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. Place the machine on a flat-level surface with
adequate ventilation.
2. Set the parking brake if one is provided.
3. Remove power to the control panel by pressing the
red "OFF" button. If the machine is equipped with
a key switch, turn the key counterclockwise to the
"OFF" position.
4. Before charging the batteries, the battery
compartment needs to be vented. To vent the
compartment, the recovery tank needs to be
propped open.
WARNING: Before raising or removing the
recovery tank, be sure tank is
empty. 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.
5. The FOCUS 17/20 is equipped with an on-board
charger located behind the recovery tank (See
Figure 17). The charger is a 3-stage charger
designed to maximize battery life. The AC power
cord to the on-board charger is located in its
storage compartment under the control handle at
the rear of the machine (See Figure 16). Pull the
cord out of the storage compartment.
6. Connect the charger to a properly grounded single
phase (3-wire) wall receptacle. NOTE: When the
charger is plugged into the wall receptacle, the
yellow light will be illuminated on the control panel
next to the plug symbol and the charger with begin
charging (see figure 3, item A).
3-Stage Charging Sequence:
•
Bulk Stage - In the bulk stage of charging, the
red light is illuminated on the charger (See
Figure 17). During this stage the charger is
supplying its full amp output to the batteries. It
will continue to charge the batteries at this rate
until the batteries reach approximately 75% of
their capacity.
