1. Push the machine to a level floor.
2. Ensure that the machine is off.
3. Turn the recovery tank lid (A, Figure14) 90degree position where it can be taken off from the recovery tank, and then take out the
float ball filter (B) from the recovery tank lid.
4. Clean the recovery tank lid (A), recovery tank (C), clean solution tank(D) and the float ball filter(B). Empty the recovery tank with
the drain hose (D, Figure 10).
5. Install the float ball filter (B) and the recovery tank lid (A).
6. Inspect the integrity of the tank sealing strip.
NOTE
The tank sealing strip (E) produces the vacuum inside the tank when the vacuum motor works. The tank must
be sealed so it can effectively absorb the water from the ground to recovery tank.
7. Check whether the contact surface of sealing strip (E) has integrity and sealing is sufficient. If necessary, take the sealing strip of
the tank out of the groove (F) and replace it. Assemble the new sealing strip as shown in (Figure 14), the joint should be back in the
middle area.
8. Close the recovery tank lid (A).
