  • Page 12: Pre-Operation Checks

    4. PRE-OPERATION CHECKS 4. PRE-OPERATION CHECKS CHECK YOUR LAWN For your safety and for the safety of others, always inspect the area before mowing. Objects Anything which can be picked up by the blade(s) and thrown is a potential hazard to you and others. Look for things like stones, sticks, bones, and wire. Remove them from the mowing area.
  • Page 13 When a blade needs sharpening or replacement take the lawn mower to an authorized Honda dealer. Or, if you have a torque wrench, you can remove and install the blade(s) yourself (pages 52–53).
  • Page 14 4. PRE-OPERATION CHECKS Engine Oil Level Check the engine oil level with the engine stopped and the mower on a level surface. Use 4-stroke motor oil that meets or exceeds the requirements for API service classification SH or equivalent. Always check the API SERVICE label on the oil container to be sure it includes the letters SH or equivalent.
  • Page 15 4. PRE-OPERATION CHECKS Fuel Fuel tank capacity: 1.1  Refuel in a well-ventilated area before starting the engine. If the engine has been running, allow it to cool. Never refuel the mower inside a building where gasoline fumes may reach flames or sparks.
  • Page 16 4. PRE-OPERATION CHECKS Fuel Recommendations Use gasoline with an octane rating of 86 or higher (unleaded preferred). This engine is designed 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.
  • Page 17 4. PRE-OPERATION CHECKS 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 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.
  • Page 18 4. PRE-OPERATION CHECKS Air Cleaner Inspection Remove cover [1]. Make sure the filter [2] is clean and in good condition. A dirty air filter will restrict air flow to the carburetor, reducing engine performance. Refer to page 43 for air cleaner service. Handlebar Height Adjustment Handlebar [1] height can be adjusted to three positions: high [2], middle [3], and low [4].
  • Page 19 4. PRE-OPERATION CHECKS Grass Bag (HRB536C) 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% filled.
  • Page 20 4. PRE-OPERATION CHECKS Mulching Plug (HRM536C) The mulching plug [1] contours the mower deck for efficient mulching. You can quickly remove the plug to install a grass bag or side-discharge chute, which are available as optional equipment. Raise the discharge guard [2] to remove or install the mulching plug.

  • Page 21: Operation

    5. OPERATION 5. OPERATION MOWING PRECAUTIONS Before operating the mower for the first time, please review chapters 1 and 2. Even if you have operated other mowers, take the time to become familiar with how this mower works and practice in a safe area until you build up your skills.
  • Page 22 5. OPERATION 3. Pull the starter grip [1] lightly until you feel resistance, then pull briskly. Return the starter grip gently. To keep the blade(s) from turning and to prevent the mower from moving forward, always release the blade control lever [2] and drive clutch lever [3] when you operate the starter.
  • Page 23 Operation at altitudes below 1,800 meters with a modified carburetor may cause the engine to overheat and result in serious engine damage. For use at low altitudes, have your authorized Honda dealer return the carburetor to original factory specifications.
  • Page 24 5. OPERATION OPERATING THE CONTROLS FOR MOWING Throttle Lever For best cut quality, always mow with the throttle lever [1] in the fast position [2]. When the blade rotates at the preset fast speed, it creates a strong fan action that lifts and cuts grass more efficiently.
  • Page 25 5. OPERATION Drive Clutch Lever Push the drive clutch lever [1] forward to propel the mower forward. For self-propelled mowing, press the yellow button [2] on top of the blade control lever [3], push the blade control lever forward to the handlebar, then push the drive clutch lever [1] forward.
  • Page 26 5. OPERATION Shift Lever Use the shift lever [1] to select the forward speed at which you wish to mow. Do not use the throttle lever to adjust your forward speed. The throttle lever must remain in the fast position for good mowing performance. Otherwise, cut quality suffers.
  • Page 27 5. OPERATION STOPPING THE ENGINE 1. Release the drive clutch lever [1] and blade control lever [2]. 2. Move the throttle lever [1] to the STOP position [2] to stop the engine. STOP 3. When the mower is not in use, turn the fuel valve [1] to the OFF position.
  • Page 28 5. OPERATION SAFE MOWING PRACTICES For your safety, keep all four wheels on the ground, and be careful to avoid losing your footing and your 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 29 5. OPERATION Obstacles Use the side of the mower to cut close to large 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.
  • Page 30 5. OPERATION MOWING TIPS When to Mow Most grasses should be mowed when they have grown 1/2 to 1 inch above their recommended height. More frequent mowing is required for mulching than for bagging. For best results, you may need to mow the lawn twice a week during the growing season.
  • Page 31 5. OPERATION Blade Speed The blade must spin very fast to cut properly. Always use the fast throttle setting, and keep the engine running at maximum rpm. If engine speed drops, it could mean the engine is being overloaded by the blade trying to cut too much grass.
  • Page 32 5. OPERATION Mowing Patterns Your Honda mower will work most efficiently if you use the following mowing patterns as much as possible. Mower deck and equipment design, and the direction in which the blade rotates, cause these mowing patterns to give the best results.

