3-5 BATTERY RECHARGE (DC MODEL ONLY)
The DC model boom lift batteries should be recharged after each 8-hour work shift or
more often if needed. When the boom lift is not in use, the batteries should be recharged
at least once per week.
The normal charge time is 10 to 12 hours. If the battery charge is extremely low, a full
recharge may take up to 24 hours.
Recharge the DC model boom lift batteries as follows:
WARNING
Recharge the batteries in a well ventilated area only. Do not charge batteries near
fire, flame, or other ignition sources. Batteries being charged may emit highly ex-
plosive hydrogen gas. Failure to properly ventilate the charge gases may result in
serious injury or death.
1. Move the boom lift to a well ventilated area with direct access to a grounded
120 VAC electrical outlet. Make sure the recharge area is not near fire, flames
or other ignition sources.
2. Plug a short, heavy-duty power cord into the battery charger receptacle on the
electrical cord connected to the charger. The recommended power cord should
be an 12 AWG multi-strand, grounded cord no longer than 50 feet (16 meters).
NOTE: Using an underrated or long power cord will reduce the output of the
battery charger, resulting in longer charge time.
3. Plug the power cord into a grounded 120 VAC receptacle. Verify that the red
ON-CHARGING indicator LED lights up on the battery charger.
4. To determine the charge rate at any time during the charge cycle, observe the
DC ammeter (Figure 3-9). The ammeter needle moves to the right at the start of
the charge cycle. As the battery charge rises, the needle moves farther left.
