18 DR
®
POWER GRADER
Charging the Battery is a simple process. Leave the Battery in your DR POWER GRADER when you charge
it.
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.
• Every time you finish using your DR POWER GRADER, recharge the Battery. The time it takes to
recharge the Battery depends on how drained it is when you start. Charging the Battery typically takes 6
to 8 hours if charged after each use. However, charging may take 24 to 48 hours if you allow the Battery
to run down before it is charged. 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 hundreds of 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 POWER GRADER.
• Once the Battery is charged, pull the plug from the wall outlet and then remove the Charger from your
Battery. However, you can leave your Battery plugged in and charging for an extended period.
• Store the Charger in its self-locking plastic shipping bag. Keep the charger in a dry location.
• 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, remove the Battery Cover, detach the cables and remove the dead Battery, next install the new
Battery and attach the cables, then replace the Battery Cover. Refer to the assembly instructions for
more details on page 13.
WHEN THE BATTERY GETS OLD AND NO LONGER ACCEPTS A CHARGE, REMOVE IT FROM YOUR
GRADER. NEVER LEAVE A DEAD BATTERY IN YOUR GRADER.
