Note: The machine is equipped with 8 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 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 fuses.

Release the cushion from the rear of the machine and remove the rear access cover to access the fuses.
