5) Do not put conductive objects including metal tools on the accumulator, or
short circuit or even explosion may be caused.
6) Never spill any hazardous liquid or solid material on surfaces of the
accumulator. When using a densimeter or a thermometer, make sure the surface
is clean and clear.
7) Recharge the discharged accumulator in time. Delayed recharging may
damage the accumulator. Do not delay recharging more than 24 hours.
Recharging of the accumulator may not work outdoors in cold weather. In this
case, move it indoors to perform recharging.
8) If the accumulator will not be in use for a long time, it should be recharged and
discharged once every month and it should be fully recharged every time.
9) During recharging or using, the liquid level of electrolyte lowers because of
water evaporation, so pure water should be added. It is not allowed to add
electrolyte with a specific weight of 1.280.
10) If individual cell fails, identify the cause and repair the cell immediately.
Replace the cell when it cannot be repaired.
11) The site for recharging should be well ventilated. It is prohibited to smoke or
use open fire, avoiding the risk of hydrogen explosion.
12) The electrolyte in accumulator is toxic and corrosive. For this reason, always
wear working suit and protection glasses to protect your body from contacting
the electrolyte in accumulator.
13) If your clothes, skin or eyes are spilled with acid liquid in accumulator, flush
with large amount of clean water. For skin and eyes, flush with large amount of
clean water and also seek doctor’s treatment immediately. Acid spillage must be
neutralized and treated immediately.
14) The weight and dimensions of the accumulator have remarkable effect on
stability of the stacker. Therefore do not modify the type of accumulator without
approval from the manufacturer.
15) Never discharge in large current, for example, performs travelling and lifting
simultaneously.
4.4.4 Disposition of worn-out accumulators
Worn-out accumulators should be recycled according to local regulations, and
stored in specified zone or cast-off treatment zone. These works should be done
by qualified specialized companies.
