EQUIPMENT AND ACCESSORIES
1. Grinding wheel guard - 1 pce
2. Socket spanner - 1 pce
3. Additional handle - 1 pce
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 ying broken
pieces and accidental contact with a working tool or sparks. The
guard should always be tted. Special attention should be paid so
that its covering part faces the operator.
• The design of the wheel guard mounting allows for toolless
setting of the guard in an optimum position.
• Loosen and pull back the lever (10) on the wheel guard (4).
• Rotate the wheel guard (4) in a selected position.
• Lock by lowering the lever (10).
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-o wheels with the thickness below 3 mm
are installed, the outer ange nut (5) should be tightened with the
at surface from the wheel side (g. B).
• Press the spindle lock button (1).
• Insert the special key (included) into two holes of the outer ange
(5) (g. A).
• Rotate the key to loosen and remove the outer ange (5).
• Place the wheel so it is pressed against the surface of the inner
ange (6).
• Tighten the outer ange (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 ange (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 anges should be removed before installation – the inner
ange (6) and outer ange (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 o 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
sucient pressure to eciently 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) (g. 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 o.
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 o. 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.
SPEED ADJUSTMENT
The speed adjustment dial (8) (g. 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-o wheel to vibrate or jump, since this will
lower the quality of cutting and may cause the cut-o wheel to
break.
• Do not exert lateral pressure onto the cut-o wheel during
cutting.
• A proper cut-o 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-o wheel.
The cutting depth depends on a wheel diameter (g. G).
• Only wheels with nominal diameters not larger than
recommended for a given grinder model should be used.
• Do not allow the fastening anges to contact a workpiece in case
of deep cuts (e.g. sections, building blocks, bricks, etc.).
Cut-o wheels reach high temperatures during operation. It
cannot be touched with uncovered body parts, before they cool
down.
