Insert the special key (included) into two holes of the outer flange
(5) (fig. A).
Rotate the key to loosen and remove the outer flange (5).
Place the wheel so it is pressed against the surface of the inner
flange (6).
Tighten the outer flange (5) and slightly tighten it with the special
key.
The wheel is removed in the reverse order. During installation, the
wheel should be pressed against the surface of the inner flange (6)
and seated centrally in the neck.
INSTALLING THE WORKING TOOLS WITH THREADED HOLES
Press the spindle lock button (1).
Remove a previously installed working tool, if it is installed.
Both flanges should be removed before installation – the inner
flange (6) and outer flange (5).
Put the threaded part of a working tool onto the spindle and
slightly tighten.
Working tools with threaded holes are removed in the reverse order.
INSTALLING THE ANGLE GRINDER ON A TRIPOD FOR ANGLE
GRINDERS
The angle grinder can be used on a dedicated tripod for angle
grinders, provided that it is correctly installed according to
instructions of the manufacturer of a tripod.
OPERATION / ADJUSTMENTS
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.
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).
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
