designed to operate on 230VAC 1ph 50Hz. Connecting it to any other power
source may cause damage.
Connect the mains lead to a suitably fused 230V, 1 phase electrical supply via
a 16 Amp inductrial 3-pin connector (to BSEN 60309-1/2).
IMPORTANT: A domestic 13Amp plug MUST NOT be fitted to this appliance.
The electrical supply connection shall be made by a suitably qualified
electrician and comply with IEC 60364-1.
As the colours of the wires in the power cable of this product may not
correspond with the markings on the terminals of your plug, proceed as
follows.

BEFORE USE
CHECKING THE OIL
1. Remove the cover from the
pressure washer by removing the
securing thumbscrew from the
front and then the rear of the
cover then lifting it off.
2. Turn the oil filler cap anticlockwise
to remove it from the pump and
wipe the integral dipstick with a
clean cloth.
3. Insert the oil filler cap fully back
into place and then remove it
again.
4. If the oil is near the low mark on
the dipstick, add oil to the oil
reservoir.
• Do not overfill the oil reservoir.
• We recommend the use of
SAE30 oil.
• Do not mix grades of oil as this may effect the machine’s performance.
WARNING: TO CARRY OUT THIS CHECK, PLACE THE PRESSURE WASHER ON
LEVEL GROUND WHILE SWITCHED OFF.
WARNING: TAKE CARE NOT TO TOUCH ANY HOT PARTS WHEN CHECKING
THE OIL LEVEL.

CONNECTING THE MAINS WATER SUPPLY
The pressure washer must never be connected to the drinking water supply
without using a system separator (also known as a backflow preventer)
available from most hardware stores.
Always follow the regulations of your local water supplier.
1. Connect the water supply hose to
the inlet adaptor supplied with the
machine. A standard proprietary
hose is suitable.
2. Screw the inlet adaptor to the
water inlet as shown.
• It is recommended to use a
reinforced hose having an
inner diameter of at least 10
mm.
• The water supply must be able to deliver at least 15 l/min and have a
max inlet temperature of 65°C.
ASSEMBLING THE LANCE
1. Connect the spray lance to the gun assembly and tighten securely by
turning the locking ring.
CAUTION: WATER THAT HAS FLOWED THROUGH A SYSTEM SEPARATOR IS
CONSIDERED NON-DRINKABLE.

CONNECTING THE HIGH PRESSURE HOSE
1. Screw the high pressure hose onto
the gun assembly.
2. Use a spanner to tighten the
connector.
3. Screw the other end of the hose
on to the pressure washer outlet.
• Tighten the connector hand
tight only;- do not use a
spanner.
NOTE: Make sure the connections
are secure.
PARKING BRAKE
Before you operate your pressure
washer you should make sure that
the parking brake is engaged.
To do this press the brake flap shown
in the picture against the wheel to

OPERATION
1. The pressure washer should always be located on a firm level surface
where it is not exposed to extreme weather conditions such as strong wind,
freezing or rain.
2. It is recommended that where possible a partition be erected between the
wash area and the pressure washer to prevent accidental spraying of the
pressure washer. Moisture entering the machine may cause damage.

WARNING: DO NOT OPERATE THE PRESSURE WASHER INDOORS, OR IN
ENCLOSED AREAS WITHOUT ADEQUATE VENTILATION, OR IN AREAS
WHERE FLAMMABLE VAPOURS (PETROL, SOLVENTS ETC.) MAY BE PRESENT.
WARNING: IF THE PRESSURE WASHER IS TO BE USED IN AN ENCLOSED
AREA THE BURNER EXHAUST MUST BE VENTED TO THE OUTSIDE
ATMOSPHERE. THE USE OF A DRAFT REGULATOR IS RECOMMENDED. ALL
VENTING MUST BE IN ACCORDANCE WITH APPLICABLE LAWS AND LOCAL
ORDINANCES FOR SUCH INSTALLATIONS.

