BATTERY CHARGING INSTRUCTIONS

Charge the batteries at the end of each day or when the battery condition meter indicates low battery voltage. The batteries need to be charged when the needle stays in the “red” zone while the machine is being operated. When charging batteries, only use the quick disconnect provided. Use the quick disconnect to insure correct polarity.

Check the liquid level in the batteries a least once a week and add water when low. Use only distilled water. Fill the batteries after charging the batteries to prevent electrolyte from spilling over on to the tops of the batteries during the charging process.

WARNING

The use of an extension cord with the charger should be avoided. Risk of fire and electrical shock is possible if the wrong type or size extension cord is used. If an extension cord must be used, only use a three conductor number 12 AWG cord with ground, properly wired, in good electrical condition and keep it as short as possible. Locate all cords so that they cannot be stepped on, tripped over, or otherwise subjected to damage or stress.

WARNING

Verify that the AC power source to which the charger is to be connected is capable of supplying the current

specified on the charger nameplate.

WARNING

Keep all charger ventilation holes at least 2 inches away from walls or other objects. Do not allow vent holes to

become obstructed.

WARNING

Do not operate charger that has been damaged or shows physical signs of damage. Have charger serviced by a

qualified professional repair person.

WARNING

Lead acid batteries generate gases which can cause an explosion. Keep sparks and flames away from batteries.

NO SMOKING. Charge batteries only in area with good ventilation and always leave the top cover open while charging batteries. Do not disconnect the charger from the batteries before disconnecting the AC power cord. Disconnecting the battery cable with the charger plugged in could cause an explosion.
