• • • • • FOR YOUR SAFETY (page 2) PARTS AND CONTROLS (page 3) BEFORE EACH OPERATION (page 7) OPERATION (page 9) MAINTENANCE SCHEDULE (page 15) BEFORE EACH OPERATION Your safety is your responsibility. A little time spent in preparation will significantly reduce your risk of injury. Read and understand this manual. Know what the controls do and how to operate them. Familiarize yourself with the trimmer and its operation before you begin using it.
PAGE 8
Check Your Shoulder Harness and Trimmer Adjustment Adjusting the Harness Adjust the harness so the quick-release latch is at your right hip, as shown. Check the Engine Oil Level Check the engine oil level before each use, or every 10 hours if operated continuously. Rest the trimmer on a level surface with the engine stopped. 1. Rest the trimmer on a level surface as shown. 2. Remove the oil filler cap/dipstick and wipe it clean.
PAGE 9
Add Fuel This engine is certified to operate on regular gasoline with a pump octane rating of 86 or higher. Never use stale or contaminated gasoline or an oil/gasoline mixture. Avoid getting dirt or water in the fuel tank. You may use regular unleaded gasoline containing no more than 10% ethanol (E10) or 5% methanol by volume. In addition, methanol must contain cosolvents and corrosion inhibitors.
PAGE 10
Turn the Engine Off When Not Trimming Thrown Debris If you stop trimming or cutting for any reason, even to clean off the cutting attachment, always shut off the engine. The trimmer will throw debris in the direction of blade movement at the point of contact. Keep People Away From Your Working Area To prevent injury to others, keep people at least 50 feet (15 meters) away from the working area during operation.
PAGE 11
OPERATING TIPS Operation on Slopes Start on the low side of a slope, and work upward. This will reduce your risk of slipping and falling, and it will give you a cutting angle that will better enable you to direct debris away from you. Scything Motion Swing the trimmer in a level arc by rotating your body with a smooth, easy motion, rather then moving the trimmer with your arms. Do not chop at tough weeds and brush; let the cutting line or blade work through tough growths gradually.
PAGE 12
Operating the Controls Throttle Trigger The location and operation of the controls are similar on both the HHT25S and HHT35S models. The throttle trigger controls engine speed. Choke Lever The choke lever opens and closes the choke valve. The CLOSED position enriches the fuel mixture for starting a cold engine. The OPEN position provides the correct fuel mixture for operation after starting, and for restarting a warm engine.
PAGE 13
Starting the Engine 1. To start a cold engine, move the choke lever to the CLOSED position. To restart a warm engine, leave the choke lever in the OPEN position. CHOKE LEVER 7. If the choke lever was moved to the CLOSED position to start the engine, gradually move it to the OPEN position as the engine warms up. Allow the engine to warm up for a few minutes after a cold start. When the engine is warm enough to idle well, pull and release the throttle trigger to disengage the throttle set button. 8.
PAGE 14
Harness Quick Disconnect Using a Nylon Cutting-Line Head To quickly detach the trimmer from the harness, pull the quick-release latch tab upward. As the ends of the line wear away, more line must be released from the cutting-line head. Your trimmer is factory-equipped with either a Kwik Loader or a semi-matic (bump feed) cutting-line head, which have different procedures for releasing line.
PAGE 15
SERVICING YOUR TRIMMER gasoline, to clean parts. Keep cigarettes, sparks, and flames away from all fuel-related parts. Maintenance Schedule Proper maintenance is essential for safe, economical, and trouble-free operation. It also helps reduce air pollution. Interval 1  WARNING Improper maintenance, or failure to correct a problem before operation, can cause a significant malfunction. Before each use Some malfunctions can seriously hurt or kill you.
PAGE 16
Oil Change Air Filter Change the oil after the first 10 hours of use. Thereafter, change the oil every 6 months or 50 hours of use. Change the oil more often when used in dusty areas. Drain the used oil while the engine is warm. Warm oil drains quickly and completely. 1. Place a suitable container below the engine to catch the used oil. 2. Remove the oil filler cap/dipstick. 3. Tip the trimmer to drain the used oil through the oil filler opening. Allow the used oil to drain completely.
