SYMPTOM POSSIBLE CAUSE
The Motor fails to start
with the Safety Key and
Battery installed and the
Wire Trigger 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 not, replace with a fully charged
Battery or recharge the Battery.
Make sure you follow the correct starting sequence of pushing the Bail Bar Engage Button in first
and then pulling the Bail Bar 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 Mower runs slow.
The Battery Pack was probably not at full charge prior to cutting. Charge the Battery Pack, if
necessary.
Check the Blade for sharpness or damage. Sharpen or replace as needed.
The Grass is too tall for the mower. Set the cut height higher if the grass is of reasonable height
for the Battery Mower or mow first with a DR Brush Mower.
The Motor doesn’t have
much power when you
use the Mower for the
first time.
You will initially need to charge the Battery Pack before use. The Battery Pack may need to be
cycled through a Charge and Discharge 2-3 times to achieve full charge potential.
The Battery loses its
charge quickly.
The Battery Pack was probably not at full charge prior to trimming. Charge the Battery Pack, if
necessary.
The Battery Pack may be getting old. After some time, you will need to replace the Battery Pack.
The Mower stops while
mowing (for reasons
other than releasing the
Bale Bar).
The Battery Power is depleted. Recharge the Battery or install a fully charged Battery.
The Trimmer Head may be clogged with debris. Remove the Safety Key and Battery, tilt the
Trimmer back onto the Handlebar and clean as needed.
If the Trimmer bogs down or stalls in heavy grass, raise the Trimmer Cord height, walk more
slowly, or cut a narrower swath. If the grass is wet, let it dry before mowing.
Excessive vibration or
noise
The Cords may not be the same length or one is missing. Remove the Safety Key and the
Battery; tilt the Trimmer back onto the Handlebar and adjust or replace Cords as needed.
The Mow-Ball
®
or a component in the Drive Belt system may be loose. Remove the Safety Key
and Battery, tilt the Trimmer back onto the Handlebar and adjust or replace parts as needed.
Before performing any maintenance procedure or inspection, release the bail bar to stop the motor and remove the battery and
safety key to prevent accidental starting.
