Your 909 power tool has many features that will make

your job faster and easier. Safety, performance, and

dependability have been given top priority in the

development of this tool, making it easy to maintain

and operate.

Environmental protection

Recycle unwanted materials instead

of disposing of them as waste. All tools,

hoses and packaging should be sorted,

taken to the local recycling centre and

disposed of in an environmentally safe way.

General safety rules

WARNING.

Read all safety warnings and all instructions.

Failure to follow the warnings and instructions may result in

electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

The term “power tool” in the warnings refers to your mains-

operated (corded) power tool or battery-operated (cordless)

power tool.

1) Work area safety
a) Keep work area clean and well lit.

Cluttered or dark

areas invite accidents.

b) Do not operate power tools in explosive

atmospheres,

such as in the presence of flammable

liquids, gases or dust. Power tools create sparks which

may ignite the dust or fumes.

c) Keep children and bystanders away while operating a

power tool.

Distractions can cause you to lose control.

2) Electrical safety
a) Power tool plugs must match the outlet. Never modify

the plug in any way.

Do not use any adapter plugs with

earthed (grounded) power tools. Unmodified plugs and

matching outlets will reduce risk of electric shock.

b) Avoid body contact with earthed or grounded

surfaces, such as pipes, radiators, ranges and

refrigerators.

There is an increased risk of electric

shock if your body is earthed or grounded.

c) Do not expose power tools to rain or wet conditions.

Water entering a power tool will increase the risk of

electric shock.

d) Do not abuse the cord. Never use the cord for

carrying, pulling or unplugging the power tool.

Keep cord away from heat, oil, sharp edges or

moving parts.

Damaged or entangled cords increase

the risk of electric shock.

e) When operating a power tool outdoors, use an

extension cord suitable for outdoor use.

Use of a cord

suitable for outdoor use reduces the risk of electric shock.

f) To reduce the risk of electric shock, the manufacturer

recommends the use of a residual current device

with a rated residual current of 30mA or less at

all times.

3) Personal safety
a) Stay alert, watch what you are doing and use

common sense when operating a power tool. Do not

use a power tool while you are tired or under the

influence of drugs, alcohol or medication.

A moment

of inattention while operating power tools may result in

serious personal injury.

b) Use personal protective equipment. Always wear eye

protection.

Protective equipment such as dust mask,

non-skid safety shoes, hard hat, or hearing protection used

for appropriate conditions will reduce personal injuries.

c) Prevent unintentional starting. Ensure the switch

is in the off-position before connecting to power

source and/or battery pack, picking up or carrying

the tool.

Carrying power tools with your finger on the

switch or energising power tools that have the switch

on invites accidents.

d) Remove any adjusting key or wrench before

turning the power tool on.

A wrench or a key left

attached to a rotating part of the power tool may result

in personal injury.

e) Do not overreach. Keep proper footing and balance

at all times.

This enables better control of the power tool

in unexpected situations.

f ) Dress properly. Do not wear loose clothing or

jewellery. Keep your hair, clothing and gloves away

from moving parts.

Loose clothes, jewellery or long hair

can be caught in moving parts.

g) If devices are provided for the connection of dust

extraction and collection facilities, ensure these are

connected and properly used.

Use of dust collection

can reduce dust-related hazards.

4) Power tool use and care
a) Do not force the power tool. Use the correct power

tool for your application.

The correct power tool will

do the job better and safer at the rate for which it was

designed.

b) Do not use the power tool if the switch does not turn

it on and off.

Any power tool that cannot be controlled

with the switch is dangerous and must be repaired.

c) Disconnect the plug from the power source and/or

the battery pack from the power tool before making

any adjustments, changing accessories, or storing

power tools.

Such preventive safety measures reduce

the risk of starting the power tool accidentally.

d) Store idle power tools out of the reach of children

and do not allow persons unfamiliar with the power

tool or these instructions to operate the power tool.

Power tools are dangerous in the hands of untrained users.

e) Maintain power tools. Check for misalignment or

binding of moving parts, breakage of parts and any

other condition that may affect the power tool’s

operation. If damaged, have the power tool repaired

before use.

Many accidents are caused by poorly

maintained power tools.

f ) Keep cutting tools sharp and clean.

Properly

maintained cutting tools with sharp cutting edges are

less likely to bind and are easier to control.

g) Use the power tool, accessories and tool bits etc.

in accordance with these instructions, taking into

account the working conditions and the work to be

performed.

Use of the power tool for operations different

from those intended could result in a hazardous situation.

h) This appliance is not intended for use by persons

(including children) with reduced physical, sensory

or mental capabilities, or lack of experience and

knowledge,

unless they have been given supervision or

instruction concerning use of the appliance by a person

responsible for their safety.

i) Children should be supervised to ensure that they do

not play with the appliance.

5) Service
a) Have your power tool serviced by a qualified repair

person using only identical replacement parts.

This

will ensure that the safety of the power tool is maintained.

Inserting and removing bits

CAUTION.

Always ensure that the drill is switched off

and the plug is removed from the power point before

making any adjustments.
This drill has a keyless chuck, which means that a chuck

key is not needed to secure a bit in the drill.
1. Open the chuck by holding the

rear section of the chuck firm

and rotating the front section

in a anti-clockwise direction,

sufficiently enough to allow the

drill bit required to fully enter

the jaws of the chuck.

2. Ensure the drill bit is

fully inserted.

