Standard Control Module (SCM) The Standard Control Module is a ”potted” electronic device produced in a ”one size fits all” configuration. The module uses solid state and mechanical components to monitor and control standard electrical features required for safe product operation. Output circuits are energized by an appropriate set of input conditions. The three outputs include PTO, ETR, and START.
– Indicates a circuit closed to ground. – LED ON O Indicates a circuit open to ground or de–energized – LED OFF + Indicates an energized circuit (clutch coil, solenoid, or start input) LED ON. ” ” A Blank indicates a circuit that is not involved with the logic. To troubleshoot, turn on the key without starting the engine. Identify the specific function that does not work and work across the logic chart. Inspect the condition of each input LED’s to ensure it matches the logic chart.
Operating Characteristics If a person appears in or near the operating area, stop the machine, and do not start it again until the area is cleared. The machine is designed for one person. Never let anyone else ride on the machine with you. This is extremely dangerous and could result in serious injury. Danger The slope angle at which the machine will tip is dependent on many factors.
Select the Proper Height-of-Cut Setting to Suit Conditions Remove approximately one inch or no more than 1/3 of the grass blade when cutting. In exceptionally lush and dense grass you may have to raise your height–of–cut setting another notch. Always Start Mowing with Sharp Blades A sharp blade cuts cleanly and without tearing or shredding the grass blades like a dull blade. Tearing and shredding causes the grass to turn brown at the edges which impairs growth and increases susceptibility to diseases.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule Maintenance Service Interval Maintenance Procedure After first 10 hours • Check the fan and alternator belt tension. • Replace the hydraulic filter. • Torque the wheel lug nuts. After first 50 hours • Change the engine oil and filter. • Check the engine RPM (at idle and full throttle). Inspect the air filter, dust cup, and burp valve. Lubricate all grease fittings.

Removing the Hood force dirt through the filter into the intake tract. This cleaning process prevents debris from migrating into the intake when the primary filter is removed. The hood may be easily removed to ease maintenance procedures in the engine area of the machine. 1. Unlatch and raise the hood. 2 2. Remove the cotter pin securing the hood pivot to the mounting brackets (Fig. 35). 1 1 Figure 36 1. Air cleaner cover Figure 35 2. Air cleaner latch 3. Remove and replace the primary filter (Fig.
Servicing the Engine Oil and Filter Servicing the Fuel System Change the oil and filter initially after the first 50 hours of operation; thereafter change the oil and filter every 150 hours. Drain and clean the fuel tank every 2 years. Also, drain and clean the tank if the fuel system becomes contaminated or if the machine will be stored for an extended period of time. Use clean fuel to flush out the tank. Fuel Tank 1. Remove either drain plug (Fig. 38) and let oil flow into a drain pan.
Replacing the Fuel Prefilter 4. Remove the clamp from the fuel filter and slide it onto the replacement filter. Push the fuel lines onto the replacement fuel filter and secure them with the hose clamps. Be sure that the arrow on the side of the filter points toward the injection pump. Replace the fuel prefilter, located on the inside of the frame rail below the water separator, after every 400 operating hours or yearly, whichever occurs first. 1. Remove the screw securing the filter to the frame rail. 5.
Alternator/Fan Belt 1. Turn the engine off and raise the hood. Clean the engine area thoroughly of all debris. 1. Open the hood. 2. Remove the access panel (Fig. 43). 2. Check the tension by depressing the belt midway between the alternator and crankshaft pulleys with 22 lb. (30 N⋅m) of force. The belt should deflect 7/16 in. (11 mm). If the deflection is incorrect, proceed to step 3. If it is correct, continue operation. 3 2 1 1 Figure 43 1. Access panel 2. Oil cooler 3. Radiator Figure 45 1.
7. If the throttle does not stay in position during operation, torque the locknut, used to set the friction device on the throttle lever, to 40–55 in.-lb. (5–6 N⋅m). The maximum force required to operate the throttle lever should be 20 lb. (27 N⋅m). 2 Changing the Hydraulic Fluid 1 Change the hydraulic fluid after every 400 operating hours, in normal conditions. If the fluid becomes contaminated, contact your local Toro distributor because the system must be flushed.
6. Start the engine and let it run for about two minutes to purge air from the system. Stop the engine and check for leaks. Important Use only the hydraulic fluids specified. Other fluids could cause system damage. Checking the Hydraulic Lines and Hoses 1 Daily, check hydraulic lines and hoses for leaks, kinked lines, loose mounting supports, wear, loose fittings, weather deterioration, and chemical deterioration. Make all necessary repairs before operating.
