3-5 BATTERY RECHARGE (DC MODEL ONLY)
The DC 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 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
explosive 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, flame or
other ignition sources.
2. Turn the BATTERY ON/OFF switch to the OFF position.
3. Plug a short, heavy-duty power cord into the battery charger receptacle on the
front of the battery compartment. The recommended power cord should be an
12 AWG multi-strand, grounded cord no longer than 20 feet (6 meters).
NOTE: Using an underrated or long power cord will reduce the output of the
battery charger, resulting in longer charge time.
