User manual MCCULLOCH SET 700

[. . . ] Never use gasoline unless it is properly mixed with 2-cycle engine lubricant. DO NOT TOUCH or let your hands or body come in contact with a hot muffler or spark plug wire. Your unit comes with a spark arrester screen furnished in the user kit. Replacement spark arrester screen kits are available at your nearest McCulloch Authorized Service Center listed under "SAWS" in your Telephone Directory Yellow Pages. [. . . ] Connect the intermediate tube (H) and concentrator nozzle (I) or 56mm nozzle (J) (you can only use I nozzle at time). Push the tubes together and turn them clockwise so that they lock together (Fig. Use concentrator nozzle when you need more airflow in tight places: flower beds, under decks, etc. Use regular grade unleaded gasoline mixed with Genuine McCulloch 40:1 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 McCulloch 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. Place blower on your back by slipping arms through the shoulder straps as if you were putting on a jacket (Figure 3-4A). Once adjustments have been made, to the straps for user comfort, remove the blower from your back and place on level ground in an upright position. Some conventional gasolines are being blended with oxygenates such as alcohol or an ether compound to meet clean air standards. Because of flying debris, always wear American National Standards Institute approved shielded safety glasses or face shield when operating blower. To prevent serious injury, never perform maintenance or repairs with unit running. Before using your blower, review Safety Precautions in your User Manual, and all regulations for operation of the unit. DO NOT operate the blower with other people or animals in the immediate vicinity. Allow a minimum of 50 feet (15 meters) between operator and other people or animals. Use the blower for trees, shrubs, flower beds, and hard-to-clean areas. Use the unit around buildings and for other normal cleaning procedures. Stand away from the debris, at a distance that will easily allow you to control the direction of blown debris. To control velocity of airstream, blower can be operated at any speed between idle and full throttle. Experience with the unit will help you determine the amount of airflow necessary for each application. Operate power equipment only at reasonable hours-not early in the morning or late at night when people might be disturbed. [. . . ] Loosen knob (A) holding air filter cover in place, remove cover (B) and lift filter (C) from air box (Fig. 7-5B) for cleaning or replacement: make sure engine is off, spark plug is cool, then grasp spark plug boot firmly and remove from spark plug.
