Work Instructions; Environmental Protection - Narex EV 16 K-2 Instrucciones De Uso

English
Apply the pressure required for work against the
handle only and not against the auxiliary handle (9).
Clamping a drill
Insert tool and tighten equally in all 3 holes with chuck key.
Switching on and off
By pressing the switch button (4a) the machine activates and re-
leasing the button stops it.
Permanent run
By pressing the switch button (4a) to the stop and simultaneous
pressing the latching pin (3) permanent run is achieved.
Repeated pressing the switch button (4a) and its release the per-
manent run is discontinued.
Speed control
By light and gradual pressing the controller button (4a) you will
achieve low speed and controlled continuous run-up.
By further gradual pressing the button the speed increases to the
pre-selected speed.
Electronic speed pre-selection
Using the pre-selection wheel (5) the required pre-selected speed
is set–even if the machine runs. The necessary speed depends
on the type of the material drilled, and a practical test is recom-
mended to verify it.
If the machine is loaded considerably, adjust the pre-selection
wheel (5) to the marginal position in the + direction (max speed
– control disconnected).
After a longer work at low speed leave the machine run idle for
3 minutes at maximum speed to cool the engine down.
Gear shifting
Use the speed lever (7) to adjust the 2nd speed gear:
1. Speed – lower speed gear – higher torque
2. Speed – higher speed gear – lower torque
In any speed gear you can adjust the final speed by means of the
electronic pre - selection. However, firstly select the mechanical
speed gear.
Changing the gears can be done at slowing the machine down or
in idle run but never when the machine is fully loaded. Once the
gear is changed, leave the machine start up slowly.
Change in rotation
Adjust the rotation direction switch (4b) to the right (left run) or to
the left (right run). The left run allows e.g. cutting the threads and
unscrewing of bolts or nuts.
Changing is blocked if the controller button is pressed. The rotation
direction has to be changed when the machine is idle.
WARNING! If the left run is used, the chuck has to be screwed
on very firmly.
Drilling and impact drilling (EVP 16 K-2)
Shift in or out the hammer by the hammer gear button (8). The
shifting can be done even when the machine runs.
Percussion drilling:
Pull the button (8) in the direction of the symbol - hammer.
Drilling:
Pull out the button (8) in the direction of the symbol - drill.
The impact drilling is recommended to be used in concrete, brick-
work and earthenware. Axial spindle backlash - to 2.5 mm. Radial
backlash measured on the pin clamped in the chuck within the
spacing range of 50 mm to 0.3 mm.
Removing the chuck with ring gear
Hold the spindle on the surface (12) using an open wrench (22 mm).
Insert the chuck hook (11) into a single opening on the chuck and
by turning left screw the chuck out. Release the firmly clamped
chuck by impacts of the hammer on the chuck hook (11).

Work instructions

Drill bits
For steel use perfect and sharpened drill bits made of good-quality
high - speed steel.
Drilling stands
For precise drilling on smaller parts, use of a drilling stand is rec-
ommended.
Clamping device
Clamp the worked pieces properly into the screw-type clamping
unit. Thus turning of the piece is avoided, as well as a potential ac-
cident.
Drilling in tiles
Shift the impact gear lever (8) to the drill-bit symbol. Once the up-
per layer is drilled through, shift the impact gear lever to the ham-
mer symbol.
Maintenance
‰
The vent holes (6) of the engine cover must not get plugged.
‰
After about 100 hours of operation the following works need
to be done:
- Check of the brushes length Brushes shorter than 5 mm must
be replaced with new ones.
‰ After about 200 hours of operation the following works need
to be done:
- Exchange of lubricating grease in the gearbox and bearings.
To keep the protection class the machine needs to be checked in
terms of safety, and therefore these works must be carried out in
an authorised electric workshop holding the relevant licence to
perform these kinds of activities.
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.

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.
