Mixing Filling Fuel CAUT|ON! Some types of gasoline contain alcohol as an oxygenate. Oxygenated gasoline may cause increased operating temperatures. Under certain conditions, alcohol-based gasoline may also reduce the lubricating qualities of some 2-cycle mixing oils. Never use any type of gasoline containing more than 10% alcohol by volume! Generic oils and some outboard oils may not be intended for use in high-performance engines, and should never be used in your Swisher engine. CAUTION! This engine is designed to operate on a 50:1 mixture consisting of unleaded gasoline and ISO-L-EGD or JASO FC class 2-cycle mixing oil only. Use of non-approved mixing oils can lead to excessive carbon deposits. m Use only fresh, clean unleaded gasoline with a pump octane of 87 or higher. m Mix all fuel with a 2-cycle air-cooled mixing oil that meets or exceeds ISO-L-EGD and/or JASO FC classified oils at 50:1 gasoline/oil ratio. Examples of 50:1 mixing quantities m I gallon of gasoline to 2.6 oz. mixing oil _ the Fuel Tank WARNING! Minimize the Risk of Fire NEVER smoke or light fires near the engine. ALWAYS stop the engine and allow it to cool before refueling. Avoid overfilling and wipe off any fuel that may have spilled. ALWAYS inspect the unit for fuel leaks before each use. During each refill, check that no fuel leaks from around the fuel cap and/or fuel tank. If fuel leaks are evident, stop using the unit immediately. Fuel leaks must be repaired before using the unit. m 5 liters of gasoline to 100ml. mixing oil Mix only enough fuel for your immediate needs! If fuel must be stored longer than 30 days and Swisher E4 engine oil with fuel stabilizer is not used, it should first be treated with a fuel stabilizer such as STA-BIL TM . Swisher E4 engine oil is a registered JASO FC classified oil and also meets or exceeds ISO-L-EGD performance requirements. Swisher E4 engine oil is recommended for use in all Swisher low emissions engines and also includes a fuel stabilizer. ALWAYS move the unit at least 10 feet (3 meters) away from a fuel storage area or other readily flammable materials before starting the engine.

Figure 10 Figure 18 Starting the Engine (continued) When the Engine Starts... _ WARN|NG! ,_ The cutting attachment may rotate when the engine is started! WARN|NG! Never start the engine from the operating position. 6. When the engine starts, slowly move the choke lever to the "OPEN" position. See Figure 20. (If the engine stops after the initial start, close the choke and restart.) 7. Operating the throttle will automatically disengage the fast idle setting. If the engine fails to start after several attempts with the choke in the closed position, the engine may be flooded with fuel. If flooding is suspected, move the choke lever to the open position and repeatedly pull the recoil starter to remove excess fuel and start the engine. If the engine still fails to start, refer to the troubleshooting section of this manual. II After the engine starts, allow the engine to warm up at idle 2 or 3 minutes before operating the unit. m After the engine is warm, pick up the unit and clip on the shoulder strap. See page 12. m Advancing the throttle makes the cutting attachment turn faster; releasing the throttle permits the attachment to stop turning. If the cutting attachment continues to rotate when the engine returns to idle, carburetor idle speed should be adjusted (see "Adjusting Engine Idle" below). Open Figure 20 Idle the engine briefly before stopping (about 2 minutes), then slide the ignition switch to the "O" (Engine OFF) position. Figure 21 Adjusting Engine |die / The engine must return to idle speed whenever the throttle lever is released. Idle speed is adjustable, and must be set low enough to permit the engine clutch to disengage the cutting attachment. Idle Speed Adjustment _ Fi WARN|N6! The cutting attachment must NEVER rotate at engine idle! If the idle speed cannot be adjusted by the procedure described here, contact Swisher Inc. at (800) 222-8183, or go to www.swisher. corn for assistance. 