CMK 1-12-2015
This instruction sheet explains how to install the rear squeegee inner strap retainer 731375.
Required material:
Inner strap retainer 731375 – Quantity 1
Reference manual pages:
Squeegee group 730118
Squeegee linkage group 730158
Purpose:
The purpose of the retainer is to prevent the inner squeegee band from being pulled away from the
squeegee rubber.
Installation:
1. Remove the rear squeegee assembly from the scrubber.
2. Remove the two squeegee retaining knobs 3343814 and two washers 3401543 from the
squeegee assembly.
3. Set the retainer plate 731375 in place over the two squeegee mounting studs 3343903. The
bent flanges on the retainer plate should be positioned just in front of the inner squeegee strap
and latch.
4. Replace the two washers 3401543 onto the squeegee mounting studs with the concave side
facing down.
5. Replace the two knobs 3343814.
6. Install the squeegee assembly onto the machine being sure that the two washers are positioned
above the squeegee mounting plate and the new retaining plate is positioned below the
squeegee mounting plate.
7. Tighten the retaining knobs.
8. Important: With the retaining plate installed the squeegee is now positioned 3/16” lower in
relation to the squeegee casters so it is necessary to readjust the casters to achieve the correct
squeegee flair.