3. Holding the rear section of the

chuck firmly, rotate the front

section of the chuck clock wise

until the jaws tighten on the

drill bit. The front section of the

chuck needs to be tightened

firmly to ensure the drill bit is

held securely.

Turn the gear selector to Position “2”.

Note.

Do not change gears when the drill motor is turning.

If you are having trouble changing gears, make sure that

the gear selector is either completely in Position 1 or

completely in Position 2 as you rotate the chuck by hand.

Chuck replacement

Always wear eye protection.

Chuck removal

The chucks of reversible drills are always fixed by a screw

with left-hand thread. The screw, which is located in the

centre of the chuck, must be removed before the chuck can

be removed.
1. Tighten the chuck around the shorter end of a hex key

(not supplied) of 1/4” or greater size. Using a wooden

mallet or similar object, strike the longer end in the

clockwise direction. This will loosen the screw inside

the chuck.

2. Open chuck jaws fully.
3. Insert a screwdriver into front of chuck between jaws to

engage screw head. Remove screw by turning clockwise.

4. Place a hex key in chuck and

tighten. Using a wooden mallet or

similar object, strike key sharply

in the counter clockwise direction.

This will loosen the chuck so that

it can be unscrewed by hand.

Chuck installation

1. Screw the chuck on by hand as far as it will go and insert

screw (LH thread).

2. Tighten the chuck

around the shorter end

of a 1/4” or large hex

key (not supplied) strike

the longer end in the

clockwise direction with

a wooden mallet.

3. Remove the hex key

and open the jaws fully. Tighten the screw in the centre of

the chuck firmly.

Hints for use

Note.

When drilling into masonry the drilling rate is fast

and burnout of the tip will occur if the drill bit is not

constantly cleared.

•

Use only correctly sharpened drill bits, which are suitable

for the material being drilled.

•

To drill hard materials, firm pressure is required on the

power tool. However, excessive pressure does not

improve performance and places unnecessary pressure

on the tool and its bit.

•

When screw driving always use a pilot hole and set the

speed dial to low. Press firmly on the screw head and pull

the trigger gradually increasing the speed. It is always

wiser to test the screw driving on a scrap piece of the

same material you are using.

•

Larger diameter holes in hard wood, steel and concrete

have to be drilled at slower speeds. However, the motor

must not be struggling with the operation. If the motor is

struggling

DO NOT

continue working, pull the drill clear of

the workpiece and run it on fast speed for a minute or so

allowing the motor time to cool down before you attempt

a little more of the work. If the job is too hard for the drill

do not continue otherwise permanent damage to the

motor will occur.

•

Wire brushing or sanding should be carried out

on the highest speed.

•

Concrete drilling should be carried out on the

highest speed.

DO NOT

overload motor when drilling concrete.

DO NOT

use too much pressure as the hammer action

relies on the drill bit being able to move back and forward in

the hole being drilled.
Always clear the flutes of the drill bit by removing it from the

hole regularly.

Wood drilling

•

For maximum performance, use high speed steel bits for

wood drilling.

•

Move drilling/hammer mode selector to drilling mode .

•

Secure the workpiece to prevent it from turning

when drilling.

•

Begin drilling at a very low speed to prevent the bit from

slipping off the starting point. Increase the speed as the

drill bit bites into the material.

•

When drilling through holes, place a block of wood behind

the workpiece to prevent ragged or splintered edges on

the back side of the hole.

•

Do not lock the trigger in the ‘on’ position when the drill

may need to be stopped suddenly.

Metal drilling

•

For maximum performance, use high speed steel bits for

metal or steel drilling.

•

Move drilling/hammer mode selector to drilling mode .

•

Use a centre punch to mark the hole location on

the workpiece.

•

Begin drilling at a very low speed to prevent the bit from

slipping off the starting point.

•

Maintain a speed and pressure which allows cutting

without overheating the bit. Applying too much pressure

will:

  –   Overheat the drill
  –   Wear the bearings
  –   Bend or burn bits
  –   Produce off-centre or irregular shaped holes

•

When drilling large holes in metal it is recommended to

drill with a small bit at first, then finish with a larger bit.

Also, lubricate the bit with oil to improve drilling action

and increase bit life.

Masonry drilling

•

For maximum performance use tungsten carbide-tipped

masonry impact bits when drilling holes in brick, tile,

concrete, etc.

•

Move drilling/hammer mode selector to hammer mode .

•

Apply light pressure and medium speed for best results

in brick.

•

Apply additional pressure and high speed for hard

materials such as concrete.

•

When drilling in tile, practice on a scrap piece to determine

the best speed and pressure.

Cleaning

1. Keep your machine and its cord clean. The outside of the

machine can be cleaned using a damp soft cloth with a

mild detergent if required.

2. Some maintenance products and solvents may damage

the plastic parts; these include products containing

benzene, trichloroethylene, chloride and ammonia.

3. Excessive sparking generally indicates the presence of

dirt in the motor or abnormal wear on the carbon brushes.

4. Take special care to keep the ventilation inlets/outlets free

from obstruction; cleaning with a soft brush followed by

a compressed air jet will usually be sufficient to ensure

acceptable internal cleanliness.

5. Wear eye protection when carrying out cleaning.

Note

. Do not use cleaning agents to clean the plastic parts

of the drill.

Power cord maintenance

If the supply cord needs replacing, the task must be

carried out by the manufacturer, the manufacturer’s agent,

or an authorised service centre in order to avoid

a safety hazard.