1. Place the trimmer on the ground, then start the engine, and then allow it to idle 2-3 minutes until warm. 2. If the attachment rotates when the engine is at idle, reduce the idle speed by turning the idle adjustment screw counter-clockwise. See Figure 22. 3. If a tachometer is available, the engine idle speed should be finaJ adjusted to 3,000 (_+300)RPM (min-1). 4. Carburetor fuel mixture adjustments are preset at factory and cannot be serviced in the field. 11 Checking Unit Condition NEVER operate the unit with the cutting attachment shield or other protective devices removed! _ WARN|NG! A cutting attachment shield or other protective device is no guarantee of protection against ricochet. YOU MUST ALWAYS GUARD AGAINST FLYING DEBRIS! ALWAYS make sure the cutting attachment is properly installed and firmly tightened before operation. NEVER use a cracked or warped cutting attachment: replace it with a serviceable one. ALWAYS make sure the cutting attachment fits properly into the appropriate attachment holder. If a properly installed attachment vibrates, replace the attachment with new one and re-check. ALWAYS stop the engine immediately and check for damage if you strike a foreign object or if the unit becomes tangled. Do not operate with broken or damaged equipment, NEVER allow the engine to run at high RPM without a load. Doing so could damage the engine. NEVER operate a unit with worn or damaged fasteners or attachment holders. Use only authorized Swisher parts and accessories with your Swisher trimmer.

Additional hardware may be required to mount the Fixed Line or the Flail type trimmer heads. 12 Trimming and Mowing Grass 24 CAUTION! Operation at low RPM can lead to premature clutch failure, Hold the trimmer so the trimmer head is angled slightly into the area to be cut. To ensure maximum trimmer-line service life, cut only with the tip of the trimmer line. Cut grass by swinging the trimmer from left to right. Keep the trimmer head horizontal. See Figure 24. Edging Tilt the handle about 100 ° to the left (from horizontal) and move forward, holding the trimmer vertically as shown in Figure 25. ,X Using a Blade E4-B4000 WARN|NG! m Before working with a bladeequipped unit, always inspect and clean the area of objects that could interfere with or damage the blade. m Never use a blade near sidewalks, fence posts, buildings or other objects that could cause injury or damage. II Never use a blade for purposes other than those for which it was designed. m Whenever you strike a hard object with a blade, always stop the brushcutter and carefully inspect the blade for damage. NEVER OPERATE THE BRUSHCUTTER WITH A DAMAGED BLADE! II A blade-equipped unit must be equipped with a bicycle-type handlebar or barrier bar as well as a harness or shoulder strap. II Always make sure the cutting attachment shield is properly installed before operating this unit. Operating Units with Blade Thrust Engine Operating 'Blade thrust' is a sudden sideways or backward motion of the brushcutter. Such motion may occur when the blade jams or catches on an object such as a sapling tree or tree stump. BE CONSTANTLY ALERT FOR BLADE THRUS_F AND GUARD AGAINST ITS EFFECTS! Operate the unit at full throttle while cutting. Best fuel efficiency is obtained by releasing the throttle when swinging back after a cut. Brushcutter II Avoid operating the engine at low speeds. Doing so can lead to rapid clutch weal: In addition, slow-speed operation tends to cause grass and debris to wrap around the cutting head. Brushcutter II To prevent possible engine damage, do not allow the brushcutter to run at high speeds without a load. Shoulder Strap A shoulder strap provides additional protection against blade thrust. In addition, a shoulder strap gives significant support and comfort to help ensure safe and efficient operation. When operating a E4-B4000 with a blade, make sure both the handle and shoulder strap are adjusted to the size of the operator using the unit. a Blade The blade rotates counter-clockwise. For best performance and to minimize being stuck by debris, move the blade from right to left while advancing on your work. Position