  • Page 33: Transporting/Storage

    6. TRANSPORTING/STORAGE 6. TRANSPORTING/STORAGE 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 [1] to the OFF position.
  • Page 34 6. TRANSPORTING/STORAGE Loading and Unloading Position the mower so all four wheels are on the bed of the transport vehicle. Tie the mower down with rope or straps, and block the wheels. Keep the tie- down rope or straps away from the controls, adjustment levers, cables, and the carburetor.
  • Page 35 Wear heavy gloves to protect your hands from the blade(s). Grass Bag (HRB536C) Remove the bag from the mower, and wash it with a garden hose or pressure washing equipment. Allow the bag to dry completely before storage.
  • Page 36 6. TRANSPORTING/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 37 6. TRANSPORTING/STORAGE Draining the Fuel Tank and Carburetor:  WARNING Gasoline is highly flammable and explosive. You can be burned or seriously injured when handling fuel. • Stop the engine and keep heat, sparks, and flame away. • Handle fuel only outdoors. •...
  • Page 38 6. TRANSPORTING/STORAGE PLACING IN STORAGE 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.

  • Page 39: Maintenance

    Other service tasks that are more difficult, or require special tools, are best handled by professionals and are normally performed by a Honda technician or other qualified mechanic. The maintenance schedule applies to normal operating conditions. If you operate your mower under unusual conditions, consult an authorized Honda dealer for recommendations applicable to your individual needs and use.
  • Page 40 Keep cigarettes, sparks, and flames away from all fuel-related parts. Remember that your Honda dealer knows your mower best and is fully equipped to maintain and repair it. To ensure the best quality and reliability, use only new, genuine Honda parts or their equivalents for repair and replacement.
  • Page 41 Every 2 years (2) (1) Service more frequently when used in dusty areas. (2) These items should be serviced by an authorized Honda dealer, unless you have the proper tools and are mechanically proficient. Refer to the Honda shop manual for service procedures.
  • Page 42 7. MAINTENANCE ENGINE MAINTENANCE Engine Oil Change Drain the oil while the engine is warm. Warm oil drains quickly and completely. 1. Put the throttle lever in the STOP position and turn the fuel valve OFF. This will reduce the possibility of fuel leakage (page 8). 2.
  • Page 43 7. MAINTENANCE 5. After changing the engine oil, and before starting the engine, check the oil level with the mower on a level surface: a. Remove the filler cap/dipstick [1]. b. Wipe the dipstick [1] clean. c. Insert and remove the dipstick [1] without screwing it into the filler neck. Check the oil level shown on the dipstick.
  • Page 44 7. MAINTENANCE Air Cleaner Service A dirty air filter will restrict 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 45 7. MAINTENANCE Spark Plug Service Recommended spark plugs: NGK - BPR6ES DENSO - W20EPR-U The spark plugs listed above have an internal resistor. Resistor spark plugs reduce interference with radio and TV reception. NOTICE Incorrect spark plugs can cause engine damage. For good performance, the spark plug [1] must be properly gapped and free of deposits.
  • Page 46 7. MAINTENANCE 3. Inspect the spark plug. Replace it if 0.7 ~ 0.8 mm the electrodes are worn, or if the insulator is cracked or chipped. Clean the spark plug with a wire brush if you are going to reuse it. 4.
  • Page 47 7. MAINTENANCE Carburetor Adjustments 1. Start the engine outdoors, and allow it to warm up to normal operating temperature. 2. Set the throttle lever in the slow position. 3. Turn the pilot screw [1] in or out to the setting that produces the highest idle rpm.
  • Page 48 If the blade does not start or stop as it should, with correct cable adjustment, take the mower to an authorized Honda dealer for repair. Drive Clutch Cable (TXE, TXF) 1 ~ 5 mm Measure free play at the top of the drive clutch lever [1].
  • Page 49 Check that the transmission shifts properly, and that the lever is approximately aligned with the numbers beside it. If the transmission does not shift as it should with correct cable adjustment, take the mower to an authorized Honda dealer for repair.
  • Page 50 7. MAINTENANCE Drive Clutch Cable Adjustment (HXE) 1. With the engine stopped, position the control cable bands [1] as shown. 2. Pull the shift lever [2] all the way back to the neutral position. 3. Start the engine and move the throttle lever [3] to the FAST position.
  • Page 51 7. MAINTENANCE 5. Loosen the top [1] and bottom [2] drive clutch cable locknuts with a 10 mm wrench. Move the adjuster [3] up or down, as required, until the mower operates as outlined in step 4. Tighten the locknuts.
  • Page 52 7. MAINTENANCE THROTTLE CABLE ADJUSTMENT 1. Move the throttle lever [1] to the fast position [2]. 2. Remove air cleaner cover. 3. Measure clearance between control choke arm [3] and control lever [4]. Clearance should be 0 ~ 1 mm. If clearance is correct, no adjustment is necessary.
  • Page 53 BLADE SHARPENING: To avoid weakening the blade(s), or causing imbalance or poor cutting, the blade(s) should be sharpened by trained staff at an authorized Honda dealer. BLADE REPLACEMENT: Use genuine Honda replacement blades or their equivalent. Blade Removal 1. Put the throttle lever in the STOP position and turn the fuel valve OFF.
  • Page 54 [1] from turning. Blade bolt torque: 49 ~ 59 N·m If you do not have a torque wrench, have an authorized Honda dealer tighten the blade bolts before you use the mower. If the blade bolts are overtightened, they could break.
  • Page 55 Wash the bag with a garden hose, and allow it to dry completely before use; a wet bag will clog quickly. Grass Bag Replacement Replace a worn or damaged bag with a Honda replacement bag or its equivalent. Bag Removal 1.
