EPLACEMENT
The Vacuum Loss Warning Buzzer is designed so its battery can be tested while the lifter is not
running or attached to a load: Press the battery test button and observe the color of the battery
indicator light (note that the buzzer sounds, also, if the button is held more than a few seconds).
A
green light indicates that the battery is in good condition, whereas a red light indicates that the
battery does not have sufficient energy to power the Warning Buzzer. If a red light is showing,
replace the battery, as follows:
1) Insert a coin or screwdriver in the slot at the bottom of the battery holder and press inward.
2) While continuing to press in, press up on the battery holder. The battery tray should slide out
easily.
3) Remove the battery from the tray.
4) Install a new 9-volt battery, matching the polarity marked on the battery with the polarity
marked on the tray.
5) Slide the battery tray into the battery holder until the tray snaps into place.
6) Retest the Warning Buzzer.
