Gasoline and Oil Recommended Gasoline Use UNLEADED Regular Gasoline suitable for automotive use (85 pump octane minimum). Leaded regular gasoline may be used if unleaded regular is not available. POTENTIAL HAZARD • In certain conditions gasoline is extremely flammable and highly explosive. WHAT CAN HAPPEN IMPORTANT: Never use methanol, gasoline containing methanol, or gasohol containing more than 10% ethanol because the fuel system could be damaged. Do not mix oil with gasoline.
Gasoline and Oil Stabilizer/Conditioner Filling the Fuel Tank Add the correct amount of gas stabilizer/conditioner to the gas. Using a stabilizer/conditioner in the machine: 1. Shut the engine off and set the parking brake. 2. Clean around each fuel tank cap and remove the cap. Add unleaded regular gasoline to both fuel tanks, until the level is 1/4 to 1/2 inch (6 mm to 13 mm) below the bottom of the filler neck. This space in the tank allows gasoline to expand.

Operation Recyclerr Rider Tips Tips for Cutting Grass Recyclerr Rider Features Your Toro Recyclerr rider has a new and completely different cutting concept. It leaves your lawn with a bagged look without bagging clippings.The rider is equipped with special parts (Fig. NO TAG) which increase your rider’s ability to cut and recut grass clippings, leaves, and other yard debris into tiny particles which are injected down into the grass.
Operation • MOWING IN EXTREME CONDITIONS—Air is required to cut and recut grass clippings in rider housing, so do not set height-of-cut too low or totally surround housing by uncut grass. Always try to have one side of the rider housing free from uncut grass, allowing air to be drawn into housing. When making an initial cut thru center of uncut area, operate rider at a slower ground speed and back up if rider starts to clog.
Operation cover to the mower housing. NEVER REMOVE THE GRASS DEFLECTOR FROM THE MOWER HOUSING. • Overlap cutting swaths instead of cutting a full swath with each pass. • Mow across the marginal areas a second time. Tips For Cutting Leaves POTENTIAL HAZARD • Without the grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris.
