How to Clean a Very Dirty Floor
To clean a very dirty floor, follow this procedure:
1. Apply solution to the floor.
2. Do not lower the squeegee. This will keep the vacuum
motor off.
3. Lower the brush or pad and scrub the floor.
4. Scrub the floor again with additional solution and
lower the squeegee.
5. Pick up all the solution with the squeegee.
Do These Procedures When You End Your Work Period
Having finished the job and before any type of maintenance
is done, follow these procedures:
For one touch cleaning shut down process, press and
release the one touch button.
For manual shut down follow these procedures:
1. Turn the solution flow off by decreasing the flow to its
minimum position.
2. Press the brush up/down switch to the up position
until the brush head has reached its up most position.
3. Place the squeegee up/down switch in the up position
to raise the squeegee and allow the vacuum motor to
continue to run. The vacuum motor will run for another
20 seconds and then place the squeegee up/down
switch to the up position. This will shut the vacuum
motor off.
4. Take the machine to a water drain.
5. Turn the key switch “OFF”.
6. Remove the drain hose from the holding hook.
7. Put the end of the hose over a drain or bucket.
8. Turn the valve housing to the left (see figure 34).
9. To open the valve completely, turn the housing fully to
the left. Pull the housing off of the valve.
10. Empty the recovery tank. NOTE: When hose is
lowered below water level, water will flow.
WARNING: Use gloves to protect your hands
from contact with dangerous
solutions when preforming the steps
listed above.
