GENERAL POWER TOOL SAFETY WARNINGS

WARNING: Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below 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 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 a 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.

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 and clothing 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.
h) Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

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 remove the battery pack, if detachable, 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 and accessories. 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.
h) Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.
a) Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
b) Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
c) When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
d) Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

5) Battery Tool Use and Care

e) Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.
f) Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 130 °C may cause explosion.
g) Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

6) 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) Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorised service providers.

Grass Trimmer, Brush Cutter and Brush Saw Safety Warnings

a) Do not use the machine in bad weather conditions, especially when there is a risk of lightning. This decreases the risk of being struck by lightning.
b) Thoroughly inspect the area for wildlife where the machine is to be used. Wildlife may be injured by the machine during operation.
c) Thoroughly inspect the area where the machine is to be used and remove all stones, sticks, wires, bones, and other foreign objects. Thrown objects can cause personal injury.
d) Before using the machine, always visually inspect to see that the cutter or blade and the cutter or blade assembly are not damaged. Damaged parts increase the risk of injury.
e) Follow instructions for changing accessories. Improperly tightened blade securing nuts or bolts may either damage the blade or result in it becoming detached.
f) The rated rotational speed of the blade must be at least equal to the maximum rotational speed marked on the machine. Blades running faster than their rated rotational speed can break and fly apart.
g) Wear eye, ear, head and hand protection. Adequate protective equipment will reduce personal injury by flying debris or accidental contact with the cutting line or blade.
h) While operating the machine, always wear non-slip and protective footwear. Do not operate the machine when barefoot or wearing open sandals. This reduces the chance of injury to the feet from contact with the moving cutters or lines.
i) While operating the machine, always wear safety footwear. Do not operate the machine when barefoot or wearing open sandals. This reduces the chance of injury to the feet from contact with a moving cutter, line or blade.
j) While operating the machine, always wear long trousers. Exposed skin increases the likelihood of injury from thrown objects.
k) Keep bystanders away while operating the machine. Thrown debris can result in serious personal injury.
1) Always use two hands when operating the machine. Holding the machine with both hands will avoid loss of control.
m) Hold the machine by the insulated gripping surfaces only, because the cutting line or blade may contact hidden wiring. Cutting line or blades contacting a "live" wire may make

exposed metal parts of the machine "live" and could give the operator an electric shock.

n) Always keep proper footing and operate the machine only when standing on the ground. Slippery or unstable surfaces may cause a loss of balance or control of the machine.
o) Do not operate the machine on excessively steep slopes. This reduces the risk of loss of control, slipping and falling which may result in personal injury.
p) When working on slopes, always be sure of your footing, always work across the face of slopes, never up or down and exercise extreme caution when changing direction. This reduces the risk of loss of control, slipping and falling which may result in personal injury.
q) Keep all parts of the body away from the cutter, line or blade when the machine is operating. Before you start the machine, make sure the cutter, line or blade is not contacting anything. A moment of inattention while operating the machine may result in injury to yourself or others.
r) Do not operate the machine above waist height. This helps prevent unintended cutter or blade contact and enables better control of the machine in unexpected situations.
s) When cutting brush or saplings that are under tension, be alert for spring back. When the tension in the wood fibres is released, the brush or sapling may strike the operator and/or throw the machine out of control.
t) Use extreme caution when cutting brush and saplings. The slender material may catch the blade and be whipped toward you or pull you off balance.
u) Maintain control of the machine and do not touch cutters, lines or blades and other hazardous moving parts while they are still in motion. This reduces the risk of injury from moving parts.
v) Carry the machine with the machine switched off and away from your body. Proper handling of the machine will reduce the likelihood of accidental contact with a moving cutter, line or blade.
w) When transporting or storing the machine, always fit the cover on metal blades. Proper handling of the machine will reduce the likelihood of accidental contact with the blade.
x) Only use replacement cutters, lines, cutting heads and blades specified by the manufacturer. Incorrect replacement parts may increase the risk of breakage and injury.
y) When clearing jammed material or servicing the machine, make sure the switch is off and the battery pack is removed. Unexpected starting of the machine while clearing jammed material or servicing may result in serious personal injury.

