GRAPHITE 59G110 [15/100] Operation and maintenance
15
• This disc type should be used for working at 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 (g. 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 qualied person using
original spare parts only.
All types of faults and defects should be eliminated by an authorised
service of the manufacturer.

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) (g. 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 o. 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-o wheel to vibrate or jump, since this
will lower the quality of cutting and may cause the cut-o
wheel to break.
• Do not exert lateral pressure onto the cut-o wheel during
cutting.
• A proper cut-o 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-o wheel.
The cutting depth depends on a wheel diameter (g. 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-o 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-o 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° (g. H).
• Works related to grinding can be performed only, when
proper grinding discs are used for a given workpiece.
When ap wheels, discs with abrasive bre and exible discs for
sandpaper are used, attention should be paid to the proper tool
angle (g. I).
• Do not grind with the entire surface of a wheel.
