General Chain Saw Safety Warnings

WARNING : Additional safety warnings for chainsaws.

• 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.
• 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.
• 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.
• 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 power tool “live” and could give the operator an electric shock.
• 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.
• Do not operate a chain saw in a tree, on a ladder, from a rooftop, or any unstable support. Operation of a chain saw in this manner could result in serious personal injury.
• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• Do not attempt to fell a tree until you have an understanding of the risks and how to avoid them. Serious injury could occur to the operator or bystanders while felling a tree.

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: 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.
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. Only use replacement bars and chains specified by the manufacturer. Incorrect replacement bars and chains may cause chain breakage and/or kickback.
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:

• 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.

• Do not over reach.

• Keep proper footing and balance at all times.

• Don’t let the nose of the guide bar contact a log, branch, ground or other obstruction.

• Don’t cut above shoulder height.

• Use devices such as low kickback chain and reduced kickback guide bars that reduce the risks associated with kickback.

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

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

• 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.

• 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.

• 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.
  Cut one log at a time.

• 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.

• Do not attempt plunge cuts or bore cuts.

• 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 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 chain saws. Low‑Kickback Chain, designed with a contoured depth gauge and guard link which deflect kickback force and allow the wood to gradually ride into the cutter. A low‑kickback chain is a chain which has met kickback performance requirements of ANSI B175.1–20

• Do not operate chain saw 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 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 size brush and saplings because slender material may catch the saw chain and be whipped toward you or pull you off balance

• NOTE: Saw chain tension should be adjusted regularly before each use.
• With the saw still on a firm surface check the saw chain 5 tension. The tension is correct when the saw chain snaps back after being pulled 1/4″ (6 mm) away from the guide bar 4 with light force from the middle finger and thumb    There should be no “sag” between the guide bar and the saw chain on the underside
• To adjust saw chain tension, loosen bar lock nuts 7 .
• Rotate the chain tension screw 8 located on the sprocket cover using the flat screwdriver end of the wrench 17 .
• Check saw chain tension, adjust if needed.
• Do not over‑tension the saw chain as this will lead to excessive wear and will reduce the life of the guide bar and saw chain.
• Once saw chain tension is correct, tighten bar lock nuts 7 until tight using 6 ft. lbs. (8 Nm) of torque.
• A new chain stretches slightly during the first few hours of use. It is important to check the tension frequently (after removing the battery packunplugging tool) during the first 2 hours of use.

Replacing the Saw Chain

• CAUTION : Sharp chain. Always wear protective gloves when handling the chain. The chain is sharp and can cut you when it is not running.
• WARNING : Sharp moving chain. To prevent accidental operation, ensure the battery is removed from the tool is unplugged before performing the following operations. Failure to do this could result in serious personal injury.
• To remove the saw chain 5 , place the saw on a flat, firm surface.
• Remove sprocket cover 6 as described in Installing the Guide Bar and Saw Chain section.
• Rotate the chain tension screw 8 using the flat screwdriver end of the wrench 17 . Turning the screw counterclockwise allows the guide bar 4 to recede and reduces the tension on the chain so that it may be removed.
• Wearing protective gloves, grasp the saw chain and lift the worn saw chain out of the groove in the guide bar.
• Flip guide bar over every time you replace the chain to ensure even wear.
• Place the new chain in the slot of the guide bar, making sure the saw teeth are facing the correct direction by matching the arrow and graphic of the saw chain on the sprocket cover 6

Follow instructions for Installing the Guide Bar and Saw Chain

• The replacement chain and bar are available from your nearest authorized service center.
• The DCCS672 chain saw requires a replacement 18″ (45 cm) chain DWO1DT618 and a replacement 18″ (45 cm) bar DWZCSB18.
• The DCCS677 chain saw requires a replacement 20″ (50 cm) chain DWO1DT620 and a replacement 20″ (50 cm) bar DWZCSB20

Auto Oiling System

This chainsaw is equipped with an auto oiling system that keeps the saw chain and guide bar constantly lubricated. The oil level indicator 9 shows the level of the oil in the chainsaw. If the oil level is less than a quarter full, remove the battery from the chainsaw and refill with the correct type of oil. Always empty oil tank when finished cutting. NOTE: Use a high-quality bar and chain oil for proper saw chain and bar lubrication. As a temporary substitute, a non‑detergent SAE30 weight motor oil can be used. The use of a vegetable- based bar and chain oil is recommended when pruning trees. Mineral oil is not recommended because it may harm trees. Never use waste oil or very thick oil. These may damage your chain saw.

Filling the Oil Reservoir

• Unscrew counterclockwise and then remove the oil cap 10 . Fill the reservoir with the recommended bar and chain oil until the oil level has reached the top of the oil level indicator 9 .
• Refit the oil cap and tighten clockwise.
• Periodically switch the chainsaw off and check the oil level indicator to ensure the bar and chain are being properly oiled.

Proper Hand Position

WARNING : To reduce the risk of serious personal injury, ALWAYS use proper hand position as shown.
WARNING : To reduce the risk of serious personal injury, ALWAYS hold securely in anticipation of a sudden reaction

Installing and Removing the Battery Pack

NOTE: For best results, make sure your battery pack is fully charged. To install the battery pack 15 into the tool handle, align the battery pack with the rails inside the tool’s handle and slide it into the handle until the battery pack is firmly seated in the tool and ensure that it does not disengage. To remove the battery pack from the tool, press the release button 16 and firmly pull the battery pack out of the tool handle. Insert it into the charger as described in the charger section of this manual.

