Greasing the Traction Unit Note: After setup has been completed, remove protective edging (used for shipping) from fenders. Before the machine is operated, it must be greased to assure proper operating characteristics; refer to Lubrication Maintenance. Failure to grease the machine will result in premature failure of critical parts. Install Rear Weight To comply with ANSI/OPEI B71.4–1999 Standard, rear weight must be added to rear of traction unit. Use chart below to determine weight requirements.
3. If oil level is low, remove filler cap (Fig. 13) and add enough oil to raise level to top notch on dipstick. DO NOT OVERFILL. Before Operating Hood Prop 4. The engine uses any high–quality detergent oil having the American Petroleum Institute—API—“service classification” SG, SG/CC or SG/CD. Oil viscosity–weight– must be selected according to ambient temperature. Temperature/viscosity recommendations are: 1. Position the machine on a level surface. 2. Disengage hood latch and open the hood. 3.
1. Tip seat forward and prop it with the support rod so it cannot fall accidentally. Using a clean rag, clean area around fuel tank cap (Fig. 14). Filling the Fuel Tank THE TORO COMPANY STRONGLY RECOMMENDS THE USE OF FRESH, CLEAN, UNLEADED REGULAR GRADE GASOLINE IN TORO GASOLINE POWERED PRODUCTS. UNLEADED GASOLINE BURNS CLEANER, EXTENDS ENGINE LIFE, AND PROMOTES GOOD STARTING BY REDUCING THE BUILD–UP OF COMBUSTION CHAMBER DEPOSITS. LEADED GASOLINE CAN BE USED IF UNLEADED IS NOT AVAILABLE. 2.
Checking the Hydraulic System Fluid 2. Unscrew dipstick cap (Fig. 15) from the filler neck and wipe it with a clean rag. Screw dipstick cap finger tight onto filler neck. Unscrew the dipstick and check level of fluid. If level is not within 1/2 in. (13 mm) from the groove in the dipstick (Fig. 15), add enough fluid to raise level to groove mark. Do not overfill by more than 1/2 in. (13 mm) above groove. The front axle housing acts as the reservoir for the system.
Brake Pedal Operation Whenever the engine is shut off, the parking brake (Fig. 16) must be engaged to prevent accidental movement of the machine. Note: Determine the left and right sides of the machine from the normal operating position. The hydrostatic transmission will not, at any time, act as a parking brake for the machine. To engage parking brake, push down fully on brake pedal and pull parking brake knob out; then release the pedal.
5 3 2 1 4 7 6 8 1 11 10 Figure 17 9 1. Lift lever Figure 18 1. 2. 3. 4. 5. 6. PTO Lever The PTO lever (Fig. 18) has two positions: ON (engage) and OFF (disengage). Slowly push PTO lever fully forward to ON position to start the implement or cutting unit blades. Slowly, pull lever backward to OFF position to stop implement operation. The only time PTO lever should be in the ON position is when implement or cutting unit is down in operating position.
Starting/Stopping Engine The throttle regulates the speed of the cutter blades or other implement components and, in conjunction with traction pedal, controls ground speed of the traction unit. 1. Ensure parking brake is set, PTO switch is in OFF position and lift lever is in TRANSPORT or FLOAT position. Remove foot from traction pedal and insure it is in neutral. Choke To start a cold engine, close carburetor choke by moving choke control (Fig. 18) fully forward.
Checking the Interlock Switches Caution 5. Sit on seat. With parking brake engaged, engine running and PTO lever disengaged, depress the traction pedal. The engine should stop within 2-3 seconds. If the engine does not stop, there is a malfunction in the interlock system that should be corrected before beginning operation. If safety interlock switches are disconnected or damaged the machine could operate unexpectedly causing personal injury.
Operating Characteristics Use extra care when operating machine on slopes. Always have seat pivot retaining pin installed. Drive slowly and avoid sharp turns on slopes to prevent roll overs. The cutting deck must be lowered when going downhill for steering control. Practice driving the machine because it has a hydrostatic transmission and its characteristics are different than many turf maintenance machines.
