ECHARGE
CAUTION: Charge battery only while lifter’s power switch is in the “off” ( )
position.
Operating the lifter when the battery charger is connected to an AC power source could result in
permanent damage to the charger.
Only use a battery charger supplied by or approved by Wood's Powr-Grip; other chargers may
reduce battery life. Charge the battery as soon as possible after any extended use of the lifter,
or whenever the battery gauge indicates diminished energy (see B
ATTERY
T
EST
preceding).
Temperatures higher than 70° Fahrenheit [21° Celsius] require the battery to be charged more
frequently.
Identify the input voltage marked on the charger and plug it in to an appropriate power source.
15
The power source must be equipped with a ground fault circuit interrupter, in order to reduce the
risk of electrical shocks.
WARNING: Power source must be equipped with ground fault circuit interrupter.
Press the "MODE" button to select "NORMAL"
mode. After the mode has been selected, the
charger should begin to charge the battery
automatically. Lights #1-4 in the illustration
indicate the level of charging that has been
attained.
16 When the battery is fully charged, the
charger switches to a maintenance mode and
charging level light #4 (green) turns on. The
blue light on the battery gauge also turns on, to
indicate that the battery is fully charged. Be sure
to unplug the charger and check the battery
energy again before operating the lifter (see
B
ATTERY
T
EST
preceding).
When the lifter and its charger are used as
directed, the battery should take no more than 8
hours to charge completely.
17 However, following
long-term use, a battery gradually loses the
capacity to hold a charge. After reaching
charging level #3, the charger analyzes the
battery voltage, to determine whether or not the battery is holding a charge. If the battery does
not hold a charge adequately, the charger's red error light (!) turns on, indicating that the battery
needs to be replaced (see REPLACEMENT PARTS LIST).
15
Any external power supply must conform to all applicable local codes.
16
If none of the charging level lights turns on, the battery connection or the battery itself may be faulty. If the red error light
(!) turns on immediately, the battery leads may be reversed or the charger terminals may be short-circuited; once the problem
has been corrected, the charger should function normally. The red error light can indicate other problems, depending on the
mode selected and level of charging; if necessary, contact Wood's Powr-Grip for assistance.
17
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.
