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.
5
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.
Additional safety rules
for demolition breakers
• Before breaking into walls, floors etc., ensure there are
no concealed power cables or pipes in the cavity.
• Always use the front handle, this gives you greater
control and ensures safe operation.
• Keep the cord clear of the accessory being used, do not
wrap the cord around your arm or wrist.
• Hold the tool by the insulated gripping surfaces when
performing an operation where the accessory may
contact hidden wiring or its own cord.
• Use thick cushioned gloves and limit the exposure time
by taking frequent breaks. Vibration caused by the
hammer action may be harmful to your hands and arms.
• When removing an accessory from the tool avoid contact
with skin and use proper protective gloves when grasping
the bit or accessory. Accessories may be hot after
prolonged use.
• Use hearing protection.
WARNING! Some dust created by power sanding, sawing,
grinding, drilling and other construction activities contain
chemicals known to cause cancer, birth defects or other
reproductive harm.
Some examples of these chemicals are:
• Lead from lead-based paints;
• Crystalline silica from bricks, cement and other masonry
products, and;
• Arsenic and chromium from chemically-treated timber.
The risk from such exposures vary depending on how
often you do this type of work. To reduce your exposure
6
to these chemicals; work in a well ventilated area, and
work with approved safety equipment, such as those dust
masks that are specifically designed to filter out microscopic
particles. Always wear eye protection and a dust mask
for dusty applications. Sanding particles can be absorbed
by your eyes and inhaled easily and may cause health
complications.
• Wear ear protectors. Exposure to noise can cause
hearing loss.
• Use auxiliary handle(s), if supplied with the tool. Loss of
control can cause personal injury.
• Hold power tool by insulated gripping surfaces, when
performing an operation where the cutting accessory may
contact hidden wiring or its own cord. Cutting accessory
contacting a “live” wire may make exposed metal parts
of the power tool “live” and could give the operator an
electric shock.
• Wear a hard hat (safety helmet), safety glasses and/or
face shield. Ordinary eye or sun glasses are NOT safety
glasses. It is also highly recommended that you wear a
dust mask and thickly padded gloves.
• Be sure the bit is secured in place before operation.
• Under normal operation, the tool is designed to produce
vibration. The screws can come loose easily, causing
a breakdown or accident. Check tightness of screws
carefully before operation.
• In cold weather or when the tool has not been used for a
long time, let the tool warm up for a while by operating it
under no load. This will loosen up the lubrication. Without
proper warm-up, hammering operation is difficult.
• Always be sure you have a firm footing. Be sure no one
is below when using the tool in high locations.
• Hold the tool firmly with both hands.
• Keep hands away from moving parts.
• Do not leave the tool running. Operate the tool only when
hand-held.
• Do not point the tool at any one in the area when
operating. The bit could fly out and injure someone
seriously.
• Do not touch the bit or parts close to the bit immediately
after operation; they may be extremely hot and could
burn your skin.
• Do not operate the tool at no-load unnecessarily.
• Some material contains chemicals which may be toxic.
Take caution to prevent dust inhalation and skin contact.
WARNING. We recommend the use of a residual current
device with a residual current rating of 30mA or less.
Wear goggles
Wear ear muffs
Wear a breathing mask

Unpacking
Due to modern mass production techniques, it is unlikely
that your 909 Power Tool is faulty or that a part is missing.
If you find anything wrong, do not operate the tool until the
parts have been replaced or the fault has been rectified.
Failure to do so could result in serious personal injury.
Fitting and removing accessories
1. Clean and grease the
accessory’s shank.
2. Pull out the bit lock pin (10)
and rotate it 180°.
3. Insert the shank of the accessory
into the chuck
. Ensure
the notch in the shank is
positioned upward as per
image shown on the right.
Should the notch be in the
incorrect position the shank
will not lock into position.
4. Lock the shank into the nose
of the tool by pulling out the bit
lock and rotating it 180°.
5. Pull the accessory to ensure
the shank is properly secured
into the nose of the tool prior to operation.
6. To remove the accessory, pull out the bit lock, rotate 180°
and pull the accessory from the nose of the tool.
Note: To avoid damage to the bit lock, only use round hex
shank bits. Damage caused to the bit lock by using incorrect
accessories will not be covered under warranty.
Auxiliary handle
1. Loosen the nut (7) anti
clockwise to loosen the collar,
rotate the handle to suit the
application.
2. Tighten the nut so the handle
is secure and will not slip.
Switching on and off
Connect the plug to the power
point.
Depress the ON/OFF switch (5)
which will start the unit.
Release the switch to stop the
unit.
For prolonged use pull the switch
on and depress the lock-on
button (6).

Operation
Always use the auxiliary handle
(4) and firmly hold the tool by
both auxiliary handle and switch
handle during operations. Turn
the tool on and apply slight
pressure on the tool so that the
tool will not bounce around,
uncontrolled. Pressing very hard
on the tool will not increase the
efficiency.
Maintenance
• The grease in the gearbox
will require replenishment
after approximately 50 hours
accumulated use. After this
time add approximately 30
grams of grease into the
gearbox. First remove the
gear box cover plate (3)
and washer from the tool
by removing the 4 retaining
screws using an allen key
then remove the metal cover
and washer. Add the grease
through this hole. Ensure the
washer and gear box cover
plate are put back into position
and secured with the 4 allen
key screws prior to operation.
• After each use, blow air
through the tool housing to
ensure it is free from all dust
particles that may build up.
Build up of dust particles may
cause the tool to overheat
and fail.
• If the enclosure of the tool requires cleaning do not use
solvents but a moist soft cloth only. Never let any liquid
get inside the tool. Never immerse any part of the tool
into a liquid.
• When the carbon brushes wear out the tool will spark
and/or stop. The brushes are a wearing component of the
tool and should be replaced prior to the carbon wearing
out fully. Brushes will wear out after many uses but before
they do take the tool to an authorised service agent for
quick and low cost replacement. Always replace both
brushes at the same time.
Note: 909 will not be responsible for any damage or injuries
caused by the repair of the tool by an unauthorised person
or by mishandling of the tool.
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 will usually be
sufficient to ensure acceptable internal cleanliness.
5. Wear eye protection when carrying out cleaning.
CAUTION. 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.
