If the fuel filter is dirty, remove it and wash it with nonflammable solvent.
SERVICING YOUR HONDA STICK EDGER EDGER Removal and Installation Always wear gloves when working around the blade. Blade Inspection Always wear gloves when working around the blade. Before each use, check the blade and split pin for wear and damage, and check the tightness of the blade nut. Examine the entire head area, including the grass deflector, and clear or clean dirt, debris, or any other foreign materials from it.

STORAGE STORAGE PREPARATION Proper storage preparation is essential for keeping your stick edger trouble free and looking good. The following steps will help to keep rust and corrosion from impairing your stick edger's function and appearance, and will make the engine easier to start when you use the stick edger again. Cleaning Before washing the stick edger head area, disconnect the spark plug cap. Wash the stick edger, including the area around the stick edger head.
STORAGE Adding Fuel Stabilizer to Extend Fuel Storage Life When adding a fuel stabilizer, fill the fuel tank with fresh gasoline. If only partially filled, air in the tank will promote fuel deterioration during storage. If you keep a container of gasoline for refueling, be sure that it contains only fresh gasoline. Add fuel stabilizer following the manufacturer's instructions.
TRANSPORTING BEFORE LOADING If the engine has been running, allow it to cool for at least 15 minutes before loading the stick edger on the transport vehicle. A hot engine and exhaust system can burn you and can ignite some materials. Always turn the ignition switch to the OFF (0) position. Make sure the fuel cap is securely tightened. LOADING The stick edger may be secured by suitable clamps, hangers or straps.
TAKING CARE OF UNEXPECTED PROBLEMS ENGINE STARTING PROBLEMS Engine Will Not Start Check control positions. Check fuel. Possible Cause Correction Ignition switch OFF (0). Turn ignition switch ON (l). Choke not in CLOSED (cold engine). Move choke to the CLOSED position. Out of fuel. Add fuel. Bad fuel, stick edger stored without Drain fuel tank and carburetor, treating or draining gasoline, refuel with fresh gasoline. refueled with bad gasoline. Remove spark plug.
TAKING CARE OF UNEXPECTED PROBLEMS BLADE PROBLEMS Blade Won’t Stop Turning When Throttle in SLOW Position Possible Cause Correction Check throttle control and cable. Fault in throttle control or cable; throttle cable out of adjustment or bent. Check throttle control parts, adjust or replace cable if necessary. Check clutch. Clutch springs broken or worn, or clutch system faulty. Replace clutch springs or replace/repair other clutch system parts.
TECHNICAL & CONSUMER INFORMATION TECHNICAL INFORMATION This section contains important information about serial number locations, operation at high altitudes, oxygenated fuels and emissions control systems. Serial Number Locations Carburetor Modifications for High Altitude Operation At high altitude, the standard carburetor air-fuel mixture will be too rich. Performance will decrease, and fuel consumption will increase. A very rich mixture will also foul the spark plug and cause hard starting.
TECHNICAL & CONSUMER INFORMATION Oxygenated Fuels Some conventional gasolines are being blended with alcohol or an ether compound. These gasolines are collectively referred to as oxygenated fuels. To meet clean air standards, some areas of the USA and Canada use oxygenated fuels to help reduce emissions. If you use an oxygenated fuel, be sure it is unleaded and meets the minimum octane rating requirement. Before using an oxygenated fuel, try to confirm the fuel's contents.
TECHNICAL & CONSUMER INFORMATION Problems That May Affect Emissions If you are aware of any of the following symptoms, have your engine inspected and repaired by your servicing dealer.
TECHNICAL & CONSUMER INFORMATION CONSUMER INFORMATION Honda Publications Two other documents are available from your Honda dealer. There is a shop manual, which covers complete maintenance and overhaul procedures. It is intended to be used by a skilled technician.
