✔✔
✔ When making a connection directly to the water mains supply you must ensure
✔✔
that it incorporates a device suitable to prevent liquids syphoning back from
the power washer into the mains pipework.
✔✔
✔ After the engine has been stopped and the water supply turned off, but before
✔✔
disconnecting any hose or accessory, ALWAYS release any residual pressure
in the system by operating the trigger.
✔✔
✔ ALWAYS keep the machine itself dry and well clear of water spray
✔✔
✔✔
✔ When not in use, ALWAYS disconnect from the water supply, and ensure the
✔✔
system is completely drained. Store in a cool dry location.
✔✔
✔ When using the chemical injection facility, use only the chemical cleaning agents
✔✔
(detergents), that are approved for power washers. CLARKE Traffic Film Remover or
CLARKE Wash and WAX (available from your dealer), is recommended.
FEATURES
These fully portable machines incorporate a variable pressure control, together with a fan
or jet spray, and may be used with or without a detergent. Although these machines were
designed to operate using a mains water supply, they will also work satisfactorily with a
supply which is under positive pressure, i.e. from an elevated water tank etc.
When using the mains water supply, you must ensure you comply
IMPORTANT:
with all local bye laws.

4.Carefully turn the chassis onto one side to access the
axle to enable wheel to be fitted. Slide wheel onto
axle as shown, ensuring the flat side is on the inside as
in Fig. 2 to allow the cap to be fitted.
Fig. 3
5.Place the wheel securing washer in the drift as shown,
ensuring the concave side faces outwards.
6.Position the washer centrally on the axle, gently
using a suitable hammer/mallet, drive the washer
onto the axle as in Fig. 4. Take care not to drive it
on too far, allow a slight sideways movement of
the wheel.
7.Repeat 4, 5 & 6 for other wheel.
8.Fit the wheel caps by lining up the securing lugs
on the inner flange and gently tap on by hand.
9.Turn the chassis over onto its wheels and feet.
10. Attach the motor, on its mounting plate to the
frame, using the nuts, bolts and washers provided.

12. Slide the upper tool holder onto the chassis above the
lower holder. Fit the handle by lowering onto chassis as
far as the locking pins, depress pins and lower further
until the pins click into position.
NOTE: Take care not to pinch fingers in the mechanism when
carrying out this action.
11. Fit the lower tool holder to the frame by locating the
holder lug into the smaller L/H slot on the bracket,
rotate the holder until the R/H lug locks into position.

OPERATION.
NOTE: Before connecting the garden hose, unscrew and remove the hose connector which
is located on the opposite side of the pump to the high pressure hose connector
Fig.8b, check that the water filter is in place and is not damaged.
1.Connect the garden hose to the water inlet (hand tight only).
2.Connect the other end of the garden hose to the mains water supply and turn ON.
3.Depress the gun trigger to clear any trapped air, keep depressed until a steady flow
of water emerges from the spray nozzle.
4.Refer to engine handbook on starting the engine.
Move the throttle control lever to the run position.
Fig. 9a
5.Slowly press the primer ball 3 times, waiting 3 seconds
between each press. In cold weather conditions, press
the ball 5 times.
Fig. 9

6.Pull the starter with a quick firm action. Allow the cord
to recoil fully into its housing whilst retaining a grip on
the handle. Repeat operation until the engine starts.
As soon as the engine starts, slowly move the throttle
lever back towards stop until the engine is running at a
reasonable tick over speed and not racing flat out.
Fig. 10
NOTE:
1.If there is any difficulty in starting the engine, get an
assistant to fully depress the gun trigger whilst you attempt
to start. This will relieve any load on the engine, making for an easier start.
2.Be aware that the pump delivers a considerable pressure. If the lance is set to high
pressure and the trigger is depressed, you will experience a kick back. Ensure you
are prepared for this, and hold the lance firmly. DO NOT allow children to hold or
operate the lance.
When ready, pull the trigger, taking into account the notes above, and water at ptressure
will be ejected. Note that it may be
Fig. 11
necessary to unlock the trigger by pushing
in the yellow button,above the trigger. This
should be set to ensure the gun is not
‘fired’ accidentally.
The spray pattern can be adjusted to
AB
CD
create various patterns and pressures, see
Fig .11. Pull nozzle out (A) for high pressure
and in (B) for low.
Rotate the nozzle to vary the spray from
a fan to a straight jet.
Rotate the nozzle anticlockwise (C) for fan
pattern and clockwise (D) for a straight jet.
CHEMICAL CLEANING AGENTS
To improve cleaning qualities, chemical cleaning agents (detergents) may be injected
into the low pressure spray. This is particularly useful for washing cars, greasy engine parts,
oil spots on concrete etc.
To inject a detergent, insert the clear plastic hose into the detergent container, ensuring it is
completely submerged, also check the other end is securely attached to the pump shown
in Fig. 8b.
N
OTE: Use ONLY detergents 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, as well as other cleaning tasks.
When detergent injection is required, adjust the nozzle to the low pressure setting, the
detergent will automatically be drawn into the water supply when sprayed.
Spray the detergent on to the vehicle, patio etc., and allow it to work itself into the grime.
To rinse, set the lance to its’ high pressure setting, and blast off the dirt.
After cleaning, suspend the detergent hose in a container of clean water. Set the lance to
low pressure with the engine running and the mains water supply ‘on’. Depress the trigger
of the lance, and thoroughly flush out the system.

MAINTENANCE
Very little regular maintenance is required, other than general cleaning on the outside of
the machine. Wipe over with a clean dampened soft cloth, use a mild household detergent
if necessary. Never use harmful chemicals.
If detergents have been used in the washer, it is important to flush the system with clean
water for a few minutes after use.
If there is a danger of freezing, anti freeze should be mixed with the flush water, or the
system must be completely drained.
Storage
Store in an upright position, completely drained of water, in a dry frost free location.
Engine
Refer to the engine handbook, and service accordingly.
NOTE: Engine oil should be checked before each use.
Pump
Change the oil after the first 50 hours of service, and every 500 hours thereafter.
DO NOT attempt to carry out any mechanical repairs yourself. Please contact your CLARKE
dealer for Service and repairs. If the pump is ever dismantled for servicing and/or repair,
remember to top up with 15w/40 non synthetic oil (100ml).
Periodically unscrew and remove the hose connector from the pump to expose the suction
filter, carefully remove filter inspect for damage and signs of wear etc, clean filter by holding
under the tap and allow the running water to flush out any impediment, DO NOT use tools
to clean the filter or damage will occur. When clean refit to the pump body followed by the
hose connector.
