GENERAL POWER TOOL SAFETY WARNINGS

WARNING: Read all safety warnings, instructions, indications 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.

5) Battery Tool Use and Care

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.
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.

Pruner Safety Warnings

a) Keep all parts of the body away from the saw chain when the pruner is operating. Before you start the pruner, make sure the saw chain is not contacting anything. A moment of inattention while operating pruners may cause entanglement of your clothing or body with the saw chain.
b) Always hold the pruner with your right hand on the rear handle and your left hand on the front handle. Holding the pruner with a reversed hand configuration increases the risk of personal injury and should never be done.
c) Hold the pruner by insulated gripping surfaces only, because the saw chain may contact hidden wiring.

Saw chains contacting a "live" wire may make exposed metal parts of the pruner "live" and could give the operator an electric shock.

d) Wear safety glasses and hearing protection. Further protective equipment for, head, hands, legs and feet is recommended. Adequate protective clothing will reduce personal injury from flying debris or accidental contact with the saw chain.
e) Do not operate a pruner saw in a tree, on a ladder, from a rooftop, or any unstable support. Operation of a pruner saw in this manner could result in serious personal injury.
f) Always keep proper footing and operate the pruner only when standing on fixed, secure and level surface. Slippery or unstable surfaces may cause a loss of balance or control of the pruner.
g) When cutting a limb that is under tension, be alert for spring back. When the tension in the wood fibers is released, the spring loaded limb may strike the operator and/or throw the pruner out of control.
h) Use extreme caution when cutting brush and saplings. The slender material could catch the saw chain and be whipped toward you or pull you off balance.
i) Carry the pruner with the pruner switched off and away from your body. When transporting or storing the pruner always fit the guide bar cover. Proper handling of the pruner will reduce the likelihood of accidental contact with the moving saw chain.
j) Follow instructions for lubricating, chain tensioning and changing the bar and saw chain. Improperly tensioned or lubricated chain could break the pruner chain.
k) Keep handles dry, clean, and free from oil and grease. Greasy, oily handles are slippery, causing loss of control.
1) Cut wood only. Do not use pruner for purposes not intended. For example: do not use pruner for cutting metal, plastic, masonry or non-wood building materials. Use of the pruner for operations different than intended could result in a hazardous situation.
m) Maintain a firm grip, with thumbs and fingers encircling the pruner handles, with both hands on the pruner. Maintaining control of the pruner will reduce the risk of losing control. Do not let go of the pruner.
n) Do not overreach and do not cut above shoulder height. This enables better control of the pruner in unexpected situations.
o) Only use replacement bars and chains specified by the manufacturer. Incorrect replacement bars and chains can cause chain breakage and increase the risk of injury.
p) Follow the manufacturer's sharpening and maintenance instructions for the pruner chain. Decreasing the depth gauge height can lead to increased risk of injury.

q) This pruner is not intended for tree felling. Use of the pruner for operations different than intended could result in serious injury to the operator or bystander.
r) Follow all instructions when clearing jammed material, storing or servicing the pruner saw. Make sure the switch is off and the battery pack is removed.

Causes and Operator Prevention of Kickback:

Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut.

Tip contact in some cases may cause a sudden reverse reaction, kicking the guide bar up and back towards the operator.

Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator.

Either of these reactions may cause you to lose control of the saw which could result in serious personal injury. Do not rely exclusively upon the safety devices built into your saw. As a pruner user, you should take several steps to keep your cutting jobs free from accident or injury.

Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:

a) Maintain a firm grip, with thumbs and fingers encircling the pruner handles, with both hands on the saw and position your body and arm to allow you to resist kickback forces. Kickback forces can be controlled by the operator, if proper precautions are taken. Do not let go of the pruner.
b) Do not overreach and do not cut above shoulder height. This helps prevent unintended tip contact and enables better control of the pruner in unexpected situations.
c) Only use replacement bars and chains specified by the manufacturer. Incorrect replacement bars and chains may cause chain breakage and/or kickback.
d) Follow the manufacturer's sharpening and maintenance instructions for the saw chain. Decreasing the depth gauge height can lead to increased kickback.

