Tips for practice

Do not drill on the places where hidden el. distribution lines, gas or wa-

ter 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 diam-

eter.

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 di-

rectly 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 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

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 tempera-

ture changes.

Environmental protection

Power tools, accessories and packaging should be sorted for environ-

mental-friendly recycling.

Do not dispose of power tools into household waste!
According to the European Directive 2002/96/EC on waste electrical and
