WARNING: THIS MACHINE MUST BE EARTHED.
This product is provided with a standard 13 amp, 230 volt (50Hz). BS 1363 plug, for
connection to a standard, domestic electrical supply. Should the plug need
changing at any time, ensure that a plug of identical specification is used.
IMPORTANT: The wires in the mains lead should be wired up in accordance with
the following colour code:
Green & Yellow - Earth
Blue - Neutral
Brown - Live
As the colours of the wires in the mains lead may not correspond with the coloured
markings identifying the terminals in your plug, proceed as follows:
• Connect the GREEN & YELLOW cord to terminal marked with a letter “E” or
Earth symbol “ ”
• Connect BROWN cord to plug terminal marked letter “L”
• Connect BLUE cord to plug terminal marked letter “N”
We recommend that this machine is connected to the mains supply through a
Residual Current Device (RCD).
FUSE RATING
The fuse in the plug for this appliance must be rated at 13 amps
IMPORTANT:
If this appliance is fitted with a plug which is moulded onto the electric cable (i.e
non-rewirable):
1. The plug must be thrown away if it is cut from the electric cable. There is a
danger of electric shock if it is subsequently inserted into a socket outlet.
2. Never use the plug without the fuse cover fitted.
3. Should you wish to replace a detachable fuse carrier, ensure that the correct
replacement is used (as indicated by marking or colour code).
4. Replacement fuse covers can be obtained from your local dealer or most
electrical stockists.
EXTENSION CABLES
If an extension cable is used, always ensure it is fully unwound. When used outdoors,
ensure the extension cable is specifically designed for outdoor use.
The maximum extension length is 25 metres. Ensure that the wire sizes in the cable
are at least 2.5mm2 in cross section. As a general rule, the extension cable must
be thicker than the cable supplied with the washer.
IF IN DOUBT, CONSULT A QUALIFIED ELECTRICIAN...Do not attempt any repairs yourself.

ASSEMBLY AND PREPARATION
The machine is supplied fully assembled except as detailed below.
Model ELS160R
6
Model ELS145 &145R
Fig.2
Fig.4
The lance is in two sections,
the high pressure hose being
integral with the lance
handle and trigger assembly.
Assemble by slotting the
spigot end of the lance into
the handle assembly. Push in
firmly and twist to lock it in
position as shown in Fig. 2.
The Lance is also in two sections,
and assembled by screwing the two
halves together as shown in Fig. 3.
The high pressure hose is screwed
to the adapter, just forward of the
trigger assembly
Fig.3
Model ELS145
Screw the loose end of the high pressure hose
from the Lance, into the high pressure outlet at
the front of the machine, shown in Fig. 4.
Models ELS145R &160R
The hoses to the 145R and 160R are attached to
the Reel
Model 160R requires the hose to be screwed into
the lance - just forward of the trigger assembly.
Take care not to cross thread the fine threads.
Attach the cable and hose storage brackets by sliding
them into place on either side of the handle assembly,
as shown in Fig.1.
Fig.1

OPERATION
Make certain the PUMP ON/OFF switch which is located on the front panel, is set
to the OFF position - marked ‘O’.
ELS145 ELS145R & ELS160R
ALL Models
The low pressure water inlet, shown in Fig. 3, carries a 3/4” BSP thread.
A 3/4” BSP adapter with a 1/2” hose connector is provided, so that a suitable
hose (not supplied), may be attached. You may use a either a worm drive clip
(not supplied), or a snap-on type connector, commonly available from most
hardware or DIY stores, to attach the hose, the other end of which should be
connected to your water supply.
We recommend that you connect to a supply of CLEAN WATER ONLY.
Connect the plug to the mains supply preferably
via a Residual Current Device.
Turn the water tap fully on.
When starting, you should always adopt the
following procedure:
1. In order to ease the starting process, and to
prevent the possibility of blown fuses, pull the
trigger on the lance - it may be necessary to
release the safety latch, please see Fig. 6.
Fig.5
Fig. 6

