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.
