BRUSH PRESSURE AND BRUSH WEAR
Factors affecting brush wear are type of bristle, bristle, area, and
load on the bristles. See your authorized distributor for the type
of brush and bristle most suitable.
Brush pressure may be adjusted by adding or removing
counterbalance springs. The counterbalance springs are located
on the underside of the tractor foot rest.
The pressure will vary as follows:
No. of Springs
Pressure per Brush
0
353.8 lbs.
1
315 lbs.
2
291.4 lbs.
3
272 lbs.
4
252 lbs.
Adding springs will decrease scrub brush load. Shorter brush life
can be expected as the scrub brush pressure is increased.
REAR SQUEEGEE
The squeegee will require service when the inner edges of the blades become round with wear, impairing the wiping action or water
pickup. To service the rear squeegee use the following steps:
1. Loosen the aluminum knobs ( these hold the squeegee tool to the squeegee support).
2. Remove the squeegee tool and turn upside down to service the blades or caster wheels. The squeegee blades are designed to
fl
ip over and use another unworn edge.
To service the blades:
1. Loosen the clamp bolts.
2. Loosen far enough to slip the end clamp brackets off the squeegee tool. This will allow
fl
ipping the blades or installing new
blades.
3. Install blades so that outer blade is 3/16” longer than inner blades by assembling the top edge of the blade against the squeegee
tool weldment.
4. Reinstall squeegee clamp band and tighten clamp bolt tight.
