Stihl SR 320 Instruction Manual - Page 9

Never insert any foreign object into the air intake of the machine or into the nozzle of the mistblower. It wil damage the fan wheel and may cause serious injury to the operator or bystanders as a result of the object or broken parts being thrown out at high speed. Do not place the mistblower on the ground when operating at high speed, because small objects such as sand, gras, dust, etc. may be pulled into the air intake and damage the fan wheel. In the event of the machine catching fire (for what ever reason) throw it off quickly by releasing the spring catches on both sides of the harness. In an emergency, you may slip out of the harness and throw off the machine quickly by first releasing the lap belt on machines that are so equipped and then lifting the tabs of the two sliding harness adjusters to slacken the shoulder straps. Try this procedure a number of times before using the machine in order to become accustomed with it. Pay attention to the direction of the wind, i.e., do not work against the wind. To reduce the risk of stumbling and loss of control, do not walk backward while operating the machine. Pay attention to the direction of the wind, i.e. do not work against the wind. Do not direct air blast towards bystanders. When spraying, stand so that the wind blows the spray away from you and bystanders. Keep children and pets away from areas that have just been sprayed. The mistblower may be used only for the operations described in your manual. Exercise extreme caution when handling chemicals. Follow all safety precautions and instructions laid down by the manufacturer. Avoid contact with chemicals and chemical solutions. Be sure the mistblower is the proper tool for the job. Always empty and clean the liquid container after each use. Residual chemicals may have undesirable effects during subsequent spraying with a different type of chemical (e.g., residual herbicide may damage or kill plants being sprayed with a pesticide). It is best to fill the container with clean water and let it drain out with the tap open. Be cautious where you drain the liquid during the cleaning process. Never store liquid in the container for more than one day. Do not spray flammable liquids; such as gasoline or paint thinner. Such substances create a risk of fire or explosion and may damage the mistblower. Do not spray caustic or acid solutions. Contact with such substances may cause serious or fatal injury or damage the property, including the mistblower. The mistblower can be used for spraying chemicals an liquids to control pests and weeds in fruit and vegetables gardens, on trees and bushes, citrus, coffee, tobacco, cotton and many other areas. It is also useful in the maintenance of young trees, controlling the bark beetle and other plant diseases.
