Operation 1. Park the machine on a level surface. 2. Unlock the engine cover latches and open the engine cover. 3. Remove the dipstick, wipe it clean, install the dipstick into the tube, and pull it out again. Note: Determine the left and right sides of the machine from the normal operating position. CAUTION The oil level should be in the safe range (Figure 14).
Filling the Fuel Tank Checking the Cooling System Use only clean, fresh diesel fuel or biodiesel fuels with low (<500 ppm) or ultra low (<15 ppm) sulfur content. The minimum cetane rating should be 40. Purchase fuel in quantities that can be used within 180 days to ensure fuel freshness. Service Interval: Before each use or daily Check level of coolant at the beginning of each day. Capacity of system is 13 qt. (12.3 l). 1. Fuel tank capacity: 22 gallons (83 l). Carefully remove the radiator cap.
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 1 in. (25 mm) below the top of the tank, not the filler neck.
5. Industry Specifications: Vickers I-286-S (Quality Level), Vickers M-2950-S (Quality Level), Denison HF-0 Install the dipstick and cap onto the filler neck. Checking the Tire Pressure Note: Many hydraulic fluids are almost colorless, making it difficult to spot leaks. A red dye additive for the hydraulic system oil is available in 2/3 oz. (20 ml) bottles. One bottle is sufficient for 4-6 gal (15-22 1) of hydraulic oil. Order part no. 44-2500 from your authorized Toro distributor.
Stopping the Engine not crank. If the engine cranks, there is a malfunction in the interlock system that should be corrected before beginning operation. Important: Allow 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. Note: Lower cutting units to the ground whenever machine is parked.
Another characteristic to consider is the operation of the pedals that are connected to the brakes. The brakes can be used to assist in turning the machine. 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.
counterbalance pressure transfers cutting deck weight to the mower's drive wheels to improve traction. The counterbalance pressure has been factory set to an optimal balance of aftercut appearance and traction capability in most turf conditions. Decreasing the counterbalance setting can produce a more stable cutting deck, but can decrease the traction capability. Increasing the counterbalance setting can increase the traction capability, but may result in aftercut appearance issues.
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 50 hours • Change the engine oil and filter. After the first 200 hours • Change the planetary gear drive oil. • Change the rear axle lubricant. • Change the hydraulic filters.
