ing, do not allow any interference of the wire wheel or 

brush with the guard.

 Wire wheel or brush may expand 

in diameter due to work load and centrifugal forces.

Information about noise level and 

vibrations

The values have been measured in conformity with EN 60745.
Acoustic pressure level L

pA

 = 90.2 dB (A).

Acoustic power level L

wA

 = 101.2 dB (A).

In accuracy of measurements K = 2 dB (A).

ATTENTION! Noise is generated during work!
Use ear protection!

The weighted value of vibrations affecting hands and arms

The emission values specified (vibration, noise) were meas-

ured in accordance with the test conditions stipulated in 

EN 60745 and are intended for machine comparisons. They are 

also used for making preliminary estimates regarding vibra-

tion and noise loads during operation.
The emission values specified refer to the main applications 

for which the power tool is used. If the electric power tool is 

used for other applications, with other tools or is not main-

tained sufficiently prior to operation, however, the vibration 

and noise load may be higher when the tool is used.
Take into account any machine idling times and downtimes 

to estimate these values more accurately for a specified time 

period. This may significantly reduce the load during the ma-

chine operating period.

Double insulation

To ensure maximum safety of the user, our tools are designed 

and built to satisfy applicable European standards (EN stand-

ards). Tools with double insulation are marked by the inter-

national 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 cut-

ting 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 grind‑

er 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.
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 re-

quested working position.
Note: The protective guard has been designed so that no tool 

may be needed for fixing the protective guard in the request-

ed working position.

Attention! For safety reasons the clamping bolt (10) has 

been tightened 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 

clamping bolt (10) use the hexagonal wrench dia. 4 mm (18) 

and check the torque 3.5 Nm.

Additional handle SOFTGRIP

The additional handle (17) can be screwed from the left or 

right gearbox (5) side or from the top gearbox (5) part. Thanks 

to the special design vibrations are reduced by the additional 

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!

Mounting with the standard clamping nut

Clean the bottom flange (11) and the clamping nut (13) as 

well as the clamping surfaces of the grinding or cutting wheel. 

Place the bottom flange (11) (by the recess out) on the spin-

dle (7). Place the grinding or cutting wheel (12). The bottom 

flange recess (11) must be inserted precisely into the grind-

ing wheel or the cutting wheel hole. Then put the clamping 

nut (13) on the spindle (7) so that when fixing the grinding 

wheel, the clamping nut recess (15) must be faced towards 

the wheel and when fixing the cutting wheel, 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 (13) firmly, using the 

wrench (16).

Attention! Prior to starting the grinder, verify that 

the wheel does not rotate freely between the bot‑

tom flange (11) and the clamping nut (13).

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 with-

out the quick-clamping nut, with the sole difference, that after 

spindle locking the quick-clamping nut (14) may be tightened 

by hand only.

Attention! Do not tighten the quick‑clamping nut 

without the wheel not to damage its mechanism!

Attention! Prior to starting the grinder, verify that 

the wheel does not rotate freely between the bot‑

tom flange (11) and the clamping nut (14).
