MAINTENANCE
Battery
Your mower is equipped with a maintenance free 
battery and does not need servicing. However, 
periodic charging of the battery with an automotive 
type battery charger will extend its life.
•  Keep battery and terminals clean.
•  Keep battery bolts tight.
•  See chart for charging times.
IMPORTANT INFORMATION
Do not attempt to open or remove caps or 
covers. Adding or checking level of electrolyte 
is not necessary.
Always use two wrenches for the terminal 
screws.
WARNING!
Do not short battery terminals by 
allowing a wrench or any other object 
to contact both terminals at the same 
time. Before connecting battery, 
remove metal bracelets, wristwatch 
bands, rings, etc.
Positive terminal must be connected 
first to prevent sparks from accidental 
grounding.
