    I. FOR SAFE OPERATION I. FOR SAFE OPERATION DANGER: Failure to observe the following safety instructions can result in serious injury or death. As the owner or operator of the lawn mower, you are responsible for preventing accidents or injuries. 1.
  • Page 7 1.9. Inspect the lawn mower periodically. If not, this may not only shorten the lawn mower’s service life but also make safe and efficient operation impossible. 1.10. Never use the lawn mower out of normal usage even if it is not mentioned at this operation manual.
  • Page 8: Before Starting The Lawn Mower

    I. FOR SAFE OPERATION 2. BEFORE STARTING THE LAWN MOWER 2.1. Set up an operation plan with sufficient time al- lowance. A tight plan may result in unexpected accidents. Especially when operating the lawn mower under extremely hot, cold, or humid cir- cumstances, set up an operation schedule or method which will ensure operational safety.
  • Page 9 2.13. Be sure to operate the lawn mower equipped with a standard mower deck and collector. Never mow grass without the collector, or the lawn mower scatters grass, stone and other flying debris, which is very dangerous. If you would like not to collect the cut glass in a collector, equip an op- tional discharge cover for collector.
  • Page 10: Operation Of The Lawn Mower

    I. FOR SAFE OPERATION 3. OPERATION OF THE LAWN MOWER 3.1. When the lawn mower is running, stay away from the discharge opening, the cutting unit(s), and all moving parts. 3.2. During operation, never allow anyone, espe- cially children, and animals to be in the vicinity of the lawn mower.
  • Page 11 3.15. Never attempt to do the mowing operation without the discharge cover in place or with the cover left open. 3.16. Never attempt to operate without the drive shaft cover in place. 3.17. Do not attempt to adjust the cutting height while the engine is running.
  • Page 12 I. FOR SAFE OPERATION 3.27. Stay alert and stop the lawn mower if people or animals enter the area. 3.28. Do not carry passengers. 3.29. Never carry children, even when the mower blades are not rotating. Children may fall off the lawn mower and become seriously injured or pre- vent you from operating the lawn mower safely.
  • Page 13: Operation On A Slope

    4. OPERATION ON A SLOPE DANGER: Slopes are a major factor related to accidents with lawn mowers, resulting in severe injuries. We cannot recommend the lawn mower with mower deck be operated on a slope. All slopes require extra caution; no slope is safe. You can lose control of the lawn mower on a slope be- cause of one of the following: - the wheels lack traction;...
  • Page 14: Driving On Public Roads

    I. FOR SAFE OPERATION 4.5. Never perform mowing operation on wet grass. 4.6. Avoid sudden starting and stopping. 4.7. Mow up and down a slope; do not mow across it. 4.8. Mow a slope by moving slowly. Do not suddenly change your speed or direction.
  • Page 15: Loading Onto Or Unloading From A Truck

    6. LOADING ONTO OR UNLOADING FROM A TRUCK 6.1. When loading the lawn mower onto a truck, turn off the truck’s engine, apply the parking brake to the truck, and chock the wheels to avoid unex- pected moving of the truck. 6.2.
  • Page 16: When Filling With Fuel

    I. FOR SAFE OPERATION 7. WHEN FILLING WITH FUEL DANGER: Fuel is highly flammable and ex- plosive. Take the following precautions. 7.1. Do not add or drain fuel indoors, while smoking, or near a source of flame. 7.2. Do not remove the fuel tank cap or add fuel to the tank while the engine is running or hot.
  • Page 17: Mounting And Dismounting Of The Mower Drive Shaft

    8. MOUNTING AND DISMOUNTING OF THE MOWER DRIVE SHAFT The mower gear box is driven through a drive shaft with universal joints from the lawn mower. When connecting or disconnecting the shaft, follow the next instructions. 8.1. Lower the mower deck onto the ground, stop the engine, remove key from the starter switch, and apply the parking brake or parking lock before mounting or dismounting the drive shaft.
  • Page 18 I. FOR SAFE OPERATION 9.7. The engine, muffler, radiator, etc. are very hot just after operation, so wait until those heated parts cool down sufficiently to avoid burns. 9.8. Never remove the radiator cap while the engine is hot or running. Wait until the engine cools down and then relieve the radiator pressure by releas- ing the radiator cap.
  • Page 19 9.27. Never attempt unauthorized modification of the lawn mower as this could be very hazardous. Damaged or worn parts should be replaced with ISEKI genuine spare parts. Unauthorized parts may cause breakdown of the lawn mower, acci- dents, and ISEKI warranty to expire.
  • Page 20: Maintenance Of The Electrical System

    I. FOR SAFE OPERATION 10. MAINTENANCE OF THE ELECTRICAL SYSTEM 10.1. TO MAINTAIN ELECTRIC WIRING (1) When servicing the electric wiring, stop the engine without fail. Otherwise your hands or clothes may be caught in or sandwiched between rotating parts. (2) Before manipulating electric parts, be sure to disconnect the earth battery cable (-), or you may get an electric shock or be injured by sparks.
  • Page 21: Tires And Wheels

    11. TIRES AND WHEELS 11.1. Be sure to keep tire pressures at the levels speci- fied in this manual. Excessively high tire pressure may result in explosion, which may lead to physi- cal accidents. 11.2. If a cut is found in a tire and the cut reaches the cords, do not use it.
  • Page 22: Long Term Storage

    I. FOR SAFE OPERATION 13. LONG TERM STORAGE 13.1. Never store the mower with fuel in the tank inside a building where fumes can reach an open flame or spark 13.2. Lower the cutting unit(s) when you store the lawn mower, unless you lock the cutting unit(s) into position.