If you desire a fan spray, turn the nozzle fully anticlockwise - for a high pressure
pencil jet, turn it fully clockwise.
8
In the event that you switch the machine OFF, but intend to continue with its use
after a few minutes or so, DO NOT depress the trigger, but set the safety latch to
prevent it from being accidentally pulled. This will ease and assist the subsequent
restarting of the motor as pressures will remain equalised on either side of the
pump, thereby reducing the load on the motor when restarting.
NEVER attempt to run the machine with water supply disconnected or turned off.
It is recommended that whenever possible, a screen or partition be erected
between the washer and the wash area, to prevent accidental spraying of the
machine. Any moisture entering the machine could cause serious damage.
ELS 145 & 145R
Water pressure is regulated by turning the adjuster at the nozzle end of the lance,
(as shown by the arrows on the ferrule), ANTICLOCKWISE to INCREASE pressure
and CLOCKWISE to DECREASE, (looking from the handle end).
Fig.7
ELS 160R
As illustrated in Fig. 8, pull the nozzle IN for high pressure and OUT for low pressure.
Additionally, turn the nozzle, as indicated, to change from jet to fan spray.
2. Hold the trigger in that position whilst switching the pump ON, and allow the
pump to run for a few moments to develop full pressure
3. You may release the trigger once full pressure is developed. In doing so the
pump will stop, and will start again as soon as the trigger is pressed once more.
NOTE: For the reasons given above, it is recommended that you ALWAYS set the
jet to its LOW PRESSURE setting before switching ON. This is achieved as follows:
Fig.8

IMPORTANT: The chemical injection facility will ONLY operate at LOW pressure.
CHEMICAL INJECTION FACILITY
9
Fig.9
CAUTION
Ensure the operator is aware that when the trigger is pulled, water at high
pressure can cause the lance to kick - it should therefore be held firmly.
In addition, care must be taken to ensure that the nozzle is NOT aimed at
an area where the water jet will cause damage, i.e. away from people,
animals, windows - greenhouses etc., and be aware that splash back
could also cause damage if the jet is trained on a nearby wall etc.
If you intend to use the chemical injection facility,
fill the detergent tanks at thr rear of the unit, shown
in Fig.9, with the requisite detergent.
The amount of detergent that enters the system
may be regulated by turning the knob on the front
of the unit shown in Fig. 10.
Note that two tanks are provided so that a
detergent/cleaner may be used in one and a wax/
shampoo in the other, for example.
By turning the regulator knob to the left - the medium
in the left tank (looking from the front) will be used, and
turning to the right-will use the right tank
Max. provides a mixture strength of approx.
15:1...Min-approx. 1000:1.
SHUTTING DOWN THE MACHINE
If the chemical injection facility has been used, turn the pressure adjuster on the
end of the lance to HIGH pressure, and allow the pump to run for a minute or so
until the water being ejected is foam free, then switch OFF the pump.
Disconnect from the mains electrical supply, and turn OFF the water supply -
disconnect where appropriate.
IMPORTANT:
ALWAYS operate the lance trigger once more to ensure there is no pressure in the
high pressure hose. NEVER disconnect the high pressure hose without first pulling
the trigger.
Fig.10
Use ONLY those detergents specifically designed for use
with Power Washers. We recommend the use of CLARKE
Traffic Film Remover, which is a powerful low foaming
agent for car cleaning, patio cleaning etc., or CLARKE
Wash & Wax, both available from your CLARKE dealer.
IMPORTANT: Ensure you read and comply with the
manufacturers instructions regarding the use of chemical
detergents.

WARNING:
Ensure the plug is removed from the socket before carrying out any
adjustment, servicing or maintenance.
AFTER EACH USE
When using chemical detergents, always ensure the system is thoroughly flushed
out after use as described above.
Ensure the hoses and power cable are coiled and properly stowed. DO NOT allow
them to be left casually, in a heap. This invites damage and will cause rapid
deterioration.
MAINTENANCE
STORAGE
Store the Washer in a vertical position,
preferably under cover, protected from
the elements.
If there is a danger of freezing, the pump
should be filled with antifreeze by inserting
the inlet and outlet hoses into a bucket of
antifreeze as shown in fig. 7.
Start the machine and allow the antifreeze
to circulate. After a short time stop the
machine using the procedure outlined on
page 9, and store the machine with the
antifreeze still within the pump body.
NOTE:
If you experience difficulty in starting the motor following a long period of storage, it is possible that
the seals within the pump have dried out and are gripping the pistons. This problem may be
alleviated by storing the machine with antifreeze within the pump body, as described above.
If the seals are stuck however, disconnect the machine from the electrical and water
supply’s, and proceed to free them as follows:
Fig.7
Remove the lower rear cover by unscrewing the
four securing screws, to reveal the motor cover.
On the top of the motor is a circular plastic grill,
covering the motors’ fan. In its’ centre is a hole,
through which can be seen the head of a hex.
socket head screw.
Insert a hex. wrench (not supplied), through the
hole, into the screw head, as shown in Fig.8, and
turn the motor a turn or two to free it. It should
now be possible to start in the normal way.
