Double Scrubbing - HAKO PowerBoss Nautilus User Manual

DOUBLE SCRUBBING

Double scrubbing is an eff ective way to remove heavy grime
accumulation. This is accomplished by making two passes
over the area to be cleaned, the fi rst pass with the squeegee
raised.
Note: When double scrubbing it is necessary to manually lock
the side squeegee blades (and if equipped, the side brush
squeegee blade) in the raised position.
1. Manually lock both side squeegee blades in the raised
position. Open the scrub brush door. Lift the side
squeegee assembly and rotate the lock arms counter-
clockwise until they latch and lock the squeege blade in the
raised position. See Fig. 1.
2. If the machine is equipped with the optional side scrub
brush, raise the side brush squeegee blade by removing
the squeegee retaining strap, relocating the squeegee
blade using the lowest positioning slots (highest squeegee
position), then replacing the squeegee retaining strap.
See Fig. 2.
3. Start the engine.
4. To begin double scrubbing fi rst set the squeegee switch in
the "off " position (an illuminated red light on each switch
indicates that that function is turned off ). This will turn off
the vacuum fan and prevent the squeegee from lowering.
