Environmental Protection - Narex ESR 20-5 Instrucciones De Uso

English
The required time of tightening may be estimated according
to the following scheme:
Based on the type of tightened parts, each combination of materi-
als must be tested separately. The effect of impact action exceed-
ing 10 seconds has no influence on the increase of the tightening
torque.
Screws of smaller sizes may be tightened at soft joint only,
whereas the tightening time may be even shorter than 1 sec-
ond. The impact action time should not exceed 2–3 seconds
in these cases.
While loosening screw joints (rusty screws etc.) even the max.
impact action time (10 seconds) may not be sufficient enough. In
such a case the impact mechanism should be allowed to act on and
off at cycles of about 10 seconds of impact action/ 10 seconds of
idle run to let the machine cool down.
Maintenance and service
Attention! Risk of el. shock. Prior to start any opera-
tion, pull the plug out of the socket!
‰ Air vents (4) shall not be clogged.
‰ Cord replacement may be only carried out in professional elec-
trical workshops by authorized and skilled personnel.
After about 200 operating hours the following works must be
performed:
‰ Check of brush length. Brushes shorter than 5 mm must be
replaced.
‰ Replacement of lubricant grease 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!
The current list of authorized service centres can be found at our
website www.narex.cz, section "Service Centres".
Accessories
The accessories recommended for use with this device are avail-
able commercially in the shops with hand el. tools.

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.

Environmental protection

Power tools, accessories and packaging should be sorted for envi-
ronmental-friendly recycling.
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 separately
collected and sent for recovery in an environmental-friendly man-
ner.
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.
Information about noise level and
vibrations
The values were measured in accordance with EN 60745.
Sound pressure level L = 97 dB (A).
pA
Sound power level L = 108 dB (A).
wA
Inaccuracy of measuring K = 1 dB (A)
WARNING! The use of the tool generates noise.
Use a suitable hearing protection!
The value of vibrations (sum of vectors in three directions) deter-
mined pursuant to EN 60745 a
Inaccuracy of measuring K = 4.4 m/s
The emission values specified (vibration, noise) were measured 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 vibration 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 maintained sufficient-
ly 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 machine operat-
ing period.
