4. Brush pressure. You can vary the pressure on Model 40 with the dash
board button. Use as little pressure as will do the job. Excessive pressure
will shorten the machine's run time on a battery charge, can shorten the life
of your brushes, and could even damage some floors.
5. Chemical Residence Time on the Floor. Scrubbing slowly may improve the
scrubbing job you do. By scrubbing slowly, the brushes stay longer over
each square yard of surface, and so scrub more, and the chemical stays
longer on the floor before being picked up by the squeegee.
For especially bad spots, you can "double-scrub". To double-scrub, leave the
vacuum squeegee up and off. Scrub back-and-forth several times until the grit and
grime on the floor has been loosened. Then vacuum it and the solution up.
6. Adjust that Squeegee! When your machine was new, it scrubbed and picked up
perfectly--the best in the business. How's it picking up now? Not so hot? Then
you should check the following:
A. Blades in good shape? The rear blade on the squeegee is especial-
ly important. It can be reversed front to back and from top to bottom,
and so can be rotated four times. Look at the condition of the rear
rubber's leading edge. If still sharp, it should work well for you. If
worn flat, it will smear like an old windshield wiper blade. (See
squeegee section of this manual for info on how to rotate the blades).
B. Pitch angle? The rear corners of the back blade of the squeegee
must both touch the floor. Otherwise, the squeegee will only pick up in
the middle of its path. To adjust, turn the knob. (See
Squeegee Sec-
tion of this manual--Page 19).
C. All Clear? Scrubbers pick up strange stuff, and lots of it. Is your
recovery tank cleaned out? Is the path clear inside the squeegee? In
the hose? In the inlet to the tank? Remove the vac motors and check
the foam filters under them.
