Refer to the main information screen in the InfoCenter to determine the battery-system charge level.

• Low battery: When the battery level reaches a low percentage, a low-battery advisory appears on the InfoCenter.

  Finish mowing, then transport the machine to a designated battery-charging area and charge the batteries.

• Limp mode: If the battery level drops below the set limp-mode battery percentage, an advisory appears on the InfoCenter, and the mower blades will disengage and cannot be engaged.

  Transport your machine to a designated battery-charging area and charge the batteries.

• Ultra-limp mode: If the battery level becomes too low during limp mode, an advisory appears on the InfoCenter and traction speed automatically decreases.

  Transport your machine to a designated battery-charging area and charge the batteries.

Refer to Charging the Lithium-Ion Batteries.

Important: Do not tow the machine without first disengaging the transmission, otherwise you could damage motor components.

1. Disengage the PTO and move the motion-control levers outward to the PARK position.

2. Shut off the machine, remove the key, and wait for all moving parts to stop before leaving the operating position.

Use a heavy-duty trailer or truck to transport the machine. Use a full-width ramp. Ensure that the trailer or truck has all the necessary brakes, lighting, and marking as required by law. Please carefully read all the safety instructions. Knowing this information could help you or bystanders avoid injury. Refer to your local ordinances for trailer and tie-down requirements.

The US Department of Transportation and international transportation authorities require that lithium-ion batteries be transported using special packaging and only be transported by carriers certified to haul them. In the US, you are allowed to transport a battery when it is installed on the machine as battery powered equipment, with some regulatory requirements. Contact the US Department of Transportation or the appropriate government body in your country for detailed regulations on transportation of your batteries or the machine with the batteries equipped.

For detailed information on shipping a battery, contact your Authorized Service Dealer.

Refer to Figure 52 for an overview of the battery-charger cords.

   Figure 59

   1. Seal guard
   2. Spacer nut with wrench flats

5. Remove 1 spacer nut from the axle assembly in the caster wheel.

   Note: Thread-locking adhesive has been applied to lock the spacer nuts to the axle.

6. Remove the axle with the other spacer nut still assembled to it from the wheel assembly.

7. Pry out the seals, inspect bearings for wear or damage, and replace them if necessary.

8. Pack the bearings with a general-purpose grease.

9. Insert 1 bearing and 1 new seal into the wheel.

   Note: You must replace the seals.

10. If both spacer nuts in the axle assembly have been removed (or broken loose), apply thread-locking adhesive to 1 spacer nut, threading it onto the axle with the wrench flats facing outward.

    Note: Do not thread the spacer nut all of the way onto the end of the axle. Leave approximately 3 mm (1/8 inch) from the outer surface of the spacer nut to the end of the axle inside the nut.

11. Insert the assembled nut and axle into the wheel on the side of the wheel with the new seal and bearing.

12. With the open end of the wheel facing up, fill the area inside the wheel around the axle full of general-purpose grease.

13. Insert the second bearing and the new seal into the wheel.

14. Apply thread-locking adhesive to the second spacer nut, threading it onto the axle with the wrench flats facing outward.

15. Torque the nut to 8 to 9 N∙m (71 to 80 in-lb), loosen it, then torque it to 2 to 3 N∙m (20 to 25 in-lb).

    Note: Make sure that the axle does not extend beyond either nut.

16. Install the seal guards over the wheel hub and insert the wheel into the caster fork.

17. Install the caster bolt and tighten the nut fully.

Important: To prevent seal and bearing damage, check the bearing adjustment often by spinning the caster wheel. The wheel should not spin freely (more than 1 or 2 revolutions) or have any side play. If the wheel spins freely, adjust the torque on the spacer nut until there is a slight amount of drag, then apply thread-locking adhesive.

1. Park the machine on a level surface, disengage the PTO, and move the motion-control levers outward to the PARK position.

2. Shut off the machine, remove the key, and wait for all moving parts to stop before leaving the operating position.

3. Unplug the battery charger if it is connected.

4. Position the battery disconnect switch to electrically de-energize or energize the machine.

   

   Figure 60

   1. Turn the switch to the OFF position to de-energize the machine electrically.
   2. Turn the switch to the ON position to energize the machine electrically.

Note: The machine is equipped with 10 lithium-ion batteries.

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 Service Dealer for assistance.

Do not open the main compartment of a battery. If you are having problems with a battery, contact your Authorized Service Dealer 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 will 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 strong, direct sunlight, the battery may overheat. If this happens, a high-temperature alert will appear on the InfoCenter, the cutting units will disengage, and the machine will slow 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 Dealer only.

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

• Clean the battery-charger cords and case with a slightly damp cloth after each use.

  Note: Do not clean the dielectric grease from the terminals.

• Coil the cords when not in use.

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

The electrical system is protected by fuses. It requires no maintenance. Refer to the Service Manual for information on testing and servicing the motor fuses.

Remove the rear cover to access the fuses.

Inspect the seat belt for wear, cuts, and proper operation of the retractor and buckle. Replace the seat belt if it is damaged.

Maintain the air pressure in the rear tires at 83 to 97 kPa (12 to 14 psi).

Important: Uneven tire pressure can cause an uneven cut.

Note: The front tires are semi-pneumatic tires and do not require air-pressure maintenance.
