Danger signals an extreme hazard that will cause serious injury or death if the recommended precautions are not followed. • Ensure that the area is clear of other people before operating the traction unit. Stop the traction unit if anyone enters the area. Warning signals a hazard that may cause serious injury or death if the recommended precautions are not followed. • Never carry passengers on attachments or on the traction unit.
• Do not park the traction unit on a hillside or slope without lowering the attachment to the ground and chocking the wheels. Slope Operation Slopes are a major factor related to loss-of-control and tip-over accidents which can result in severe injury or death. All slopes require extra caution. • Do not try to stabilize the traction unit by putting your foot on the ground.
• Never store the traction unit or fuel container inside where there is an open flame, such as near a water heater or furnace. • Never fill a container while it is inside a vehicle, trunk, pick-up bed, or any surface other than the ground. • Keep container nozzle in contact with the tank during filling. • Stop and inspect the equipment if you strike an object. Make any necessary repairs before restarting. • Use only genuine replacement parts to ensure that original standards are maintained.

Lower part of the tube 3 6. Leave the covers off and connect a 3 to 4 amp battery charger to the battery posts (Fig.
8. When the battery is fully charged, disconnect the charger from the electrical outlet and from the negative and positive battery posts (Fig. 5). Specifications and design are subject to change without notice. 9. Slowly pour electrolyte into each cell until the level is once again up to the upper line on the battery case (Fig. 4) and install the covers. Attachments Many attachments are available for use with the traction unit.
Stability Data The following table lists the maximum slope recommended for the traction unit in the positions listed in the table. Slopes over the listed degree may cause the traction unit to become unstable. The data in the table assumes that the loader arms are fully lowered and that the factory installed tires are on the traction unit, inflated to the recommended pressure; raised arms and other tire types or pressure may affect the stability.
Adding Fuel Draining Water from the Fuel Filter Danger Drain water or other contaminants from the fuel filter daily. In certain conditions, fuel is flammable and explosive. A fire or explosion can burn you and others and can damage property. 1. Stop the engine and remove the key. 2. Open the rear access cover; refer to Opening the Rear Access Cover, page 25. • Fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any fuel that spills.

Key Switch Loader Valve Lock The key switch, used to start and stop the engine, has three positions: stop, run, and start. The loader valve lock secures the loader arm and attachment tilt levers so that you cannot push them forward. This helps to ensure that no one will accidentally lower the loader arms during maintenance. Secure the loader arms with the lock anytime you need to stop the machine with the loader arms raised. To start the engine, rotate the key to the start position.
the more hydraulic flow you divert to the auxiliary hydraulics, the slower the traction unit hydraulics will move. Move the speed selector lever to the slow (turtle) position to set the auxiliary hydraulics to high speed and the traction drive, loader arms, and attachment tilt to low speed. 1 Warning 2 If you move the speed selector lever while the traction unit is in motion, the traction unit will either stop suddenly or accelerate quickly.
Parking Brake and allow the traction unit to cool down. Check the oil level and fill the crankcase with oil as needed. If the problem persists, contact your Authorized Toro Dealer for diagnostics and repair. The traction unit is equipped with a parking brake (Fig. 15). Rotate the brake lever downward to set the brake to lock the rear wheels whenever the traction unit will be stopped on a hill or left unattended. Move the lever up before driving the traction unit.
Stopping the Engine Moving a Non-functioning Traction Unit 1. Move the throttle lever to the slow (turtle) position. 2. Lower the loader arms to the ground. Important Do not tow or pull the traction unit without first opening the tow valves, or the hydraulic system will be damaged 3. Turn the ignition key to the stop position. Note: If the engine has been working hard or is hot, let it idle for a minute before stopping it. This helps to cool the engine.
Installing the Cylinder Locks 1 1. Start the engine. 2. Raise the loader arms to the fully raised position. 3 4 2 1 3. Stop the engine. 2 4. Position a loader arm cylinder lock over each lift cylinder rod (Fig. 18). 5. Secure each loader arm cylinder lock with a clevis pin and cotter pin (Fig. 18). m–4601 Figure 19 5 1 1.

Connecting the Hydraulic Hoses 5. Raise the loader arms while tilting back the mount plate at the same time. If the attachment requires hydraulics for operation, connect the hydraulic hoses as follows: Important The attachment should be raised enough to clear the ground, and the mount plate should be tilted all the way back. 1. Stop the engine. 2. Move the auxiliary hydraulics lever forward, backward, and back to neutral to relieve pressure at the hydraulic couplers. 6. Stop the engine. 7.
Removing an Attachment Securing the Traction Unit for Transport 1. Lower the attachment to the ground 2. Stop the engine. When transporting the traction unit on a trailer, always use the following procedure: 3. Disengage the quick attach pins by turning them to the outside. Important roadways. 4. If the attachment uses hydraulics, move the auxiliary hydraulics lever forward, backward, and back to neutral to relieve pressure at the hydraulic couplers. Do not operate or drive the traction unit on 1.
