Servicing Batteries:
WARNING
NEVER SMOKE or use other COMBUSTIBLES near batteries while servicing batteries or other components.
ALWAYS remember presence of hydrogen fumes could lead to EXPLOSION.
ALWAYS provide plenty of ventilation.
CAUTION
NEVER add acid to batteries.
USE DISTILLED WATER ONLY.
DO NOT over-fill.
Keep fluid filled to proper level.
Add water to batteries ONLY AFTER CHARGING, unless water level is below plate upper edges.
Fluid expands from charging as it gets warm, and may seep out of batteries.
When water is then added, solution is weakened and a loss of ampere-hour capacity results.
1. Battery care has a direct impact regarding efficient operation of THE MAXI-LIFT
®
.
2. Check battery water levels and wiring daily.
3. Charge the batteries fully after prolonged use of THE MAXI-LIFT
®
.
4. If batteries are allowed to remain discharged, lead plates will harden and become sulfated. In this condition, batteries fail to deliver rated capacity or be fully charged.
5. THE MAXI-LIFT
®
is equipped with an automatic, self-monitoring battery charger.
6. To charge batteries, plug extension cord into frame power inlet and other cord end plug into a 120 Volt AC outlet (240 on some models).
7. Check each battery water level and turn ON/OFF switch to OFF position. Charger will now operate.
8. When charging, two charger LEDs indicate current charging stage.
9. Most charging occurs during first stage. RED (upper) LED will be illuminated.
10. Both LEDs are on during second stage. Last charge amount is applied without overheating batteries.
11. When batteries are fully charged, only GREEN LED will be on.
12. Charger will continue to monitor batteries’ charge, and top it off when needed without damaging battery or boiling off electrolyte solution.
13. Batteries can be charged indefinitely without overcharging.
14. Check fluid level and refill every 15 HOURS of use and when recharging.
15. Wash any battery corrosion or dirt with solution of 5 teaspoons baking soda in 1 quart of water.
16. Coat terminals with petroleum jelly or equivalent coating.
17. Remove battery caps and check fluid level.
18. If needed, fill as follows: Before charging, fluid must be above plates. After charging, fill to split ring.
