OPERATING THE MACHINE
GTTZ10EJ Operation Manual 7-7 © Mar. 2022
UNSAFE OPERATION HAZARD
• Make sure to read and follow the
manufacturer’s recommendations
on how to use and maintain the
battery.
• The battery contains sulfuric acid
and can generate explosive mix-
ture of hydrogen and oxygen.
Keep the battery far away from
sparks and fire (including ciga-
rette and smoke) to avoid
explosion.
• Do not charge the battery under
direct sunshine.
• Charge the battery on a well-venti-
lated site.
• Do not expose the battery on
charging to water or rain.
• Charge the battery at the proper
voltage as indicated on the decal.
• If the battery is topped by a cover
or other objects, remove them be-
fore charging to ensure the flam-
mable gas produced during
charging can be fully dispersed.
Do not close the cover until 30 mi-
nutes after the charging is com-
pleted. The charging site should
be well-ventilated and if charging
the battery indoor, a fan can be
used for better ventilation.
DAMAGED BATTERY HAZARD
• Only use the charger provided by
the manufacturer, and only con-
nect the charger to a grounded 3-
phase power outlet.
• Do not reverse the positive and
negative of the battery for
charging.
• Charge the battery as soon as
possible once the battery is
depleted.
• Do not deplete the battery more
than 80% of the standard capacity,
as frequent over-depletion of the
battery will shorten the battery
life.
• The battery must be charged fully,
as intermittent charging will bring
damage to the battery.
ELECTROCUTION HAZARD
• Contact with live circuit may
cause serious injury or death.
Make sure to wear goggles,
gloves and protective clothing.
• Remove all rings, watches and
other jewelry.
NOTICE
• The machine is delivered with a battery level less
than 80%, therefore it is recommended that the
battery be fully charged after receiving the
shipment.
• The charging current should not exceed the max
allowable charging current as specified on the
battery.
• The charging voltage should not exceed the max
allowable voltage as specified on the battery.
• The charging temperature range is -10℃~45℃. If
a charge heating system is available, the temper-
ature range is -20℃~45℃.
