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.
00 763 304 for ø 230 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 pos-
sible harm of health of the user or another person injured as the con-
sequence of breach of the safety rules.

Loosen the fixing lever (11). Put the protective guard (9a; 9b) on the clamp-
ing collet (6). The guide lug (10) must be inserted into the groove on the
clamping collet. Set the protective guard (9a; 9b) to the requested working
position and fix the collet, using the fixing lever (11). For safety reasons the
clamping bolt (12) must be tightened firmly by the torque 3+0,5 Nm.
Additional handle
Thanks to the special design „ VIBRASTOP" vibrations are reduced by the ad-
ditional handle (20). the additional handle can be screwed from the left or
right gearbox (5) side.
Autobalancer (self-balancing assembly) –
– EBU 23-26 CA
Autobalancer (8) is pressed on the grinder spindle by the manufacturing
plant and other angular grinders cannot be equipped by the Autobalancer
additionally. By its design Autobalancer reduces the vibrations generated
as the consequence of wheel disbalance, thus protecting the operator from
their harmful impact effectively.
Note: Autobalancer (8) replaces the bottom flange (13).
Adjustable main handle
By rotating the main handle (21), the design of which enables to swivel the
main handle in the longitudinal machine axis to three positions (0° – initial
position; +90° and -90°), the operator can take comfortable position for
work enabling permanent control of grinder controllers.
To set the main handle (21) to the requested position, the unlock but-
ton (22) has to be depressed and then the handle can be swiveled in the
longitudinal grinder axis in one of three available positions. After automatic
unlock button click the handle is fixed firmly in the chosen position.
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.
Mounting with the standard clamping nut
Clean the bottom flange (13) and the clamping nut (16) as well as the
clamping surfaces of the grinding or cutting wheel. Place the bottom
flange (13) (by the recess out) on the spindle (7). Place the grinding (14) or
cutting wheel (15). The bottom flange recess (16) must be inserted precisely
into the grinding wheel (14) or the cutting wheel (15) hole. Then put the
clamping nut (16) on the spindle (7) so that when fixing the grinding wheel
(14), the clamping nut recess (19) must be faced towards the wheel and
when fixing the cutting wheel (15), the clamping nut recess (19) must be
directed from the wheel!
Depress the lock spindle pin (4).
Attention! Use the lock spindle pin only if the spindle is at rest and the
grinder is de-energized.
Swivel the wheel /spindle, until the lock spindle pin (4) is engaged. Tighten
the clamping nut (16) firmly, using the wrench (17). Prior to start the grind-
er verify that the wheel does not rotate freely.
Mounting with quick-clamping nut
The quick-clamping nut must be tightened or loosened by hand only (never
use any additional tool!). Mounting of the grinding or cutting wheel is the
same like for the grinder without the quick-clamping nut, with the sole
difference, that after spindle locking the quick-clamping nut (18) may be
tightened by hand only.
