Note: If this product has the 24V powered traction-drive option, consult that option’s information for more
specific details regarding the batteries and battery charger.
Warning!
!
Working with or near lead acid batteries is dangerous. Batteries contain sulfuric acid and produce explosive
gases. A battery explosion could result in loss of eyesight or serious burns.
!
Do not smoke or allow a spark or flame near batteries. Charge batteries in locations that are clean, dry, and
well ventilated. Do not lay tools or anything metallic on top of any battery. All repairs to a battery must be
made by experienced and qualified personnel.
!
When working with batteries, remove personal items such as rings, bracelets, necklaces, and watches.
Batteries can produce enough energy to weld jewelry to metal, causing a severe burn.
!
Always have fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
!
Operating the battery with a low battery voltage can cause premature motor contact failure.
!
Do not expose the lift or the charger to rain or adverse conditions.
!
Replace defective cords or wires immediately.
!
Check the battery’s water level frequently.
Battery Charger Operating Instructions
Never operate the charger with either of the cables coiled. Operating a battery charger with the cord either
coiled or wrapped around itself could cause the cord to overheat, melt, and cause a short-circuit or a fire.
Connection: the ribbed wire of the charger’s output cord must be connected to the battery’s negative (-)
terminal. The non-ribbed wire (with words printed on it) must be connected to the battery’s positive (+)
terminal.
When properly connected, the charger will indicate the status of its output:
Flashing green LED – the charger is not seeing a good connection to the battery.
Solid yellow LED – the charger is providing charging current to the battery.
Solid green LED – the charger is maintaining a fully charged battery.
Plug the charger into a standard 115V receptacle. If an extension cord must be used, keep it as short as
possible.
Caution: Remember to unplug the charger before moving the equipment. Failure to do so could cause
damage to cords, receptacles, and other equipment.
The battery charger can be left connected to the battery indefinitely without risk of harming the battery.
Troubleshooting:
If the unit does not operate, check all of the wiring connections to make sure they’re both mechanically and
electrically sound – specifically at the battery, the motor, and at any location a wire is connected to the chassis.
Also, make sure the quick-connect plug on the end of the pendant control cord is plugged in correctly (if
applicable).
A fully charged lead acid battery in good condition at room temperature should read 12.65 volts. At 11.9
volts it is considered to be fully discharged and in need of charging. When checking battery voltage, wait at
least 1/2 hour after the charger has been turned off before checking the battery’s voltage.
If the batteries don’t seem to be taking a charge, check the charger’s 115V supply circuit and the
charger’s output with a voltmeter. If all check okay, confirm the battery’s state of charge using a hydrometer or
a voltmeter.
