OPERATION
To start an engine with a weak 
battery
If your battery is too weak to start the engine, 
it should be recharged. (See "Battery" in the 
"Maintenance" section). 
If “jumper cables” are used for emergency 
starting, follow this procedure:
To attach jumper cables
Connect each end of the RED cable to 
the POSITIVE (+) terminal on each 
battery, taking care not to short against 
chassis.
Connect one end of the BLACK cable to 
the NEGATIVE (-) terminal of the fully 
charged battery.
Connect the other end of the BLACK 
cable to a good CHASSIS GROUND on 
the mower with the discharged battery, 
away from the fuel tank and battery.
To remove cables, reverse order
Remove BLACK cable first from chassis 
and then from the fully charged battery.
Remove RED cable last from both 
batteries.
WARNING!
Lead-acid batteries generate 
explosive gases. Keep sparks, 
flame and smoking materials 
away from batteries. Always 
wear eye protection when 
around batteries.
