To operate machine:
1. Switch the key of the main power supply to the position of ON(I).
2. Pull down the squeegee lifting rod to lower the squeegee to the ground.
3. Step on the brush head lifting pedal or press the Brush Switch to lower the brush head.
5. Press the vacuum motor switch (20” Model only).
6. Motor drive models: adjust the speed control knob to the desired cleaning speed.
7. Each cleaning path should overlap by 2in.
8. Keep the machine moving to avoid damage to the oor.
9. If there is a drag mark on the ground after the squeegee, lift and clean the squeegee.
10. Do not operate the machine on the slope with a slope over 5% (3°).
11. Use the “double scrub” method to clean extremely dirty areas. Lift up the squeegee and scrub the
oor back and forth, the re-lower the squeegee for waste recovery.
12. Replace or rotate the pad or brush as required.
13. Observe the power consumption of the battery indicator.
14. Observe the amount of solution in the solution tank. In traditional scrubbing, the typical con-
sumption is about 2.5 gallons every 10 minutes.
15. When the solution in the solution tank is empty, empty the recovery tank rst, then rell the
solution tank.
16. When nished cleaning, stop and place the machine on the level ground, turn o and take key.