the blade so cuts are made between the blade's 8 o'clock and 10 o'clock positions (as viewed from above). DO NOT cut between the 10 o'clock and 5 o'clock )ositions. ,i_ Handlebar A brushcutter handlebar or barrier bar helps prevent the operator from moving forward, or the unit moving rearward, thus preventing inadvertent bodily contact with the blade. ALWAYS KEEP THE HANDLEBAR OR BARRIER BAR SECURELY IN PLACE ON THE UNIT! Speeds Cut on the left side of the blade. KEEP YOUR BODY OUTSIDE THE PATH OF BLADE ROTATION OK To Cut WARN|NG! When cutting wood with a saw, feed the blade slowly--never strike or "slam" a spinning blade against the wood, Figure Vertical &WARNING! DO NOT use 2-tooth or non-Swisher approved 4-tooth cutting blades with Swisher trimmers and brushcutters. O_lock 26 Cuts Hold the brushcutter with the blade at a 90 ° angle to the ground so the blade's bottom edge rotates toward the operato]: Move the blade from top to bottom through the cut, and cut only with the bottom edge of the blade. & Figure 27 WARN|NG! When making vertical cuts, never allow the blade to exceed waist height, 13 General Maintenance MAINTENANCE, REPLACEMENT OR REPAIR OF EMISSION CONTROL DEVICES AND SYSTEMS MAY BE PERFORMED BY ANY REPAIR ESTABLISHMENT OR INDIVIDUAL; HOWEVER, WARRANTY REPAIRS MUST BE PERFORMED BYA DEALER OR SERVICE CENTER AUTHORIZED BY SWISHER. THE USE OF PARTS THATARE NOT EQUIVALENT IN PERFORMANCE AND DURABILITY TO AUTHORIZED PARTS MAY IMPAIR THE EFFECTIVENESS OF THE EMISSION CONTROL SYSTEM AND MAY HAVEA BEARING ON THE OUTCOME OF A WARRANTY CLAIM. _ WARN|NG! Before performing any maintenance, repair or cleaning work on the unit, make sure the engine and cutting attachment are completely stopped. Disconnect the spark plug wire before performing service or maintenance work. _ WARN|NG! Non-standard parts may not operate properly with your unit and may cause damage and lead to personal injury. Using non-standard replacement parts could invalidate your Swisher warranty. Muffler This unit must never be operated with a faulty or missing spark arrester or muffler. Make sure the muffler is well secured and in good condition. A worn or damaged muffler is a fire hazard and may also cause hearing loss. Spark Plug Keep the spark plug and wire connections tight and clean. Fasteners Make sure nuts, bolts, and screws (except carburetor adjusting screws) are tight. Air Filter The E4 engine that powers your Swisher model is a hybrid 4-stroke engine. As a hybrid, the engine is lubricated by oil mixed with the gasoline and air from the carburetor that moves through and around the internal parts of the engine in a similar way that a 2-stroke engine is lubricated. Without the heavy duty 2-stage air filter equipped on all E4 engines, dust and dirt could also move through the engine, decreasing engine life,increasing valve wear and the need for more frequent valve adjustments. To keep your E4 engine strong and reliable, Swisher recommends that you check and service the air filter as instructed in the 10-Hour Maintenance section that follows. Blades Keep blades sharp and check blade condition frequently. If a blade's performance changes suddenly, stop the engine and check the blade for cracks or other damage. Replace a damaged blade IMMEDIATELY! Daily _ II WARN|N6! Never repair a damaged blade by welding, straightening, or by modifying its shape, An altered blade may break during operation, resulting in serious personal injury, II Blades are not interchangeable between Swisher edgers and trimmer/ brushcutter models. Operating any unit with a blade or attachment not approved for that unit can be hazardous and may cause serious injury. Maintenance Prior to each work following: day, perform the II Remove dirt or debris from the engine, check the cooling fins and air cleaner for clogging and clean them as necessary. I O-Hour Carefully remove any accumulation of dirt or debris from the muffler or the fuel tank. Dirt build-up in these areas could cause engine overheating, induce premature wear, or create a fire hazard. m Check for loose or missing screws or components.
