1. Unplug the hoses (20, 21) from the recovery tank (19).
2. Make sure the recovery tank is empty then lift it up.
3. Place batteries on the tray. Use the bracket to secure them. Position them correctly.
4. Connect all the cable terminals.
Caution: Make sure you connect RED (+) cable terminals to positive (+) posts and BLACK
(-) cable terminals to negative (-) posts. Machine will not operate if not connected properly.
Failure to do so will result in damage to batteries and possible explosion.

What to Do When You’re Operating The Machine
Vacuuming Up Solution
1. Make sure the squeegee is in the down position.
2. As the machine moves forward and solution is dispensed, the squeegee will vacuum it up into the recovery tank.
3. If necessary adjust squeegee pressure by turning knob (8).
If solution is missed, reduce the amount of solution ow, raise the squeegee and pull the machine back over the missed area.
Lower the squeegee and move the machine forward to pick up any remaining solution.
How to Control Excess Foam in the Recovery Tank
