Congratulations on purchasing an Ozito Demolition Breaker.
We aim to provide quality tools at an affordable price.
We hope you will enjoy using this tool for many years. Your
Demolition Breaker (DBR-1500) has been designed for
breaking and chipping concrete, block and masonry products
and is intended for DIY and light trade applications.
Warning! When using mains-powered equipment, basic safety precautions,
including the following, should always be followed to reduce risk of fire,
electric shock, personal injury and material damage.
Read and understand the manual prior to operating this tool.
Save these instructions and other documents supplied with this tool for future reference.
The electric motor has been designed for 230 - 240V only. Always check that the
power supply corresponds to the voltage on the rating plate.
Note: The supply of 230V and 240V on Ozito tools are interchangeable for
Australia and New Zealand.
This tool is double insulated in accordance with 60745-1; therefore no
earth wire is required.
If the supply cord is damaged, it must be replaced by an electrician or a power tool
repairer in order to avoid a hazard.
Note: Double insulation does not take the place of normal safety precautions
when operating this tool. The insulation system is for added protection against
injury resulting from a possible electrical insulation failure within the tool.
Using an Extension Lead
Always use an approved extension lead suitable for the power input of this tool.
Before use, inspect the extension lead for signs of damage, wear and ageing.
Replace the extension lead if damaged or defective.

GENERAL SAFETY INSTRUCTIONS
Warning! Read all instructions. Failure to follow all instructions listed below may
result in electric shock, fire and/or serious injury. The term "power tool" in all of the
warnings listed below refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
Save these instructions
1) Work area
a) Keep work area clean and well lit. Cluttered and 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.
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 safety equipment. Always wear eye protection. Safety equipment such as
dust mask, non-skid safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.
c) Avoid accidental starting. Ensure the switch is in the off-position before
plugging in. Carrying power tools with your finger on the switch or plugging in
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.

GENERAL SAFETY INSTRUCTIONS (cont.)
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
these devices 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 tools
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 and in the manner intended for the particular type of
power tool, 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.
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.
b) If the supply cord is damaged, it must be replaced by the manufacturer, its
service agent or similarly qualified persons in order to avoid a hazard.

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.
Recommendations for the use of a residual current device with a rated residual
current of 30mA or less.
Cutting accessory contacting a “live” wire may make exposed metal parts of the
power tool “live” and could give the operator an electric shock.
It is recommended that the extension lead is a maximum of 25m in length. Do Not
use multiple extension leads.
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 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 and when
drilling/chiselling overhead. Sanding particles can be absorbed by your eyes and
inhaled easily and may cause health complications.
Special requirements:
• Wear ear protectors. Exposure to noise can cause hearing loss.
• Use auxiliary handles supplied with the tool. Loss of control can cause personal injury.

BEFORE ATTACHING OR REMOVING ANY ACCESSORIES, BE SURE TO
DISCONNECT THE DEMOLITION BREAKER FROM THE POWER SUPPLY
Adjusting the Side Handle
The side handle (9) provides additional control, support and guidance for the
demolition breaker.
The side handle (9) is adjustable to any position around the
360° handle collar mount.
The side handle (9) will come assembled to the demolition
breaker, yet the handle locking knob (10) will need to be
tightened to secure the side handle (9) in place.
Loosen the side handle (9) by rotating the handle locking knob
(10) anti clockwise (Fig.1). Adjust the side handle (9) by rotating
around the 360° handle collar mount to the desired position and
retighten by turning the handle locking knob (10) clockwise.
Fitting and Removing SDS Max Accessories
Important! Always lubricate the SDS max
accessory fitment prior to inserting them into the
demolition breaker. Using your finger, apply
grease sparingly to the shaft of the accessory from the tub of grease (14) supplied.
Lubricating the SDS max accessories will prolong the life of your demolition breaker.
Non-lubrication of accessories will void your warranty.
Note: Prior to fitting a SDS max accessory, remove any dust or debris from the
SDS max shank of the accessory.
1. Pull the accessory locking sleeve (2) back towards the
body of the demolition breaker (Fig. 3). Rotate and
insert the SDS max accessory, making sure it has been
inserted as far as it will go, then release the accessory
locking sleeve (2).
2. With the accessory locking sleeve (2) released, check the
SDS max accessory has been locked into place by trying
to pull the SDS max accessory out.
Note: The SDS max accessories will have a small amount (approx. 10-12mm) of
back and forth movement from the SDS max accessory holder (1), this is normal.
3. To remove the SDS max accessory, pull the accessory locking sleeve (2) back
towards the body of the demolition breaker, and remove the SDS max
accessory. Clean the SDS max accessory shank with a dry cloth after removal.
Note: To avoid damage to the SDS max accessory holder (1), only use SDS max
accessories. Damage caused to the SDS max accessory holder (1) by using
incorrect accessories will not be covered under warranty.
Warning! Accessories can be hot after use, always wear gloves to prevent
burns or lacerations.

