Corrective Action
1. Contact your Authorized Service
Dealer.
1. Replace the seals.
1. Charge the machine in conditions
between 2°C (35.6°F) and 55°C

Corrective Action
1. Ensure that the battery voltage is
correct and the cable connections are
secure; ensure that the battery is in
good condition.
1. Contact an Authorized Toro Dealer.
1. Possible causes include poor battery
health, very deeply discharged battery,
poorly connected battery, and/or
high parasitic loads on battery while
charging. Possible solutions: Replace
batteries. Check DC connections.
Disconnect parasitic loads. This error
will clear once the charger is reset by
cycling DC.
1. The battery is connected to the charger
incorrectly. Ensure that the battery
connections are secure.
1. Connect charger to an AC source that
provides stable AC between 85 - 270
VAC / 45-65 Hz.
