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 fl ames 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 fi gure #8). To close the tank,
pull up on the arm and then slowly lower the tank to the closed
position.
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 fl at 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 fi gure #8A.
6. Connect the battery charger AC cord located at the rear of
the machine to a 10 amp (min) 230V properly grounded wall
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.
