WARNING
Incorrect battery cable connections can damage the mower’s
electrical system and cause battery cables to spark. Sparks
around a battery can result in a battery gas explosion and
personal injury.
• Always disconnect negative (black) cable from battery
before disconnecting positive (red) cable.
• Always reconnect positive (red) cable to the battery’s
positive (+) post before reconnecting negative (black) cable
to the battery’s negative (-) post.
!
WARNING
Keep battery terminals from touching any metal mower parts
when removing or installing battery. Do not allow metal tools
to short between battery terminals and metal mower parts.
Shorts caused by battery terminals or metal tools touching
metal mower components can cause sparks. Sparks can cause
a battery gas explosion which can result in personal injury.

WARNING
Acid can cause serious injury to skin and eyes. Avoid skin
contact with battery acid and always wear eye protection
when checking the battery. Flush area with clean water and
