WARNING: Never turn saw upside down to undercut. The saw cannot be controlled in this position. SecondcutFirstcutonpressuresideoflog Second cut First cut on pressure side of log BUCKING WITHOUT A SUPPORT S Overcut through 1/3 of the diameter of the log. S Roll the log over and finish with a second overcut. S Give special attention to logs under strain to prevent the saw from pinching. Make the first cut on the pressure side to relieve the stress on the log. BUCKING USING A LOG OR SUPPORT STAND S Remember your first cut is always on the pressure side of the log. S Your first cut should extend 1/3 of the diameter of the log. S Finish with your second cut.

Do not allow the moving chain to contact any other branched or objects at the nose of the guide bar when limbing or pruning. Allowing such contact can result in serious injury. WARNING: Neverclimbintoa tree to limb or prune. Do not stand on ladders, platforms, a log, or in any position which can cause you to lose your balance or control of the saw. IMPORTANT POINTS S Watch out for springpoles. Use extreme caution when cutting small size limbs. Slender material may catch the saw chain and be whipped toward you or pull you off balance. S Be alert for springback. Watch out for branches that are bent or under pressure. Avoid being struck by the branch or the saw when the tension in the wood fibers is released. S Keep a clear work area. Frequently clear branches out of the way to avoid tripping over them. LIMBING S Always limb a tree after it is cut down. Only then can limbing be done safely and properly. S Leave the larger limbs underneath the felled tree to support the tree as you work. S Start at base of the felled tree and work toward the top, cutting branches and limbs. Remove small limbs with one cut. S Keep the tree between you and the chain as much as possible. S Remove larger, supporting branches with the cutting techniques described in BUCKING WITHOUT A SUPPORT. S Always use an overcut to cut small and freely hanging limbs. Undercutting could cause limbs to fall and pinch saw. PRUNING WARNING: Limit pruning to limbs shoulder height or below. Do not cut if branches are higher than your shoulder. Get a professional to do the job. S Make your fist cut 1/3 of the way through the bottom of the limb. S Next make a 2nd cut all the way through the limb. Then cut a third overcut leaving a 1 to 2 inch collar from the trunk of the tree.

Cleaning the air filter: A dirty air filter decreases engine performance and increases fuel consumption and harmful emissions. Always clean after every 5 hours of operation. 1. Clean the cover and the area around it to keep dirt and sawdust from falling into the carburetor chamber when the cover is removed. 2. Remove the parts as illustrated below. 3. Wash the filter in soap and water. Rinse in clean cool water. Air dry completely before reinstalling. 4.

A worn bar will damage your chain and make cutting difficult. After each use, ensure ON/STOP switch is in the STOP position, then clean all sawdust from the guide bar and sprocket hole. To maintain guide bar: S Move ON/STOP switch to the STOP posi tion. S Loosen and remove chain brake nuts and chain brake. Remove bar and chain from saw.