Blade Thrust Causes and Related Warnings

Blade thrust is a sudden sideways, forward or backward motion of the machine, which may occur when the blade jams or catches on an object such as a sapling or a tree stump. It can be violent enough to cause the machine and/or operator to be propelled in any direction, and possibly lose control of the machine.

Blade thrust and its related hazards can be avoided by taking proper precautions as given below.

a) Maintain a firm grip with both hands on the machine and position your arms to resist blade thrust. Position your body to the left side of the machine. Blade thrust can increase the risk of injury due to the machine moving unexpectedly. Blade thrust can be controlled by the operator if proper precautions are taken.
b) If the blade binds, or when interrupting a cut for any reason, switch the machine off and hold the machine

motionless in the material until the blade comes to a complete stop. While the blade is binding, never attempt to remove the machine from the material or pull the machine backward while the blade is in motion, otherwise blade thrust may occur. Investigate and take corrective actions to eliminate the cause of blade binding.

c) Do not use blunt or damaged blades. Blunt or damaged blades increase the risk of jamming or catching on an object, resulting in blade thrust.
d) Always maintain good visibility of the material being cut. Blade thrust is more likely to occur in areas where it is difficult to see the material being cut.
e) If you are approached by another person while operating the machine, switch the machine off. There is an increased risk of injury to other persons being struck by the moving blade in the event of blade thrust.

Additional Safety Information

a) Always use the shoulder harness when operating.
b) Always keep the handle between the operator and blade during operation.
c) Do not cut material larger than 13 mm (0.5") diameter.
d) The blade will continue to spin after the unit is shut off. Maintain control until the blade has stopped.

Brushsaw Cutting (Fig. R, T–V)

WARNING: Keep all bystanders clear and away from the area you are cutting in at least two to three times the length of the tree being felled.
WARNING: Flying debris can cause serious injury. To reduce the risk that the brushesaw blade will crack or shatter, avoid all contact with stones, rocks or the ground. Keep the brushesaw blade parallel with the ground.
WARNING: Only use sharp brushesaw blades. Dull saw teeth may cause the brushesaw blade to crack or shatter.

Helpful Cutting Tips

With the DCMBC723 on, angle it and cut from right to left (anticlockwise direction) as shown in Fig. R.

Maintain a minimum distance of 610 mm (24") between the guard and your feet as shown in Fig. U.

WARNING: Keep the rotating blade roughly parallel with the ground (tilted no more than 30°). This brush saw is not an edger. DO NOT TILT the brush saw so that the blade is spinning near a right angle to the ground. Flying debris can cause serious injury as shown in Fig. V.

Brush saw blades can be used for clearing brush and cutting small diameter trees up to 40 mm (1.5"). Do not attempt cutting a tree with a larger diameter, use a chain saw instead. When a brush saw blade is used to cut down small trees, users should place the left side of the guard against the tree trunk before beginning to cut. This will keep the guard against the tree during the cutting operation and will reduce the risk of loss of control and possible kickback.

• The brush saw cuts best when passing the unit from the right to left. This will help reduce the possibility of the brush saw kicking back towards the operator.
• Before starting the cut, allow the brush saw blade to reach full speed. Do not force the brush saw blade into the tree or brush, allow the brush saw blade to do the cutting. Place the brush saw blade to the right of the tree, using the unshaded area of the brush saw blade, as shown below.

- The risk of kickback is highest when cutting in the dark shaded area of the brushesaw blade, as shown below. To reduce the risk of kickback and personal injury, do not use this area of the brushesaw blade for cutting trees or shrubs. Special techniques using the lighter shaded areas of the blade to cut shrubs and trees should only be used by experienced operators with specialized training in the use and control of the brushesaw.
