Fit the oor tool and retain using the
detent pin.
Push vacuum hose onto the oor tool;
ensure a tight t.
NOTE: DO NOT push the vacuum hose
onto the oor tool with the oor tool in
the raised position.
Raise the oor tool for transit or
lower for cleaning operation using
the lifting handle tted to the back
of the machine.
For tting the oor tool blades (See P12).

ALWAYS ENSURE THAT THE MACHINE IS SWITCHED OFF
BEFORE MAKING ANY ADJUSTMENTS !!
2 x 370mm Brush or a 2 x 360mm Pad on
the TGB 8572. Featuring the Nulock brush
system. The brush is simply pushed and
twisted to lock, making tting and removal
a simple process.
Slide the brush / pad under the brush deck.
Fit the brush / pad onto the Nulock drive
chuck, twist to lock the brush / pad in
place.
LH Bias: If the machine pulls
to the right, turn the knob
clockwise to apply left hand
bias to the brush deck.
RH Bias: If the machine pulls to
the left, turn the knob counter-
clockwise to apply right hand
bias to the brush deck.
Turning the knob
clockwise will make
the machine pull
more to the left.
Turning the knob
counter-clockwise
will make the
machine pull more

Fitting the Brush / Pad.
Brush Deck Pitch Adjustment
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.
If the machine has a tendency to pull to either side while cleaning
forwards, this can be compensated for by turning the brush deck
pitch adjustment knob.

Note: Safety gloves are recommended for the changing of used brushes.

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.
Fitting the Hose Guide
NOTE: DO NOT push the vacuum hose
onto the oor tool with the oor tool in
the raised position.

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 TGB 8572 is equipped with a large capacity clean water tank allowing for
large areas to be covered in a single ll.
Filling the Clean Water Tank

To ll the clean water tank, extend the hose located to the rear of the machine in the centre of the removable ller cap (1). Pull out
hose. Open the stopper and place hose under water tap, or use a hose to commence lling. The tank can also be lled by unscrewing
the ller cap and using a bucket or similar container (2).

The control for lowering the brush deck can be found to the rear right of the machine.
Lower the brush deck by moving the left hand release lever to the upper position.
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 to its lower position.
NOTE: Do not drive the machine
backwards with the oor tool in the
lowered position, this could possibly
damage the blades.
Raising/Lowering

Machine Operation
Raising/Lowering the Brush Deck
Insert the key, turn the main control on / o key to position ‘1’.
(Fig.A) The traction status light will illuminate.
Set desired traction speed as required, depending on oor type
and level of soiling (Fig.B).
Middle speed is the optimum cleaning speed.
Set the ow rate (Fig.C).
The TGB 8572 is equipped with an electronic braking system.
Simply release the hand operated start / stop trigger and the
machine will stop.
In an emergency, strike the Emergency Stop button. (Fig.D).
The machine will be disabled.

Machine Operation
The brush load lever is located to the right hand side of the machine.
This option is for hard to clean patches, adding extra pressure to the brushes.
NOTE: It is recommended this option is NOT used all the time and is for spot cleaning only.
The run-time of the machine may decrease if the load on the brushes is increased.
Brush Pressure / Load Adjustment
To operate, set water ow rate, lower brush deck, lower the oor tool, press the vacuum switch, pull brush On/O trigger.
Adjust the speed to suit the conditions using the variable speed control,depending on oor type and level of soiling.
Middle speed is the optimum cleaning speed.
The waste water is then retrieved by the suction oor tool.
Overlap each scrubbing path by 10cm to ensure an even clean.
Do not operate the machine on inclines that exceed (6%) when full.
Warning: While on ramps or inclines, avoid sudden stops.Avoid sharp turns. Use low speed down ramps.
Clean only while descending (driving down) the ramp.
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.
If streaking occurs wipe oor tool blades clean.
NOTE: Care must be taken to reduce speed when cornering or when manoeuvring around obstacles
The oor tool design incorporates a
break-away 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 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.
