Operation DANGER In certain conditions during fueling, static electricity can cause 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. • Do not fill gasoline containers inside a vehicle or on a truck or trailer bed, because interior carpets or plastic truck-bed liners may insulate the container and slow the loss of any static charge.
Add the correct amount of fuel stabilizer/conditioner to the fuel, and follow the directions of the manufacturer. Filling the Fuel Tank Note: Fuel stabilizer/conditioner is most effective fuel tank to the bottom of the filler neck. The empty space in the tank allows the gasoline to expand. Note: Do not fill the fuel tank completely full. Fill the when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times. 1.
Checking the Engine-Oil Level Before you start the engine and use the machine, check the oil level in the engine crankcase; refer to Servicing the Engine Oil (page 39). Breaking in a New Machine New engines take time to develop full power. Mower decks and drive systems have higher friction when new, placing additional load on the engine. Allow 40 to 50 hours of break-in time for new machines to develop full power and best performance.
DANGER CAUTION Operating the machine on wet grass or steep slopes can cause sliding and loss of control. • Do not operate on slopes greater than 15 degrees. This machine produces sound levels in excess of 85 dBA at the operator’s ear and can cause hearing loss through extended periods of exposure. • Reduce speed and use extreme caution on slopes. Wear hearing protection when operating this machine. • Do not operate the machine near water.
