BATTERY RECHARGE

Recharge boom lift batteries after each 8-hour work shift or as needed. When boom lift is not in use, batteries should be recharged at least once per week. Under normal circumstances, battery recharge should take approximately 10-12 hours. However, a full recharge may take up to 24 hours, if the battery charge is extremely low.

The battery charger is located on the turntable behind the ground control panel.

WARNING

Recharge batteries in a well-ventilated area only. Do no charge batteries near fire, spark or other potential ignition sources. Batteries may emit highly explosive hydrogen gas while charging. Failure to properly ventilate the charge gases may result in serious injury or death. Always charge boom lift batteries away from flammable materials.

To recharge the boom lift batteries:

Move the boom lift to a well-ventilated area with direct access to 120 VAC electrical outlet. Keep the boom lift and batteries away from open flame or other potential ignition sources.

Attach a 12 AWG multi-strand, grounded extension cord with a maximum length of 50 feet (15 meters) to the receptacle located on the cargo plate in front of the turntable.

NOTE: Using an underrated or long power cord will reduce the output of the battery charger and may extend charge time.

Plug the extension cord into a grounded 120 VAC outlet. Verify that the green indicator LED is lit on the center of the battery charger faceplate (Figure 3-8).

The charger is equipped with an electronic timer that activates when the batteries reach a gassing threshold (2.3 volts per cell). The indicator LED will begin to flicker.

WARNING

Do not disconnect any output leads or connectors between the batteries and the charger when the charger is on. To stop a charge in progress, always unplug the extension cord from the AC power source.

After three hours, the electronic timer will cause the charger to shut off completely, indicated by the indicator LED going off. The batteries are now fully charged.

Unplug the extension cord from the 120 VAC outlet and the charger receptacle on the boom lift. Store the extension cord for next use.

CAUTION

Always unplug the battery charger power cord before moving the boom lift. Failure to disconnect power cord will cause damage to the equipment.

If LED does not become lit when power is applied, verify that charger is plugged into a live circuit.

Clean battery connectors if heavily corroded.

If LED does not go off, the charger has not reached a gassing threshold and is unable to actuate the timer. This indicates one or more shorted cells. Replace defective batteries as necessary.
