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. Note: Determine the left and right sides of the machine from the normal operating position. Adding Fuel • Always place gasoline containers on the ground away from your vehicle before filling.
Filling the Fuel Tank Breaking In a New Machine 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. New engines take time to develop full power. Mower decks and drive systems have higher friction when they are new, placing additional load on the engine. Allow 40 to 50 hours of break-in time for new machines to develop full power and perform at their best performance. 1.
Think Safety First Please read all safety instructions and symbols in the safety section. Knowing this information could help you or bystanders avoid injury. DANGER Operating on wet grass or steep slopes can cause sliding and loss of control. Wheels dropping over edges can cause rollovers, which may result in serious injury, death or drowning. There is no rollover protection when the roll bar is down. Always keep the roll bar in the fully raised and locked position and use the seat belt.
Releasing the Parking Brake CAUTION This machine produces sound levels in excess of 85 dBA at the operators ear and can cause hearing loss through extended periods of exposure. 1 2 Wear hearing protection when operating this machine.

Transporting the Machine Loading Machines Use a heavy-duty trailer or truck to transport the machine. Ensure that the trailer or truck has all necessary brakes, lighting, and marking as required by law. Read all of the safety instructions. This information could help you, your family, pets, or bystanders avoid injury. Use extreme caution when loading units on trailers or trucks.
Mowing at Correct Intervals Normally, mow every 4 days. Grass grows at different rates at different times. So to maintain the same cutting height, which is a good practice, 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. Choosing the Cutting Speed To improve cut quality, use a slower ground speed in certain conditions.
Maintenance Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 100 hours • Check the wheel lug nut torque. • Check the wheel hub slotted nut torque. • Check the park brake adjustment.
