Chiseling
To start chiseling switch the change over switch (7) to
Rotation regulation
You can continuously change rotations with the switch (6). Push the
switch slightly and the hammer will start rotating slowly. The stroger
you push at the switch, the faster the rotation.
Switching the direction of rotation
Use the switch for change of rotating direction (9) only when the ham-
mer is at stand still.
Hold the switch (9) from both sides.
To set direction of rotations to the right (9), switch to "R" position.
To set direction of rotations to the left (9), switch to "L" position.
Important! Turn the rotation switch (9) all the way to arrester at
the motor casing, until you feel it snaps.
If the position of rotation switch is between "R" and "L", the ham-
mer will not switch on.
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 inserting the bit into the chuck head turn the bit slowly until it
sets in. Check if it is properly fixed in the chuck head, so it will not fall
out.
Be careful not to damage the cover protecting the chuck head
against dust penetration (2).
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.
Setting the chiseling bit
Switch the change over switch (7) to [rotation off] position. Then you
can turn the chiseling bit manually and set it to any required working
position.
Switch the rotation switch (7) back to
automatically clicks in when work, that is chiseling, creates radial pres-
sure to it.
Attention: In order to be able to switch the rotation switch (7) you
must first push the safety (8).
Quick change chuck (accessory)
The hammer is supplied with a quick-change chuck for drilling in wood,
metal and plastic materials with drills with a cylindrical shank (max.
clamping diameter 13 mm). The chuck is mounted at holding spindle
of the hammer (12).
Before any interference to the tool, disconnect the supply cable first.
Dismounting the chuck
Push the locking sleeve (4) up from the body of the hammer and loosen
the chuck from holding spindle.
Mounting the chuck
Clean the holding spindle first.
Push the locking sleeve (4) up from the body of the hammer and mount
the required chuck (11) or (13) to the holding spindle. Turn it slightly
when doing so. Then let the locking sleeve drop and check if the chuck
holds firmly in.

Practical hints

Do not drill in places with possibility of concealed electric wiring, gas
and water piping. Check the spot, where you want to drill first, for exam-
ple using a metal detector.
To drill in metal use only perfectly sharp drill bits, to drill in stone and
concrete use only carbide bits intended for stone drilling.
Adapt rotation to drilled material and to the diameter of used drill bit.
Percussion drilling and chiseling
Use protective goggles and ear protectors
Do not push the drilling hammer with an excessive force. This will not
result in higher output.
When chiseling, the best results can be obtained if you cut off the mate-
rial in small pieces.
When chiseling, always wear protective goggles and use the side handle
(10). After switching the hammer on, check if the change over switch (7)
is secured in position.
Drilling through tiles
First, slowly drill a hole into the tile. After drilling through, switch to
percussion drilling.
Screwing
Screwing bits may be inserted into the quick-change chuck (11) (acces-
sory).
Maintenance
Before commencing any maintenance, disconnect the hammer from
power outlet.
Keep the ventilating apertures 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 conditions,
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 replaced only by an au-
thorized service centre.
Approximately every 100 work hours it is also necessary to bring the
hammer for a regular period maintenance, which should guarantee
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.
Storage
The packed device can be stored in a dry unheated store room where
the temperature does not drop below -5°C.
Store the unpacked device in a dry store room where the temperature
does not drop below +5°C and where abrupt temperature changes are
prevented.

Environmental protection

El. tools, accessories and packaging should be collected for subsequent
recovery, recycling and environmentally sound disposal.
For EU countries only:
Do not dispose the el. tools as the home waste!
In conformity with the European Directive 2002/96/EC on waste electri-
cal and electronic equipment and its implementation in national legisla-
tions the unusable dismantled el. tools should be collected for subse-
quent recovery, recycling and environmentally sound disposal.
