充电步骤：

1.拔开蓄电池电缆和叉车电缆的接插头连接。

2.打开蓄电池上的盖板，测量电解液的密度，如果电解液的密度小于1.13公斤，说明蓄电池已过度放电(放电深度超过了80%，应提醒使用者注意，避免多次发生而缩短电池的寿命。

3.测量电解液的温度，如果大于45C，则应等蓄电池冷却后再继续如下步骤。

4.接上蓄电池与充电机电缆之间的插头。如配备 Trak air(空气扰动系统)请确认空气管路已接上。如配备自动加水系统，接上水管。

5.打开充电机的充电开关，开始充电。

6.充电结束后，先关充电机电源，然后拨开蓄电池和充电机的电缆插头连接。

7.如蓄电池配备半自动水液补充系统，接上水管插头，结束后拔离插头。

8.如没有蓄电池自动或半自动水液补充系统，则要检查电解液的充电后的液面高度，如液位低于允许高度(低于加水塞)，则应补充符合标准的蒸馏水或去离子水(0水塞位向上1-2厘米)，但不可加人任何酸液。

9.加水少须在充电后进行，充电前加水，可能导致充电时酸液溢出。

10.接上电池和电瓶车的电缆插头，叉车可投人使用。

Charging steps:

1. Disconnect the plug connection of the battery cable and the forklift cable.

2. Open the cover on the battery and measure the density of the electrolyte. If the density of the electrolyte is less than 1.13 kg, the battery has been over-discharged (the depth of discharge exceeds 80%. Users should be reminded to avoid multiple occurrences and shorten the battery. Life.

3. Measure the temperature of the electrolyte, if it is greater than 45C, wait for the battery to cool down before proceeding to the following steps.

4. Connect the plug between the battery and the charger cable. If equipped with Trak air (air disturbance system), please make sure that the air pipe is connected. If equipped with an automatic water filling system, connect the water pipe.

5. Turn on the charging switch of the charger to start charging.

6. After charging, turn off the power of the charger first, and then unplug the cable plug of the battery and charger.

7. If the battery is equipped with a semi-automatic water replenishment system, connect the water pipe plug and unplug the plug when finished.

8. If there is no automatic or semi-automatic water replenishment system for the battery, check the level of the electrolyte after charging. If the level is lower than the allowable height (lower than the water plug), the standard distilled water or deionized water should be added Water (1-2 cm from the lowest position of the 0 water plug), but no acid can be added.

9. Less water must be added after charging. Adding water before charging may cause acid overflow during charging.

10. Finally, connect the battery and the cable plug of the battery truck, the forklift can be put into use.
