
carbon brushes.
• Remove any carbon dust with compressed air.
• Install new carbon brushes (they should easily slide into the brush
holders) and reinstall the pressure spring (fig. F).
• Fix carbon brush covers (7).
After the carbon brushes are replaced, switch on the grinder
with no load and wait for 1-2 minutes to make the carbon
brushes fit the motor commutator. Carbon brushes should be
replaced by a qualified person using original spare parts only.
All types of faults and defects should be eliminated by an authorised
service of the manufacturer.
