TRIMMER/MOWER
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.
Battery Care (Electric-Start Models)
Proper care can extend the life of a battery. Follow these recommendations to ensure your Battery’s best performance and long
life:

Before charging the Battery, observe its external appearance and keep it clean and dry. Never charge or use a Battery that
shows cracks, changes shape, leaks, or otherwise obviously damaged.

Do not allow the Battery to run down completely before charging. Leaving the Battery discharged damages the Battery . If the
machine is not used, charge the Battery every 4 to 6 weeks. Operate the Engine for at least 45 minutes to maintain proper
Battery charge.

Store an unused Battery in a dry area that does not freeze.

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 the Engine when the Battery charge is low.

If the Battery begins to leak, avoid contact with the leaking acid. Place the damaged Battery in a plastic bag, then dispose of it
properly.
Charging the Battery
Operate the Trimmer 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 at no
more than 2 amps.

At 1 amp, the Battery may need charging for as long as 48 hours.

At 2 amps, the Battery may need charging 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 TRIMMER/MOWER, follow the steps listed below.
1. Detach the two (2) Battery wires going to the Battery on your DR TRIMMER/ MOWER.
2. Attach the black (-) Battery Charger wire to the Battery negative (-) terminal, and attach the red (+) Battery Charger wire to the
Battery positive (+) terminal.
3. Plug the Battery Charger into an outlet.
Disposing of the Battery Responsibly
The Battery is a sealed lead-acid Battery. Recycle or dispose of it in an environmentally sound way.

Do not dispose of a lead-acid Battery in a fire; the Battery may explode or leak.

Do not dispose of a lead-acid Battery in your regular, household trash. Law in most areas prohibits incinerating, disposing in a
landfill, or mixing a sealed lead-acid Battery with household trash.
If battery acid does contact your skin or eyes, flush with cool water for at least 15 minutes and call a physician. If you ingest acid,
call a physician immediately.
