22 NEUTON EM 4.1 Cordless Electric Mower Safety & Operating Instructions
Inserting the Battery
1. Correctly orient the battery. Face the indicator
light and the arrow on the sticker towards the
metal bar. The indentations on the bottom of the
battery must line up with the metal tabs in the
bottom of the housing.
2. After confirming the correct orientation of the
battery, insert the battery into the battery opening
(Figure 21). The battery snaps into place.
Important: If the battery is not oriented correctly, it
will not fully depress into the opening. If this happens,
remove the battery, recheck the orientation, and try again.
Caring for the Battery
You can lengthen the life of your battery and reduce your average annual battery cost by following
some simple guidelines. These guidelines explain how and when you should charge the battery, and
how you should do it.
■ Always charge the mower indoors in a garage or other covered area where it will be dry and
protected from the weather.
■ Only charge the mower when the temperature is at least 32°F (0°C) — above freezing — but
not more than 104°F (40°C). Charging in lower or higher temperatures can be harmful to the
battery.
■ Always keep the mower away from water, heat sources (stoves, radiators, open flames, etc.), and
hazardous chemicals.
■ Always use the NEUTON™ Mower EM 4.1 Charger to charge your battery; never attempt to
use any other charger. This charger is specifically designed to optimize the performance of your
battery.
■ Never use the charger with any other product. Never operate the charger if it is damaged. If a
cord or the charger unit has been damaged, replace the charger or have it repaired.
■ Do not worry about leaving the battery charging for longer than 12 hours — the mower cannot
be overcharged and will not be damaged after 12 hours. Still, try not to leave the battery always
charging.
■ When storing the battery after removing it from the mower, follow the storage guidelines in
“Chapter 7: Maintaining and Storing Your NEUTON Mower.”
■ For long term storage, please refer to “Recharging to a Full Charge for Off-Season Storage” on
page 25.
