The Motor fails to start
with the Safety Key and
Battery installed, and
the Control Bar
depressed.
⇒
Check to make sure that you properly inserted the Safety Key.
⇒
Check that you installed the Battery correctly and that the Battery is fully charged. All four LEDs
of the Battery Test Button should light up when pressed if it is fully charged. If not, replace with
a fully charged Battery or recharge the Battery.
⇒
Make sure you follow the correct starting sequence of pushing the Safety Lock Button in first and
then pulling the Wire Trigger to the Handlebar.
⇒
Possibly the Blade is obstructed. Remove the Safety Key and Battery, turn the Mower over, and
check the Blade to make sure the Blade spins freely and is unobstructed.
The Battery Pack will
not charge.

Check to see if the Battery Pack is all the way into the Charger. Insert the Battery Pack until the
Green LED Light illuminates.
⇒
The Charger Power Cord is not plugged into a working outlet. Check the outlet with a lamp or
other appliance.
⇒
Check to see if the outlet that you are using for the Charger Power Supply is controlled from a
wall switch.

The surrounding air temperature is too hot or too cold. Move Charger and Battery Pack to a
location where the surrounding air temperature is between 50ºF (10ºC) and +100ºF (+37.8ºC).

The Battery Pack was probably not at full charge prior to cutting. Charge the Battery Pack, if
necessary.

that the Blade is securely attached.
