Maintenance, Recharging and Replacement of the Accumulator
5.1 Safety procedures for accumulator operation
The truck must be parked in a safe location before any operation on the accumulator.
5.1.1 Maintenance Technician
Only a qualified technician can perform operations on the accumulator such as recharging,
maintenance and replacing. Before operation, carefully read instruction manuals including operation
manual, replenishment preparation and recharging requirements.
5.1.2 Fire Prevention Measures
Never smoke or use open fire when performing operations on the accumulator. The
accumulator should be at least two meters away from flammable material when storing or recharging.
The area for accumulator operation should be well ventilated and equipped with fire fighting devices.
5.1.3 Maintenance of the Accumulator
1) Keep the nuts of the accumulator clean and dry. Exposed cable ends and terminal posts should
be covered with a skid-proof insulating cover.
2) The wires should be well-connected. Check the screw bolts on each pole, if loose, tighten the
nuts.
3) Over recharging and over discharging should be avoided, and fast charging and insufficient
recharging are also not allowed. Otherwise the life span of the accumulator may be affected.
4) Do not put conductive objects (including metal tools) on the accumulator, or short circuit or even
explosion may be caused.
5) 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.
6) 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.
7) The site for recharging should be well ventilated. It is prohibited to smoke or use open fire,
avoiding the risk of explosion.
8) The electrolytic solution of the accumulator is poisonous and corrosive, so it is prohibited to put
the accumulator upside down under any circumstances.
5.1.4 Disposal of worn-out accumulators
Worn-out accumulators should be recycled according to local regulations, and stored in
specified zone or cast-off treatment zone. This work should be carried out by qualified specialized
companies.
