Pre-scrub mode

The TTB-1840 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 (Fig 21), allow the chemical time to work, then scrub
the area a second time with the floor-tool lowered.
To raise the floor-tool, ensure the floor-tool carrier is central to the machine (Fig 22).
Lift the lever near the base of the handle and lock into position (Fig 23).
Note The lever moves upward and backward motion to lock the floortool in the raised position.
Floor tool in use
If streaking occurs, wipe the floor-tool blades clean (Fig 25).
Note
Care must be taken to reduce speed when cornering or when manoeuvring around obstacles.

The clean-water / chemical mix is dispersed via 'THRU-FEED'
system.
The waste water is then retrieved by the floor-tool
(see page 9).
Overlap the scrubbing path by 10cm to ensure an even clean
(Fig 24).
