BEFORE OPERATION Mulching Plug The mulching plug helps to curve the inside of the mower deck for more efficient mulching. Install and remove the mulching plug by raising the rear discharge guard as shown. The mulching plug only fits one way. Remove the mulching plug when using a grass bag.
Page 15
Grass Bag A lawn mower works like a vacuum cleaner; it blows air through the bag, which traps the grass clippings. Always empty the grass bag before it becomes filled to the limit of its capacity. Bagging performance will diminish after the bag becomes about 90% full. Also, the bag is easier to empty when not packed full.
OPERATION MOWING PRECAUTIONS Before operating the mower for the first time, please review the LAWN MOWER SAFETY chapter beginning on page 4 and the BEFORE OPERATION chapter beginning on page 10. Even if you have operated other mowers, take time to become familiar with how this mower works and practice in a safe area until you build up your skills.

SAFE MOWING PRACTICES For your safety, keep all four wheels on the ground, and be careful to avoid losing your footing and control of the mower. Keep a firm grip on the handlebar and walk, never run, with the mower. Be very careful when mowing uneven or rough ground.
Page 22
OPERATION Obstacles Use the side of the mower to cut close to obstacles, such as fences or walls. Release the drive clutch lever to disengage the drive when mowing around trees and other obstacles. Push the mower around obstacles for better directional control. Be careful when mowing over obstacles embedded in the lawn, such as sprinkler heads, paving, edging, etc.
MOWING TIPS Which Blades? Grasses and lawn conditions vary greatly, so Harmony II models can use various combinations of standard and accessory blades. Use this blade application guide to help determine which blades are best suited for your lawn. For more information about blades, see page 55. Always use an upper and lower blade.
Page 24
OPERATION Blade Speed The blades must spin very fast to cut properly. If the engine speed drops, it could mean the engine is being overloaded by the blades trying to cut too much grass. Mow a narrower swath, move the mower slower, install the discharge chute, or raise the cutting height.
Page 25
OPERATION Clogged Mower Deck Before clearing a clogged mower deck, stop the engine and turn the fuel valve to the OFF position. With the spark plug cap disconnected, tilt the mower so the carburetor side is up. Clear a clogged deck with a stick, not your hands. Mowing Patterns Your Honda mower will work most efficiently if you use the following mowing patterns as much as possible.
SERVICING YOUR MOWER THE IMPORTANCE OF PROPER MAINTENANCE Proper maintenance is essential for safe, economical, and trouble-free operation. It will also help reduce air pollution. Improper maintenance, or failure to correct a problem before operation, can cause a malfunction in which you can be seriously hurt or killed.
MAINTENANCE SAFETY Some of the most important safety precautions follow. However, we cannot warn you of every conceivable hazard that can arise in performing maintenance. Only you can decide whether or not you should perform a given task. Failure to properly follow maintenance instructions and precautions can cause you to be seriously hurt or killed.
(1) Service more frequently when used in dusty areas. (2) These items should only be serviced by an authorized Honda servicing lawn mower dealer, unless you are mechanically proficient and have the proper tools. Refer to the Honda shop manual for service procedures.
A worn or damaged blade can break, causing blade pieces to be thrown from the mower. When a blade needs sharpening or replacement, take the lawn mower to an authorized Honda servicing dealer. Or, if you have a torque wrench, you can remove and install the blades yourself (page 28).
SERVICING YOUR MOWER Blade Removal and Installation If you remove the blades, use a torque wrench for installation. Wear heavy gloves to protect your hands. To avoid weakening the blades or causing imbalance or poor cutting, the blades should be sharpened by trained staff at an authorized Honda servicing dealer.
3. Tighten the bolts with a torque wrench. Use a wooden block to stop the blades from turning. Blade bolt torque: 36 ~ 43 ft-lb (49 ~ 59 N·m) If you don’t have a torque wrench, have an authorized Honda servicing dealer tighten the blade bolts before you use the mower.
SERVICING YOUR MOWER ENGINE MAINTENANCE Engine Oil Level Check 1. Wipe the dipstick clean. 2. Insert and remove the dipstick without screwing it into the filler neck. Check the oil level shown on the dipstick. 3. If the oil level is low, add oil to bring the level between the upper and lower limit marks on the dipstick as shown.
Page 33
Engine Oil Change Drain the used oil while the engine is warm. Warm oil drains quickly and completely. 1. Turn the fuel valve to OFF to reduce the possibility of fuel leakage (page 18). 2. Wipe the oil filler area clean, then remove the oil filler cap/dipstick. 3.
