NEUTON EM 4.1 Cordless Electric Mower Safety & Operating Instructions 15
Controls and Features
Make certain that you are familiar with the controls, parts, and operation of your NEUTON Mower
before using it.

Key Slot

The key slot is for both the external ba ttery charger and the safety key. T his design serves as a saf ety
measure: you can never connect both the e xternal battery charger and insert the safety k ey at the
same time. In other words, you can either operate your mower or charge its ba ttery;you cannot do
both at the same time.

Safety Key

Insert the safety key t o run the motor (Figur e 11). The
safety k ey can be inserted either way — it has no front
or back.
The sa fety key has a built-in circuit br eaker to protect the
motor. When the built-in circuit br eaker is tripped,
the white button on top of the safety k ey will pop up.
Before attempting to restart the mower,push the w hite
button all the way down until it locks into place. (There is
no replacement fuse inside the safety key.)

Start Button

The start b utton starts the motor (but only when the
control levers are depressed).

Control Levers

The control levers ar e a safety feature. When the levers are depressed, the motor continues to run
and the blade spins. When the le vers are released, the motor shuts off and the blade stops spinning
within three seconds.

Indicator Light

The status indicator light on the upper handb lebar
assembly (Figur e 12) illumina tes when a char ged
battery is installed and the safety key inserted. T he
light is green.
Note: A green indica tor light does not guarantee
that the battery is fully charged, only that it has
some charge, tha t the electrical system is ready, and
that the mower can be started.
WARNING! If the green light goes out, do not operate the mower again until the
battery is fully charged; otherwise the battery’s charging capacity might be
decreased.
