DESIGN AND APPLICATION
The angle grinder is a hand-held power tool with the II class isolation.
The power tool is driven with a single-phase, commutator motor,
whose rotational speed is reduced by means of an intersecting axis
gear. The power tool can used both for grinding and cutting. This type
of power tools is widely used for removal of burrs from metal surfaces,
weld surface processing, cutting light-wall tubes and other small metal
objects etc. They are used in engineering industry, automotive and
chemical industry. With the use of proper tools, the angle grinder can
be used not only for cutting or grinding, but also for rust and paint coats
removal.
The areas of its application include repair and construction works, not
only related to metals. The angle grinder can also be used for cutting
and grinding of construction materials, such as brick, paving stones,
ceramic tiles, etc.
The power tool is designed for dry operation only and it must not
be used for polishing. The power tool should be used according to
its purpose.
Use inconsistent with its purpose
• Do not work materials that contain asbestos. Asbestos is carcinogenic.
• Do not work materials, whose dust is inflammable or explosive.
During operation, the power tool produces sparks, which may ignite
emitted vapours.
• Do not use cut-off wheels for grinding. The cut-off wheels are used to
cut with its face, while grinding with lateral surface of such a cut-off wheel
threatens with its damages and puts the operate in danger of injuries.

PREPARATION FOR WORK
ATTACHING THE ADDITIONAL HANDLE
The additional handle ( 3 ) is installed in one of the holes in the grinder
head. It is recommended to use the grinder with the additional handle.
When holding the grinder with both hands (also using the additional
handle), there is less risk of touching the grinder wheel or brush with
your hand, as well as of injuries during recoil.
INSTALLING AND ADJUSTING THE GRINDING WHEEL GUARD
The wheel guard protects the operator against flying broken pieces
and accidental contact with a working tool or sparks. The guard
should always be fitted. Special attention should be paid so that its
covering part faces the operator.
• Install the grinding wheel guard ( 4 ) so the protrusion on its clip
matches the notch on the grinder gear casing.
• The wheel guard can be set in any position.
• Secure the mounting bolt.
The removal and adjustment of the wheel guard are performed in a
reverse order to its installation.
REPLACEMENT OF WORKING TOOLS
When working tools are replaced, wear working gloves at all times.
The spindle lock button (1) is only designed to lock the grinder
spindle, when a working tool is installed or removed. Do not use it
as a braking button, when the wheel rotates. Otherwise, the grinder
may become damaged or the user may be injured.
INSTALLING THE WHEELS
When grinding or cut-off wheels with the thickness below 3 mm are
installed, the outer flange nut (5) should be tightened with the flat
surface from the wheel side (fig. B).
• Press the spindle lock button ( 1 ).
• 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.
WORKING TOOLS WITH THREADED HOLES ARE REMOVED IN THE
REVERSE ORDER.
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