The Following Precautions Should Be Followed to Minimize Kickback:

1. Grip saw firmly. Hold the pruner firmly with both hands when the motor is running. Use a firm grip with thumbs and fingers encircling the pruner handles. Pruner will pull forward when cutting on the bottom edge of the bar, and push backward when cutting along the top edge of the bar.
2. Do not over reach.
3. Keep proper footing and balance at all times.
4. Don't let the nose of the guide bar contact a log, branch, ground or other obstruction.
5. Don't cut above shoulder height.
6. Use devices such as low kickback chain and reduced kickback guide bars that reduce the risks associated with kickback.

7. Only use replacement bars and saw chains specified by the manufacturer or the equivalent.

8. Never let the moving saw chain contact any object at the tip of the guide bar.

9. Keep the working area free from obstructions such as other trees, branches, rocks, fences, stumps, etc. Eliminate or avoid any obstruction that your saw chain could hit while you are cutting through a particular log or branch.

10. Keep your saw chain sharp and properly tensioned. A loose or dull chain can increase the chance of kickback. Check tension at regular intervals with the motor stopped and tool unplugged, never with the motor running.

11. Begin and continue cutting only with the chain moving at full speed. If the chain is moving at a slower speed, there is a greater chance for kickback to occur.

12. Cut one log at a time.

13. Use extreme caution when re-entering a previous cut. Engage the ribbed bumpers 21 onto the wood and allow the chain to reach full speed before proceeding with a cut.

14. Do not attempt plunge cuts or bore cuts.

15. Watch for shifting logs or other forces that could close a cut and pinch or fall into chain.

Kickback Safety Features

WARNING: The following features are included on your saw to help reduce the hazard of kickback; however such features will not totally eliminate this dangerous reaction. As a pruner user do not rely only on safety devices. You must follow all safety precautions, instructions, and maintenance in this manual to help avoid kickback and other forces which can result in serious injury.

• Reduced-Kickback Guide Bar, designed with a small radius tip which reduces the size of the kickback danger zone on bar tip. A reduced-kickback guide bar is one which has been demonstrated to significantly reduce the number and seriousness of kickbacks when tested in accordance with safety requirements for electric pruners.
• Low-Kickback Chain, designed with a contoured depth gauge and guard link which deflects kickback force and allows wood to gradually ride into the cutter. A low-kickback chain is a chain which has met kickback performance requirements of ANSI B175.1–2012.
• Do not operate pruner while in a tree, on a ladder, on a scaffold, or from any unstable surface.
• Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring. Contact with a "live" wire will make exposed metal parts of the tool "live" and shock the operator.
• Do not attempt operations beyond your capacity or experience. Read thoroughly and understand completely all instructions in this manual.
• Before you start pruner, make sure saw chain is not contacting any object.
• Do not operate a pruner with one hand! Serious injury to the operator, helpers, or bystanders may result from one-handed operation. A pruner is intended for two-handed use only.
• Keep the handles dry, clean, and free of oil or grease.
• Do not allow dirt, debris, or sawdust to build up on the motor or outside air vents.

• Stop the pruner before setting it down.

• Do not cut vines and/or small under-brush.

• Use extreme caution when cutting small size brush and saplings because slender material may catch the saw chain and be whipped toward you or pull you off balance.

* The red light will continue to blink, but a yellow indicator light will be illuminated during this operation. Once the battery pack has reached an appropriate temperature, the yellow light will turn off and the charger will resume the charging procedure. The compatible charger(s) will not charge a faulty battery pack. The charger will indicate faulty battery by refusing to light.

nOTE: This could also mean a problem with a charger.

If the charger indicates a problem, take the charger and battery pack to be tested at an authorised service centre.

Hot/Cold Pack Delay

When the charger detects a battery pack that is too hot or too cold, it automatically starts a Hot/Cold Pack Delay, suspending charging until the battery pack has reached an appropriate temperature. The charger then automatically switches to the pack charging mode. This feature ensures maximum battery pack life.

