Pinch-Kickbackcan occur when thethe wood closes in and pinches themoving saw chain in the cut alongthe top of the guide bar and the sawchain is suddenly stopped. This sudden stopping of the chain results in areversal of the chain force used tocut wood and causes the saw tomove in the opposite direction of thechain rotation. The saw is drivenstraight back toward the operator. Pull-In can occur when the movingchain contacts a foreign object in thewood in the cut along the bottom ofthe guide bar and the saw chain issuddenly stopped. This sudden stopping pulls the saw forward and awayfrom the operator and could easilycause the operator to lose control ofthe saw.REDUCE THE CHANCE OFKICKBACK Recognize that kickback can happen.With a basic understanding of kickback, you can reduce the element ofsurprise which contributes to accidents. Never let the moving chain contactany object at the tip of the guide bar.

With a broken brakeband, the chain brake will not stop thechain. The chain brake must be replacedif any part is worn to less than 0.020 inch(0.5 mm) thick. Repairs on a chain brakeshould be made by your Sears ServiceCentre. Take your unit to the place of purchase or to the nearest Sears ServiceCentre. This saw is equipped with a chainbrake. The brake is designed to stopthe chain if kickback occurs. The inertia-activatedchain brake is ac vated if the front hand guard is pushedforward, either manually (by hand) orautoma%ally (by sudden movement). If the brake is already activated, it isdisengaged by pulling the front handguard back toward the front handle asfar as possible. When cutting with the saw, the chainbrake must be disengaged.DisengagedBraking function controlCAUTION:The chain brake must bechecked several times daily. The enginemust be running when performing thisprocedure. This is the only instancewhen the saw should be placed on theground with the engine running.10
Place the saw on firm ground. Grip theroar handle with your right hand and thefront handle with your left hand. Apply fullthrottle by fully depressing the throttle trigger. Activate the chain brake by turningyour left wrist against the hand guardwithout releasing your grip around thefront handle. The chain should stop immediately.Inertia activating function controlWARNING:When performing thefollowing procedure, the engine mustbe turned off.Grip the rear handle with your right handand the front handle with your left hand.Hold the chain saw approximately14inches (35 cm) above a stump or otherwooden surface. Release your grip onthe front handle and use the weight ofthe saw to let the tip of the guide barfall forward and contact the stump.When the tip of the bar hits the stump,the brake should activate.OPERATING TIPS Check chain tension before first useand after 1 minute of operation. SeeCHAIN TENSION in the MAINTENANCEsection. Cut wood only. Do not cut metal,plastics, masonry, non-wood buildingmaterials, etc. Stop the saw if the chain strikes aforeign object. Inspect the saw andrepair parts as necessary. Keep the chain out of dirt and sand.Even a small amount of dirt willquickly dull a chain and increase thepossibility of kickback. Practice cutting a few small logs using the following steps. This will helpyou get the "feel" of using your sawbefore you begin a major sawing operation. Squeeze the throttle trigger and allow the engine to reach full speedbefore cutting. Begin cutting with the saw frameagainst the log. Keep the engine at full speed theentire time you are cutting. Allow the chain to cut for you. Exertonly light downward pressure. Release the throttle trigger as soonas the cut is completed, allowingthe engine to idle. If you run thesaw at full throttle without a cuttingload, unnecessary wear can occur. To avoid losing control when cut iscomplete, do not put pressure onsaw at end of cut. Stop engine before setting saw down.TREE FELLING TECHNIQUESWARNING:Check for broken ordead branches which can fall whilecutting causing serious injury. Do notcut near buildings or electrical wires ifyou do not know the direction of treefall, nor cut at night since you will notbe able to see well, nor during badweather such as rain, snow, or strongwinds, etc. Carefully plan your sawing operationin advance. Clear the work area. You need aclear area all around the tree so youcan have secure footing. The chain saw operator should keepon the uphill side of the terrain as thetree is likely to roll or slide downhillafter it is felled. Study the natural conditions that cancause the tree to fall in a particulardirection. These conditions include: The wind direction and speed. The lean of the tree. The lean of atree might not be apparent due touneven or sloping terrain. Use aplumb or level to determine the direction of tree lean. Weight and branches on one side. Surrounding trees and obstacles. Look for decay and rot. If the trunk isrotted, it can snap and fall toward theoperator. Make sure there is enough room forthe tree to fall. Maintain a distance of24/2 tree lengths from the nearestperson or other objects. Enginenoise can drown out a warning call. Remove dirt, stones, loose bark,nails, staples, and wire from the treewhere cuts are to be made.Plan a clear retreat pathK11--(o-- -Direction of Fall
FELLING LARGE TREES(6 inches in diameter or larger)The notch method is used to fell largetrees. A notch is cut on the side of thetree in the desired direction of fall. Aftera felling cut is made on the oppositeside of tree, the tree will tend to fall inthe direction of the notch.NOTE: If tree has large buttress roots,remove them before making the notch.If using saw to remove buttress roots,keep saw chain from contactingground to prevent dulling of the chain.NOTCH CUT AND FELLING TREE Make notch cut by cutting the top ofthe notch first. Cut through 1/3 of thediameter of the tree. Next completethe notch by cutting the bottom. Seeillustration. Once the notch is cut, remove the wedge of wood from tree.Fellingcut hereFirst cut 'i After removing the wood, make thefelling cut on the opposite side of thenotch. This is done by making a cutabout two inches higher than thecenter of the notch. This will leaveenough uncut wood between the felling cut and the notch to form a hinge.This hinge will help prevent the treefrom falling in the wrong direction.Hinge holds tree onstump and helpsOpening offelling cutClosingof notchNOTE: Before felling cut is complete,use wedges to open the cut whennecessary to control the direction offall. To avoid kickback and chaindamage, use wood or plastic wedges,but never steel or iron wedges. Be alert to signs tha
the engine. Never try to start the saw when the guide bar is in a cut. Do not put pressure on the saw, es-pecially at the end of the cut. Doing so can cause you to lose control when the cut is completed. Stop engine before setting saw down. Hand carry saw only when engine is stopped. Carry with muffler away from body; guide bar .
