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.
18
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.
Using a Large Charger
If the lifter is equipped with a large (7 amp)
battery charger, press the "MODE" button to
select "NORMAL" mode.
19 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.
20 When the battery is fully
charged, the charger switches to a maintenance
mode and charging level light #4 (green) turns
on. When you perform a B
ATTERY
T
EST
, 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
18
Any external power supply must conform to all applicable local codes.
19
CAUTION
: Always use "NORMAL" mode to charge the battery, unless directed to do otherwise. "SUPPLY" mode circumvents
some safety features, which could result in property damage and possible injury.
20
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.
