[. . . ] USER MANUAL STOP ARRÊT ALTO For problems or questions, DO NOT return this product to the store. For your own safety, please read and follow the safety precautions in this manual before attempting to operate your chain saw. pN 9096-MD0707 Printed in Taiwan INTRODUCTION PLEASE READ Dear Customer , Thank you for purchasing a McCulloch product. With proper operation and maintenance, it will provide you with years of service. [. . . ] Chain has proper tension when it has a snug fit all around and can be pulled around by gloved hand. NOTE: If chain is difficult to rotate on guide bar or if it binds, too much tension has been applied. Decrease tension by turning the bar adjustment screw COUNTERCLOCKWISE slowly. When saw chain has proper tension, hold nose of bar in uppermost position and tighten the bar retaining nut securely. CHAIN BRAKE® MECHANICAL TEST Your chain saw is equipped with a CHAIN BRAKE® that reduces possibility of injury due to kickback. The brake is activated if pressure is applied against brake lever when, as in the event of kickback, operator’s hand strikes the lever. A WARNING The purpose of the CHAIN BRAKE® is to reduce the possibility of injury due to kickback; however, it cannot provide the intended measure of protection if the saw is operated carelessly. Always test the CHAIN BRAKE® before using your saw and periodically while on the job. 3-5B 3-3F B D D 3-4A C 3-3G 8 9 4 - FUEL AND LUBRICATION 4-1. FUEL Use regular grade unleaded gasoline mixed with Genuine Factory Parts 40:1 custom 2-cycle engine oil for best results. This will cause permanent engine damage and void the manufacturer’s warranty for that product. If 2-cycle lubricant other than Genuine Factory Parts Custom Lubricant is to be used, it must be a premium grade oil for 2-cycle air cooled engines mixed at a 40:1 ratio. Do not use any 2-cycle oil product with a recommended mixing ratio of 100:1. If insufficient lubrication is the cause of engine damage, it voids the manufacturer’s engine warranty for that occurrence. ENGINE PRE-START CHECKS FUEL MIXING TABLE WARNING Never start or operate the saw unless the bar and chain are properly installed. Be certain the CHAIN BRAKE® is disengaged (C) before starting unit (Figure 5-1A). - If unit does not Idle after restarting 2 times, follow these steps to adjust idle. Using a Phillips or slotted screwdriver - turn screw 1/4 to 1/2 turn clockwise (to the right). (Figure 5-2H) NOTE: If chain turns while idling - turn screw back to the left until chain stops and unit continues to idle. RECOMMENDED FUELS Some conventional gasolines are being blended with oxygenates such as alcohol or an ether compound to meet clean air standards. Your McCulloch engine is designed to operate satisfactorily on any gasoline intended for automotive use including oxygenated gasolines. MIXING FUEL Mix fuel with Genuine Factory Parts brand 2 cycle oil in an approved container. [. . . ] Lubrication of the sprocket tip is recommended after 10 hours of use or once a week, which ever occurs first. TOOLS FOR LUBRICATION: The Lube Gun (optional) is recommended for applying grease to the guide bar sprocket tip. The Lube Gun is equipped with a needle nose tip which is necessary for the efficient application of grease to the sprocket tip. CHAIN MAINTENANCE CHAIN TENSION: Check the chain tension frequently and adjust as often as necessary to keep the chain snug on the bar, but loose enough to be pulled around by hand. [. . . ]
