Checking the 12-Volt Battery
Always check battery
energy before every lift.
While the lifter is powered up, a battery gauge on the LCD
screen displays the current energy level.

• If battery energy is in the red range, discontinue lifter
use and charge the battery (see “12-V

ECHARGE
” on page 34).
• If battery energy continues to decrease and you try to
attach the lifter to a load, the notification buzzer will
sound continuously and the LCD screen will display “Lockout (low 12V battery)”, along
with a diagnostic code (see “I

” on page 36). In this case, you
must charge the battery in order to continue using the lifter.
1..... Maximum buzzer volume is 95 dBA at 2' [60 cm]. If CE Standards apply, consult EN 7731 to make sure the notification buzzer is compliant.
2..... The “Vacuum Test” on page 30 provides a convenient opportunity to check this.
3..... If the lifter remains in “Power Save” mode for a long time, the pump will run periodically to test the battery.
4..... If the battery charger is connected to an AC power source, the reading on the battery gauge will not be accurate and “Replace 12V battery” may
appear on the LCD screen, because the system cannot accurately evaluate the battery.
