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.
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.
• Move the lever switch ( 7 ) forward.
• 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 ( 8 ) ( fig. D ) 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.
