Battery Care & Charging Before charging the battery pack, read all instructions and cautionary markings in this manual and on your mower. Do not operate your mower until you have read and understand all instructions and the battery pack has been fully charged. Battery Pack ®...
Initial Charging IMPORTANT! The battery pack in your mower has been charged at the factory. However, you must recharge the battery pack and make sure it is fully charged before initial operation of the mower. Failure to do so may cause permanent damage to the battery pack.
· When the charging is complete, after about 12 hours or less, the green light in the LED panel on the mower will come on. The yellow light will also be on. Both the green and yellow lights will be illuminated continuously until the charger is disconnected from both the wall outlet and the battery pack.
Recharging After Each Use of the Mower IMPORTANT! Always recharge the mower to a full charge immediately after each use, no matter how short a time it was used, even if the battery power indicator on the control panel is still green. (Green means only 30% or more of the battery power is remaining.) This is important in order to maintain maximum mower performance and extend maximum battery pack life.
