Machine Operation
Pre-scrub mode
The HT1840 & TT1840 have been designed to cope with a variety of oor types and dierent 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).
21

23
The clean-water / chemical mix
is dispersed via ‘THRU-FEED’
system. The waste water is then
retrieved by the oor tool
Overlap the scrubbing path by
10cm to ensure an even clean
(Fig 24).
If streaking occurs, wipe the oor
tool blades clean (Fig 25).
