FloorCare
The 1840 has been designed to scrub and dry a variety of hard oors.
This machine has not been designed to pick up large objects, make sure you pre-sweep the oor before use.
For optimum performance make sure you keep the lters, hoses and oor tool blades clean and free from debris.
Disconnect from the power supply or remove the battery BEFORE commencing maintenance or cleaning of your machine.
After every time the machine is used.
The machine should be left in a clean and tidy state, drain
all uids, clean all lters, pipes and place the
battery on charge.
It is recommended you strip and
thoroughly clean the machine and its
components regularly.
At least weekly to avoid operating
troubles and machine breakdowns.

Fitting the brush...
Index page...
The machine uses a 400mm brush or a
360mm pad drive.
Filling tank...
Fill the clean water tank to a maximum
of 18 litres including chemical if required.
Fill gauge...
Fitted to the clean water inlet is a red
plastic ll gauge, this rises as the tank
lls.
Moving when full...
When the clean water tank is full the machine
can be tilted to a maximum of 450 without
spillage.
Take care to make sure that contaminants (leaves, hair, dirt, etc.) are not allowed to enter the clean water tank.
Fitting the Floor Tool...
Make sure the inspection cap is in place on the
uid pipe.
Swing the oor-tool carrier to the side of the
machine.
Secure to the carrier using the two knobs tted
to the oor-tool carrier
Do not over tighten the retaining knobs.
Fit the brush pad onto the Nulock drive
and twist to lock in place.
Saftey Gloves are recommended for
changing used brushes.
Remove the ller cap and ll using a hose,
bucket or suitable container.

Water Flow Adjustment...
Located on the left of the machine is the clean
water tap, make sure the tap has been turned
on before use.
Ideally set the tap to 45% this enables the
cleaning solution to last the same time as a fully
charged battery..

Raising and lowering the Floor Tool...
To raise and lower the oor tool make sure the
oor tool is central to the machine.

Index page...
Whilst the brush motor is running press the water ow On / O Button for uid control (Fig.C), the clean water On / O tap must
be open.
Ideally set the tap to 450 this enables the cleaning solution to last the same time as a fully-charged battery.
When the Triggers are released the brush motor and the cleaning solution pump will switch o, the vacuum motor will continue
for 10 seconds.
Press the mode select button to operate the brush only (Fig.D).
The start sequence is required in this mode.

Drain Top (Waste) Tank
Use the drain hose to empty the top tank and ush the tank through with clean water, it is
advisable to let the tank air dry, by removing the separator, if leaving your machine for extended
periods of time.
Drain Bottom (Clean Water) Tank
The clean-water tank can be drained via the yellow cap tted to the left hand side
of the machine. There is a sealing bung beneath the yellow cap (ensure the sealing
bung is clean) The cap should only be done up by hand.
Drain the clean water tank if leaving your machine for a extended period.
The cap has a rubber seal and might require a spanner to remove.
Regular Maintenance...
Located under the clean water inlet is the clean water lter.
Cleaning chemicals residue can cause the lter to become blocked causing
poor water ow.
Remove the clean water inlet (g 1).
In the bottom of the tank is the clean water lter, clean the lter regularly (g 2).

Storage ...
Numatic recommend you leave your 1840 resting on the brush if leaving your machine for
short periods of time.
This saves distorting the squeegee blades.
Remove the brush and oor tool if you are leaving the machine for extended periods of
time.
After every time your machine is used, we recommend you drain all uids, clean all
lters, pipes and place the battery on charge.
The machine should be left in a clean and tidy state.

The battery charge level meter displays the charge level of the batteries; when fully charged, all meter lights are illuminated.
As the machine is used and the batteries are discharged, the battery charge level meter lights will go out from top to bottom.
If the battery charge level is allowed to discharge to the point that only one red light remains illuminated, the operator should charge the battery.
The battery supplied for this machine allows for a run time of 45 mins approx (Hi Mode), when fully charged.
The battery pack must be fully discharged and recharged over a few cycles and brushes need to be worn in to achieve maximum eciency.
Charge time for a fully discharged battery, is approximately 6 hours.
The TTB 1840 come with its own stand-alone charger.
Connect the charger to a suitable power supply.
Once mains power is connected the red charging indicator will illuminate. To ensure a full charge, the battery should be left for a period of 6 hrs.
Once fully charged, disconnect the charger from the power supply and the charger lead from battery.
Note: Your charger will need resetting between subsquent battery charging, remove the charger from AC power supply to reset.
Use recommended PPE as required...
Please comply with your company’s COSHH risk assessments
(Make sure you wear the appropriate safety clothing).
Leave the machine empty and clean...
Open the separator and let the machine air dry...
Only leave the machine resting on the brush and oor tool for short periods of time...
