Battery Care
(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 continue to crank the engine with a low battery.
•
Try to keep the battery at full charge to maximize its life. If the machine is not used, the
battery should be charged every three months. See below for charging information.
•
Store an unused battery in a dry area that does not freeze.
•
Do not charge an already charged battery. In theory, our battery cannot be overcharged 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.
Automobile batteries last for years because they are recharged every time you drive your car—
usually on a daily basis. An Electric-Starting DR
® TRIMMER/MOWER™ will recharge its
battery while you operate it continuously for about 45 minutes or more. However, if you run
your DR
® infrequently, less than 45 minutes with each use or let it sit during the off-season
without recharging, the battery life will be dramatically shortened. If the battery loses its charge,
use the DR
® Battery Charger (available from Country Home Products ® ) or other trickle charger,
to recharge it. The charger should have an output of 12 Volts at 1-2 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
1. Detach the two battery wires going to the wiring harness on your DR ® TRIMMER/
MOWER ™ .
2. Next, attach the black (-) battery charger wire to the black (-) wire. Then attach the red (+)
battery charger wire to the red (+) wire.
3. Plug the battery charger into an outlet.
4. When the battery is charged, disconnect the charger from the battery before unplugging it
from the outlet.
Battery Troubleshooting
Symptoms of a battery needing a charge:
• The engine won't start with the key but will start with the recoil starter.
• A whirring noise coming from the starter.
• A grinding noise coming from the starter.
• No noise at all.
