Adding Fuel Note: Do not fill the fuel tank completely full. The empty space in the tank allows the fuel to expand. Recommended Fuel • For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method).
Using the Rollover-Protection System (ROPS) WARNING To avoid injury or death from rollover, keep the roll bar in the fully raised, locked position and use the seat belt. Ensure that the seat is secured to the machine. WARNING There is no rollover protection when the roll bar is in the down position.
Using the Safety-Interlock System WARNING If the safety-interlock switches are disconnected or damaged, the machine could operate unexpectedly, causing personal injury. • Do not tamper with the interlock switches. • Check the operation of the interlock g231781 Figure 11 switches daily and replace any damaged Smart hour meter shown switches before operating the machine.

Starting the Engine Shutting Off the Engine Important: Do not engage starter for more than 5 CAUTION seconds at a time. If the engine fails to start, wait 15 seconds between attempts. Failure to follow Children or bystanders may be injured if they these instructions can burn out the starter motor.
Using the Motion-Control WARNING Levers The machine can spin very rapidly. You may lose control of the machine and cause personal injury or damage to the machine. • Use caution when making turns. • Slow the machine down before making sharp turns.
Using the Side Discharge Machines with Side Discharge Only The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. DANGER Without a grass deflector, discharge cover, or a complete grass-catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris.
Adjusting the Height of Cut Adjusting the Height-of-Cut Pin The height-of-cut is adjusted from 25 to 140 mm (1 to 5-1/2 inches) in 6 mm (1/4 inch) increments by Using the Transport Lock relocating the clevis pin into different hole locations. The transport lock has 2 positions, and is used with Move the transport lock to the lock position.
Adjusting the Anti-Scalp Rollers Machines with Side Discharge Whenever you change the height-of-cut, adjust the height of the anti-scalp rollers. Park the machine on a level surface, disengage the blade-control switch, and engage the parking brake. g029957 Shut off the engine, remove the key, and wait Figure 31 for all moving parts to stop before leaving the 1.

Positioning the Flow Baffle Position B Use this position when bagging. Always align it with For Machines with Side Discharge the blower opening. The following figures are recommendations only. Adjustments vary by grass type, moisture content, and the height of the grass. Note: If the engine power draws down and the mower ground speed is the same, open the baffle.
Mowing at Correct Intervals Grass grows at different rates at different times of the year. To maintain the same cutting height, mow more often in early spring. As the grass growth rate slows in mid summer, mow less frequently. If you cannot mow for an extended period, first mow at a high cutting height, then mow again 2 days later at a lower height setting.

While the exposure from Toro products may be negligible or well within the “no significant risk” range, out of an abundance of caution, Toro has elected to provide the Prop 65 warnings. Moreover, if Toro does not provide these warnings, it could be sued by the State of California or by private parties seeking to enforce Prop 65 and subject to substantial penalties.
