Operation Note: Determine the left and right sides of the machine from the normal operating position. Checking the Engine Oil The engine is shipped with oil in the crankcase; however, the oil level must be checked before and after the engine is first started. Crankcase capacity is approximately 7.5 qt. (7 l) with the filter. Figure 17 Use high-quality engine oil that meets the following specifications: 1. Dipstick • API Classification Level Required: CH-4, CI-4 or higher. 3.
If the engine has been running, pressurized hot coolant can escape and cause burns if the radiator cap is removed. Allow the engine to cool at least 15 minutes or until the radiator cap is cool enough to touch without burning hands. 1. Carefully remove radiator cap and expansion tank cap (Figure 19). 2. Check level of coolant in radiator and in expansion tank (Figure 19). Figure 20 1. Radiator should be filled to the top of the filler neck and the expansion tank filled to the Full mark. Vent plug 4.
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. Biodegradable Hydraulic Fluid - Mobil 224H Toro Biodegradable Hydraulic Fluid (Available in 5 gallon pails or 55 gallon drums. See parts catalog or Toro distributor for part numbers.
Note: We recommend that anytime the machine is parked (short or long term) the cutting units should be lowered to the ground. This relieves pressure from the lift circuit and eliminates the risk of the cutting units accidentally lowering to the ground. 4. If level is low, add appropriate fluid to raise level to full mark. 5. Install dipstick and cap onto filler neck. Checking the Tire Pressure The tires are over-inflated for shipping. Therefore, release some of the air to reduce the pressure.
Pushing or Towing the Machine In an emergency, the machine can be moved by actuating the bypass valve in the variable displacement hydraulic pump and pushing or towing the machine. Important: Do not push or tow the machine faster than 2-3 mph (3-4.8 km/h) because internal transmission damage may occur. The bypass valve must be open whenever the machine is pushed or towed. Figure 23 1. Fuel lter/water separator 2. 1. The bypass valve is located on top of variable displacement pump (Figure 25).
Checking the Interlock Switches sure correct overlay decal is positioned on Diagnostic ACE display. If safety interlock switches are disconnected or damaged the machine could operate unexpectedly causing personal injury. • Do not tamper with the interlock switches. • Check the operation of the interlock switches daily and replace any damaged switches before operating the machine. • Replace switches every two years regardless of whether they are operating properly or not. Figure 27 1.
To verify output function: 1. Park machine on a level surface, lower the cutting units, stop the engine and engage the parking brake. 2. Open control panel cover.

Figure 34 Figure 37 • Rear axle pivot (Figure 35) Engine Maintenance Servicing the Air Cleaner Check the air cleaner body for damage which could cause an air leak. Replace if damaged. Check the whole intake system for leaks, damage or loose hose clamps. Service the air cleaner filter only when the service indicator (Figure 38) requires it. Changing the air filter before it is necessary only increases the chance of dirt entering the engine when the filter is removed.
Figure 39 1. Air cleaner latch 2. Figure 40 Air cleaner cover 1. Air cleaner primary lter 2. Remove the cover from the air cleaner body. Before removing the filter, use low pressure air (40 psi, clean and dry) to help remove large accumulations of debris packed between outside of primary filter and the canister. Avoid using high pressure air which could force dirt through the filter into the intake tract. Important: Never attempt to clean the safety filter (Figure 41).
Servicing the Engine Oil and Filter Change oil and filter initially after the first 50 hours of operation, thereafter change oil and filter every 150 hours. 1. Remove drain plug (Figure 42) and let oil flow into drain pan. When oil stops, install drain plug. Figure 44 1. Injection pump lever arm 2. Connector 3. Hold the injection pump lever arm against the high idle stop and tighten the cable connector. Note: When tightened, the cable connector must be free to swivel. 4.
Under certain conditions, diesel fuel and fuel vapors are highly flammable and explosive. A fire or explosion from fuel can burn you and others and can cause property damage. • Use a funnel and fill the fuel tank outdoors, in an open area, when the engine is off and is cold. Wipe up any fuel that spills. • Do not fill the fuel tank completely full. Add fuel to the fuel tank until the level is 1/4 to 1/2 in. (6 to 13 mm) below the bottom of the filler neck. This empty space in the tank allows the fuel to expand.
Note: Do not use water to clean engine, as damage may occur. Electrical System Maintenance Battery Care Warning Figure 47 1.
