Safety
Precautions for Maintenance
● The battery can generate inflammable
hydrogen to probably cause explosion.
Keep away from fire sources including
open fire, spark, and ignited cigarette.
● Use a flashlight to check the electrolyte
level.
● Ensure to turn off the starter switch and
stop the engine before checking or
handling battery.
● Never touch the electrodes by any metal
tool or object, in order to prevent short-
circuit.
● The loose electrodes can generate electric
spark. Ensure to tighten any loose
electrode.
● Ensure that the battery cover is securely
covered.
● If the battery is frozen, do not charge the
battery or attempt the jumper start of
engine, otherwise it will probably cause
explosion. Before use, heat the frozen
battery to 15°C.
● Do not use the battery when the electrolyte
level is below the lower limit. Otherwise it
will speed up the internal aging and
shorten the life of battery. In addition, it
can lead to burst (explosion).
● Do not fill the distilled water till the level
is above the upper limit. Otherwise the
electrolyte will leak out. The contact with
such electrolyte can harm your skin or
corrode the machine parts.
● Clean the surrounding area of electrolyte
level marking by a wet cloth and check the
level. Do not clean by a dry cloth,
otherwise it can cause electrostatic
accumulation and combustion or explosion.
Periodically Replaced Critical Safety Parts
● To guarantee the safe operation of machine
for a longer time, add the oil and fulfill the
checking and maintenance periodically. To
promote the safety, periodically replace the
critical safety parts, including hoses and
seat belts. To understand more details,
please refer to the section "Periodically
Replaced Critical Safety Parts".
● "Periodically replaced critical safety parts"
refers to the parts aged, worn, and
functionally deteriorated after repeated use.
The performances of such parts will
change along with time. These
characteristics of such parts can cause
serious mechanical damages or personal
harms and the remaining lives of such
parts can't be judged by merely
appearance checking or operation
hand-feel.
