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.

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.

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 Instructions for Rotary Hammers

• Wear ear protectors. Exposure to noise can cause hearing loss.
• Use auxiliary handles supplied with the tool. Loss of control can cause personal injury.
•	Hold power tools by insulated gripping surfaces when performing an operation
	where the cutting tool may contact hidden wiring or its own cord. Contact with a “live”
	wire will make exposed metal parts of the tool “live” and shock the operator.
• Use clamps or other practical way to secure and support the workpiece to a stable
	platform. Holding the work by hand or against your body is unstable and may lead to loss of
	control.
•	Wear safety goggles or other eye protection. Hammering operations cause chips to
	fly. Flying particles can cause permanent eye damage. Wear a dust mask or respirator for
	applications that generate dust. Ear protection may be required for most applications.
• Keep a firm grip on the tool at all times. Do not attempt to operate this tool without
	holding it with both hands. It is recommended that the side handle be used at all times.
	Operating this tool with one hand will result in loss of control. Breaking through or encountering
	hard materials such as re-bar may be hazardous as well. Tighten the side handle securely
	before use.
• The hammer is only for light chiselling applications.
• The forward/reverse switch must be in the forward position when chiselling.
• Do not use this tool to mix or pump easily combustible or explosive fluids (benzine, alcohol,
	etc.).
• Do not mix or stir inflammable liquids labelled accordingly.
• Do not operate this tool for long periods of time. Vibration caused by hammer action may
	be harmful to your hands and arms. Use gloves to provide extra cushion and limit exposure
	by taking frequent rest periods.
• Do not recondition bits yourself. Chisel reconditioning should be done by an authorized
	specialist. Improperly reconditioned chisels could cause injury.
• Wear gloves when operating tool or changing bits. Accessible metal parts on the tool and

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.

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)If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of a GFCI 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 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.

bits may get extremely hot during operation. Small bits of broken material may damage bare

hands.

• Never lay the tool down until the bit has come to a complete stop. Moving bits could

cause injury.

• Do not strike jammed bits with a hammer to dislodge them. Fragments of metal or

material chips could dislodge and cause injury.

• Slightly worn chisels can be resharpened by grinding.

• Keep the power cord away from the rotating bit. Do not wrap the cord around any part

of your body. An electric cord wrapped around a spinning bit may cause personal injury and

loss of control.

• Air vents often cover moving parts and should be avoided. Loose clothes, jewellery or

long hair can be caught in moving parts.

• An extension cord must have adequate wire size (AWG or American Wire Gauge) for

safety. The smaller the gauge number of the wire, the greater the capacity of the cable, that

is 16 gauge has more capacity than 18 gauge. An undersized cord will cause a drop in line

voltage resulting in loss of power and overheating. When using more than one extension to

make up the total length, be sure each individual extension contains at least the minimum

wire size. The following table shows the correct size to use depending on cord length and

nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge

number, the heavier the cord.

NOTE: Do not overheat the bit (discoloration) while grinding a new edge. Badly worn chisels require reforging. Do not reharden and temper the chisel.

WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety glasses. Also use face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT:

•ANSI Z87.1 eye protection (CAN/CSA Z94.3),

•ANSI S12.6 (S3.19) hearing protection,

•NIOSH/OSHA/MSHA respiratory protection.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains 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 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.

•Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and other construction activities. Wear protective clothing and wash exposed areas with soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may promote absorption of harmful chemicals.

WARNING: Use of this tool can generate and/or disburse dust, which may cause serious and permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory protection appropriate for the dust exposure. Direct particles away from face and body.

WARNING: Always use eye protection. All users and bystanders must wear eye protection that conforms to ANSI Z87.1.

WARNING: Always wear proper personal hearing protection that conforms to ANSI S12.6 (S3.19) during use. Under some conditions and duration of use, noise from this product may contribute to hearing loss.
