EnglishSafety Notes
General Power Tool Safety Warnings
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 mainsoperated (corded) power tool or battery-operated (cordless)power tool.

WARNINGWork 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 ordust. 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 withearthed (grounded) power tools. Unmodified plugs andmatching 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 isearthed 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 awayfrom heat, oil, sharp edges and 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 suitablefor 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) protectedsupply. 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
1 609 92A 2FT | (2.3.16)

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 frommoving parts. Loose clothes, jewellery or long hair can becaught 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 and care
 Do not force the power tool. Use the correct power toolfor your application. The correct power tool will do thejob better and safer at the rate for which it was designed.
 Do not use the power tool if the switch does not turn iton and off. Any power tool that cannot be controlled withthe switch is dangerous and must be repaired.
 Disconnect the plug from the power source and/or thebattery pack from the power tool before making any
adjustments, changing accessories, or storing power
tools. Such preventive safety measures reduce the risk ofstarting the power tool accidentally.
 Store idle power tools out of the reach of children anddo not allow persons unfamiliar with the power tool orthese 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 othercondition 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 bindand are easier to control.
 Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into accountthe working conditions and the work to be performed.
Use of the power tool for operations different from thoseintended 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 handle(s), if supplied with the tool. Lossof 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 metalparts of the power tool “live” and could give the operator anelectric shock.
 Use suitable detectors to determine if utility lines are
hidden in the work area or call the local utility company
for assistance. Contact with electric lines can lead to fireand electric shock. Damaging a gas line can lead to explosion. Penetrating a water line causes property damage or
may cause an electric shock.
 When working with the machine, always hold it firmly
with both hands and provide for a secure stance. The
power tool is guided more secure with both hands.
 Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand.
 Always wait until the machine has come to a complete
stop before placing it down. The tool insert can jam andlead to loss of control over the power tool.
Products sold in GB only: Your product is fitted with a
BS 1363/A approved electric plug with internal fuse (ASTA
approved to BS 1362).
If the plug is not suitable for your socket outlets, it should be
cut off and an appropriate plug fitted in its place by an authorised customer service agent. The replacement plug shouldhave the same fuse rating as the original plug.
The severed plug must be disposed of to avoid a possible
shock hazard and should never be inserted into a mains socket elsewhere.
Products sold in AUS and NZ only: Use a residual current device (RCD) with a rated residual current of 30 mA or less.
