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.
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. The grinder is equipped with the switch
protecting against accidental activation.
• Press the safety button (7).
• Press the switch button (2) (fig. C).
• When the switch button (2) is released, the grinder stops.
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.
SPEED ADJUSTMENT
The speed adjustment dial (11) (fig. L) is located in the upper rear
part of the grinder casing. The adjustment range is from 1 to 6. The
rotational speed can be changed depending on your needs.
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).
