Safety - General power tool safety warnings
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.
Work Area Safety
Keep work area clean and well lit. Cluttered or dark areas invite accidents.
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.
Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
Electrical safety
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.
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.
Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
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.
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.
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.
Personal Safety
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.
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.
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.
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.
Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected
situations.
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.
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.

Power Tool Use
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.
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.
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.
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.
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.
Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are
easier to control.
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.
Service
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.
Hammer Safety Warnings
Wear ear protectors. Exposure to noise can cause hearing loss.
Use auxiliary handles, 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.
Additional Safety Instructions For Breakers
Personal Safety
Use the product only when it is in technically faultless condition.
Never tamper with or modify the tool in any way.
When chiseling into ceilings, walls and floors, always make sure that you have a safe and firm stance. A sudden break-through
can affect your balance!
Apply appropriate safety measures at the opposite side of the workpiece in work that involves breaking through. Parts breaking
away could fall out and / or fall down causing injury to other persons.
You and any other persons in the vicinity must wear suitable eye protection, a hard hat, ear protection, protective gloves and
respiratory protection while the tool is in use.
Wear protective gloves also when changing the accessory tool. Touching the accessory tool can result in cuts and burns.
Wear eye protection. Flying fragments can injure the body and eyes.
Before starting work, check the hazard class of the dust that will be produced when working. Use an industrial vacuum cleaner
with an officially approved protection class in compliance with the locally applicable dust protection regulations. Dust from

6 | P a g e
materials such as lead-based paint, certain types of wood and concrete/masonry/stone containing quartz, minerals or metal can
be harmful to health.
Make sure that the workplace is well ventilated and, where necessary, wear a respirator appropriate for the type of dust
generated. Contact with or inhalation of the dust may cause allergic reactions and/or respiratory or other diseases among
operators or bystanders. Certain kinds of dust are classified as carcinogenic such as oak and beech dust, especially in conjunction
with additives for wood conditioning (chromate, wood preservative). Material containing asbestos may be handled only by
specialists.
Take breaks and do physical exercises to improve the blood circulation in your fingers. Exposure to vibration during long periods
of work can lead to disorders of the blood vessels and nervous system in the fingers, hands and wrists.
Electrical Safety
Before beginning work, check the working area for concealed electric cables or gas and water pipes. External metal parts of the
power tool can become live, presenting a risk of electric shock, if you accidentally damage an electric cable.
Careful Handling and Use of Electric Tools
Wait until the power tool stops completely before you lay it down.

fault circuit interrupter are present in the power supply and that these are correctly connected.
Do not use the product unless these safety measures are in place and fully operational.
WARNING
A damaged supply cord presents a hazard! Do not touch the supply cord or extension cord if damaged while working.
Disconnect the supply cord plug from the power outlet.
Check the appliance’s supply cord at regular intervals and have it replaced by a qualified specialist if found to be damaged.
Full approval must be obtained from the site engineer or architect prior to beginning the work.
Chiseling 5
1. Plug the supply cord into the power outlet. Working at low temperatures: The hammering mechanism works only when the
power tool has reached a minimum operating temperature. Bring the chisel into contact with the base material and allow the
power tool to run under no load until the minimum operating temperature is reached. If necessary, repeat this procedure until
the hammering mechanism begins to operate.
2. Bring the chisel into contact with the workpiece about 80 -100 mm (3¹⁄₈" - 4") from its edge.
3. To switch the power tool on, push the on/off switch to the right. ➥The on/off switch remains engaged in this position (on the
right).
4. To switch the power tool off, push the on/off switch to the left. ➥The on/off switch remains engaged in this position (on the
left). If inadequate pressure is applied, the chisel will jump around uncontrollably. Application of excessive pressure will result in
a loss of chiseling performance. When working close to reinforcing bars, always guide the tip of the chisel toward the edge of
the workpiece, not toward a reinforcing bar.
