To prevent an explosion, charge the batteries only in an area with good ventilation. 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. Before charging the batteries, the battery compartment needs to be vented. 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 Scrubtec is equipped with an on-board charger located behind the recovery tank (See Figure 17). 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). 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.
