Operation DANGER In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property. • Always place gasoline containers on the ground away from your vehicle before filling.
Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times. Filling the Fuel Tank G009189 Note: Do not fill the fuel tank completely full. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows the gasoline to expand. Overfilling may result in fuel leakage or damage to the engine or emission system (if equipped). 1 1.
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 the seat is secured to the machine. WARNING There is no rollover protection when the roll bar is in the down position. • Lower the roll bar only when absolutely necessary. • Do not wear the seat belt when the roll bar is in the down position. • Drive slowly and carefully. • Raise the roll bar as soon as clearance permits.
DANGER CAUTION Operating on wet grass or steep slopes can cause sliding and loss of control. This machine produces sound levels in excess of 85 dBA at the operators ear and can cause hearing loss through extended periods of exposure. Wheels dropping over edges can cause rollovers, which may result in serious injury, death or drowning. Wear hearing protection when operating this machine. There is no rollover protection when the roll bar is down.

between the rear wheels and serves as a stop for tipping backward. Having a full width ramp provides a surface for the frame members to contact if the unit starts to tip backward. If it is not possible to use one full width ramp, use enough individual ramps to simulate a full width continuous ramp. The ramp should be long enough so that the angles do not exceed 15 degrees (Figure 38). A steeper angle may cause mower components to get caught as the unit moves from ramp to trailer or truck.
Mowing Direction shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease. Check the cutter blades daily for sharpness, and for any wear or damage. File down any nicks and sharpen the blades as necessary. If a blade is damaged or worn, replace it immediately with a genuine TORO replacement blade. Alternate mowing direction to keep the grass standing straight.
