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:
Pulsing
Green 50% LED
- Batteries are charging and between 0 & 50% capacity.
Constant Green 50% LED and pulsing
Green 75% LED
- Batteries are charging and between
50% & 75% capacity.
Constant Green 50% & 75% LED’s, plus pulsing Green 100% LED
- Batteries are charging
and between 75% & 100% capacity.
Constant Green 50%, 75% % 100% LED’s
– batteries are fully charged.
Red Gel lamp
– Only applicable to sealed type batteries.
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 charger will show a Green 50% lamp, immediately followed by the Green
75% lamp. The charger would then repeat its complete cycle again at an accelerated rate,
depending on the time difference between connection, reconnection and level of battery charge.
