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 adequate drills

with tungsten carbide drills for drilling into stone and concrete.
Adapt speed to the material you drill into and to the used drill diameter.

Impact drilling

Use protective goggles and ear protectors.
Do not apply a very high force on the hammer drill. Its performance 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

Before commencing any maintenance, disconnect the hammer from power

outlet.
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 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 authorized

service centre.
Approximately every 100 work hours it is also necessary to bring the ham-

mer 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.

Unpacked appliance should be stored only in dry storage place with tem-

perature not lower than +5°C with exclusion of all sudden temperature

changes.
