Put the protective guard (8a; 8b) on the clamping collet (6). The guide
lugs (9) must be inserted into the grooves on the clamping collet. Set the
protective guard (8a; 8b) to the requested working position.
Note: The protective guard has been designed so that no tool may be
needed for fixing the protective guard in the requested working position.
Attention! For safety reasons the clamping bolt (10) has been tight-
ened in the manufacturing plant by the torque 3.5 Nm so that the
safety guard may not be loose on the clamping collet (6), but may be
swiveled by hand after overcoming the set resistance. It is necessary
to check the mounted protective guard - it may not be loose (may not
wobble) on the clamping collet. For possible tightening the clamp-
ing bolt (10) use the hexagonal wrench dia. 4 mm (18) and check the
torque 3.5 Nm.
Additional handle
The additional handle (17) can be screwed from the left or right gearbox (5)
side or from the top gearbox (5) part.
Additional handle VIBRASTOP (not EBU 13-9)
Thanks to the special design “VIBRASTOP“ vibrations are reduced by the ad-
ditional handle (17).
Grinding or cutting wheel fixing
Attention! Prior to handling the accessories, the power supply cable
has always to be disconnected from the power source socket.
Clean the bottom flange (11) and the clamping nut (14) as well as the
clamping surfaces of the grinding or cutting wheel. Place the bottom
flange (11) (by the recess out) on the spindle (7). Place the grinding (12)
or cutting wheel (13). The bottom flange recess (14) must be inserted pre-
cisely into the grinding wheel (12) or the cutting wheel (13) hole. Then put
the clamping nut (14) on the spindle (7) so that when fixing the grinding
wheel (12), the clamping nut recess (15) must be faced towards the wheel
and when fixing the cutting wheel (13), the clamping nut recess (15) must
be directed from the wheel!
Depress the lock spindle pin (3).
Attention! Use the lock spindle pin (3) only if the spindle is at rest and
the grinder is de-energized.
Swivel the wheel /spindle, until the lock spindle pin (3) is engaged. Tighten
the clamping nut (14) firmly, using the wrench (16).
Attention! Prior to starting the grinder, verify that the wheel does
not rotate freely between the bottom flange (11) and the clamping
nut (14).
Putting into operation
Check whether the data on the rating plate match with the real power
supply voltage. The tool intended for 230 V~ may be also connected to
220/240 V~. Check whether the plug type corresponds to the socket type.
Switching on
Push the switch (1) forwards, thus switching the machine on. If you depress
the front switch button part (1), the switch will be arrested in the ON posi-
tion.
Switching off
By releasing the switch button (1), the switch will be returned to the initial
position and the machine will be switched off. If the switch (1) is arrested

Double insulation
To ensure maximum safety of the user, our tools are designed and built to
satisfy applicable European standards (EN standards). Tools with double in-
sulation are marked by the international symbol of a double square. These
tools must not be grounded and a two-wire cable is sufficient to supply
them with power. Tools are shielded in accordance with EN 55014.
Use
The machine is designed for splitting, roughing and brushing metal and
stone materials without the use of water. For cutting stone, a cutting guide
is required.
The user himself is liable for any improper use.
Protective elements and their
assembly
The grinder may be used with mounted protective guard only!
Attention! Prior to handling the accessories, the power supply cable
has always to be disconnected from the power source socket.
Protective guard
Attention! The protective guard intended only and exclusively for
work with the grinding wheels is the integral part of the standard
angular grinder outfit. When cutting, the angular grinder has to be
equipped by the protective guard intended for work with the cutting
wheels; it can be purchased in the trade network under the order
No. 00 763 301 for dia. 125 mm. Failing to use the guard for cutting,
you run the increased risk of injury and in this case (non-use of the
special guard for cutting) the company Narex is not liable anyhow for
possible harm of health of the user or another person injured as the
consequence of breach of the safety rules.
