REPLACING THE BATTERY
Risk of electrical shock or battery explosion,
which can cause serious injury or death.
Wear eye protection. Work in a well-
ventilated area. Do not smoke or allow a
spark or flame in the vicinity of the battery.
Avoid dropping metal tools on the battery.
If battery acid contacts eyes, flush with
water for 15 minutes and get prompt
medical attention. Review the safety
instructions on page 1.
REFER TO THE PHOTOS AT RIGHT
1. Unplug the charger and the blue AC pump
controller from the wall outlet.
2. Remove the cover of the battery box by
pushing in the tabs on the front and back,
then lifting up.
3. Fan the area around the top of the battery
with a piece of cardboard (or another non-
metallic material) to remove any hydrogen or
oxygen gas that may have been emitted from
the battery.
4. Remove the fluid sensor from the top of the
battery. Unscrew the wing nuts and remove
the battery cables.
5. Remove the old battery from the battery box
and place the new battery in the box. Fill the
battery following the instructions on page 4
or 5.
6. Clean any corrosion off of the ring
connectors on the ends of the battery wires.
Use a stiff brush or sandpaper. DO NOT
apply corrosion resisting sprays or pads to
the terminal rings or posts after you have
cleaned them, since this could prevent the
battery from charging properly.
7. Replace the battery cables, BLACK to the
NEGATIVE (-) post and RED to the POSITIVE
(+) post. Tighten the wing nuts.
8. (a) If your battery has six (6) caps on the top,
rinse and dry the cap with the extra hole from
the old battery to remove any residue.
Replace the battery cap in the cell that is 2nd
from the POSITIVE post with the cap from the
old battery. Insert the fluid sensor in the cap.
(b) If your battery has two caps, each
covering three (3) battery cells, simply insert
the fluid sensor in the top of the battery next
to the arrow.
9. Plug the charger and the blue AC pump
controller back into the wall outlet.
