one minute in a safe position. Do not use damaged or vibrating
grinding tools. Grinding tools should be round. Damaged
grinding tools may break and cause injuries.
• Once a grinding tool is installed and before the grinder is
switched on, check the grinding tool for correct installation and
free rotations, and whether it does not catch the guard.
• The spindle lock button can be activated, only when the grinder
spindle does not move.
• In case of tools adapted for fastening of grinding wheels with a
threaded opening, make sure the grinding wheel thread length is
suitable for the spindle thread length.
• Always secure the workpiece. It is always preferable to secure the
workpiece in a vice or other fastening tool than holding it in your hand.
• If own weight of the workpiece does not guarantee a stable
position, it should be fastened.
• Do not touch cut-off and grinding wheels, before they cool down.
• Do not exert lateral pressure on the grinding or cut-off wheel.
Do not cut a workpiece of a thickness larger than the maximum
cutting depth of the cut-off wheel.
NOTE: The tools is intended for indoor works.
Despite using the construction, which is safe by design itself,
protection means and additional safety features, there is always a
residual risk of injuries during operation.

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.
ADJUSTABLE MAIN HANDLE
Before starting operation you can adjust the main handle to the position
most comfortable for the task. Before starting operation you can adjust
the main handle to the position most comfortable for the task. The
handle can be fixed in
3 different positions by rotating it by 90º to the
left or right in relation to the base position.
• Press the main handle lock button ( 9 ).
• Rotate the main handle to a desired position.
• The main handle will automatically lock in the position.
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.
