How To Clean A Floor

WARNING: Water solutions or cleaning materials used with this type of machine can leave wet areas on the floor surfaces. These areas can cause a dangerous condition for the operator or other persons. Always put CAUTION signs near the area you are cleaning.

To clean a floor follow this procedure:

1. Set the parking brake (if equipped with machine.)

2. Put the water and a cleaning chemical in the clean solution tank.

3. Release the parking brake (if equipped with machine.)


5. Lower the squeegee.

6. Activate the brush switch until correct pressure is achieved.

WARNING: This machine is capable of maximum head pressure with worn pads or brushes. With this feature, there is the possibility of exceeding the recommended brush pressure on new pads or brushes. This will either create reoccurring circuit breaker tripping or the possibility of lost traction and control. The brush switch should be activated to accomplish only enough brush pressure for the job. This will allow longer battery life and cleaning time.

NOTE: Keep the machine moving when the brush is rotating on the floor. Pre-wet brush/pad or keep light pressure on brush until solution flow is adequate to keep brush/pad from scratching the floor.

To pre-wet brushes you should first turn the speed knob to the lowest setting on the "L" model. Then on both the "S" and "L" models, lower brushes until brushes are just touching the floor.

Activate the forward/reverse switch to start motor and solution flow.

7. Turn the solution knob to the right to activate the flow of solution. Adjust the flow of clean solution to the flow desired.

8. Move the machine across the floor in the forward direction.

9. Make a 180° turn.

NOTE: When you make more passes across the floor, let the brush clean approximately 2 inches (5 cm) of the area already cleaned by the brush.

NOTE: During most cleaning procedures, apply and remove the solution in one operation.

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.
