Battery Care (For Electric-Starting Models Only)
Proper care can extend the life of a Battery. Follow these recommendations to ensure your Battery’s best performance and long
life:

Do not allow the Battery charge to get too low. If the machine is not used, charge the Battery every 4 – 6 weeks. Operate the
engine for at least 45 minutes to maintain proper Battery charge.

Store an unused Battery in a dry environment with temperatures b40°F (+5°C) and +95°F (+35°C). Make sure the
storage temperatures will never be outside of these limits. The lower the storage temperature is within the specified
temperature, the better as the battery will discharge more slowly at low temperatures.

Do not charge an already charged Battery. In theory, you cannot overcharge our Battery with a trickle charger; however, when a
Battery is fully charged and the charger is still on, it generates heat that could be harmful to the Battery. A fully charged Battery
will read 12V-13.2V with a voltmeter.

Do not continue to crank your Engine when the Battery charge is low.
Charging the Battery
Operate the Engine for at least 45 minutes to maintain proper Battery charge. If the Battery loses its charge, you will need to use a
trickle charger (like the DR Battery Charger) to recharge it. The Charger should have an output of 12 volts DC at no more than 2
amps.

At 1 amp the Battery may need to be charged for as long as 48 hours.

At 2 amps, the Battery may need to be charged for as long as 24 hours.
NOTE: Using the Recoil Starter and then running the Engine will not recharge a dead or significantly discharged Battery.
To connect a Battery Charger to your DR STUMP GRINDER, follow the steps listed below.
1.
Attach the Black (-) alligator clipped wire from the Charger Adapter to the Negative (-) terminal of the Battery, then attach the
Red (+) alligator clipped wire to the Positive (+) Battery terminal.
2.
Plug the Charger into a standard wall outlet.

Typically, the Battery takes between 6 and 8 hours to fully charge. Do not leave the charger on the battery longer than
24 hours for a 2 amp charger, or 48 hours for a 1 amp charger as you could potentially damage the battery..

You can charge the Battery many times. The Battery lasts longer if you charge it before it is fully drained. Keep it fully
charged and at room temperature when not using your DR STUMP GRINDER.

If the Battery does not hold its charge for very long under normal conditions or it simply won’t hold a charge, then
replace it. You can purchase replacement Batteries directly from us. To install your new Battery, follow the directions
on the next page.
When you are finished charging the battery, disconnect the charger from the outlet first, then disconnect the battery charger wires
from the battery. If you leave the battery charger wires connected to the battery, the battery will discharge itself back into the
charger.
