EMISSION COMPONENT DEFECT WARRANTY PERIOD The warranty period for this engine begins on the date of sale to the initial purchaser and continues for a period of 2 years. PARTS COVERED Listed below are the parts covered by the Emission Components Defect Warranty. Some of the parts listed below may require scheduled maintenance and are warranted up to the first scheduled replacement point for that part. [. . . ] The limbs could spring back toward the operator and cause loss of control of the saw or injury to the operator. Never operate a chain saw that is damaged, improperly adjusted or not completely or securely assembled. Follow the maintenance and repair instructions in the appropriate section of this manual. Always stop the engine and make sure that the chain is stopped before commencing any maintenance or repair work or cleaning the saw. Do not attempt any maintenance or repair work not described in this manual. Have such work performed by your MAKITA service shop only. Keep the chain, bar and sprocket clean and lubricated; replace worn sprockets or chains. Logs under strain require special attention to prevent the saw from pinching. The first cut is made on the compression side to relieve the stress on the log (see fig. If the saw pinches, stop the engine and remove it from the log. You can spot a dull chain when easy-to-cut wood becomes hard to cut and burn marks appear on the wood. The tension of the chain is correct if the chain rests against the bottom side of the guide bar and can still be easily turned by hand. While doing so the chain brake must be released. Check the chain tension frequently - new chains tend to get longer during use!When checking the chain tension the engine must be switched off. nOTE: It is recommended to use 2-3 chains alternatively. In order to guarantee uniform wear of the guide bar the bar should be turned over whenever replacing the chain. If kickback occurs due to contact of the guide-bar tip with wood (see SAFETY PRECAUTIONS, page 10), the chain brake will stop the chain through inertia if the kickback is sufficiently strong. the chain will stop within a fraction of a second. The chain brake is installed to block the saw chain before starting it and to stop it immediately in case of an emergency. IMPORTANT: NEVER run the saw with the chain brake activated (except for testing, see "Testing chain brake")!Doing so can very quickly cause extensive engine damage!
