5 Introduction Introduction Thank you for your purchase. The information contained in this manual will help you receive maximum performance and satisfaction from your trimmer and, if followed, reduce the risk of injury from its use. The terminology utilized in this manual when referring to the power tool reflects the type of cutting attachments that may be mounted on it. The term "trimmer" is used to designate an FS / FSA unit that is equipped with a nylon line head or a head with flexible plastic blades (i.e., the PolyCut head.) A "brushcutter" designates a unit equipped with a rigid metal blade. Many STIHL FS / FSA models, including the FSA 30, may be used as either a trimmer or a brushcutter. Therefore, the power tool is referred in this manual as a "trimmer / brushcutter." SAVE THIS MANUAL! Because a trimmer / brushcutter is a high-speed cutting tool, special safety precautions must be observed to reduce the risk of personal injury. Read this instruction manual thoroughly before use and periodically thereafter. Follow all safety precautions. Careless or improper use can cause serious or fatal injury. Have your authorized STIHL servicing dealer show you how to operate your power tool. Do not lend or rent the power tool without this instruction manual. Allow only persons who fully understand the information in this manual to operate the trimmer / brushcutter. For further information, or if you do not understand any of the instructions in this manual, please go to or contact your authorized STIHL servicing dealer. English As more fully explained later in this manual, to reduce the risk of personal injury, make sure your unit is equipped with the proper handle, harness and deflector for the type of cutting attachment you are using. Use only cutting attachments that are specifically authorized by STIHL for use with your FSA model. Always wear proper protective apparel and eye protection. Bystanders, especially children, and animals should not be allowed in the work area where the trimmer is in use. Use of this machine may be hazardous. If the rotating line or blade comes in contact with your body, it will cut you. When it comes in contact with solid foreign objects such as rocks, glass or bits of metal, it may fling them directly or by ricochet in the direction of bystanders or the operator. Striking such objects could damage the cutting attachment and may cause blades to crack, chip or break. Thrown objects, including broken heads or blades, may result in serious or fatal injury to the operator or bystanders. Follow the safety precautions in this manual to reduce the risk of personal injury. Guide to Using this Manual.

19 5 IMPORTANT SAFETY INSTRUCTIONS 5m (50ft) Inspect the work area. Remove stones, glass, rocks, pieces of metal or other objects that could be thrown by the cutting attachment, damage the cutting attachment or cause personal injury or damage to property (e.g., parked vehicles, windows). STIHL does not recommend the use of rigid blades when cutting in rocky areas or in areas where there is debris or other objects that could be thrown by the cutting attachment. Always wear proper eye protection and keep bystanders at least 50 ft. (5 m) away from the work area. Any persons who must enter the restricted area must also wear proper eye protection. To reduce the risk of damage to property, also maintain this distance from such objects as vehicles and windows. Maintaining a minimum distance of 50 ft. (5 m) cannot eliminate the potential risk of personal injury and property damage from thrown objects. Switch off the motor immediately if you are approached while working with the trimmer / brushcutter. Your trimmer / brushcutter is equipped with a deflector. To reduce the risk of personal injury from thrown objects and contact with the cutting attachment: Never operate the trimmer / brushcutter with a damaged or missing deflector. The cutting attachment and deflector must be an approved combination. Keep the deflector properly adjusted at all times. English Use of wire, metal-reinforced line or other non-approved cutting attachments is not authorized and could be extremely dangerous. Never use wire or metal-reinforced line on this trimmer / brushcutter. Use only the cutting attachments recommended in this manual, in combination with the recommended deflector. See Combinations of Deflectors and Cutting 5. To reduce the risk of severe personal injuries from unintentional starting: Never touch the cutting attachment or mowing head with your hand, feet or any other part of your body while the power tool is connected to a battery, even when the cutting attachment is not moving. Keep bystanders at least 50 ft. (5 m) away. If the cutting attachment or deflector becomes dirty, clogged or stuck, always switch off the motor, make sure the cutting attachment has stopped and remove the connecting cord from the trimmer / brushcutter before inspecting the cutting attachment and deflector. Clean dirt, grass, weeds and other material from the mowing head or blade and deflector at regular intervals, but only after unplugging the connecting cord. A damaged or loose cutting attachment may vibrate, crack, break or come off during operation, which may result in serious or fatal injury. Make sure the cutting attachment is properly tightened before starting work. Check the tightness and condition of the cutting attachment before starting work and any time cutting behavior changes during use. Always switch off the motor, wait for the cutting attachment to stop and remove the connecting cord before inspecting the trimmer / brushcutter, its cutting attachment or battery B 7

