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.

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 retted 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.
Ret vacuum hose to the
Floor tool when nished.
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.
F
illing the Clean Water Tank
The TGB 1620 is equipped with a large capacity clean water tank allowing for large areas to be covered in a single fill.
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 water level in the clean-water tank
can be measured using the scale on the
left rear side of the machine. The clean
water bottom tank holds 60 litres.
NOTE: always ensure that the waste
water tank is empty before lifting.
