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 the 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 that may ignite 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 the 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 the 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. The 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. The 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 a dust mask, non‑skid safety shoes, hard hats, 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 a power source and/or battery pack, picking up, or carrying the tool. Carrying power tools with your finger on the switch or energizing 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 jewelry. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, 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. The use of dust collection can reduce dust‑related hazards.
    h ) Do not let familiarity gained from the 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 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 the 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 the 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 behavior 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 265 °F (130 °C) may cause an 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 authorized 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 power tool 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, the 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 in a tree. Operation of a pruner while up in a tree can result in personal injury.
f ) Always keep proper footing and operate the pruner only when standing on fixed, secure and level surfaces. 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 by the front handle with the pruner switched off and away from your body. 
When transporting or storing the pruner always fit the guide bar scabbard. 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 accessories. An 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.
l ) Cut wood only. Do not use pruner for purposes not intended. For example: do not use a pruner for cutting 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 an increased risk of injury.

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 toward the operator.
Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back toward 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 accidents or injuries.
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 overreach.
  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 chains and reduced kickback guide bars that reduce the risks associated with kickbacks.
  7. Only use replacement bars and chains specified by the manufacturer or the equivalent.
  8. Never let the moving 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 the 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 a 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 the chain.

Kickback Safety Features
warning 4WARNING: 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 kickbacks 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 the bar tip. A reduced ‑ kickback guide bar is one that 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 the wood to gradually ride into the cutter. A low‑kickback chain is a chain that has met the kickback performance requirements of ANSI B175.1–2012.
  • Do not operate the pruner while in a tree, on a ladder, on a scaffold, or on an unstable surface.
  • Hold the tool by insulating 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 the pruner, make sure the 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 a 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 underbrush.
  • Use extreme caution when cutting small-size brushes and saplings because slender material may catch the saw chain and be whipped toward you or pull you off balance.

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 sides keeping the tree stem between you and the pruner. Never make cuts with a pruner between your legs or straddle the limb to be cut.DEWALT DCCS623 20V Max Pruner Limbing

Bucking
warning 4 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 pruner horse whenever possible as shown below.DEWALT DCCS623 20V Max Pruner Bucking

  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 the steps until you cut fully through.
  5. When the tree is supported along its entire length, make a cut from the top (over a buck), but avoid cutting the earth as this will dull your pruner quickly.

CUT FROM THE TOP (OVERBECK) AND AVOID CUTTING EARTH

DEWALT DCCS623 20V Max Pruner fig13

• When supported at one end first, cut 1/3 the diameter from the underside (Funderburk). Then make the finishing cut by overbooking to meet the first cut as shown below.DEWALT DCCS623 20V Max Pruner Limbing1

• When supported at both ends. First, cut 1/3 down from the top overbook. Then make the finished cut by under-bucking the lower 2/3 to meet the first cut as shown below.DEWALT DCCS623 20V Max Pruner fig14

• 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.

warning 4WARNING: Do not over-file chain rakers, this will increase the risk of kickback. If the chain has been sharpened more than four times, replace it. 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 an 11/64″ (4.5mm) 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 the 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 the chain viewed from the side) as shown in Fig. N.
  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 (a portion of chain link in front of the cutter) so they are about .025″ (.635 mm) below the tips of the cutters as shown in  Fig. O. Keep all cutter lengths equal as shown in Fig. P.
  5. If damage is present on the chrome surface of the top plates or side plates, file back until such damage is removed.
