Pre-scrub mode
The TTB 1840 has been designed to cope with a variety of oor types and different levels of soiling.
On heavily soiled oors use a ‘double scrub’ technique.
First pre-scrub the oor with the oor-tool in the raised position (Fig.21), allow the chemical time to work, then scrub the area
a second time with the oor-tool lowered.
To raise the oor-tool, ensure the oor-tool carrier is central to the machine (Fig.22).
Lift the lever near the base of the handle and lock into position (Fig.23).
The clean water / chemical mix is
dispersed via the ‘THRU-FEED’ system.
The waste water is then retrieved by the
oor-tool (see page 9).
Overlap the scrubbing path by 10cm to
ensure an even clean (Fig.24).
If streaking occurs, wipe the oor-tool
blades clean (Fig.25).

NOTE: Care must be taken to reduce speed when cornering or when manoeuvring around obstacles.
Note: The lever moves upward and backward motion to lock the oortool in the raised position.
