CAUTION 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.
WARNING Fuel is harmful or fatal if swallowed. Long-term exposure to vapors can cause serious injury and illness. • Avoid prolonged breathing of vapors. • Keep face away from nozzle and fuel tank or conditioner opening. • Keep fuel away from eyes and skin. Biodiesel Ready This machine can also use a biodiesel blended fuel of up to B20 (20% biodiesel, 80% petrodiesel). The petrodiesel portion should be low or ultra low sulfur.
DANGER DANGER In certain conditions, fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn you and others and can damage property. • Use a funnel and fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any fuel that spills. • Never fill the fuel tank inside an enclosed trailer. • Do not fill the fuel tank completely full. Add fuel to the fuel tank until the level is 25 mm (1 inch) below the top of the tank, not the filler neck.

Stopping the Engine Mow Speed Important: Allow the engine to idle for 5 minutes before shutting it off after a full load operation. This allows the turbo charger to cool down before shutting the engine off. Failure to do so may lead to turbo-charger trouble. Supervisor (Protected Menu) Note: Lower the cutting units to the ground whenever Refer to Using the InfoCenter LCD Display, in the Operation section of this manual, for the procedure to set the mow speed.
malfunction in the interlock system that should be corrected before beginning operation. During different times of the mowing season or when turf conditions vary, the amount of counterbalance (upward lift) required on the cutting decks can be changed to meet the conditions. Pushing or Towing the Machine Refer to Using the InfoCenter LCD Display, in the Operation section of this manual, for the procedure to set the counterbalance pressure.
However, use them carefully, especially on soft or wet grass because the turf may be torn accidentally. Another benefit of the brakes is to maintain traction. For example, in some slope conditions, the uphill wheel slips and loses traction. If this situation occurs, depress the uphill turn pedal gradually and intermittently until the uphill wheel stops slipping, thus, increasing traction on the downhill wheel. Use extra care when operating the machine on slopes.
Mow at Proper Intervals Under most normal conditions you will need to mow approximately every 4-5 days. But remember, grass grows at different rates at different times. This means that in order to maintain the same height-of-cut, which is a good practice, you will need to cut more frequently in early spring; as the grass growth rate slows in mid summer, cut only every 8-10 days.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 8 hours • Torque the wheel nuts. After the first 200 hours Before each use or daily • Change the planetary gear drive oil. • Change the rear axle lubricant. • Change the hydraulic filters. • • • • • • • • • Check the engine oil level.
