13. FRONT SQUEEGEE
The front blade allows solution to pass through channels in the blade into the squeegee assembly while maintaining vacuum to provide lift. The front blade has two wear surfaces and can be rotated for extended life. The front blade should not require regular replacement under normal use.
The rear blade wipes the floor to a near dry condition. It is important the rear blade be in good condition to properly do its job. As with the front, each squeegee blade assembly has two wear surfaces for extended service.
Check both the front and rear squeegee blades for damage, wear, and adjustment each day in the pre- run check. Change the front blade if it is torn or has an uneven edge. Change the rear blade if it is less than 1/2 the original thickness.