OPERATION
On/Off Switch
To turn on the demolition breaker, slide the On/Off Switch
(5) to the right (Fig. 4).
To turn off the demolition breaker, slide the On/Off Switch
(5) to the left.
Note: Always wait until the SDS max accessory has
stopped moving before putting down the demolition
breaker.
Variable Speed Dial
Your tool is equipped with a variable speed dial (7). The
impact rate (bpm) can be varied according to the type of
work being performed.
The variable speed dial (7) can be adjusted while the
motor is running with the demolition breaker free from
work, allowing you to adjust the impact rate according the
required application (Fig. 5).
Cold Hammering
If the demolition breaker is stored for long periods of time
or at cold temperatures, the lubrication may become stiff
and the demolition breaker may not hammer initially or the
hammering may be weak.
Should this occur, insert a SDS max accessory into the
demolition breaker, turn the demolition breaker on and
apply the end of the SDS max accessory against a scrap
piece of concrete or timber (Fig. 6). Turn the demolition
breaker on and off every few seconds. After 15 seconds to
2 minutes, the demolition breaker should have started to
hammer normally. The colder the demolition breaker, the
longer it may take to warm up and function like normal.
Note: Always wait until the SDS max accessory has stopped
moving before putting down the demolition breaker.
Operating the Demolition Breaker
For the best penetration rates in concrete, run the demolition breaker with a steady
pressure, but do not use excessive force as this will decrease the efficiency of the
demolition breaker.
Do not use the SDS max flat chisel (11) as a “pry bar”. Using the SDS max flat chisel
(11) for prying or pushing debris away from your work area will damage the SDS max
flat chisel (11) and potentially cause damage to your demolition breaker.
Such damage will void your warranty.
Note: The SDS max flat chisel (11) and the SDS max pointed chisel (12) are
consumable items and are not covered under warranty.

• Keep the ventilation vents of the demolition breaker clean at all times, if
possible, prevent foreign matter from entering the vents.
• After each use, blow air through the demolition breaker housing to ensure it is
free from all dust particles which may build up. Build up of dust particles may
cause the demolition breaker to overheat and fail.
• If the enclosure of the demolition breaker requires cleaning, do not use solvents,
but a moist soft cloth only. Never let any liquid get inside the demolition breaker;
never immerse any part of the demolition breaker into a liquid.
Carbon brushes
When the carbon brushes (Fig.7) wear out, the demolition
breaker will spark and/or stop. Discontinue use as soon as
this happens. They should be replaced prior to
recommencing use of the demolition breaker. Carbon
brushes are a wearing component of the demolition
breaker, therefore not covered under warranty. Continuing
to use the demolition breaker when the carbon brushes
need to be replaced may cause permanent damage to the
demolition breaker. Carbon brushes will wear out after many uses but when the
carbon brushes need to be replaced, take the demolition breaker to an electrician
or a power tool repairer for a quick and low cost replacement. Always replace both
carbon brushes at the same time.
Gear Box Grease Replenishment
The grease in the gearbox will require
replenishment after approximately 50 hours
accumulative use. After this time, add
approximately 30 / 50 grams (approx 2-3
teaspoons) from the tub of grease (14)
(supplied) into the gearbox.
First remove the grease cap (4) from the
demolition breaker by using the spanner (13)
and rotating anti-clockwise (Fig.8). Once
removed, add the grease through this hole. Ensure the grease cap (4) is secured
back into position prior to operation. Further grease (normal ball bearing grease)
can be purchased through your local Bunnings Warehouse.
Note: Ozito Industries will not be responsible for any damage or injuries caused by
the repair of the demolition breaker by an unauthorised person or by mishandling
of the demolition breaker.