20 English If the cutting attachment loosens after being properly tightened, stop work immediately and have the unit inspected by your authorized STIHL servicing dealer. A cracked, damaged or worn out cutting attachment may shatter at high speeds and cause serious or fatal injury. Replace a cracked, damaged or worn out mowing head or a cracked, bent, warped, damaged, dull or worn out blade immediately, even if damage appears to be limited to superficial cracks. Never use a trimmer / brushcutter with a loose or damaged cutting attachment. DANGER To reduce risk of electrocution: Never operate this trimmer in the vicinity of any wires or cables that may be carrying electric current. Do not rely on the trimmer's insulation against electric shock. 5.8 Working with the Cutting Attachments 5.8. Kickout (Blade Thrust) with All Metal Cutting Attachments 0000-GXX-305-A 5 IMPORTANT SAFETY INSTRUCTIONS Kickout (blade thrust) is the sudden and uncontrolled movement of the cutting head toward the operator's right or rear that can occur when the shaded areas (especially the darkly shaded area) of a rotating blade contact a solid rigid object like a tree, rock, bush or wall. The cutting attachment may be thrown to the right or to the rear (black arrow) any time the rapid rotation of the blade is stopped, slowed, snagged or bound in an object that it doesn't immediately cut. This kickout (blade thrust) may cause loss of control and may result in serious or fatal injury to the operator or bystanders. To reduce the risk of injury, extreme caution should be used when cutting with the shaded area of any rigid blade. The greater the force of the kickout reaction, the more difficult it becomes for the operator to control the unit. Blade thrust is more likely to occur in areas where it is difficult to see the material being cut. Many factors influence the occurrence and force of the kickout reaction. These include cutting attachment speed, the speed at which the cutting attachment contacts the object, the location and angle of contact, the condition of the cutting attachment, and how quickly the cutting attachment is slowed, snagged or stopped, among other factors. Use caution when working with the shaded areas of any metal cutting attachment. To reduce the risk of personal injury from kickout and blade thrust when using a rigid cutting attachment: Avoid cutting close to fences, sides of buildings, tree trunks or other such objects when a metal cutting blade is mounted. STIHL recommends using a nylon line head for such jobs. Keep metal cutting attachments sharp. Keep bystanders at least 50 ft. (5 m) away from the work area B

21 5 IMPORTANT SAFETY INSTRUCTIONS 5.8. Using a Mowing Head English Take care to clear area of all objects and debris before trimming along fences or walls, near tree trunks or other objects that could increase the possibility of injury from the ricochet of thrown objects Using a Grass Cutting Blade 0000-GXX-3800-A0 When working, sweep the trimmer in a controlled manner, parallel to the ground in front of you. Mowing heads are to be used only on units equipped with a line-limiting blade in the deflector in order to keep the line at the proper length. When trimming along a fence, wall or around trees, it is preferable to use a mowing head with nylon line to reduce the risk of blade thrust or kickout, damage to the cutting attachment, and to reduce damage to the fence, wall or trees. To reduce the risk of serious injury: Never use wire or metal-reinforced line or other material in place of the recommended nylon cutting line. Pieces of wire could break off and be thrown at high speed toward the operator or bystanders. A cracked, damaged or worn out mowing head may shatter at high speeds and cause serious or fatal injury. Have a cracked, damaged or worn out mowing head replaced immediately, even if damage appears to be limited to superficial cracks. When working close to fences, sides of buildings, tree trunks of other such objects, be alert to an increased possibility of ricochets. When working with a grass cutting blade, sweep the trimmer in a controlled manner, parallel to the ground in front of you. To reduce the risk of kickout, use the left side of the cutting blade. All kinds of grass and weeds can be cut with a grass cutting blade. The 4-tooth grass cutting blade is intended to cut grass and weeds. It has 4 cutting knives with cutting edges on both sides, i.e., front and rear. When the cutting edges on one side become dull, the blade can be turned over to utilize the cutting edges on the other side. The 8-tooth grass cutting blade is recommended for cutting fern or similar fleshy vegetation. When the cutting edges on one side become dull, the cutting edges have to be resharpened. The blade cannot be turned over to utilize the cutting edges on the other side GXX-380-A B 9