A cold battery pack will charge at a slower rate than a warm battery pack. The battery pack will charge at that slower rate throughout the entire charging cycle and will not return to maximum charge rate even if the battery pack warms.

The DCB118 charger is equipped with an internal fan designed to cool the battery pack. The fan will turn on automatically when the battery pack needs to be cooled. Never operate the charger if the fan does not operate properly or if ventilation slots are blocked. Do not permit foreign objects to enter the interior of the charger.

Electronic Protection System

XR Li-Ion tools are designed with an Electronic Protection System that will protect the battery pack against overloading, overheating or deep discharge.

The tool will automatically turn off if the Electronic Protection System engages. If this occurs, place the lithium-ion battery pack on the charger until it is fully charged.

Wall Mounting

These chargers are designed to be wall mountable or to sit upright on a table or work surface. If wall mounting, locate the charger within reach of an electrical outlet, and away from a corner or other obstructions which may impede air flow. Use the back of the charger as a template for the location of the mounting screws on the wall. Mount the charger securely using drywall screws (purchased separately) at least 25.4 mm long with a screw head diameter of 7–9 mm, screwed into wood to an optimal depth leaving approximately 5.5 mm of the screw exposed. Align the slots on the back of the charger with the exposed screws and fully engage them in the slots.

Charger Cleaning Instructions

WARNING: Shock hazard. Disconnect the charger from the AC outlet before cleaning. Dirt and grease may be removed from the exterior of the charger using a cloth or soft non-metallic brush. Do not use water or any cleaning solutions. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.

terminals are protected and well insulated from materials that could contact them and cause a short circuit. NOTE: Lithium-ion batteries should not be put in checked baggage.

DEWALT batteries comply with all applicable shipping regulations as prescribed by industry and legal standards which include UN Recommendations on the Transport of Dangerous Goods; International Air Transport Association (IATA) Dangerous Goods Regulations, International Maritime Dangerous Goods (IMDG) Regulations, and the European Agreement Concerning The International Carriage of Dangerous Goods by Road (ADR). Lithium-ion cells and batteries have been tested to section 38.3 of the UN Recommendations on the Transport of Dangerous Goods Manual of Tests and Criteria.

In most instances, shipping a DEWALT battery pack will be excepted from being classified as a fully regulated Class 9 Hazardous Material. In general, only shipments containing a lithium-ion battery with an energy rating greater than 100 Watt Hours (Wh) will require being shipped as fully regulated Class 9. All lithium-ion batteries have the Watt Hour rating marked on the pack. Furthermore, due to regulation complexities, DEWALT does not recommend air shipping lithium-ion battery packs alone regardless of Watt Hour rating. Shipments of tools with batteries (combo kits) can be air shipped as excepted if the Watt Hour rating of the battery pack is no greater than 100 Wh. Regardless of whether a shipment is considered excepted or fully regulated, it is the shipper's responsibility to consult the latest regulations for packaging, labeling/marking and documentation requirements.

The information provided in this section of the manual is provided in good faith and believed to be accurate at the time the document was created. However, no warranty, expressed or implied, is given. It is the buyer's responsibility to ensure that its activities comply with the applicable regulations.

Transporting the FLEXVOLT™ Battery

The DEWALT FLEXVOLT™ battery has two modes: Use and Transport.

Use Mode: When the FLEXVOLT™ battery stands alone or is in a DEWALT 18V product, it will operate as an 18V battery. When the FLEXVOLT™ battery is in a 54V or a 108V (two 54V batteries) product, it will operate as a 54V battery.

Transport Mode: When the cap is attached to the FLEXVOLT™ battery, the battery is in Transport mode. Keep the cap for shipping.

When in Transport mode, strings of cells are electrically disconnected within the pack resulting in 3 batteries with a

Technical line drawing of a mechanical component with no visible text or symbols

lower Watt hour (Wh) rating as compared to 1 battery with a higher Watt hour rating. This increased quantity of 3 batteries with the lower Watt hour rating can exempt the pack from certain shipping regulations that are imposed upon the higher Watt hour batteries.

