Maintenance And Service; Environmental Protection - Narex EKV 20 E Instrucciones De Uso

English
Direction switch
Use the direction switch (7) only if the hammer drill is at rest. Grip
the speed switch (7) from both sides.
Rotation to the right: Move the speed switch (7) to „R".
Rotation to the left: Move the speed switch (7) to „L".
Important! Swivel the speed switch (7) as far as the stop on
the motor guard, until you can hear a click. If the speed switch
is in the intermediate position between „R" and „L", the ham-
mer drill cannot be started.
Inserting and removing bits
Drilling and chiseling bits are inserted to and removed from the
chuck head (1) without a key.
Inserting bits
Before any interference to the tool, disconnect the supply cable
first.
Clean the shank of the bit and grease it slightly.
When setting the tool into the clamping head, pull the fixing
sleeve (2) towards the body of the device and swivel the tool slowly
until it is is locked (seated firmly).
Be careful not to damage the cover protecting the chuck head
against dust penetration (11). Replace damaged dust cover
immediately with a new one!
Removing bits
Push the locking sleeve (3) down towards the body of the hammer
and remove the bit.
Chuck and adapter (accessories)
Adapter (9) and chuck (10) has to be used for drilling and screwing
into metal, wood and plastics with the drills having the cylindrical
shank.
Chuck fixing on the adapter
The adapter (9) is equipped on the one side by the SDS-Plus shank
and on the other side by the thread ½"x20 UNF for the chuck.
Screw the chuck (10) carefully onto the thread.
Fixing chuck with adapter
Disconnect the feeding cable from the socket before any interven-
tion into the device.
Clean the adapter shank and smear it easily.
When setting the chuck with adapter into the clamping head,
pull the fixing sleeve (2) towards your body and swivel the chuck
slowly until the adapter shank is locked (seated firmly). Then check,
whether the chuck with the adapter is fixed and will not fall out of
the fixing head.
Removal of the chuck with adapter
Pull the fixing sleeve (2) towards your body a and remove the
chuck with the adapter.
Tips for practice
Do not drill on the places where hidden el. distribution lines, gas or
water pipes could be laid. At first check the place where you intend
to drill, using for instance the metal detector.
Use only perfectly ground drills for drilling into metal, use ade-
quate drills with tungsten carbide drills for drilling into stone and
concrete.
Adapt speed to the material you drill into and to the used drill di-
ameter.
Impact drilling
Use protective goggles and ear protectors.
Do not apply a very high force on the hammer drill. Its perfor-
mance will not be increased anyhow.
Always work with the extension handle (8).
Prior to starting the device, check whether the function switch (6)
is set to the requested position.

Drilling into tiles
Drill the tile at firs slowly without impact. After it is drilled partially,
switch to impact drilling.
Screwing
Screwing bits can be clamped into the chuck (10) (accessories) or
directly into the adapter (9) (accessories).

Maintenance and service

Attention! Risk of el. shock. Prior to start any opera-
tion, pull the plug out of the socket!
Keep the ventilating apertures (3) clean.
Clean plastic parts accessible from outside regularly with a piece of
cloth without any cleaning detergents.
After using the drill over a period of long time in demanding con-
ditions, it is advisable to bring the appliance to a Narex authorized
service centre for check up and thorough cleaning.
The appliance is equipped with self-detachable carbons. If the
carbons are worn down, the motor automatically switches off. This
prevents the rotor from further damage. The carbons may be re-
placed only by an authorized service centre.
Approximately every 100 work hours it is also necessary to bring
the hammer for a regular period maintenance, which should guar-
antee steady and good work output and operating life.
Each regular period maintenance check consists of these tasks:
• Cleaning of motor housing, removal of deposits, dirt and dust
from the housing.
• Cleaning of chucking nub.
• Checking of piston rings wear and tear.
• Checking the carbons wear and tear.
• Replacement of grease fillings.
• Crosschecking of safety clutch function.
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".
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
environmental-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.
