Auxiliary Hydraulics Lever Note: The farther you move the traction control levers in either direction, the faster the traction unit will move in that direction. • To operate a hydraulic attachment in forward direction, slowly pull the auxiliary hydraulics lever upward and then rearward. • To operate a hydraulic attachment in reverse direction, slowly pull the auxiliary hydraulics lever upward and then push it forward. This is also called the detent position because it does not require operator presence.
Flow Divider Control Parking Brake The traction unit hydraulics (i.e., the traction drive, loader arms, and attachment tilt) work on a separate hydraulic circuit from the auxiliary hydraulics for powering attachments; however, the two systems share the same hydraulic pumps. Using the flow divider control (Figure 10), you can vary the speed of the traction unit hydraulics by diverting hydraulic flow to the auxiliary hydraulics circuit.
oil as needed. If the problem persists, contact your Authorized Toro Dealer for diagnostics and repair. This light is on when the key is turned to run before starting the engine. The glow plug light will remain on for up to 10 seconds, indicating that the glow plugs are warming the engine. If the glow plug light is on while the engine is running, the glow plugs are broken. Contact your Authorized Toro Dealer for diagnostics and repair.
Stability Data The following tables list the maximum slope recommended for the traction unit in the positions listed in the tables. Slopes over the listed degree may cause the traction unit to become unstable. The data in the tables assume that the loader arms are fully lowered; raised arms may affect the stability. In each attachment manual is a set of three stability ratings, one for each hill position.
Operation Note: Determine the left and right sides of the machine from the normal operating position. Important: Before operating, check the fuel, oil, and coolant level; remove debris from the traction unit; test the parking brake, and check the tire pressure. Also, ensure that the area is clear of people and debris. You should also know and have marked the locations of all utility lines. You could fall off of the platform and be seriously injured during operation.
3. Turn the drain valve until the water runs out of the filter (Figure 13). 9. Slowly pour only enough oil (diesel engine oil, API service CH-4, CI-4, or higher; refer to Servicing the Engine Oil in Maintenance) into the valve cover to raise the level to the upper mark on the dipstick. Note: The fuel filter is located near the bottom of the fuel tank. Important: Do not overfill the crankcase with oil because the engine may be damaged. 10. Replace the filler cap and dipstick.
Important: Do not over fill the radiator. 4. Remove the front access cover. 5. Replace the radiator filler cap, ensuring that it is tightly sealed. 5. Clean the area around the filler neck of the hydraulic tank (Figure 16). 6. Remove the cap from the filler neck and check the fluid level on the dipstick (Figure 16). Removing Debris from the Traction Unit The fluid level should be between the marks on the dipstick.
Checking the Tire Pressure freezing or lower), hydraulic system damage could occur. When starting the engine in cold conditions, allow the engine to run in the middle throttle position for 2 to 5 minutes before moving the throttle to fast (rabbit). Service Interval: Before each use or daily Maintain the air pressure in the tires as specified. Check the tires when they are cold to get the most accurate reading.
Using the Cylinder Locks A child or untrained bystander could attempt to operate the traction unit and be injured. The loader arms may lower when in the raised position crushing anyone under them. Remove the key from the switch when leaving the traction unit, even if just for a few seconds. Install the cylinder locks before performing maintenance that requires raised loader arms.
Important: The attachment should be raised enough to clear the ground, and the mount plate should be tilted all the way back. 6. Stop the engine. 7. Engage the quick attach pins, ensuring that they are fully seated in the mount plate (Figure 23). Important: If the pins do not rotate to the engaged position, the mount plate is not fully aligned with the holes in the attachment receiver plate. Check the receiver plate and clean it if necessary.
