Charging the Battery Important: Do not add electrolyte while the battery is in the machine. You could spill it, causing corrosion. 2. 1. Connect a 3 to 4 A battery charger to the battery posts. Charge the battery at a rate of 3 to 4 amps until the specific gravity of the electrolyte is 1.250 or higher and the temperature of the battery is at least 16°C (60°F), with all cells freely discharging gas. 2.
• Check the level of the rear-axle lubricant (4-wheel WARNING drive machines only) before the engine is first started; refer to Maintaining the Rear Axle (page 54). Incorrect battery cable routing could damage the machine and cables, causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury. • Check the level of the bidirectional clutch lubricant (4-wheel drive machines only) before the engine is first started; refer to Maintaining the Bidirectional Clutch (page 55).
10 Adjusting the Weight Transfer of the Mower Deck No Parts Required Procedure g034107 Figure 13 You can change the hydraulic pressure used to transfer the weight of the mower deck to the traction unit by adjusting weight-transfer valve of the lift manifold. For best cutting performance, adjust the weight-transfer valve so that any bouncing motion of the mower deck is minimal over uneven turf, but also adjust the weight-transfer valve so that the mower deck does not ride heavily over flat terrain. 3.

Right-brake pedal Service Brakes g001210 Figure 17 The left and right brake pedals (Figure 18) are connected to the left and right front wheels. Since both brakes work independently of each other, you can use the brakes to turn sharply or to increase traction if 1 wheel tends to slip while operating on certain slope conditions.

Moving the throttle lever rearward toward the SLOW position decreases the engine speed.
Charge Indicator The charge indicator illuminates if electrical charging system is operating above or below the normal operating range (Figure 20). Check and/or repair the electrical charging system. Oil-Pressure Warning Light The oil-pressure warning light glows if the engine-oil pressure drops below a safe level (Figure 20). If the oil pressure is low, shut off the engine and determine the cause. Repair the engine-oil system before you start the engine again.

Checking the Machine Daily Checking the Interlock Check the following machine systems each day System before operating the machine: Service Interval: Before each use or daily • Air Cleaner Indicator; refer to Checking the Air Cleaner Indicator (page 45) The purpose of the safety interlock system is to prevent the engine from cranking or starting unless the traction pedal is in neutral and the PTO switch is in the OFF position.
Filling the Fuel Tank should shut off within 2 seconds. If engine shuts off, the switch is operating correctly; the interlock system is ready for machine operation. Note: If possible, fill the fuel tank after each use; this minimizes possible buildup of condensation inside the fuel tank. Important: If engine does not shut off, there is a malfunction in the safety-interlock system. Adding Fuel Use only clean, fresh diesel fuel or biodiesel fuels with low (<500 ppm) or ultra low (<15 ppm) sulfur content.
Adjusting the Roll Bar WARNING To avoid injury or death from rollover: keep the roll bar in the raised locked position and use the seat belt. g034169 Ensure that the seat is secured with the seat latch. WARNING There is no rollover protection when the roll bar is in the down position. • Do not operate the machine on uneven ground or on a hill side with the roll bar in the down position. • Lower the roll bar only when absolutely necessary.

Open the air-bleed screw on the fuel-injection pump (Figure 31). Operating Tips • Practice driving before operating the machine, because it has a hydrostatic transmission and its characteristics are different than some turf-maintenance machines.
After Operation After Operation Safety • Clean grass and debris from the cutting units, mufflers, and engine compartment to help prevent fires. Clean up oil or fuel spills. • If the cutting units are in the transport position, use the positive mechanical lock (if available) before you leave the machine unattended. • Allow the engine to cool before storing the machine in any enclosure. • Remove the key and shut off the fuel (if equipped) before storing or transporting the machine.
Hauling the Machine • Remove the key and shut off the fuel (if equipped) before storing or transporting the machine. • Use care when loading or unloading the machine into a trailer or a truck. • Use full-width ramps for loading the machine into a trailer or a truck. • Tie the machine down securely. g035503 Figure 33 1.
