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

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.
