Recommended Fuel: Unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method) This space in the tank allows the fuel to expand. Do not fill the fuel tank completely full. 3. Ethanol: Gasoline with up to 10% ethanol (gasohol) or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable.
Slope Safety • Do not carry passengers on the machine and keep bystanders and children out of the operating area. • Slopes are a major factor related to loss of control • Operate the machine only in good visibility to avoid and rollover accidents, which can result in severe injury or death. You are responsible for safe slope operation. Operating the machine on any slope requires extra caution. holes or hidden hazards. • Avoid mowing on wet grass. Reduced traction could cause the machine to slide.
Breaking in the Machine Refer to the engine manual supplied with the machine for oil change and maintenance procedures recommended during the break-in period. 4. Only 8 hours of operation is required for the break-in period. 5. Since the first hours of operation are critical to future dependability of the machine, monitor its functions and performance closely so that minor difficulties, which could lead to major problems, are noted and can be corrected.
Correct the problem if it is not operating properly. The safety-interlock system prevents the engine from starting unless: • The traction pedal is in the NEUTRAL position. • The functional-control lever is in the NEUTRAL Checking the Operator’s Presence Switch position. The safety-interlock system prevents the machine from moving unless: • The parking brake is disengaged. • You are seated in the operator's seat. • The functional-control lever is in the MOW position 1.
Mowing the Green the outer edge of the steering wheel as part of the sight line; i.e., keep the steering wheel edge aligned with a point that is always kept the same distance away from the front of the machine. Important: If the leak detector alarm (if equipped on your model) sounds or you notice an oil leak while cutting on a green, immediately raise the cutting units, drive directly off the green, and stop the machine in an area away from the green.
4. Empty the grass baskets of all clippings before you transport the machine to the next green. Note: Heavy wet clippings place an undue strain on the baskets and add unnecessary weight to the machine, which increases the load on the machine systems (e.g., engine, hydraulic system, and brakes). After Operation After Operation Safety General Safety • Shut off the engine, remove the key (if equipped), g005116 Figure 24 1. Alignment strip 3. Cut grass on the left. 2.
