  • 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 blades yourself (pages 53–54).
  • 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 Occasionally you may hear light “spark knock” or “pinging” (metallic rapping noise) while operating under heavy loads. This is no cause for concern. If spark knock or pinging occurs at a steady engine speed, under normal load, change brands of gasoline.
  • Page 17 4. PRE-OPERATION CHECKS Fuel system damage or performance problems resulting from the use of an oxygenated fuel containing more than the percentages of oxygenates mentioned above are not covered under warranty. 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.
  • Page 18 4. PRE-OPERATION CHECKS 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% filled.
  • Page 19 4. PRE-OPERATION CHECKS Cutting Height Check the mower deck cutting height settings, and be sure that all four adjustment levers [1] are set to the same cutting height position. To adjust cutting height, pull each adjustment lever [1] toward the wheel, and move it into another notch.
  • Page 20 4. PRE-OPERATION CHECKS Clip Direction Clip Director Knob Adjustment Adjust the clip director knob [1] in any one of the ten positions to achieve the desired mowing results. To adjust the clip director knob, pull the knob downward and towards the rear of the mower.
  • Page 21 4. PRE-OPERATION CHECKS Sliding Door Position The sliding door [2] can be positioned to produce different mowing results. If the preferred sliding door position is unknown, install a grass bag and begin mowing with the clip director knob [1] all the way to the BAG position. Check the appearance of the lawn.
  • Page 22 4. PRE-OPERATION CHECKS Rear Discharge To discharge clippings to the rear, remove the grass bag and position the clip director knob [1] in the BAG range. Maximum rear discharge will occur when the clip director knob is all the way to the left (BAG) position. As the clip director knob is moved toward the right (MULCH) position, less grass will be discharged though the rear discharge guard.

  • Page 30 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 31 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 32 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 33 5. OPERATION Blade Sharpness A sharp blade cuts cleanly. A dull blade tears the grass, leaving shredded ends that turn brown. When your blade doesn't cut cleanly anymore, have it sharpened or replaced. Dry Grass If the ground is too dry, mowing will stir up a lot of dust. Besides being unpleasant to work in, too much dust will clog the carburetor air filter.
  • Page 34 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 35: 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.
