1.3 Transporting the machine
When transporting the machine ensure that all
components, tanks and removable parts are
securely fastened, and that the supply cord and
plug are not trailing. Detach hose and wand from
machine for ease of carriage.
Do not
lift or transport the machine whilst
containing liquid as this will add considerably to
the weight.

4
Take extreme care when moving the machine up
or down steps or stairs.
CAUTION
– Incorrect lifting techniques may
result in personal injury. We advise that the
manual handling regulations are followed.
1.4 Electrical connection
•
Before connecting the machine to the power
supply, check that your supply voltage
corresponds with that marked on the rating
label on the rear of the machine.
UK only
•
The supply cord is fitted with a non rewireable
plug containing a 13 amp fuse. Should the
fuse require replacement it must only be
replaced by a 13 amp fuse conforming to
BS1362, and the fuse cover must be refitted.
If the fuse cover is lost the plug must not be
used until the correct replacement cover is
fitted.
•
IMPORTANT - If the supply cord is damaged,
it must only be replaced by a special cord
available from the manufacturer or an
authorised service agent.
Should an extension cord be used, ensure cord
rating is adequate for the equipment. Do not use
extension cord in coiled condition as this could
result in overheating of the cord.

3 Preparing the machine
•
Fill the fresh water solution tank with water
and approved carpet cleaning chemical to a
maximum of 30 litres (Fig 1). Warm water
can be used to aid cleaning however this can
increase the risk of colour fastness and
carpets to shrink.
•
When inserting the power cord ensure that it
is quarter turned clockwise to ensure it is
locked in place.
NOTE: Ensure chemical is diluted correctly
according to instructions on container.
Fig 1
4 Operation
4.1 Priming and starting the machine
HM 55/100
•
Connect the solution and vacuum hoses to
the machine and the other end to either the
carpet or upholstery wand / tool.
•
Switch on the pump and one by one the
vacuum switches to begin operation.
HM 55/400
•
Connect the priming hose into the solution
outlet and the other end into the solution
tank.
•
Switch on the heater (if required) and pump
on to circulate the solution to remove air from
system. Let the heater heat up for
approximately 3 to 5 minutes.
NOTE: When the heater is on, the orange
indicator light on the switch panel will be lit.
•
Remove the prime hose and connect the
vacuum and solution hose to the machine
and the other end to either the carpet or
upholstery tool.
•
Adjust the pressure gauge to the required
level.
•
Switch the vacuum switches on one by one
to begin cleaning.
NOTE: use only one vacuum for more delicate
fabrics and upholstery.
4.2 Using the machine
•
Using the wand drag the head slowly over
the carpet whilst at the same time squeezing
the solution lever thus releasing the spray.
Repeat using overlapping strokes. There is
no need to apply downward pressure to the
wand as no improvement in performance is
obtained.
•
For best results, clean an area approx.
1 metre × 1 metre as above, and then go
over the same area with only the vacuum
running, and not releasing any solution.
Proceed to the next area.
•
The machine should be switched off
periodically to check there is no excess foam
in the recovery tank. If foam is present,
either add defoamer or if using an all in one
product, empty the recovery tank, rinse out
and continue, checking regularly for foam
build up.
•

