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.

Fig.1
Model ELS140 .
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. 1.
Fig.2
Model ELS140R
The high pressure hose is fitted to a reel
at the back of the machine.
It is necessary to attach the handle to the
reel, as shown in Fig.3.
Connect the connecting hose to the inlet on
the reel and water outlet on the machine.
See parts diagram, p10.

OPERATION
Make certain the PUMP ON/OFF switch which is located on the front panel, is set
to the OFF position.
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, located in the base of the hand grip, in order to do so.
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.4
All Models
Screw the loose end of the high
pressure hose from the Lance, into the
high pressure outlet at the front of the
machine, shown at C Fig. 2.
Take care not to cross thread the fine
threads.
The low pressure water inlet, shown at
D, Fig. 2, 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 ti your water supply.
We recommend that you connect to
a supply of CLEAN WATER ONLY.

If you desire a fan spray, turn the nozzle fully anticlockwise - for a high pressure
pencil jet, turn it fully clockwise.

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.
WARNING
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.
ELS 140
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.5
ELS 150
As illustrated in Fig. 6, turn the grip for
high and low pressures....
Fig.6

IMPORTANT: The chemical injection
facility will ONLY operate at LOW
pressure.
If you intend to use the chemical
injection facility, fill the detergent tank
with the requisite detergent. The filler
cap is located directly beneath the
handle
Alternatively, provision is made so that
an external source of detergent may
be used. To do this, first disconnect the
hose from the reservoir to the pump,
at the pump connection shown at A.
fig. 4 and also at A in fig..6, and in its
place, connect the length of hose
CHEMICAL INJECTION FACILITY
supplied and lower it into a drum of detergent.
The amount of detergent that enters the system may be regulated by turning the
knob shown at B, fig. 6. The total movement of the knob is approx. 1/8 of a turn
from Max. to Min.
Max. provides a mixture strength of approx. 15:1...Min-approx. 1000:1.
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.
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.

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 front cover by unscrewing the three
securing screws, one at the top, centre (A fig. 7),
and one at either side at the bottom (B, fig. 7), to
reveal the motor.
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.
