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 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 your Engine when the Battery charge is low.
Charging the Battery
Operate the vacuum 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 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 LEAF and LAWN VACUUM, follow the steps listed below.
1. Attach the Black (-) alligator clipped wire from the Charger Adapter to the (-) terminal of the Battery, then
attach the Red (+) alligator clipped wire to the (+) Battery terminal.
2. Plug the Charger into a standard wall outlet.
•
Typically, the Battery takes between 6 and 8 hours to fully charge. The Battery does not have a
“memory”; so don’t worry about overcharging the Battery or charging it too often.
•
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 LEAF and LAWN
VACUUM.
•
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, detach the cables, remove the Battery Clamp, and remove the dead Battery. Next,
install the new Battery, replace the Battery Clamp, and attach the cables. Refer to the assembly
instructions for more details on page 25.
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.
