Figure 27 Idle the engine briefly before stopping (about 2 minuts), then slide the ignition switch to the “O” (engine OFF) position. See Figure 27. Figure 28 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. Check and Adjust Idle Speed 1. Start the engine and allow it to warm up at low rpm. 2. If the cutting attachment rotates at engine idle, reduce idle speed by turning the idle adjusting screw counter-clockwise. See Figure 28. NOTE: Standard idle speed is 2,750 (+/– 250) rpm (min-1). WARNING! The cutting attachment must NEVER rotate at engine idle! If the idle speed cannot be adjusted by the procedures described here, return the trimmer to your Shindaiwa dealer for inspection. IMPORTANT! P231_19 Figure 17 16 Sprocket Cover Nut Units with emission control systems are equipped with factory preset carburetor adjustments. Only idle adjustment can be done in the field. 21 OPERATION OPERATION CAUTION! Adjusting Engine Idle Starting the Engine (continued) Chain Oiler Adjusting Oil Flow Rate IMPORTANT! WARNING! The cutting attachment may rotate when the engine is started! 5. When the engine starts, slowly move the choke lever to the "OPEN" position. See Figure 26. (If the engine stops after the initial start, close the choke and restart.) 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. When the Engine Starts... ■ After the engine starts, allow the engine to warm up at idle 2 or 3 minutes before operating the unit. 23122 Figure 26 WARNING! Never start the engine from the operating position. ■ 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 the next page). CAUTION! Never fill the oil reservoir nor adjust the oiler with the engine running. IMPORTANT! The service life of the chain and guide bar is affected by the quality of the lubricant. Using superior lubricant such as Shindaiwa Bar and Chain Oil will help ensure a long service life, For cold weather operation, mix bar and chain oil with an equal part of kerosene. Filling The Oil Reservoir NOTE: The oil reservoir has a capacity sufficient to provide about 40 minutes of cutting time (when set to deliver the minimum flow rate, or about as long as you’ll get from a tank of fuel). 1. Place the pole pruner on a clean, flat surface with the oil filler cap facing up. See Figure 20. Wipe off any debris from the oil cap and from around the oil filler neck. An increase in bar oil flow rate will speed oil consumption, requiring more frequent checks on the oil reservoir. To ensure sufficient lubrication, it may be necessary to check the oil level more frequently than at fuel tank refills. The guide bar and chain are lubricated automatically by a pump that operates whenever the chain rotates. The pump is set at the factory to deliver a minimum flow rate, but it can be adjusted in the field. A temporary increase in oil flow is often desirable when cutting materials such as hardwood or wood with a lot of pitch. Adjust the pump as follows: 1. Stop the engine and make sure the stop switch is in the OFF position. 2. Place the unit on its side with the oil reservoir up. See Figure 21. Oil Reservoir P231_23 Oil Filler Cap Figure 21 Oil Flow Adjusting Screw CAUTION! P231_22 Figure 20 2. Remove the oil filler cap and fill the reservoir with bar and chain oil, then replace the cap. 3. Wipe up spilled oil from the unit before restarting the pole pruner. The oil flow adjusting screw must be pressed in slightly in order to turn. Failure to do so could damage the pump and screw. 3. With a screwdriver, push in on the oil flow rate adjusting screw and turn in the desired direction (there are three incremental settings): • clockwise–decrease lubrication. • counter clockwise–increase lubrication. 20 17 OPERATION OPERATION Open WARNING! Starting the Engine Mixing Fuel CAUTION! Some types of gasoline contain alcohol as an oxygenate. Oxygenated gasoline may cause increased operating temperatures. Under certain conditions, alcoholbased gasoline may also reduce the lubricating qualities of some 2cycle 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 2-cycle type engines, and should never be used in your Shindaiwa engine. 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 in catalyst equipped units can lead to excessive carbon deposits. ■ Use only fresh, clean unleaded gasoline with a pump octane of 87 or higher. ■ 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. Minimize the risk of fire! ■ Stop engine before refueling. ■ Always allow the pole pruner to cool before refueling! ■ Wipe all spilled fuel and move the pole pruner at least 10 feet (3 meters) from the fueling point before restarting! ■ Never start or operate this unit if there is a fuel leak! ■ Never start or operate this unit if the carburetor, fuel lines, fuel tank and/or fuel tank cap are damaged. ■ Never smoke or light any fires near the trimmer or fuel! ■ Never place any flammable material near the engine muffler! ■ Never operate the engine without the muffler and spark arrester in place and properly functioning! IMPORTANT! 23122 Figure 22 Figure 24 1. Slide the ignition switch to the “I” position (engine ON). 3. Set the choke lever to the CLOSED position if engine is cold. Return Tube Make sure the cutting head is clear of obstructions! 1. Place the pole pruner on a flat, level surface. 2. Clear any dirt or other debris from around the fuel filler cap. 3.
