CAUTION!
If foam/liquid comes out of machine exhaust, switch off immediately.
Allow the accumulated liquid to drain out through the machine exhaust, check the waste water level, empty the
waste water container if full.
Immediately upon start up there will be a certain amount of liquid issuing from the machine exhaust which will be the
residue of liquid still within the power head. This will be quickly discharged after which the machine should function
normally.
Liquid ejected from the machine could be hazardous as a result of its temperature, pressure or chemical
content.
This machine is not suitable for the collection of biological hazards, hazardous or explosive dust. You should contact
your local distributor if you require a machine capable of performing these tasks.

When moving from one place to another, consider the weight of the machine.
Spray extraction maintenance/fault nding
If the vacuum cleaner stops working switch off and remove the plug from the wall, before investigating where the fault
lies.
If the vacuum cleaner has a blockage and will not pick up liquid, switch off and remove the plug from the wall.
Remove the dome and empty the liquid out of the waster water container.
If the waster water container is empty, check that the oor tool wands and hose are not blocked.
If no spray from nozzle the solution tank is empty, rell the solution tank.
Flush the system with clean water after use.
If the machine stops spraying then check the clean water tank level, empty the waste water tank and rell the clean
water tank as necessary.

Removing the dome and waste-water tank.
To remove the dome, unclip the locking toggles and lift
the dome off the machine (Fig 14).
The waste water tank is held into place with a red locking
clamp. Undo the clamp (Fig 15) and lift the waste water
tank from the machine (Fig 16).
Fig 14
Fig 15 Fig 16
Filling the Nuchem / water tank.
The NHL 15 is equipped with a large 15 litre NuChem / water tank allowing large areas to be cleaned in a
single ll.
To ll the clean water tank remove the waste water tank and ll using hose, bucket or a suitable container (Fig 17).
Fill to the MAX level mark (Fig 18) located on the inside of the drum.
Ensure the clean water goes into the container and not the central tube.
Note.
Great care must be taken to ensure that contaminants (leaves, hair, dirt, etc) are not allowed to enter the
NuChem / water tank during the lling process.
If using a bucket or similar container, ensure it is always clean and free from debris.
Caution:-
Avoid tipping water into the central tube this is leads directly to the vacuum motor (Fig 19).

Chemical usage.
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 HSE website.
Visit http://www.hse.gov.uk/ for UK information.
When handling and mixing chemicals.
Always ensure that chemical manufacturer’s safety guidelines are followed.
Only use non foaming chemicals when using this machine.
! !
NuChem 4 available for this product.
INSTRUCTIONS FOR USE
TEST FOR COLOUR FASTNESS
Find a small area on the material which is not normally on view and test the carpet / fabric
for colour fastness by rubbing the cloth dampened with correctly diluted NuChem 4.
FOR NORMAL SOILING:
Pour one 40ml measure into 5 litres of cold water.
FOR HEAVY SOILING:
Pour two 40 ml measures into 5 litres of cold water.
NuChem 4 is non-foaming, bactericidal, contains optical brighteners and leaves no tacky
residues in the fabric and is enhanced with both a delicate and discreet verbena scent.
HEALTH AND SAFETY
Caution:
Keep out of the reach of children and pets.
Wear suitable gloves.
Avoid contact with skin and eyes.
In case of eye contact ush with clean water seek medical attention.
In case of contact with the skin rinse with plenty of clean water.

Controls and Switches
Operating the machine
On heavy soiled carpets you can double the pressure of
the pump to 60 PSI by using the Hi / Lo switch (A)
To active the vacuum press ‘vacuum switch’ (B)
To activate the pump press ‘pump switch’ (C)
All the switches on the NHL machine have been designed to enable easy use and they are placed on the front of the
machine. These switches are to be operated by hand and NOT to be operated by foot.
A B C
Note. If machine not functioning correctly, see the Trouble-shooting guide Page 19
Correct way to use the machine
The NHL 15 oor-tool is provided with rear wheels
allowing the oor-tool to glide over the surface to be
cleaned (Fig 30).
Thus making the cleaning process less tiring and easier to
use.
Apply a slight downward pressure on the wand lifting the
oor-tool blade from the cleaning surface.
Move the oor-tool forward on the rear wheels (Fig 31).
Lift the wand allowing the oor-tool blade to come in
contact with the cleaning surface (Fig 32).
Operate the trigger (Fig 33), allowing the cleaning solution
to penetrate the carpet and slowly draw the oor-tool
rearward Vacuuming the cleaning solution up at the same
time (Fig 35).
Work backwards towards the exit door. (g 34)
For cleaning tips see page 2
Note. Do not over wet remember ‘What goes in, must come out again!.

Emptying the waste water
Cleaning the machine
You can empty the waste water tank by using the
dump hose attached to the rear of the machine
(Fig 38).
The waste water tank can also be removed and
carried using the handle to a suitable waste disposal
area and emptied (Fig 39).
Follow the national guide lines when disposing of
chemicals. (COSHH) see page 11
Caution.
The solution tube will be under pressure, switch off the pump and operate the trigger to
release the pressure in the system BEFORE removing the solution tube from the
machine.
Removing the wands and oor-tool
Unclip the solution tube from the machine see NOTE above.
Remove the wands, oor-tool (Fig 40)
and hose assembly from the machine (Fig 41).
Cleaning the tanks, lters and hoses.
