2.7 BATTERY CHARGING & MAINTENANCE
(EL-DC MODELS ONLY)
EL-DC Models are equipped with 12 volt, 10 amp output
battery chargers (U.S.A. - 110/240V-AC/50/60Hz input).
The battery charger has a microprocessor controlled
automatic charge sensing circuit which can determine cell
voltage and regulate charger output as required. The
charger automatically terminates charging when a full bat-
tery charge is acheived.
Battery Maintenance and Safety Practices
(See Figure 2-2.)
ENSURE THAT BATTERY ACID DOES NOT COME INTO CONTACT
WITH SKIN OR CLOTHING. WEAR PROTECTIVE CLOTHING AND
EYEWEAR WHEN WORKING WITH BATTERIES. NEUTRALIZE ANY
BATTERY ACID SPILLS WITH BAKING SODA AND WATER.
BATTERY ACID RELEASES AN EXPLOSIVE GAS WHILE CHARG-
ING, ALLOW NO OPEN FLAMES, SPARKS OR LIGHTED TOBACCO
PRODUCTS IN THE AREA WHILE CHARGING BATTERIES.
CHARGE BATTERIES ONLY IN A WELL VENTILATED AREA.
ADD ONLY DISTILLED WATER TO BATTERIES. WHEN ADDING
DISTILLED WATER TO THE BATTERIES, A NON-METALLIC CON-
TAINER AND/OR FUNNEL MUST BE USED.
Check the electrolyte level of the batteries often, adding
only distilled water when required. When fully charged,
battery fluid level should be 1/8" below vent tubes. (See
Figure 2-2.).
• DO NOT fill to bottom of vent tubes.
• DO NOT allow fluid level to go below the top of the
plates when charging or operating.
Battery Charger Operation
(See Figure 2-3 & 2-4.)
Position machine in well ventilated area near an AC electri-
cal outlet and set the Ground Control-PLAT/OFF/GRND
key switch to the OFF position.
ALWAYS CHECK THE VOLTAGE SELECT SWITCH ON THE FACE
OF THE BATTERY CHARGER BEFORE OPERATION. IF NOT SET
TO THE PROPER AC POWER INPUT VOLTAGE DAMAGE WILL
OCCUR TO THE CHARGER.
1. Set the AC voltage switch on the face of the charger
for the local AC line voltage.
2. Remove the battery charger AC power cable stowed
inside the battery/charger carrier (beside charger).
Connect the battery charger AC power cable to a
properly grounded receptacle, use a suitable exten-
sion cord, if necessary.
3. When plugged in, the charger runs through a self-
diagnostic check. The LED’s on the front panel of
