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.

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.

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.

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.

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.

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.

General Chain Saw Safety Warnings

WARNING: Additional safety warnings for chainsaws.

a ) Keep all parts of the body away from the saw chain when the chain saw is operating. Before you start the chain saw, make sure the saw chain is not contacting anything. A moment of inattention while operating chain saws may cause entanglement of your clothing or body with the saw chain.
b ) Always hold the chain saw with your right hand on the rear handle and your left hand on the front handle. Holding the chain saw with a reversed hand configuration increases the risk of personal injury and should never be done.
c) Hold the chain saw 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 chain saw “live” and could give the operator an electric shock.
d ) Wear eye protection. Further protective equipment for hearing, head, hands, legs and feet is recommended. Adequate protective equipment will reduce personal injury from flying debris or accidental contact with the saw chain.
e) Do not operate a chain saw on a ladder, from a rooftop, or any unstable support. Operation of a chain saw in this manner could result in serious personal injury.
f ) Always keep proper footing and operate the chain saw only when standing on fixed, secure and level surface. Slippery or unstable surfaces may cause a loss of balance or control of the chain saw.
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 chain saw out of control.
h ) Use extreme caution when cutting brush and saplings. The slender material may catch the saw chain and be whipped toward you or pull you off balance.
i ) Carry the chain saw by the front handle with the chain saw switched off and away from your body. When transporting or storing the chain saw always fit the guide bar scabbard. Proper handling of the chain saw will reduce the likelihood of accidental contact with the moving saw chain.
j ) Follow instructions for lubricating, chain tensioning and changing the bar and chain.
Improperly tensioned or lubricated chain may either break or increase the chance for kickback.
k) Cut wood only. Do not use chain saw for purposes not intended. For example: do not use chain saw for cutting plastic, masonry or non‑wood building materials. Use of the chain saw for operations different than intended could result in a hazardous situation.
l ) This chain saw is not intended for tree felling.
Use of the chain saw for operations different than intended could result in serious injury to the operator or bystanders.
m) Follow all instructions when clearing jammed material, storing or servicing the chain saw.
Make sure the switch is off and the battery pack is removed. Unexpected actuation of the chain saw while clearing the jammed material or servicing may result in serious personal 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 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 chain saw 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 chain saw 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 chain saw.
b ) Do not overreach and do not cut above shoulder height. This helps prevent unintended tip contact and enables better control of the chain saw 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 chain saw firmly with both hands when the motor is running. Use a firm grip with thumbs and fingers encircling the chain saw handles. Chain saw 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 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 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 bucking spikes into wood and allow chain to reach full speed before proceeding with 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 chain saw 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 chain saws.
• Low‑Kickback Chain, designed with a contoured depth gauge and guard link which deflect kickback force and allow 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 chain saw while 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 chain saw, make sure saw chain is not contacting any object.
• Do not operate a chain saw with one hand! Serious injury to the operator, helpers, or bystanders may result from one handed operation. A chain saw 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 chain saw before setting it down.
• Do not cut vines and/or small under brush.
• Use extreme caution when cutting small diameter branches because slender material may catch the saw chain and be whipped toward you or pull you off balance.

The charger then automatically switches to the pack charging mode. This feature ensures maximum battery pack life.
A cold battery pack may charge at a slower rate than a warm battery pack.
The hot/cold pack delay will be indicated by the red light(s) continuing to blink but with the yellow light continuously ON. Once the battery pack has reached an appropriate temperature, the yellow light will turn OFF and the charger will resume the charging procedure.

Fan-Cooled Chargers
Some chargers are 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
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 and the battery pack will need to be recharged.

Important Charging Notes

1. Longest life and best performance can be obtained if the battery pack is charged when the air temperature is between 65 °F – 75 °F (18 °C–24 °C). DO NOT charge when the battery pack is below 40 °F (4.5 °C), or above 104 °F (40 °C). This is important and will prevent serious damage to the battery pack.

2. The charger and battery pack may become warm to the touch while charging. This is a normal condition, and does not indicate a problem. To facilitate the cooling of the battery pack after use, avoid placing the charger or battery pack in a warm environment such as in a metal shed or an uninsulated trailer.

3. If the battery pack does not charge properly:
   a. Check operation of receptacle by plugging in a lamp or other appliance;
   b. Check to see if receptacle is connected to a light switch which turns power off when you turn out the lights;
   c. If charging problems persist, take the tool, battery pack and charger to your local service center.

4. You may charge a partially used pack whenever you desire with no adverse effect on the battery pack.

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.

Wall Mounting

Some DeWALT chargers are designed to be wall mountable or to sit upright on a table or work surface.

Common Cutting Techniques

This DCCS674 chainsaw is not intended to be used on the ground, therefore this manual does not contain instructions for felling trees, lambing and bucking trees.
For instructions on these techniques when using other DeWALT chainsaws refer to the instruction manuals for those DeWALT chainsaws. For a copy of those DeWALT chainsaw instruction manuals please contact DeWALT.
Call 1‑800‑4‑DeWALT (1‑800‑433‑9258) or visit our website: www.dewalt.com

WARNING: These in-tree instructions apply to DeWALT top-handle chainsaws, designed exclusively for in-tree cutting applications by certified tree service professionals specifically trained to do so in accordance with ANSI Z133 and TICA training materials.
WARNING: Blocking can result in injury. It should only be performed by a trained person.
WARNING: Recommended that first time users should practice cutting logs on a saw horse or log cradle.
WARNING: Do not work in trees with high wind conditions.
WARNING: Ensure all bystanders are clear of the fall area before starting operation.
WARNING: Always keep yourself and your equipment clear of the material being removed.
CAUTION: Be sure battery is fully charged before working in a tree.

Pruning

1. Make the first cut from the under of the limb, under buck (1/3 diameter) to avoid splintering as shown below.

2. Then make the second cut from the top of the limb, over buck (2/3 diameter), to meet 1st cut as shown below.
   NOTE: The limb will fall, ensure you are clear of it before completing the cut.

3. Make the finishing cut, flush against the main trunk as shown below.

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

Blocking

Removing sections from a standing tree
Before blocking is started have wedges (wood, plastic or aluminum) and a heavy mallet handy. Remove loose bark, nails, staples, and wire from the tree where the blocking cuts are to be made.

Conventional Notch

• Notching Undercut – Cut the notch 25% of the diameter of the tree block, perpendicular to the direction of the fall. Make the lower horizontal notching cut first as shown below. This will help to avoid pinching of either the saw chain or the guide bar when the second notch cut is being made. Consider conditions such as wind, tree lean, slope of the ground that could effect the direction of fall.
• Back Cut – Cut the back cut at the same level as the first horizontal notching cut. Keep the back cut parallel to the horizontal notching cut as shown below. Make the back cut so approximately 10% of the tree block remains to act as a hinge as shown below. The hinge wood keeps the tree block from falling in the wrong direction. Do not cut through the hinge.
• As the felling cut gets close to the hinge the tree block should begin to fall. If there is any chance that the tree block may not fall in the desired direction or it may rock back and bind the guide bar, stop cutting before the felling cut is complete and use wedges to open the cut and drop the tree block along the desired line of fall. When the tree block begins to fall remove the chain saw from the cut, release the trigger switch and activate the chain brake.

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 chainsaw 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 5/32″ (4 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 33 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. T.

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 racers (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. S.

5. Keep all cutter lengths equal as shown in Fig. U.

6. 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, use extra caution during this process.
