Adjusting the Throttle

1. Position the throttle lever rearward so it stops against

the control panel slot.

2. Loosen the throttle cable connector on the injection

pump lever arm (Fig. 47).

3. Hold the injection pump lever arm against the low idle

stop and tighten the cable connector.

4. Loosen the screws securing the throttle control to the

control panel.

5. Push the throttle control lever all of the way forward.

6. Slide the stop plate until it contacts the throttle lever

and tighten the screws securing the throttle control to

the control panel.

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).

Changing the Hydraulic Fluid

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. Contaminated fluid looks milky or black when

compared to clean oil.

1. Turn the engine off and raise the hood.

2. Disconnect the hydraulic line (Fig. 48) or remove the

hydraulic filter (Fig. 49) and let the hydraulic fluid flow

into a drain pan. Install the hydraulic line when

hydraulic fluid stops draining.

3. Fill the reservoir (Fig. 50) with approximately 3.5 U.S.

gallons (13.2 l) of hydraulic fluid; refer to Checking the

Hydraulic System, page 17.
