HOW TO PREPARE THE MACHINE FOR OPERATION
How To Charge The Batteries
WARNING!
Charging the batteries in an area without adequate ventilation could result in an explosion. To prevent an explosion, charge the batteries only in an area with good ventilation.
WARNING!
Lead acid batteries generate gases which could explode. Keep sparks and flames away from batteries. NO SMOKING!
To charge the batteries, follow this procedure:
1.Make sure the key switch is in the “OFF” position.
2.Before charging the batteries, the battery compartment needs to be vented. To vent compartment, tip up the recovery tank until it locks in the open position (see figure #8). To close the tank, pull up on the arm and then slowly lower the tank to the closed
position. | Figure # 8 |
|
CAUTION!
Before raising tank, be sure tank is empty.
WARNING!
Do not operate or perform maintenance on the machine while the recovery tank is in the open position. The tank can be accidentally bumped and it may slam shut.
3.Put the charger on a flat surface. Make sure the vents on the sides are at least two inches away from walls and other objects. Make sure there are no objects near the vents on the bottom of the charger.
4.Disconnect the battery pack connector from the batteries.
5.Connect the DC connector on the charger to the battery pack connector. See figure #8A.
6.Connect the battery charger AC cord located at the rear of
the machine to a 10 amp (min) 230V properly grounded wall | Figure 8A | |
receptacle. | ||

7.Observe indicator light to ensure the charging process has started. Flashing light(s) indicates that the batteries are being charged. Steady on green light indicates the batteries are fully charged.
NOTE: Make sure you plug into a circuit that is not loaded by other equipment. Wall breakers may be tripped and no charge will occur.
WARNING!
Never charge a GEL battery with an unsuitable battery charger. Carefully follow the instructions given by the manufacturer of the batteries and battery charger.
NOTE: To prevent permanent damage to the batteries, avoid their complete discharge. Never leave the batteries completely discharged, even if the machine is not being used. When recharging the batteries, keep the recovery tank open. After every 20 recharging cycles, check the level of the electrolyte and if necessary top off with distilled water.
