OIL & FUEL INFORMATION RECOMMENDED OIL TYPE It is extremely important to use the proper type and weight of oil in the crankcase. Check the oil before each use and change the oil regularly. The use of incorrect or dirty oil can cause premature engine wear and failure. Use a high-quality SAE 30 weight oil of API (American Petroleum Institute) service class SF, SG, SH. FIGURE 3 ADDING OIL TO CRANKCASE: INITIAL USE NOTE: This unit is shipped without oil.
OIL & FUEL INFORMATION DEFINITION OF BLENDED FUELS 1. Remove the fuel cap and. Today's fuels are often a blend of petrol and oxygenates such as ethanol, methanol or MTBE (ether). Alcohol-blended fuel absorbs water. As little as 1% water in the fuel can make fuel form acids when stored. When using alcohol-blended fuel, use fresh fuel that is less than 60 days old. NOTE: Fill or add fuel to the tank only when the trimmer is in a horizontal position. Using Blended Fuels 2.
STARTING/STOPPING INSTRUCTIONS STARTING INSTRUCTIONS WARNING: Operate this unit only in a well ventilated outdoor area. Carbon monoxide exhaust fumes can be lethal in a confined area. Start/On WARNING: Avoid accidental starting. Make sure you are in the starting position when pulling the starter rope, as shown in Figure 9. To avoid serious injury, the operator and unit must also be in a stable position while starting.
STARTING/STOPPING INSTRUCTIONS Engine Re-Start: Warm Engine With Fuel NOTE: Four-stroke engines, like cars, are able to start in the idle position. As an alternate method, you may want to start your unit in the idle position when the unit is warm. With the On/Off Stop Control in the START position and the choke lever in the RUN (C) position, pull the starter rope briskly. When the engine starts, run at full throttle for 30 seconds.
OPERATING INSTRUCTIONS ADJUSTING TRIMMING LINE LENGTH The Bump Head™ allows you to release trimming line without stopping the engine. To release more line, lightly tap the cutting head on the ground while operating the trimmer at high speed. See Figure 10. FIGURE 11 TIPS FOR BEST TRIMMING RESULTS 1. The correct angle for the cutting head is parallel to the ground. FIGURE 10 NOTE: Always keep the trimming line fully extended. Line release becomes more difficult as cutting line becomes shorter.
MAINTENANCE & REPAIR INSTRUCTIONS MAINTENANCE SCHEDULE NOTE: Maintenance, replacement, or repair of the emission control devices and system may be performed by any non-road engine repair establishment, individual or authorized service dealer. In order to assure peak performance of your engine, inspection of the engine exhaust port may be necessary after 50 hours of operation. If you notice lost RPM, poor performance or general lack of acceleration, this service may be required.
MAINTENANCE & REPAIR INSTRUCTIONS NOTE: Always use the correct line length when installing trimming line on the unit. The line may not release properly if it is too long. Winding the Inner Reel With New Line 1. Hold the outer spool with one hand and unscrew the Bump Knob clockwise. Inspect the bolt inside the Bump Knob to make sure it moves freely. Replace the Bump Knob if damaged. 2. Remove the inner reel from the outer spool. See Figure 12.
MAINTENANCE & REPAIR INSTRUCTIONS Membrane Line Installation 8. Take approximately 20 feet (6.1 m) of new trimming line. Insert one end of the line through one of the two holes in the inner reel. Pull the line through the inner reel until only about 4 inches is left out. See Figure 17. 9. Insert the end of the line into the open hole in the inner reel and pull the line tight to make the loop as small as possible. See Figure 17.
MAINTENANCE & REPAIR INSTRUCTIONS AIR FILTER MAINTENANCE WARNING: To avoid serious personal injury, always turn off your trimmer and allow it to cool before you clean or maintain it. Clean and re-oil the air filter every 10 hours of operation. It is an important item to maintain. Failure to maintain the air filter will VOID the warranty. 1. Remove the air filter cover by pulling up the two tabs on the bottom back of the cover, then pull out and up. See Figure 20. 2. Remove the air filter. 3.
MAINTENANCE & REPAIR INSTRUCTIONS CHECKING THE OIL LEVEL CHANGING THE OIL For a new engine, change the oil after the first 10 hours of operation. Change the oil while the engine is still warm. The oil will flow freely and carry away more impurities. CAUTION: To prevent extensive engine wear and damage to the unit, always maintain the proper oil level in the crankcase. Never operate the unit with the oil level below the bottom of the dipstick. CAUTION: Wear gloves to prevent injury when handling the unit.
MAINTENANCE & REPAIR INSTRUCTIONS CARBURETOR SETTING Idle Speed Screw The idle speed of the engine is adjustable through the air filter/muffler cover. See Figure 26. NOTE: Careless adjustments can seriously damage your unit. An authorized service dealer should make carburetor adjustments. Check Fuel Mixture Old or dirty fuel is usually the reason for improper unit performance. Drain and refill the tank with fresh fuel prior to making any adjustments. Refer to Oil and Fuel Information. FIGURE 26 3.
MAINTENANCE & REPAIR INSTRUCTIONS 1. Loosen the four (4) screws shown in Figure 27. 7. Pull the starter rope slowly to bring the piston to the top of its travel, (known as top dead center). Check that: • While looking in the spark plug hole, the piston is at the top of its travel. See Figure 29. • Both rocker arms move freely, and both valves are closed. Engine Cover Remove Screws If not, repeat this step. 8. Slide the feeler gauge between the rocker arm and the valve return spring.
MAINTENANCE & REPAIR INSTRUCTIONS REPLACING THE SPARK PLUG STORAGE Use a Champion RDZ19H spark plug (or equivalent). The correct air gap is 0.635 mm (0.025 in.) Remove the plug after every 25 hours of operation and check its condition. 1. Stop the engine and allow it to cool. Grasp the plug wire firmly and pull it from the spark plug. 2. Clean around the spark plug. Remove the spark plug from the cylinder head by turning a 5/8-inch socket counterclockwise. 3. Replace cracked, fouled or dirty spark plug.
