The replacement of rear squeegee bladesMonday, October 30, 2017
Replacing rear squeegee blades on scrubbers and/or sweeper scrubbers isn’t that difficult if you stay within the procedure guidelines. If we are discussing American-Lincoln, PowerBoss, Windsor or Karcher the procedure is generally the same or at least similarly close enough to follow from machine to machine. I also would conclude that the walk-behind scrubber’s instructions for replacement of squeegee blades could also be adapted for use on a rider scrubber. So, I would call these my universal instructions for such a service procedure. So let’s begin this procedure.
1. First, I would mention to examine the existing blades on the machine for damage such as tears or rips in these blades. What this does is to allow the dirty water debris to flow through the blades out the back of the machine. You can notice this event by occurring water streaks when the machine is in scrubbing motion. These streaks can be very dangerous to the surrounding workers and can result in a fall or a collision with another vehicle such as a forklift or personal carrier.
So now we have determined that the blades need to be replaced.
2. For safety, before servicing the machine, stop on level floor, set parking brake and turn off the machine.
3. Disconnect the rear vacuum hose that is connected to the rear squeegee assembly.
4. Remove both mounting knobs that hold the squeegee assembly in place.
5. Turn on the machine and raise the squeegee assembly. Now turn off the machine.
6. Now remove the squeegee assembly. This should be as easy as lifting up and out away from the machine.
7. Once the squeegee assembly is off the machine, you will want to lift it to some type of work table for easy disassemble.
8. Loosen the rear squeegee retainer band tension latch and open the retaining band.
9. Remove the rear squeegee.
10. Install the new rear squeegee blade. When installing, make sure all of the holes or slots in the squeegee are over the pins or tangs on the squeegee frame.
11. Tighten the rear retaining band tension latch.
12. Loosen the front retainer band latch as you did the rear and open the retaining band.
13. Remove the front squeegee blade.
14. Again, remember to match the hole or slot on the blade to the pin or tang on the rear squeegee frame.
15. Install the new front squeegee blade.
16. Reattach the band and tighten it with the tension of the latch.
17. Reinstall the squeegee assembly back onto the machine.
You are now finished with this installation. To keep up with the maintenance of these, they should be checked daily for wear and tear after using the machine. Replace as required. The side squeegees are the same process as the rear and should also be checked at the same time.
One thing we haven’t discussed is the type of squeegee blade you are using. You may not be satisfied with the wear of the squeegee or pick-up of the dirty water of your scrubber. There are four basic squeegee materials being used today by many of the scrubber OEM’s. They are tan gum rubber, Linatex®, neoprene and urethane. These materials have specific applications so you may be using the wrong material for your application. You may need a squeegee check-up and I can help with that. You can e-mail me with your situation and we can discuss your options.
I hope you have learned something new today and, as always, thank you for reading.
