NOTE
Charge the batteries when the yellow or red warning light (81b or 81c) turns on, or at the end of every working
cycle.
CAUTION!
Keeping the batteries charged make their life last longer.
CAUTION!
When the batteries are discharged, charge them as soon as possible, as that condition makes their life
shorter. Check for battery charge at least once a week.
WARNING!
WET battery charging produces highly explosive hydrogen gas. Charge the batteries in well-ventilated areas
and away from bare flames. Do not smoke while charging the batteries.
Keep the tank assembly open while charging the batteries.
WARNING!
Pay careful attention when charging the batteries as there may be battery fluid leakages. The battery fluid is
corrosive. If it comes in contact with skin or eyes, rinse thoroughly with water and consult a physician.