PAGE 17
Spark Plug Cleaning A dirty air filter will restrict air flow to the carburetor, reducing engine performance. If you operate the trimmer in very dusty areas, clean the air filter more often than specified in the MAINTENANCE SCHEDULE (page 15). Honda Air Filter Oil can be used instead of clean engine oil and is available from your authorized Honda dealer (page 29). Check the spark plug every year or 100 hours of use. Replace the spark plug every 2 years or after 300 hours of use.
PAGE 18
Spark Arrester Cooling Fin Inspection The spark arrester must be serviced every 100 hours to keep it functioning as designed. Your trimmer engine is factory-equipped with a spark arrester. In some areas, it is illegal to operate an engine without a spark arrester. Check local laws and regulations. If the engine has been running, the muffler will be very hot. Allow the muffler to cool before servicing the spark arrester. 1. Remove the 5 x 12 mm hex bolt and top cover.
PAGE 19
Fuel Tube Inspection Check the fuel supply and return tubes, and replace any tube that is damaged, cracked, or leaking. Refer to the Honda shop manual for tube replacement instructions, or take the trimmer to an authorized Honda servicing dealer. CUTTING ATTACHMENTS Applications Fuel Filter and Fuel Tank Cleaning ATTACHMENTS FOR TRIMMING GRASS AND LIGHT WEEDS 1. Remove the fuel tank cap. 2. Tip the trimmer and empty the fuel tank into an approved gasoline container.
PAGE 20
Blades A dull blade can be sharpened, but a blade that is worn out, bent, cracked, chipped, or otherwise damaged must be replaced. If installing a metal blade on a Honda trimmer equipped with a loop handle, also install the optional Barrier Kit that includes a full shoulder harness, a barrier bar, and two different debris shields for metal blades. Follow the safety information and installation instructions that come with the kit.
PAGE 21
Debris Shields Changing the Debris Shield Always use the correct debris shield when operating the trimmer. In addition to safety concerns, it can cause an overload to the clutch due to excessive line length. Clutch failure due to running the trimmer without a shield installed is not covered under warranty. Refer to the applicable illustration for removing and installing the debris shields. Tighten the spacer bolts/washers to the specified torque.
PAGE 22
Cutting-Line Heads Kwik Loader Cutting-Line Head All Honda trimmers come with either a Kwik Loader or semi-matic cutting head. Read this section to learn how to inspect, install new line, and remove and install a cutting head from the trimmer. A cutting-line head containing nylon monofilament line and a debris shield with a cutoff knife is standard equipment. The shield’s cutoff knife automatically removes any excess line that is released from the cutting head.

4. Hold the housing securely, then continue to rotate the spool in the direction of the arrow an additional 1/4 inch or the width of the channel to unlock the spool from the housing. spool reaches the bottom of the housing, the lines should snap out of the spool notches. If you are not sure if the lines have snapped out of the notches, gently pull the spool away from the housing about an 1/8 inch to inspect the lines. If necessary, gently pull each line until your hear it snap out of the notch.
PAGE 24
TRANSPORTING Before Loading If the engine has been running, allow it to cool for at least 15 minutes before loading the trimmer on the transport vehicle. A hot engine and exhaust system can burn you and can ignite some materials. 1. Turn the engine switch to the OFF position. Draining the Fuel Tank and Carburetor  WARNING Gasoline is highly flammable and explosive, and you can be burned or seriously injured when refueling. • • • • Stop the engine and let cool before refueling.
PAGE 25
Storage Location Cutting-Line Head Won’t Stop Turning If your trimmer will be stored with gasoline in the fuel tank and carburetor, it is important to reduce the hazard of gasoline vapor ignition. Select a well-ventilated dry storage area away from any appliance that operates with a flame, such as a furnace, water heater, or clothes dryer. Also avoid any area with a spark-producing electric motor, or where power tools are operated.
PAGE 26
High Altitude Operation Problems That May Affect Emissions At high Altitudes, 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. Operation at an Altitude that differs from that at which this engine was certified, for extended periods of time, may increase emissions.

AVOIDING FUEL-RELATED PROBLEMS When maintained properly, your Honda trimmer should provide years of trouble-free operation. This includes the fuel system. However, gasoline can quickly deteriorate, causing starting or running problems and, in some cases, damage to the fuel system. Most fuel-related problems can be avoided by following the precautions listed below.