Operating the Chain Saw

• WARNING: Read and understand all instructions. Failure to follow all instructions listed below may result in electric shock, fire and/or serious personal injury.
• Guard Against Kickback which can result in severe injury or death. See General Power Tool Safety Warnings and General Chainsaw Safety Warnings, and
• Causes and Operator Prevention of Kickback and Kickback Safety Features, to avoid the risk of kickback.
• Do not overreach. Do not cut above chest height. Make sure your footing is firm. Keep feet apart. Divide your weight evenly on both feet.
• Use a firm grip with your left hand on the front handle 13 and your right hand on the rear handle 12 so that your body is to the left of the guide bar.
• Do not hold chain saw by chain brake/front hand guard 3 . Keep elbow of left arm locked so that left arm is straight to withstand a kickback.
• WARNING: Never use a cross‑handed grip (left hand on the rear handle and right hand on the front handle).
• WARNING: Never allow any part of your body to be in line with the guide bar 4 when operating the chain saw.
• Never operate while in a tree, in any awkward position or on a ladder or other unstable surface. You may lose control of saw causing severe injury.
• Keep the chain saw running at full speed the entire time you are cutting.
• Allow the saw chain to cut for you. Exert only light pressure. Do not put pressure on chain saw at end of cut.
• WARNING: When not in use always have the chain brake engaged and battery removed.

Setting the Chain Brake

• Your chain saw is equipped with a chain braking system which will stop the chain quickly in case of kickback.
• Remove the battery from the tool.
• To engage the chain brake, push the chain brake/front hand guard 3 forward until it clicks into place.
• Pull the chain brake/front hand guard 3 towards the front handle 13 into the “set” position
• The tool is now ready to use.
• NOTE: In the event of kickback, your left hand will come in contact with the front guard, pushing it forward, toward the workpiece. This will stop the tool.

Testing the Chain Brake

• Test the chain brake before every use to make sure it operates correctly.
• Place the tool on a flat, firm surface. Make sure the saw chain 5 is clear of the ground.
• Grip the tool firmly with both hands and turn the chain saw on.
• Rotate your left hand forward around the front handle 13 so the back of your hand comes in contact with the chain brake/front hand guard 3 and push it forward, toward the workpiece. The saw chain should stop immediately.
• NOTE: If saw does not stop immediately, stop use of tool and bring it to an authorized service center nearest you.
• WARNING: Make sure to set chain brake before cutting.

ON/OFF Switch

• Always be sure of your footing and grip the chain saw firmly with both hands with the thumb and fingers encircling both handles.
• To turn the unit on, push down on the the lock off lever 2 , shown in Fig. J, and squeeze the trigger switch 1 . Once the unit is running, you may release the lock off lever.
• In order to keep the unit running you must continue to squeeze the trigger. To turn the unit off, release the trigger.
• NOTE: If too much force is applied while making a cut the saw will turn off. To restart saw, you must release the trigger switch 1 before the saw will restart.
• Begin your cut again this time with less force. Allow the saw to cut at its own pace

Common Cutting Techniques Felling

• The process of cutting down a tree. Do not fell trees in high wind conditions
• A retreat path should be planned and cleared as necessary before cuts are started.
• The retreat path should extend back and diagonally to the rear of the expected line of fall as shown below
• Before felling is started, consider the natural lean of the tree, the location of larger branches and the wind direction to judge which way the tree will fall. Have wedges (wood, plastic or aluminum) and a heavy mallet handy. Remove dirt, stones, loose bark, nails, staples, and wire from the tree where the felling cuts are to be made.
• Notching Undercut – Make the notch 1/3 of the diameter of the tree, perpendicular to the direction of the fall. Make the lower horizontal notching cut first.
• This will help to avoid pinching of either the saw chain or the guide bar when the second notch cut is being made as shown below.
• Felling Back Cut – Make the felling back cut at least 2″ (51 mm) higher than the horizontal notching cut. Keep the felling back cut parallel to the horizontal notching cut. Make the felling back cut so enough wood is left to act as a hinge. The hinge wood keeps the tree from twisting and falling in the wrong direction. Do not cut through the hinge as shown below.
• As the felling cut gets close to the hinge the tree should begin to fall. If there is any chance that the tree may not fall in the desired direction or it may rock back and bind the saw chain, stop cutting before the felling cut is complete and use wedges to open the cut and drop the tree along the desired line of fall.
• When the tree begins to fall remove the chainsaw from the cut, stop the motor, put the chainsaw down, then use the retreat path planned. Be alert for overhead limbs falling and watch your footing.

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 chainsaw as shown below. Trim limbs from opposite side keeping tree stem between you and saw. Never make cuts with saw between your legs or straddle the limb to be cut

Bucking

WARNING: Recommend that first time users should practice cutting on a saw 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.

• Always start a cut with the saw chain running at full speed.
• Place the bottom spike 21 of the chainsaw behind the area of the initial cut as shown below.
• Turn the chainsaw on then rotate the saw chain and bar down into the tree, using the spike as a hinge.
• Once the chainsaw gets to a 45 ° angle, level the chainsaw again and repeat steps until you cut fully through.
• 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 saw quickly.
• 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.
• 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
• 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 chain saw handles. Don’t let the chain contact the ground. After completing the cut, wait for the saw chain to stop before you move the chain saw. Always stop the motor before moving from cut to cut.