Page 34
SERVICING YOUR MOWER Air Cleaner Service A dirty air filter restricts air flow to the carburetor, reducing engine performance. If you operate the mower in very dusty areas, clean the air filter more often than specified in the MAINTENANCE SCHEDULE. NOTICE Operating the engine without an air filter, or with a damaged filter, will allow dirt to enter the engine, causing rapid engine wear.
Page 35
Spark Plug Service Recommended spark plugs: BPR6ES (NGK) or W20EPR-U (DENSO) For good performance, the spark plug must be properly gapped and free of deposits. NOTICE An incorrect spark plug can cause engine damage. 1. Disconnect the spark plug cap and remove dirt from the area.
SERVICING YOUR MOWER SPARK ARRESTER SERVICE (optional equipment) Your lawn mower engine is not 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. An optional USDA approved spark arrester is available from an authorized Honda servicing dealer.
FUEL SYSTEM Refueling Fuel tank capacity: 0.29 US gal (1.1 l) If the fuel level is low, refuel in a well-ventilated area with the engine stopped. If the engine has been running, allow it to cool first. To refuel, remove the fuel tank cap, and fill the tank with gasoline to the bottom of the filler neck.
Page 38
SERVICING YOUR MOWER Fuel Recommendations Use unleaded gasoline with a pump octane rating of 86 or higher. These engines are certified to operate on unleaded gasoline. Unleaded gasoline produces fewer engine and spark plug deposits and extends exhaust system life. Never use stale or contaminated gasoline or an oil/gasoline mixture.
4. Stop the engine and allow it to cool. 5. After the lawn mower is clean and dry, touch up any damaged paint, and coat other areas that may rust with a light film of oil.
Page 40
STORAGE Fuel Gasoline will oxidize and deteriorate in storage. Old gasoline will cause hard starting, and it leaves gum deposits that clog the fuel system. If the gasoline in your mower deteriorates during storage, you may need to have the carburetor and other fuel system components serviced or replaced.
Page 41
Draining the Fuel Tank and Carburetor 1. Remove the carburetor drain bolt with a 10 mm wrench, and drain the carburetor bowl fuel into an approved container. Gasoline is highly flammable and explosive. You can be burned or seriously injured when handling fuel.
STORAGE STORAGE PRECAUTIONS If your mower 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 storage area away from any appliance that operates with a flame, such as a furnace, water heater, or clothes dryer.
TRANSPORTING BEFORE LOADING If the engine has been running, allow it to cool for at least 15 minutes before loading the mower on the transport vehicle. A hot engine and exhaust system can burn you and can ignite some materials. Turn the fuel valve to OFF (page 18).
TAKING CARE OF UNEXPECTED PROBLEMS ENGINE WILL NOT START Possible Cause Fuel valve OFF. Out of fuel. Bad fuel; mower stored without treating or draining gasoline, or refueled with bad gasoline. Spark plug faulty, fouled, or improperly gapped. Spark plug wet with fuel (flooded engine). Fuel filter clogged, carburetor malfunction, ignition malfunction, valves stuck, etc.
TAKING CARE OF UNEXPECTED PROBLEMS VIBRATION PROBLEMS Possible Cause Grass and debris lodged under mower deck. Clean out mower deck (p. 23). Mechanical damage, such as a bent crankshaft. MOWING AND BAGGING PROBLEMS Possible Cause Mower is moving too fast for lawn conditions. Shift to a lower gear or release the drive Adjustment levers set at different positions.
SET-UP Unpacking Remove all the cardboard from the mower, including the piece around the handlebar. Handlebar Setup Loosen the two knobs on the lower handlebar. Hold the flywheel brake lever against the handlebar, and unfold the handlebar into the mowing position. Remove the piece of paper between the handlebar and the frame.

TECHNICAL & CONSUMER INFORMATION TECHNICAL INFORMATION Serial Number Locations ENGINE SERIAL NUMBER There are two serial numbers, one for the mower frame and one for the engine. Record the frame and engine serial numbers in the space below. You will need these serial numbers when ordering parts and when making technical or warranty inquiries (page 60).
Page 49
TECHNICAL AND CONSUMER INFORMATION Carburetor Modification 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. Operation at an altitude that differs from that at which this engine was certified, for extended periods of time, may increase emissions.
Page 50
TECHNICAL AND 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 United States and Canada use oxygenated fuels to help reduce emissions.
TECHNICAL AND CONSUMER INFORMATION EMISSION CONTROL SYSTEM Source of Emissions The combustion process produces carbon monoxide, oxides of nitrogen, and hydrocarbons. Control of hydrocarbons and oxides of nitrogen is very important because, under certain conditions, they react to form photochemical smog when subjected to sunlight. Carbon monoxide does not react in the same way, but it is toxic.
