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-off
feature if the oor tool gets snagged, whilst in transit.
Raise the oor tool for transit or lower for cleaning operation using the lifting
handle tted to the back of the machine (Fig 11).
For tting the oor tool blades (See Page 13)
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.
Fig 11
Fig 10
Fig 9
Fit the oor tool and retain using
the detent pin (g 9).
The lifting strap is held by a
detent pin (Fig 10).
Note:
Raise oor-tool again before driving to the cleaning area
Tipping the Brush Deck
To tip the deck into the down position
(Operating mode). Press in the brush
deck locking bar (Fig 7) and rotate the
brush deck (Fig 8).
To change to brush deck up position,
(Transit mode) simply lift the deck and
the sprung loaded locking bar will active
to hold the deck up. Fig 8

The water level in the clean water tank can be seen using the clean-water clear
dump hose tted to the rear of the machine.
The clean water bottom tank holds 40 litres.
Machine Set-Up
Control of Substances Hazardous to Health (COSHH)
For best results use a non-foaming type of chemical, dilute to the manufacturers specication.
For further guidance on hazardous substances refer to health and safety instructions online.
Visit http://www.hse.gov.uk/ for UK information.
Important
Do not operate machine unless the Operator Manual has been read and fully understood.
!!
WHEN HANDLING AND MIXING CHEMICALS.
Always ensure that chemical manufacturers safety guidelines are followed.
Only use chemicals recommended for use in auto scrubber-dryers.
! !
Note.
Great care must be taken to ensure that contaminants (leaves,hair, dirt, etc) are not allowed to enter the
clean-water during the lling process.
If using a bucket or similar, ensure it is always clean and free from debris.
Clean water level
The TT / ET 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
To ll the clean-water tank, use the 1 meter FLEXI
- FILL pipe from either a tap or hose pipe (Fig 12).
The large cap can also be unscrewed for lling
from a bucket or suitable
container.
Fill the clean water tank to a maximum of 40 litres,
including cleaning chemicals if required.
Follow chemical manufacturing guide lines.
The clear Dump hose at the rear of the machine can be used to see the level of the clean water.

Lowering the oor tool
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 Floor tool lever (see g.16), to it’s lower position (see g.17).
Note: The machine will still reverse with the oor tool in the lowered position, this could possibly damage the
blades. Raise the oor tool before reversing.
Fig.17
Machine Operation
Pre-scrub mode
The TT / ET Range have 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, allow the chemical time to work, then scrub the area a
second time with the oor-tool lowered.
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 14).
If streaking occurs, wipe the oor-tool
blades clean (Fig 15).
Floor tool in use

Breakaway oor-tool
Fig.18
The oor-tool design incorporates a breakaway feature.
Allowing it to safely disengage from its mounting should it
become caught on an obstruction, during forward machine
movement.
To re-attach the blade to its holder.
First loosen the retaining knobs on the oor-tool body and slide
onto the holding bracket.
Tighten retaining knobs to nger tight. (See g.18)
Note Care must be taken to reduce speed when cornering or when manoeuvring around obstacles.

ALWAYS ENSURE THAT THE BATTERY IS DISCONNECTED
PRIOR TO ANY MAINTENANCE OPERATION
! !
After use, empty waste-water tank using
emptying hose and ush-out with clean
water (Fig 19).
A
Remove the two hoses to disconnect the separator from the
machine (Fig 20).
Lift off the separator. The separator has a sealing-rubber
which should be examined at every clean-down (Fig 21).
Rinse using clean water.
The TT / ET Range has been designed with ease of use in mind, this included easy stripping-down and cleaning.
Remove the lter tted into the separator and ush with clean water (Fig 22)(Fig 23).
Placed into the top tank is grey lter basket, clean and ush with clean water (g 24) (Fig 25).
A
Regular Maintenance
The Bottom (Clean Water) tank is attached to the chassis and should only
be removed by a competent service engineer (Fig 26).
Clean by ushing with clean water if required.
Excess water can be drained using the clear dump hose tted to the rear
of the machine.
Located under the left hand side is a clean water lter, ensure the clean
water tap is turned off before removing this lter (Fig 27).
Clean and ush with clean water if required.

To clean the oor-tool, remove securing-pin and disconnect the lifting strap and remove the oor tool securing pin
pull-free the oor tool from the rear of the machine.
Rinse the oor-tool assembly with clean water and ret.
Periodically the oor-tool blades should be examined and checked for wear and damage.
The blade removal is easy. Simply start by removing the four retaining pins (see Fig 28), turn the oor-tool over and
separate the blade carrier from the body (see Fig 29). Peel away the blades from their locating lugs (see Fig 30) and
examine or renew as required.
Replacement is a reversal of the removal process.
