Note: The machine is equipped with at least 11 lithium-ion batteries. Batteries can be added with the appropriate energy expansion kits for this machine.

A lithium-ion battery must be disposed of or recycled in accordance with local and federal regulations. If a battery requires service, contact your authorized Toro distributor for assistance.

Do not open the battery. If you are having problems with a battery, contact your authorized Toro distributor for assistance

The lithium-ion batteries hold a sufficient charge to perform intended work during its life span.

To achieve maximum life and use from your batteries, follow these guidelines:

• Do not open the battery.

• Store/park the machine in a clean, dry garage or storage area, away from direct sunlight, heat sources, rain, and wet conditions. Do not store it in a location where the temperature exceeds the range specified in Battery Storage Requirements. Temperatures outside of this range can damage your batteries. High temperatures during storage, especially at a high state of charge, reduces the life of the batteries.

• When storing the machine for more than 10 days, ensure that the machine is in a cool and dry location, out of sunlight, rain, and wet conditions.

• If you are mowing in hot conditions or in sunlight, the battery may overheat. If this happens, a high-temperature alert will appear on the display. In this condition, the attachment (e.g., the cutting unit) is disengaged and the machine slows down.

  Immediately drive the machine to a cool location out of the sun, turn off the machine, and allow the batteries to cool fully before resuming operation.

• Maintain the sharpness of the mower blades. A dull blade increases power consumption and reduces the amount of work that the machine performs on each charge.

• Use lights only when it is necessary.

Important: All electrical repairs should be performed by an authorized Toro distributor only.

The charger requires little maintenance other than protecting it from damage and weather.

• Coil the power-supply cord when not in use.

• Periodically examine the cords for damage, and replace them when necessary with Toro-approved parts.

Note: The battery charger is enclosed below the operator’s seat.

Remove the seat-base plate (Figure 47) and remove any debris (e.g., grass) from the battery-charger compartment.

This fluid is compatible with the elastomers used in Toro hydraulic systems and is suitable for a wide-range of temperature conditions. This fluid is compatible with conventional mineral oils, but for maximum biodegradability and performance, the hydraulic system should be thoroughly flushed of conventional fluid. The oil is available in 19 L (5 US gallon) pails or 208 L (55 US gallon) drums from your authorized Toro distributor.

1. Park the machine on a level surface, lower the cutting unit, ensure that the parking brake is engaged, shut off the machine, and remove the key.

2. Raise the hood.

3. Remove the dipstick cap from the hydraulic tank and wipe it with a clean cloth (Figure 54).

   2. Lower fill mark

6. If the fluid level is below the appropriate lower mark on the dipstick, add the specified hydraulic fluid into the tank. Insert the dipstick cap into the tank and repeat steps 3 through 5 until the fluid level appears between the upper and lower marks (Figure 55) on the dipstick.

7. Insert the dipstick cap into the hydraulic tank and hand-tighten the cap.

8. Check all hydraulic hoses and fittings for leaks.

If the hydraulic fluid becomes contaminated, contact your authorized Toro distributor; the system must be flushed. Contaminated fluid looks milky or black when compared to clean fluid.

1. Park the machine on a level surface, lower the cutting unit, shut off the machine, and remove the key.

2. Place a large drain pan under the hydraulic-fluid pump.

3. Remove the hydraulic-tank dipstick cap.

4. Perform the following steps to drain the hydraulic fluid from the tank:

   1. Remove the hose and hose clamp from the pump (Figure 56).

      2. Hose clamp
      3. Hose

   2. Allow the hydraulic fluid to drain from the hose into the drain pan (Figure 56).

   3. Use the hose clamp to secure the hose to the pump.

5. Fill the hydraulic tank with hydraulic fluid. For specifications, refer to Hydraulic Fluid Specifications.

   Important: Use only the hydraulic fluids specified. Other fluids could cause system damage.

6. Install the hydraulic-tank cap dipstick.

7. Start the machine and use all of the hydraulic controls in the following order to distribute hydraulic fluid throughout the system:

   1. Use the steering wheel to move the tires all the way to the right and left.

   2. Use the lift switch to raise and lower the cutting unit.

8. Check for leaks and shut off the machine.

9. Check the hydraulic fluid level in the tank; refer to Checking the Hydraulic-Fluid Level.

Important: Use the appropriate Toro hydraulic filter; refer to the machine Parts Catalog. Using any other filter may void the warranty on some components.

1. Clean the area around the hydraulic-filter mounting area (shown in Figure 57).

2. Place a drain pan under the filter, remove the filter, and let any remaining oil drain into the pan.

3. Lubricate the new filter gasket and fill the filter with hydraulic fluid.

4. Ensure that the filter-mounting area is clean and screw the filter on until the gasket contacts the mounting plate; then tighten the filter an additional 1/2 turn.

Inspect the hydraulic lines and hoses daily for leaks, kinked lines, loose mounting supports, wear, loose fittings, weather deterioration, and chemical deterioration. Make all necessary repairs before operating the machine.

1. Park the machine on a level surface, shut off the machine, remove the key; and wait for all movement to stop before leaving the machine.

2. Turn the battery-disconnect switch to the OFF position.

3. Clean debris from the machine using water alone or with a mild detergent. You may use a rag when washing the machine. You may also use compressed air.

   Warning

   Using compressed air improperly to clean the machine could result in serious injury.

   • Wear appropriate personal protective equipment, such as eye protection, hearing protection, and a dust mask.

   • Do not aim compressed air at any part of your body or at anyone else.

   • Refer to the manufacturer’s instructions for the air compressor for operating and safety information.

Important: Do not use brackish or reclaimed water to clean the machine.

Important: Do not spray electrical components directly with water, as this may damage the electrical system.

Important: Pressurized water is not recommended when washing the machine. It may damage the electrical system, loosen important decals, or wash away necessary grease at friction points. Avoid excessive use of water, especially near any electrical components or connections.
