4.6 BATTERIES AND CHARGING
BATTERIES MUST BE RECHARGED IN A WELL-VENTILATED AREA FREE OF
FLAME, SPARKS OR OTHER HAZARDS THAT MAY CAUSE EXPLOSION.
HIGHLY EXPLOSIVE HYDROGEN GAS IS PRODUCED DURING THE CHARGING
PROCESS.
1) Recharge batteries at the end of every working day or shift.
(Note: To recharge batteries fully from flat takes approx. 12 Hours, this consists of 8 hours bulk
charging plus 4 hours equalisation).
2) Plug charger into suitable power supply, either 240 volts or 110 volts AC (see Charging
Limitations). (Note: If using 240V, use of a suitably rated Earth Leakage Circuit Breaker (ELCB)
or Residual Current Device (RCD) at the point of supply is highly recommended).
3) Take note of the indicators provided:
Red Light - Batteries are charging.
Pulsing Green light - the charge is equalising.
Constant Green light and pulsing Red light - the batteries are fully charged.
UNDER NO CIRCUMSTANCES SHOULD BATTERIES BE LEFT ON CHARGE FOR
PERIODS IN EXCESS OF 24 HOURS
4) DISCONNECT FROM POWER SUPPLY ONCE BATTERIES ARE FULLY CHARGED. The
machine can now be left unattended, however, in the event of the machine being left unused for
extensive periods then a 4 to 6 hour ‘top-up’ charge every 4 weeks is recommended. A ‘top-
up’ charge the day before use ensures a full day of operation from the machine.
UNDER NO CIRCUMSTANCES SHOULD A MACHINE BE LEFT FULLY
DISCHARGED AS SEVERE BATTERY DAMAGE CAN OCCUR IN A RELATIVELY
SHORT TIME.
5) To avoid damage to charger disconnect from mains supply before using machine.
Note:
1) If the charger is reconnected to the power supply shortly after it has gone through its full
charging cycle the Red LED may come on although the batteries may be fully charged. The
charger would then go through its complete cycle again at an accelerated rate, depending on the
time difference between connection, reconnection and level of battery charge.
