in the trade network under the order No. 00 763 302 for
dia. 150 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.
Release the locking screw (7). Attach the protection guard (8)
onto the spindle collar (6). Adjust the position of the protection
guard (8) to the application. Tighten the locking screw (7). For
safety reasons the bolt has to be tightened with 4+0.5 Nm torque.
Additional handle SOFTGRIP
Special construction regulates the vibrations with auxiliary han-
dle (5). Auxiliary handle can be screwed from the left or right side
of gearbox (4). Some operations may require the handle screwed
to the top of gearbox.
Autobalancer (self-balancing assembly)
Autobalancer (18) is pressed on the grinder spindle by the manu-
facturing 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 (18) replaces the bottom flange.
Grinding or cutting wheel fixing
Attention! Prior to handling the accessories, the pow-
er supply cable has always to be disconnected from
the power source socket!
Mounting with the standard clamping nut
Clean the bottom flange (11) and the clamping nut (9) as well as
the clamping surfaces of the grinding or cutting wheel. Place the
bottom flange (11) (by the recess out) on the spindle (12). Place the
grinding (10) or cutting wheel (17). The bottom flange recess (11)
must be inserted precisely into the grinding wheel (10) or the cut-
ting wheel (17) hole. Then put the clamping nut (9) on the spin-
dle (12) so that when fixing the grinding wheel (10), the clamping
nut recess (15) must be faced towards the wheel and when fixing
the cutting wheel (17), the clamping nut recess (15) must be di-
rected from the wheel!
Depress the lock spindle pin (13).
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 (13) is engaged.
Tighten the clamping nut (9) firmly, using the wrench (14). Prior to
start the grinder verify that the wheel does not rotate freely.
Attention! Prior to starting the grinder, verify that the wheel
does not rotate freely between the bottom flange/the auto-
balancer and the clamping nut.

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 insulation 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 met-
al 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 pow-
er supply cable has always to be disconnected from
the power source socket!
Protective guard
Attention! The protective guard intended only and exclu-
sively for work with the grinding wheels is the integral part
of the standard angular grinder outfit. When cutting, the an-
gular grinder has to be equipped by the protective guard in-
tended for work with the cutting wheels; it can be purchased
