User manual MAKITA PS7300H

[. . . ] For the components listed under PARTS COVERED, the service dealer authorized by DOLMAR will, at no cost to you, make the necessary diagnosis, repair, or replacement necessary to ensure that the engine complies with applicable U. 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. [. . . ] 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 DOLMAR 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. Tighten all nuts, bolts and screws except the carburetor adjustment screws after each use. Keep spark plug and wire connection tight and clean. 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. Loosen the nuts (2) about one turn with the universal wrench. Raise the tip of the guide bar a little and turn the chain tensioning screw (13) to the right (clockwise) until the saw chain is again up against the bottom edge of the guide bar (see circle). While keeping the tip of the guide bar raised, tighten the nuts (2) again with the universal wrench. 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")! [. . . ] We therefore recommend that you consult a DOLMAR service center for all work not described in this instruction manual. The DOLMAR service centers have all the necessary equipment and skilled and experienced personnel, who can work out costeffective solutions and advise you in all matters. Please contact your nearest service center (list enclosed). Reliable long-term operation, as well as the safety of your chain saw, depend among other things on the quality of the spare parts used.
