Maintenance and Adjustment
Squeegee Blade Cleaning and Inspection
Periodically clean and inspect the squeegee
assembly and blades.
1. Loosen the two thumb nuts (A), and slide the
squeegee assembly off the lift mechanism.
2. Clean the squeegee blades (B&C) and suction
area between the blades (D) with soap and
water.
3. Inspect the squeegee blades for nicks, tears,
and worn leading edges. If a squeegee blade
is worn or damaged, it may be turned around
with a fresh edge facing down/forward
up to four times before complete blade
replacement is required.
Squeegee Tilt Adjustment
The squeegee tilt should be adjusted when the
squeegee blades are replaced, or if the squeegee is
not fully wiping the oor. Misadjustment symptoms
include water streaks at the center or edges of the
squeegee path.
1. Park the machine on a at, even surface and
lower the squeegee.
2. Without moving the machine (which will cause
the rear squeegee blade to bend backward),
inspect the interface between the edge of the
rear squeegee blade and the oor. Inspect for
gaps at either the center or the edges.
3. If adjustments are necessary, loosen the turnbuckle jam
nut (B).
4. Lengthen (clockwise) or Shorten (counterclockwise) the
squeegee tilt Turnbuckle (A) to level the squeegee across
its length.
• If there is a gap in the center, lengthen the
turnbuckle.
• If there are gaps at the outside, shorten the
turnbuckle.
5. Retighten the jam nut.
