SIDE BLADE MAINTENANCE
The side blades' function is to channel the waste water to the squeegee, helping contain the water within the machines cleaning path. During
normal use the blades will wear in time. The operator will notice a small amount of water leaking out underneath the side blades. A height
adjustment can easily be made to lower the blades so that all the water can be picked up by the squeegee.

SIDE BLADE HEIGHT ADJUSTMENT
DISC -
1 See Figure 4-6. The side blade assembly knob removal screw studs have leveling Adjuster Collars (AC), that are to be raised or lowered to
compensate for blade wear.
2 Make sure the machine is on a level surface.
3 Lower the scrub deck by pressing the One-Touch Scrub Switch (M) and drive the machine forward a short distance to ensure the blades fold
over.
4 Observe blade fold over.
5 The side blade Removal Knobs (16) can be loosened with assembly left on and the Adjuster Collars (AC) rotated by reaching under the blade
assembly.
6 Turn the Adjuster Collars (AC) (Up or Down) to where the blades just fold over enough when scrubbing that all the waste water is contained
inside the scrub deck.
Note: Make small adjustments to obtain good blade wiping. Do not lower the blades too much to where they fold over excessively and cause
unneeded blade wear.
