Protective guard

Attention! The protective guard intended only and ex-

clusively for work with the grinding wheels is the inte-

gral part of the standard angular grinder outfit.

When cutting, the angular grinder has to be equipped by the pro-

tective 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 in-

creased 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 conse-

quence 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 requested working position.

Note: The protective guard has been designed so that no tool may 

be needed for fixing the protective guard in the requested 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 col-

let (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 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 (14a) as well as 

the clamping surfaces of the grinding or cutting wheel. Place the 

bottom flange (11) (by the recess out) on the spindle (7). Place the 

grinding (12) or cutting wheel (13). The bottom flange recess (11) 

must be inserted precisely into the grinding wheel (12) or the cut-

ting wheel (13) hole. Then put the clamping nut (14a) on the spin-

dle (7) so that when fixing the grinding wheel (12), the clamping 

nut recess (15) must be faced towards the wheel and when fixing 

the cutting wheel (13), the clamping nut recess (15) must be di-

rected from the wheel!

Depress the lock spindle pin (3).

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!
