SIDE SKIRT MAINTENANCE
The side skirt’s 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 skirts. A height adjustment can easily be made to lower the
blades so that all the water can be pick-up by the squeegee.

1
See Figure 12. Loosen the (2) side skirt Retainer Knobs (AA) (2 per side) and remove the Skirt Assemblies (BB) from the scrub deck. NOTE: Remove the
skirts by fi rst sliding them forward and then pulling them off.
2 Remove all the hardware that holds the blades to the skirt housings. NOTE: The main blade on each skirt housing is held on with Tool-less Retainers. Simply
loosen the large Wing nuts (CC) and then turn the Knobs (DD) on the outside of the skirt housing until they are horizontal and push through the slots. The
small inside Blade (EE) on disk models is held on by (2) screws and nuts and has 2 working edges.
3 The main skirt blade has 4 working edges as shown. Turn the blade so a clean, undamaged edge faces toward the center of the machine. Replace the
blades as a set if all 4 edges are nicked, torn or worn beyond their ability to be adjusted.
4 Reinstall the skirt housing assemblies onto the machine and adjust the blade for proper contact to the fl oor when the brush deck is placed in the scrub
position.
SIDE SKIRT HEIGHT ADJUSTMENT
1 The side skirt housing knob retainer screw studs have leveling Adjuster Collars (FF) that can be raised or lowered to compensate for blade wear.
2 To adjust, remove the Skirt Assemblies (BB) from the scrub deck to access the Adjuster Collars (FF). Adjustment Tip: The skirts Retainer Knobs (AA) can be
loosened with skirts left on and the Adjuster Collars (FF) rotated by reaching under the skirt housing.
3 Turn the Adjuster Collars (FF) (Up or Down) to where the blades just fold over enough when scrubbing that all the waste water is contained inside the skirting.
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.
