6.2 Battery Maintenance
Never alter the AC cord or plug provided. If it will not fit outlet, have
proper outlet installed by a qualified electrician. Improper connection
can result in a risk of an electric shock.
PREPARING TO CHARGE A BATTERY
Always turn off E-stop and key switch before working with the batteries. Be sure the area around
the stacker and the battery is well ventilated while battery is being charged. The battery terminals,
connections and wiring connections should be clean and free of corrosion. When cleaning any of
these components wear a face shield or other suitable protective eye wear.
BATTERY CHARGING
Charging must be performed with the charger that is provided with or pre-wired into the machine.
During charging, the temperature in the battery must not exceed 120 F. Charging simultaneously
with truck operation is not recommended. Plug the charger into a 115 volt outlet. Charge until the
battery gauge indicator lights show fully charged (approximately 6-8 hours).
WARNINGS AND BATTERY INFORMATION
Avoid use of open flame near batteries. At temperatures around freezing point, battery capacity
is reduced by 30%. The battery terminals, connections and wiring should be clean and free
of corrosion. When cleaning any of these components, wear a face shield or other suitable
protective eye wear. Read, understand, and follow all battery and battery manufacturer’s specific
precautions while working with and/or charging batteries.
BATTERY MAINTENANCE
To measure the voltage, use a digital voltmeter (DC) on the battery poles. The truck must not
have been in use for the previous 30 minutes.
BATTERY CHARGER OPERATION
Disconnect the charger from the 115 volt wall outlet once the indicators read fully charged.
