Before Operating Caution If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders. 1 Remove the key from the ignition before you do any maintenance. Figure 5 1. Oil fill cap Checking the Engine Oil 5. The engine uses any high-quality detergent oil having the American Petroleum Institute (API) “service classification” CD, CE, CF, CF-4, or CG-4.
Caution If the engine has been running, the pressurized, hot coolant can escape and cause burns. • Do not open the radiator cap when the engine is running. • Use a rag when opening the radiator cap, and open the cap slowly to allow steam to escape. 1 2. Check the coolant level in the radiator. The radiator should be filled to the top of the filler neck and the expansion tank filled to the FULL mark. Figure 7 1. Fuel tank cap 2.
Checking the Hydraulic Fluid Mobil. Contact your local Toro Distributor for details. This oil is available in 5 gallon (19 l) containers from your Toro Distributor, order part no. 100–7674. The machines reservoir is filled at the factory with approximately 7.5 gallons of high quality hydraulic fluid. Check the level of hydraulic fluid before the engine is first started and daily thereafter. Appropriate hydraulic oils are listed below. 1.
2. Remove a check plug from one end of the axle (Fig. 11) and make sure that the lubricant is up to the bottom of the hole. If the level is low, remove the fill plug (Fig. 11) and add enough lubricant to bring the level up to the bottom of the check plug holes. 1 2 1 Figure 9 Figure 11 1. Check/drain plug 1. Check plug 2. Remove the plug on the planetary (Fig. 9) and the check plug on the back side of the brake (Fig. 10).
Forward Speed Control Operation Preset the forward speed control (Fig. 12) to limit the amount the traction pedal can be depressed in the forward direction to maintain a constant mowing speed. Note: Determine the left and right sides of the machine from the normal operating position. Caution Key Switch The key switch (Fig. 12) has three positions: Off, On/Preheat, and Start.
Brake Pedals Engine Temperature Gauge Two foot pedals (Fig. 14) operate individual wheel brakes for turning assistance, parking, and to aid in obtaining better side hill traction. A latch connects the pedals for parking brake operation and transport. This gauge (Fig. 15) indicates the engine coolant temperature. Pedal Locking Latch The PTO switch (Fig. 15) has two positions: On (engage) and Off (disengage). Push the PTO switch forward to the On position to start the implement or cutting unit blades.
1. Remove your foot from the traction pedal and ensure that it is in neutral. Ensure that the parking brake is set. 2. Move the throttle control to the low idle position. 3. Turn the ignition key to the Run position. The glow indicator will light. 4. When the glow indicator dims, turn the ignition key to the Start position. Release the key immediately when the engine starts and allow it to return to the Run position. Move the throttle control to the desired position. 1 Figure 16 1.
Checking the Interlock Switches Danger 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. Caution If safety interlock switches are disconnected or damaged the machine could operate unexpectedly causing personal injury. • 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.
Pushing or Towing the Machine Tie Downs In an emergency, the machine can be moved forward by actuating the bypass valve in the variable displacement hydraulic pump and pushing or towing the machine. Do not push or tow the machine for more than 1/4 mile (0.4 km). • On each side of the frame under the front steps • The rear bumper Operating Characteristics Important Do not push or tow the machine faster than 2–3 MPH (3–4.8 km/h) because internal transmission damage may occur.
High Lift Parallel Sail Important Allow engine to idle for 5 minutes before shutting it off after a full load operation. Failure to do so may lead to turbo–charger trouble. The blade generally performs better in the higher heights of cut (2 to 4 inch). Before stopping the engine, disengage all controls and move the throttle to Slow. Moving the throttle to Slow reduces high engine RPM, noise, and vibration. Turn the key to Off to stop the engine. Attributes: • More lift and higher discharge velocity.
