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
