ADDITIONAL INSTRUCTIONS FOR BATTERY-POWERED UNITS
WARNING!
Working with or near lead acid batteries is dangerous. Batteries contain sulfuric acid and produce explosive gases. A
battery exposition could result in loss of eyesight or serious burns.
Do not smoke or allow a spark or flame near batteries. Charge batteries in locations which 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 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 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 the unit with the cord wrapped around itself can
cause the cord to overheat, melt, and cause a short-circuit or a fire.
Plug the charger into a standard 115V receptacle. If an extension cord must be used, keep it as short and as large as
possible. A small cord will decrease the output of the charger due to the voltage drop in the line. This will increase the
charging time. It can also cause the 115V cord to overheat.
When properly connected, the charge LED will indicate the status of charge current flowing to the battery, as follows:
Red only - the charger is providing full output to the battery.
Both red and green - the charger is "topping off" the battery.
Green only - the charger is providing a "float," or maintenance, charge.
Remember to unplug the charger before moving the equipment. Failure to do so could cause damage to cords, recep-
tacles and other equipment.
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.
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 leas 1/2 hour after the
charger has been turned off before checking the battery's voltage.
If the motor doesn't run, observe the green LED on the motor relay. If it is not lit, or if the LED goes out when the "UP"
control is pressed, the battery voltage should be checked with a voltmeter.
If the batteries aren't being charged by the charger, check the output charger fuse. If it is good, check the batter's state
of charge with a voltmeter.
