Battery and Charger Instructions
Observe and Obey:
Do not use an external charger or booster battery.
Charge the battery in a well-ventilated area.
Use proper AC input voltage for charging as indicated on the charger.
Charge the battery as soon as receiving the machine or after long distance transportation
When the battery is stored for a long time, it needs to be charged regularly. Failure to charge in
time may permanently damage the battery.
Maintenance - Free Battery
Connect the battery charger to a grounded AC circuit.
The charger will indicate when the battery is fully charged.
Note:
In order to achieve an optimal service life, discharge of over 60% of the rated capacity should
be avoided. Discharge of over 80% of the rated capacity is a deep discharge and is not
permissible. These significantly reduce the service life of the battery. Only those discharge
state indicators that have been approved by the battery manufacturer may be used.
Discharged batteries must be charged immediately and must not remain in discharged state. This
also applies to batteries in a state of deep discharge. Otherwise, the service life of the battery will
be significantly reduced. The battery may freeze when in discharged state. Charge the battery
immediately when the machine displays “36” or “68” alarm code during work.
During the charging process, if temperatures are consistently higher than 122°F (50°C) or lower than
5°F (-15°C), stop charging to check whether the battery and charger are normal.
