Tipping the Brush Deck
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.
Raise the oor-tool for transit or lower for cleaning opera-
tion using the lifting handle tted to the back of the machine
(Fig.11).
For tting the oor-tool blades (See Page 13).

The TT Range are all equipped with a 40 litre clean-water tank allowing large areas to be cleaning in a single ll.
Filling the clean-water tank
Ret vacuum hose to the Floor-tool when nished.
The vacuum hose has a U-bend clip which creates a U-bend in the hose preventing water spillage when the vacuum is switched o. If
you need to remove the U-bend clip for any reason always ensure it is retted correctly before you resume operation (Fig 36-39).

Fitting the Hose Guide
Note:
DO NOT push the vacuum hose onto the Floor-tool with the Floor-tool in the raised position.
Raise oor-tool again before driving to the cleaning area. !!
Note:
Great care must be taken to ensure that contaminants (leaves,hair, dirt, etc) 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.

The large cap on the left can be
removed for lling from a bucket or
suitable container (Fig.13).
To ll the clean-water tank, use the
FLEXI - FILL pipe from either a tap or
hose pipe (Fig.12).
Fill the clean-water tank
to a maximum of 40 litres,
including cleaning chemicals
if required. Follow chemical

Lowering the floor-tool
Pre-scrub mode
The TT Range 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, allow the chemical time to work, then scrub the area a second time
with the oor-tool lowered.
Floor-tool in use
Breakaway floor-tool
The clean-water / chemical mix is
dispersed via the ‘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.15).
If streaking occurs, wipe the oor-
tool blades clean (Fig.16).

After preparing the oor (see previous
section), we are now ready to set the
controls to suit the cleaning conditions.
Before any settings can be applied,
ensure the brush deck is lowered.
Move the oor-tool lever (see Fig.17),
to it’s lower position (see Fig.18).
Note: The machine will still reverse
withthe oor-tool in the lowered
position, this could possibly damage
the blades. Raise the oor-tool before
reversing.

The oor-tool design incorporates a safety knock-o feature.
Allowing it to safely disengage from its mounting should it
become caught on an obstruction, during forward machine
movement.
To re-attach the oor-tool blade to its holder, rst loosen the retaining
knobs on the oor-tool body and slide onto the
holding bracket.
Tighten retaining knobs to nger tight (See Fig.19).

Note:
Care must be taken to reduce speed when cornering or when
manoeuvring around obstacles.
