10.2 Continuous operation

Push the safety lock-off lever  [2] forwards to release the On/Off 

switch lever [1]. At the same time, press the on-off switch lever [1] 

and push the safety lock-off lever [2] forwards. To turn off continu-

ous operation, press and release the on-off switch [1] again.

10.3 Power Plug

WARNING!

 Risk of injury if the power tool is used with 

incorrect mains power supply.

The power tool may only be used with single-phase alternating 

current with rated voltage of 220–240 V / 50–60 Hz. The power tool 

has double insulation against injury by electric current in line with 

standard EN 60745 and features integrated interference elimina-

tion in line with standard EN 55014.
Before turning the tool on, check that the information on the pro-

duction plate matches the real voltage in the socket.
The power cable can be extended if needed as follows:
– 20 m length, conductor cross section: 3 × 1.5 mm

2

– 50 m length, conductor cross section: 3 × 2.5 mm

2

Only use extension cables designed for outdoor use and bearing 

the appropriate markings.

Operation with an Electric Generator (EG) with a Combustion 

Engine

The manufacturer of the tool cannot guarantee faultless operation 

with all EGs.
The tool can be used with an EG if the following conditions are met:

»

  The output voltage of the EG must always be in 230 VAC ±10 % 

range. The EG should be fitted with automatic voltage regula-

tion (AVR). Without AVR, the tool may not work correctly and 

may even get damaged!

»

  The power of the EG must be at least 2.5 times higher than the 

input power of the tool.

»

  Using the power tool with an EG with insufficient power may 

result in speed fluctuations and reduced output of the tool.

11 Motor electronics

Increases productivity, service life of the grinding machine, com-

fort at work, quality and safety of labour. Its features are as follows:

11.1 Restart protection

If power supply is interrupted at work (disconnection of the supply 

cable plug, tripping, cutout, etc.) and the switch remains arrested 

in the ON position, after resumption of power supply the machine 

will not be restarted automatically. To start the grinding machine, 

the switch has to be switched OFF at first and ON afterwards.

11.2 Smooth starting

After the grinding machine is switched ON, the control electron-

ics guarantees smooth start and running up to the working speed 

without unnecessary shocks. This way service life of the grinding 

machine may be extended and wear of the gear reduced.

12 Grinding and cutting discs

Check that the label on the disc shows the permissible peripheral 

speed or permissible revolution speed.
If the permissible revolution speed is given on the disc, it must not 

be lower than the highest no-load speed of the grinder.
Discs with a  permissible peripheral speed of 80 m/s and higher 

may be used.
Test new cutting discs by letting them run for about one minute 

with no load.
Unbalanced or vibrating discs should not be used and should be 

discarded.
Protect grinding discs from shock, impact and lubricants.
If the grinding and cutting wheels are worn down to the mark on 

the wheel guard (see the arrow sign), they should be replaced with 

new ones. This maintains the optimum grinding and cutting per-

formance of the machine (peripheral speed of the grinding and 

cutting wheels).

13 Maintenance and service

Attention! Risk of el. shock. Prior to start any opera-

tion, pull the plug out of the socket!

Vent holes [3] of the motor guard may not be covered.
Cable replacement must be carried out by a specialized service sta-

tion authorized correspondingly.

After ca 150 hours of operation the following activities and 

works have to be carried out:

Check of brush length. The brushes shorter than 5 mm have to be 

replaced for new ones.
The grinder will be stopped automatically if the brushes are worn. 

The grinder is sent to the service station for maintenance.
Grease replacement in gearbox and bearings.

Attention! With respect to protection from el. shock 

and preservation of the class of protection, all mainte-

nance and service operations requesting jig saw case 

removal must be performed by the authorized service centre 

only!

14 Accessories

The accessories recommended for use with this device are availa-

ble commercially in the shops with hand el. tools.

15 Storage

Packed appliance may be stored in dry, unheated storage place 

with temperature not lower than -5 °C.
Unpacked appliance should be stored only in dry storage place 

with temperature not lower than +5 °C with exclusion of all sudden 

temperature changes.

16 Environmental protection

Power tools, accessories and packaging should be sorted for envi-

ronmental-friendly recy.

Only for EU countries:

Do not dispose of power tools into household waste!
According to the European Directive 2002/96/EC on waste electri-

cal and electronic equipment and its incorporation into national 

law, power tools that are no longer suitable for must be separate-

ly collected and sent for recovery in an environmental-friendly 

manner.

17 Warranty

Our equipment is under warranty for at least 12 months with re-

gard to material or production faults in accordance with national 

legislation. In the EU countries, the warranty period for exclusively 

private use is 24 months (an invoice or delivery note is required as 

proof of purchase).
Damage resulting from, in particular, normal wear and tear, over-

loading, improper handling, or caused by the user or other dam-

age caused by not following the operating instructions, or any 

fault acknowledged at the time of purchase, is not covered by the 

warranty.
Complaints will only be acknowledged if the equipment has not 

been dismantled before being sent back to the suppliers or to an 

authorised NAREX customer support workshop. Store the operat-

ing instructions, safety notes, spare parts list and proof of purchase 

in a  safe place. In addition, the manufacturer’s current warranty 

conditions apply.
