Handling Waste Product and Chemicals
Waste products, such as, used oil, fuel, coolant, brake fluid, and batteries, can harm the environment and people:

  • Do not use beverage containers for waste fluids - someone may drink from them.
  • See your local Recycling Center or authorized dealer to learn how to recycle or get rid of waste products.
  • A Material Safety Data Sheet (MSDS) provides specific details on chemical products: physical and health hazards, safety procedures, and emergency response techniques. The seller of the chemical products used with your machine is responsible for providing the MSDS for that product.

Adjusting Cutting Height
Cutting height can be adjusted from approximately 25 - 100 mm (1 - 4 in.) in 6.4 mm (1/4 in.) increments. When mower deck is in transport position, cutting height is approximately 100 mm (4 in.). Detents allow the adjustment lever to be positioned at each indicated mower setting, as well as the mid-point between each setting.

Adjusting Carburetor
NOTE: Carburetor is calibrated by the engine manufacturer and is not adjustable. If engine is operated at altitudes above 1829 m (6,000 ft), some carburetors may require a special high altitude main jet. See your authorized dealer. If engine is hard to start or runs rough, check the TROUBLESHOOTING section of this manual.

Possible engine surging will occur at high throttle with transmission in N neutral and mower engagement lever disengaged. This is a normal condition due to the emission control system. After performing the checks in the troubleshooting section and your engine is still not performing correctly, contact your authorized dealer.

Replacing Fuel Filter
NOTE: Change filter when fuel is low.

  1. Park machine safely. (See Parking Safely in the SAFETY section.)
  2. Let engine cool.
  3. Lift hood.
  4. Handle fuel safely. (See Handling Fuel Safely in the SAFETY section.)
  5. 5. Put a drain pan under fuel filter.

Service Miscellaneous
Using Proper Fuel
Use regular grade unleaded fuel with an octane rating of 87 octane or higher. Fuel blends containing up to 10% ethanol or up to 15% MTBE reformulated fuel are acceptable. Do not use fuel or additives containing methanol as engine damage can occur. Always use fresh, clean fuel that is purchased in a quantity that can be used within approximately 30 days, or add fuel stabilizer. Fuel is blended to give best seasonal performance. To avoid engine performance problems such as hard starting or vapor lock, use in-season fuel. Use fuel during warm weather that was purchased during that season, and use fuel during cold weather that was purchased during that season.

Fuel can become stale in machines with engines that are used seasonally or infrequently during a season. Stale fuel can produce varnish and plug carburetor components which can affect engine performance. Keep fuel storage container tightly covered and in a cool area out of direct sunlight. Fuel can break down and degrade if not sealed properly or exposed to sun and heat.

Condensation may collect in the fuel tank because of a variety of operating or environmental conditions and, over time, may affect your machine’s operation. Fill fuel tank at the end of daily use and store fuel in plastic containers to reduce condensation.

For best year-round performance and fuel-handling, add stabilizer to fuel immediately after fuel purchase. Such practice helps prevent engine performance problems and allows fuel storage in the machine all year without draining.
