ECHARGE
Charge the battery whenever the battery gauge indicates diminished energy (see B
ATTERY
T
EST
preceding). Caution: Make sure the lifter's power switch is in the OFF ( ) position.
Identify the input voltage marked on the battery charger, and plug it in to an appropriate power
source. 24 Use a ground fault circuit interrupter to reduce the risk of electrical shocks.
Make sure power source is equipped with ground fault circuit interrupter.
The power lamp (Ф) turns on, to indicate
that the charger is functioning. To
determine charging status, consult the six-
stage display on the charger. The battery
is ready for use at stage 3 and fully
charged at stage 5.
Normally, the battery should take no more
than 8 hours to charge completely. 25 If
not, check for the following conditions and
correct any deficiencies as directed:
• Power lamp (Ф) flashes: Charger is not connected to battery; reconnect charger (see
ASSEMBLY).
• Error lamp (!) turns on: Battery leads connected to the wrong poles; reverse battery leads.
• Error lamp (!) turns on and charging stops at stage 1 or stage 4: Battery is no longer
functioning; replace battery (see REPLACEMENT PARTS LIST).
Be sure to unplug the charger and test the battery energy again before operating the lifter (see
B
ATTERY
T
EST
preceding).

Any external power supply must conform to all applicable local codes. Caution: Do not operate the lifter while the
charger is connected to an AC power source, since this could result in permanent damage to the charger.
25
The charger is designed to automatically sense the energy level of the battery and reduce the charging rate when the battery
is fully charged. Accordingly, the charger does not need to be unplugged until the lifter is going to be used again.