GETING STARTED
1. Ensure that the water supply is correctly connected and turned on.
2. Set the start switch (C) to ‘I’.
3. Release the trigger lock.
4. When using the machine for the
first time, let it run for a few
moments without the nozzle so
that any air bubbles or other
impurities are discharged.
5. Then re-fit the nozzle. pull the
trigger for a few seconds to
discharge any air contained in
the hose.
NOTE: When the trigger is pulled the
pressure of water will cause
the lance/gun assembly to
kick back suddenly.
6. The washer incorporates a total
stop system. When the trigger is
released the motor will stop. This
system is designed to protect the
motor and is also an important
safety feature.
USING THE WASHER AT DIFFERENT TEMPERATURES
1. Set the Temperature Selector (B) to the required temperature.
2. Set the start switch (C) to ‘I’ .
3. Set the Temperature Selector (B).
4. Ensuring that you have a firm footing and that you are also holding the gun
and spray lance firmly, pull the trigger on the gun to start water flow.
WARNING: FAILURE TO TURN ON THE WATER FULLY COULD CAUSE
DAMAGE TO THE PRESSURE WASHER.
WARNING: THE BURNER EXHAUST MUST BE VENTED TO THE OUTSIDE
ATMOSPHERE. ALL VENTING MUST BE IN ACCORDANCE WITH APPLICABLE
LAWS AND LOCAL ORDINANCES FOR SUCH INSTALLATIONS.

13
Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]
• The lance and gun will kick back when the trigger is first pulled.
• If heating of the water is required, the burner will light up to produce hot
water at the required temperature.
• The pressure washer is now ready for use.
• The machine should always be attended during hot wash operation.
5. Having used the pressure washer with hot water, set the temperature
selector to the minimum temperature and allow it to run with cold water for
a few moments before switching off.
6. At the end of the working session, switch off at the start switch (C) and by
pulling the trigger, to allow any residual pressure to be released.
USING DETERGENT
The detergent is applied by twisting
the cap on the lance as shown to
produce a wider spray patern with
lower pressure, and then pulling the
trigger on the gun.
When the nozzle is adjusted to a high
pressure and a narrow spray patern,
the detergent flow is halted.
When the nozzle is adjusted to high pressure and a narrow spray patern, the
detergent flow is halted.
WARNING: IF OPERATING THE MACHINE WITH DETERGENT INCLUDING
CLARKE CLEANING PRODUCTS, TAKE CARE NOT TO SET THE MACHINE TO
OPERATING TEMPERATURES OF GREATER THAN 100OC.
CAUTION: IF YOUR EYES COME INTO CONTACT WITH ANY CLEANING
FLUIDS, RINSE THEM IMMEDIATELY WITH PLENTY OF FRESH CLEAN WATER
AND SEEK MEDICAL ADVICE IF REQUIRED.

level floor while disconnected from the power and water supplies.
• Correct use and maintenance is necessary to guarantee the pressure
washer's reliability and best performance.
• The pressure washer requires regular checks to be carried out at the
following intervals. Please only use the correct spare parts as supplied by
your Clarke dealer.
DAILY (BEFORE EACH USE)
CHECK THE OIL LEVEL OF THE PUMP
1. See “Checking the oil” on page 7.
2. Check that the power cable is not damaged.
EVERY 2 WEEKS OR AFTER 50 HOURS WORKING
CLEAN THE WATER FILTER
1. Use a pair of square nosed pliers,
pull out the the inlet water filter
located in the water inlet and
clean out any foreign matter.

16
Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]
EVERY 3 MONTHS 0R AFTER 300 HOURS OF WORK
CLEANING/REPLACING THE FUEL FILTER
1. Remove the cover from the
pressure washer.
2. Rmove & replace the fuel filter
(A).
3. Clean or replace the detergent
filter (B).
If dirty, either clean with a jet of
compressed air or replace it with a
new filter.
SERVICING
These tasks must be carried out by skilled service personnel.
EVERY MONTH OR AFTER 100 HOURS OF OPERATION
CLEANING THE COMBUSTION HEAD & CHECKING THE ELECTRODES
It is recommended that the burner and electrodes be serviced yearly, or
as needed depending upon the pressure washers' usage.
Please contact the CLARKE International Service Dept.
LIMESCALE
Periodically the heating coil should be checked for limescale buildup,
dependant upon the hardness of the local water supply.
Please contact the CLARKE International Service Dept.
SOOT BUILD UP
Poor grades of fuel oil or inadequate combustion will cause heavy build
up of soot on the heating coil. This deposit will insulate the coil and

17
Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]
reduce its efficiency. It will also restrict air flow through the coil, further
aggravating the soot build up.
Contact your CLARKE dealer or CLARKE International Service Dept on:
020 8988 7400 if de-sooting is required.
DE-COMMISSIONING PRODUCT
Should the product become completely unserviceable and require disposal,
draw off the oil into an approved container and dispose of the product and
the oil according to local regulations.
Recycle unwanted materials instead of disposing of them as
waste. All tools, accessories and packaging should be sorted,
taken to a recycling centre and disposed of in a manner which is
compatible with the environment.
CONSUMABLES ETC
A range of suitable hoses, shampoo and traffic film remover are available
from your Clarke dealer.
