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! Risk of el. shock. Prior to start any operation, pull
the plug out of the 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. 00 763 300 for dia. 115 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.
Put the protective guard (7a; 7b) on the clamping collet (5). The guide
lugs (8) must be inserted into the grooves on the clamping collet. Set the
protective guard (7a; 7b) to the requested working position.

Note: The protective guard has been designed so that no tool may be need-
ed for fixing the protective guard in the requested working position.
Attention! For safety reasons the clamping bolt (9) 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 (5), 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 clamping bolt (9) use the
hexagonal wrench dia. 4 mm (17) and check the torque 3.5 Nm.
Additional handle SOFTGRIP
The additional handle (16) can be screwed from the left or right gearbox (4)
side or from the top gearbox (4) part.
Thanks to the special design vibrations are reduced by the additional han-
dle (16).
Grinding or cutting wheel fixing
Attention! Risk of el. shock. Prior to start any operation, pull
the plug out of the socket!
Clean the bottom flange (10) and the clamping nut (13) as well as the
clamping surfaces of the grinding or cutting wheel. Place the bottom
flange (10) (by the recess out) on the spindle (6). Place the grinding (11)
or cutting wheel (12). The bottom flange recess (13) must be inserted pre-
cisely into the grinding wheel (11) or the cutting wheel (12) hole. Then put
the clamping nut (13) on the spindle (6) so that when fixing the grinding
wheel (11), the clamping nut recess (14) must be faced towards the wheel
and when fixing the cutting wheel (12), the clamping nut recess (14) 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 (13) firmly, using the wrench (15).
Attention! Prior to starting the grinder, verify that the wheel
does not rotate freely between the bottom flange (10) and the
clamping nut (13).
Putting into operation and control
Check whether the data on the rating plate match with the real pow-
er supply voltage. The tool intended for 230 V may be also connected to
220/240 V.
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 po-
sition.
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
in the ON position, then by moderate depressing the rear switch button
part (1), the switch will be released and returned to the initial position, i.e.
the machine will be switched off.
