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.
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 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.