•
When solution spray ceases the solution tank
is empty. Switch off the machine, empty the
recovery tank and refill the solution tank.
IMPORTANT
– Ensure recovery tank is emptied
whenever solution tank is filled.
IMPORTANT
– Do not run the pump motor when
the solution tank is empty, as this will damage the
motor.
IMPORTANT
– Should solution seep from the
drain hose cap, stop work immediately and drain
recovery tank.
4.3 Cleaning Carpet
Colour fastness -
Before using cleaning solution
or pre-spotter, test carpet for colour fastness on
an inconspicuous area. Apply solution to a small
piece of clean white material or tissue, and then
rub on carpet vigorously. Excessive amounts of
dye showing on the material indicate that the
colours are not fast, and the carpet should not be
wet cleaned. Please note temperature of
cleaning solution will also affect colour fastness.
•
Move furniture around to give a clear working
area. Cover bottoms of furniture legs where
necessary (aluminium cooking foil is ideal).
Pin up curtains and drapes.
•
Vacuum carpet thoroughly to remove any
residual dust or debris.
•
Areas of heavy carpet soiling can be removed
more easily if first treated with a concentrated
cleaning solution or pre-spotting solution.
•
Rate of cleaning will depend upon the
thickness of the carpet and the degree of dirt
in the area being cleaned.
•
Do not
over wet carpets. Carpets may shrink
if they are over-wet or not properly fixed
down.
4.4 Cleaning Stairs
•
CAUTION
– when cleaning on stairs exercise
great care to ensure that the machine is
stable and cannot overbalance, possibly
causing injury to either operator or third
party. Use the upholstery tool for cleaning in
place of the wand assembly.
4.5 Cleaning Upholstery
This is done in the same way as carpet cleaning
except using the upholstery tool in place of the
wand assembly. Cleaning is achieved using a
gentle dragging motion of the upholstery tool over
the material.
•
An inconspicuous area of the item to be
cleaned should always be tested for colour
fastness prior to cleaning. Should doubt exist
as to the suitability of the fabric for wet
cleaning, the chemical manufacturer should
be consulted for advice.
•
Loose cushions should be removed and
cleaned separately.
•
Do not
over-wet upholstery.
5 When Cleaning is Finished
5.1 Draining and Cleaning
•
When the recovery tank is full, empty by
using the drain hose at the rear of machine
(Fig 2). If a bucket is used to empty the
recovery tank, do not use the same bucket to
fill the solution tank as this can result in
putting dirt and grit into the solution line that
can block filters, orifices, and generally
degrade the solution line system (do not
reuse solution). Take care if using a bucket
to empty the machine. Stop flow before
bucket overflows. Empty bucket and repeat.
Fig 2
•
To empty solution tank, detach the wand
from the end of the vacuum hose and insert
the vacuum hose into the solution tank. Turn
the vacuum switches to the "on" position and
transfer solution to recovery tank and
dispose of as outlined above. Clean recovery
filter at this time.
5.2
Storage
•
After use check that water tanks are empty
and clean. Dry the machine as described
below.
•
We recommend running the vacuum motor
for approx. 2 minutes after use to eliminate
condensation within the machine body, thus
ensuring the motor and particularly the
bearings remain dry.
•
Store machine with recovery tank lid
removed and dump valve open (Fig 3).
Deodoriser may be left in the tank to prevent
unpleasant odours.
Fig 3

•
Wrap supply cord around handle ensuring
that plug is not trailing on the floor.
•
Store extractor indoors in a dry area.
•
Do not store in freezing temperatures.
5.3 Maintenance
WARNING - Before undertaking maintenance
operations or adjustments switch off machine
and unplug from the electricity supply.
To receive reliable service from this equipment,
regular daily maintenance is a requirement.
Cleaning carpet and upholstery is a very dirty
environment for any equipment.
The following recommendations are offered.
•
Keep the equipment clean, both inside and
out.
•
Supply cord
- Regularly inspect sheath, plug
and cord anchorage for damage or loose
connection.
•
Solution tank
– check filter is clean and
undamaged. A damaged filter must be
replaced or damage to pump head and spray
jet could occur.
•
Vacuum head
– Check and remove any
debris or lint build-up from the head.
•
Spray jet
– Check jet for blockage and full
spray pattern. Blow through jet to clean.
Do
not
use a pin, as this could damage the jet.
•
Lubricate brass quick disconnects and drain
valves with a quality lubricant such as WD-
40.
•
Flush solution systems after use with clear,
clean water. (A white vinegar solution may
also be used). This will counter-act hard
water and alkaline deposits and aid in
keeping orifices clean.
•
Do not allow fluid either in solution or waste
tank to sit overnight. The unit should be
emptied and cleaned daily.
•
Clean the filter in the solution tank, the filters
on the vacuum stack in vacuum tank and all
lint filters in the inlet or vacuum tanks daily.
•
Do not use the same bucket to fill solution
tank that is used to remove waste from
recovery tank.
•
When the unit is not in use, leave the
recovery tank lid open.
•
At the end of each day, run the vacuum for 2
minutes with lid open and filter off.