For example, the Transport Wh rating might indicate 3 x 36 Wh, meaning

Example of Use and Transport Label Marking

Use: 108 Wh

Transport: 3x36 Wh

3 batteries of 36 Wh each. The Use Wh rating might indicate 108 Wh (1 battery implied).

Common Cutting Techniques

Limbing

Removing the branches from a fallen tree. When limbing, leave larger lower limbs to support the log off the ground. Remove the small limbs in one cut. Branches under tension should be cut from the bottom of the branch towards the top to avoid binding the pruner as shown below. Trim limbs from opposite side keeping tree stem between you and pruner. Never make cuts with pruner between your legs or straddle the limb to be cut.

Bucking

WARNING: Recommend that first-time users should practice cutting on a pruner horse.

Cutting a felled tree or log into lengths. How you should cut depends on how the log is supported. Use a saw horse whenever possible as shown below.

Technical illustration of a wooden log being cut with chains, showing grain and structural components (no text or symbols)

1. Always start a cut with the pruner chain running at full speed.
2. Place the ribbed bumper 21 of the pruner behind the area of the initial cut as shown below.
3. Turn the pruner on then rotate the pruner chain and bar down into the tree, using the ribbed bumper as a hinge.

4. Once the pruner gets to a 45^ angle, level the pruner again and repeat steps until you cut fully through.

5. When the tree is supported along its entire length, make a cut from the top (overbuck), but avoid cutting the earth as this will dull your pruner quickly.

CUT FROM TOP (OVERBUCK) AVOID CUTTING EARTH 21

- When supported at one end first, cut 1/3 the diameter from the underside (underbuck). Then make the finishing cut by overbucking to meet the first cut as shown below.

2nd CUT OVERBUCK (2/3 DIAMETER) TO MEET 1st CUT (TO AVOID PINCHING) 1st CUT UNDERBUCK (1/3 DIAMETER) AVOID SPLINTERING

- When supported at both ends. First, cut 1/3 down from the top overbuck. Then make the finished cut by underbucking the lower 2/3 to meet the first cut as shown below.

1st CUT OVERBUCK (1/3 DIAMETER) TO AVOID SPLINTERING 2nd CUT UNDERBUCK (2/3 DIAMETER) TO MEET 1st CUT (TO AVOID PINCHING)

- When on a slope always stand on the uphill side of the log. When "cutting through," to maintain complete control reduce the cutting pressure near the end of the cut without relaxing your grip on the pruner handles. Don't let the chain contact the ground. After completing the cut, wait for the pruner chain to stop before you move the pruner. Always stop the motor before moving from cut to cut.

Each time the chain is sharpened, it loses some of the low kickback qualities and extra caution should be used. It is recommended that a saw chain be sharpened no more than four times.

nOTE: The cutters will dull immediately if they touch the ground/dirt or a nail while cutting.

To get the best possible performance from your pruner it is important to keep the teeth of the saw chain sharp. Follow these helpful tips for proper saw chain sharpening:

1. For best results use a 11/64" (4.5 mm) file and a file holder or filing guide to sharpen your saw chain. This will ensure you always get the correct sharpening angles.
2. Place the file holder flat on the top plate and depth gauge of the cutter.
3. Keep the correct top plate 23 filing angle line of 30^ on your file guide parallel with your chain (file at 60^ from chain viewed from the side) as shown in Fig. L.
4. Sharpen cutters on one side of the chain first. File from the inside of each cutter to the outside. Then turn your saw around and repeat the processes (2, 3, 4) for cutters on the other side of the chain.

NOTE: Use a flat file to file the tops of the rakers (portion of chain link in front of the cutter) so they are about 0.025" (0.635 mm) below the tips of the cutters as shown in Fig. M.

1. Keep all cutter lengths equal as shown in Fig. N.
2. If damage is present on the chrome surface of the top plates or side plates, file back until such damage is removed.

CAUTION: After filing, the cutter will be sharp, so use extra radiation during this process.
