Note: The following page is for vehicles with battery’s containing separate electrolyte pack.
Preparing the battery:
· Place battery on level surface. Remove cap strip from top of
battery. (see gure 20)
. Wear eye protection and rubber gloves for this step. Once battery
strip is removed, locate electrolyte in bottle and place over the
six openings. Press rmly down on bottle allowing the battery to
pierce the six in-line openings in bottle. Let electrolyte drain into
battery until bottle is completely empty. (see gure 21)
· Discard empty electrolyte container in a waste area that is
inaccessible to children and animals.
· After lling let battery stand for at least 30 minutes before
charging. This allows the electrolyte to penetrate plates for
optimum performance and ensures longer battery life.
· After 30 minutes the battery is ready for its initial charge. Place
caps loosely over battery cell holes (see gure22)
How to Initially Charge the battery:
1. Connect the red positive (+) cable to the red positive (+) pole of the
battery.
(see gure 24)
2. Connect the black negative (-) cable to the black negative (-) pole
of the battery. (see gure 25)
Note: The red positive (+) cable has a larger diameter than the
black negative y cable.
3. Charging rate: Charge battery @ 0.7 Amps for
5 ~ 10 hours.
• After charging is complete, install securely all six battery caps
(see gure 26)
• Install battery into battery tray located under seat (see gure
27).
• Once battery is rmly seated in tray, attach red positive (+) wire to
positive (+) terminal on battery, then attach black negative (-) wire
