Models: 5680 / 5700
The following On- board Battery Charger information
is not included in your Operator or Parts List
manuals. Please keep this information with your
manuals for future reference.
CHARGING BATTERIES
ATTENTION: The on- board battery charger is preset
to charge wet/lead acid batteries (supplied with your
machine). If changing to a gel/sealed/ maintenance
free battery, the battery charger setting must be
changed to prevent possible battery damage. (See
ON- BOARD CHARGER SETTINGS).
The lifetime of the batteries depends on their proper
maintenance. To get the most life from the batteries;
SDo not charge the batteries more than once a day
and only after running the machine for a minimum
of 15 minutes.
SDo not leave the batteries partially discharged for
long period of time.
SOnly charge the batteries in a well-ventilated area
to prevent gas build up. Charge batteries in areas
with ambient temperatures 27_C(80_F) or less.
SAllow the charger to complete charging the batter-
ies before re-using the machine.
SMaintain the proper electrolyte levels of flooded
(wet) batteries by checking levels weekly.
WARNING: Fire Or Explosion Hazard. Bat-
teries Emit Hydrogen Gas. Keep Sparks And
Open Flame Away. Keep Battery Compartment
Open When Charging.
FOR SAFETY: When servicing batteries, wear
protective gloves and eye protection when han-
dling batteries and battery cables. Avoid contact
with battery acid.
USING THE ON- BOARD BATTERY CHARGER
1. Transport the machine to a well- ventilated area.
2. Park the machine on a flat, dry surface and turn
the key off.
3. Check the battery fluid level frequently to
prevent battery damage. The fluid should be at
the level shown (Figure 1). Add distilled water if
low. DO NOT OVERFILL. The fluid may expand
and overflow when charging. After charging,
distilled water can be added up to about 3 mm
(0.12 in) below the sight tubes.
NOTE: Make sure the battery caps are in place
while charging. There may be a sulfur smell after
charging batteries. This is normal.

4. Prop open the recovery tank for ventilation
before charging batteries (Figure 2).
5. Connect the charger’s AC power supply cord
into a properly grounded receptacle (Figure 2).
WARNING: Electrical Hazard. Batteries Emit
Hydrogen Gas. Keep Sparks And Open Flame
Away. Keep Battery Compartment Open When
Charging.
FIG. 2
WARNING: Fire Or Explosion Hazard. Do
Not Charge Batteries with Damaged Power
Supply Cord. Do Not Modify Plug.
If the charger supply cord is damaged or
broken, it must be replaced by the manufacturer
or its service agent or a similarly qualified
person in order to avoid a hazard.
6. The charger will display a sequence of codes
once the cord is connected (Figure 3).
Three- digits + the following code:
A = Charging current
U = Battery Voltage
h = Charging time
C = Charging ampere- hours [Ah]
E = Energy used [Kwh]
“GEL” or “Acd” = Current charger setting.
GEL=Sealed, Acd=WET (lead acid).
To change setting, see ON- BOARD
CHARGER SETTINGS.

ON- BOARD BATTERY CHARGER SETTINGS:
If changing from a wet/lead acid or gel/sealed/
maintenance free battery, the battery charger setting
must be changed to prevent possible battery
damage.
To verify the current setting of the charger, connect
the charger cord into an electrical receptacle. The
charger will display a sequence of codes. The
battery type code will either read “GEL” or “Acd”
(Figure 4).
GEL = Set for sealed/maintenance free batteries
Acd = Set for wet/lead acid batteries
FIG. 4
To change the setting, unplug the charger, peel up
the corner of the display label and set the switches
accordingly (Fig. 5). The charger cord must be
unplugged when resetting.
WET “Acd” BATTERY
SEALED “GEL” BATTERY
