3.4 BATTERY MAINTENANCE
Electrical energy for the motor is supplied by four 6 volt batteries wired in series for 24 volts DC.
Proper care and maintenance of the batteries and motor will ensure maximum performance from
the work platform.
NOTE: If system voltage drops below 17 volts (on a 24 volt system), the charger will not recharge the
batteries. If this extreme voltage drop occurs, disconnect and recharge each battery separately,
using a 6 volt charger to bring the voltage in each up to at least 4 1/2 volts.
BATTERY INSPECTION AND CLEANING
Check the battery fluid level daily, especially if the work platform is being used in a warm, dry cli-
mate. If required, add distilled water ONLY. Use of tap water will shorten battery life.
The battery should be inspected regularly for signs of cracks in the case, electrolyte leakage,
and corrosion of the terminals. Inspect cables for worn spots or breaks in the insulation and for
broken cable terminals.
Clean the battery when it shows signs of corrosion at the terminals or when electrolyte has over-
flowed during charging. Use a baking soda solution to clean the batteries, taking care not to get
the solution inside the cells. Rinse thoroughly with clean water. Clean the battery and cable con-
tact surfaces to a bright metal finish whenever a cable is removed.
BATTERY CHARGING
Figure 3-1: Battery Charger
Charge the batteries at the end of each
work shift, or sooner if the batteries
have been discharged.
When night temperatures fall below
18°C (65°F), batteries charged in
unheated areas should be placed on
charge as soon as possible after use.
Under such conditions, a 4 hour
equalize charge once a week in the
early afternoon will improve the state
of charge and battery life.
WARNING
!
!
Hazard of explosive gas mixture. Keep sparks, flame, and smoking material
away from battery.
Always wear safety glasses when working with batteries.
Battery fluid is highly corrosive. Thoroughly rinse away any spilled fluid with
clean water.
CAUTION
!
!
If battery water level is not maintained, batteries will not fully charge,
creating a low discharge rate which will damage the motor/pump unit and
void the warranty.
