are not allowed to enter the clean-water tank during the lling process.
If using a bucket or similar, ensure it is always clean and free from debris.
Machine Set-Up
Fitting the Floor Tool
The oor tool has been designed for quick tting, allowing easy squeegee blade replacement and a safety knock-o󰀨
feature if the oor tool gets snagged, whilst in transit.
Note: It is easier to t the oor-tool if the weight of the machine is resting on the brush.
Ensure the brush is tted rst.
Note: The lever moves upward and backward motion to lock the oortool in the raised position.
The oor tool carrier can be
raised and locked from moving
by operating the locking lever,
upwards and backwards.
This lever can be found next to
the lower section of the handle.
Unlock and swing the oor tool
carrier to the side of the machine
(Fig 8).

Note: The lever moves upward and backward motion to lock the oor tool in the raised position.
Machine Operation
Pre-scrub mode
The HT1840 & TT1840 have been designed to cope with a variety of oor types and di󰀨erent 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).

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).

After use, empty waste water tank using
emptying hose and ush out with clean
water. A
Remove the two hoses and disconnect the
separator from the machine (Fig 26). Undo
the separator restraining strap (Fig 26a) and
lift o󰀨 the separator. The separator has a
sealing rubber which should be examined at
every clean down (Fig 27).
Rinse using clean water.
Note:
Avoid over tightening the clean water draining cap.
The HT1840 & TT1840 have been designed with ease of use in mind, this included easy stripping down and cleaning.
Remove the two lters clipped into the separator and ush with clean water (Fig 28)(Fig 29).
Replace by tting the rear of the lter rst then clipping the front to lock in place (Fig 30) (Fig 31).
Once emptied the top waste water tank can simply be lifted o󰀨. (Fig 32).
The clean water tank can be drained via the yellow cap tted to the left
hand side of the machine. The cap has a rubber seal and might require a
spanner to remove. (Fig 33).
