Pre-scrub mode

The TTB 4055/100T has been designed to cope with a variety of floor types and different levels of soiling.
On heavily soiled floors use a 'double scrub' technique.
First pre-scrub the floor with the floor-tool in the raised position, allow the chemical time to work, then scrub the area a
second time with the floor-tool lowered.
Ref to (Fig.25) to raise and lower the floor-tool.
Floor tool in use
The clean-water / chemical mix is dispersed via the 'THRU-FEED' system.
The waste water is then retrieved by the floor-tool.
Overlap the scrubbing path by 10cm to ensure an even clean (Fig.28).
If streaking occurs, wipe the floor-tool blades clean (Fig.29).
Breakaway floor-tool
Note: The machine will still reverse with the floor-tool in the lowered position, this could possibly damage the blades.
Raise the floor-tool before reversing.
Note: Care must be taken to reduce speed when cornering or when manoeuvring around obstacles.

movement.

onto the holding bracket.
