IMPORTANT SAFETY CONSIDERATIONS
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 corded 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 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 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. If operating a power tool in a damp location is unavoidable, use a residual current device (RCD)
protected supply. Use of an RCD 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 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 carrying a tool when the power is 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 jewelry. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewelry 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. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
e. 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.
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 supplied power cord is damaged, it must be replaced by the manufacturer, its service
agent or similarly qualified persons in order to avoid a hazard.
DEMOLITION BREAKER USE AND CARE
•Do not modify the Demolition Breaker in any way. Unauthorized modification may impair the
function and/or safety and could affect the life of the equipment. There are specific applications
for which the Demolition Breaker was designed.
•Always check of damaged or worn out parts before using the Demolition Breaker. Broken
parts will affect the Demolition Breaker operation. Replace or repair damaged or worn parts
immediately.
•Store idle Demolition Breaker. When Demolition Breaker is not in use, store it in a secure
place out of the reach of children. Inspect it for good working condition prior to storage and
before re-use.
•Wear ear protection.Always use ear protection when operating the Demolition Breaker to
prevent potential hearing loss.
•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.

•Always use an approved extension cord suitable for the power input of this tool. Before use,
inspect the extension cord for signs of damage, wear and ageing. Replace the extension cord if
damaged or defective.
•When using an extension cord on a reel, always unwind the cord completely. Use of an
extension cord not suitable for the power input of the tool or which is damaged or defective may
result in a risk of fire and electric shock.
•It is recommended that the extension cord is a maximum of 82 feet in length. Do not use multiple
extension cords.
•Before drilling into walls, ceilings etc, ensure there are no concealed power cables or pipes in the
cavity.
•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.

WARNING
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains
chemicals known to the State of California to cause cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, 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 specially designed to filter out microscopic particles.
