15O NOZZLE - YELLOW

This nozzle delivers a powerful 15o
spray pattern for intense cleaning of
small areas. This nozzle should only
be used on areas and materials that
can withstand high pressure.

25O NOZZLE - GREEN

This nozzle delivers a 25o spray
pattern for intense cleaning of larger
areas. This nozzle should only be
used on areas and materials that
can withstand pressure from this
nozzle.

40O NOZZLE - WHITE

This nozzle delivers a 40o spray
pattern and a less powerful stream
of water. This nozzle can cover a

MAINTENANCE

GENERAL RECOMMENDATIONS

Regular maintenance will improve the performance and extend the life of the pressure
washer.

The pressure washer’s warranty does not cover items that have been subjected to
operator abuse or negligence. To receive full value from the warranty, the operator
must maintain the pressure washer as instructed in this manual and in the engine
manual, including correct storage as detailed in the storage section of this manual.

NOTE: Should you have any questions about replacing components on the pressure

washer, please contact the CLARKE service department.

• Some adjustments will need to be made periodically to properly maintain your

pressure washer. Check the spray gun and extension lance assembly for wear.

• All maintenance in this manual and the engine operator’s manual should be

made at least once each season.

• Once a year you should clean or replace the spark plug and clean or replace

the air filter. A new spark plug and clean air filter will assure proper fuel-air
mixture and help your engine run better and last longer. Please refer to the
engine operators manual for more details.

PRESSURE WASHER MAINTENANCE

CLEAN DEBRIS

Daily or before use, clean accumulated debris from the cleaning system. Keep the
linkage, spring and controls clean. Keep the area around and behind the muffler free
from any combustible debris. Inspect cooling air slots and openings on the pressure
washer. These openings must be kept clean and unobstructed.

• Use a damp cloth to wipe exterior surfaces clean.

• Use a soft bristle brush to loosen caked on dirt, oil, etc.

• Use a vacuum cleaner to pick up loose dirt and debris.

• NEVER use the pressure washer to clean itself.

CHECK AND CLEAN THE INLET SCREEN

Examine the screen on the pump water inlet (see item 18 on pages 6/7). Clean it if
the screen is clogged or replace it if the screen is damaged.

CHECK HIGH PRESSURE HOSE

The high pressure hose can develop leaks from wear, kinking or abuse. Inspect the
hose each time before using it. Check for cuts, leaks, abrasions or bulging of the

24

Parts & Service: 020 8988 7400 / E-mail: [email protected] or [email protected]

cover, damage or movement of couplings. If any of these conditions exist, replace the
hose immediately.

WARNING: NEVER REPAIR THE HIGH PRESSURE HOSE, ALWAYS
REPLACE IT. REPLACEMENT HOSE RATING MUST EXCEED THE
MAXIMUM PRESSURE RATING OF THE WASHER.

CHECK DETERGENT SYPHONING TUBE

Examine the filter on the detergent tube and clean if clogged. The tube should fit
tightly on the ridged fitting (see item 16 on pages 6/7). Examine the tube for leaks or
tears. Replace the filter or tube if either is damaged.

CHECK GUN

Examine the hose connection to the spray gun and make sure it is secure, and make
sure the safety latch is present and working correctly. Replace the spray gun
immediately if the safety latch is damaged or not working.

CHECK SPRAY LANCE

Occasionally, the spray lance can become clogged with foreign materials such as dirt.
When this happens, excessive pressure can develop. Whenever the pressure nozzle
becomes partially clogged the pump pressure will pulsate. If this happens, it should
be immediately cleaned.

NOZZLE MAINTENANCE

A pulsing sensation felt while squeezing the spray gun trigger may be caused by
excessive pump pressure. The principal cause of excessive pump pressure is a spray
tip clogged or restricted with foreign materials, such as dirt, etc. To correct the
problem, immediately clean the spray tip following these instructions.

1. Shut off the engine and turn off the water supply.

2. ALWAYS point the spray gun in a safe direction; squeeze the trigger to release
retained high water pressure.

3. Remove the spray nozzle from the end of the nozzle extension (see page 22).

4. Use the nozzle pin to free any foreign material clogging or restricting the spray tip.

5. Remove the lance from the spray gun.

6. Using a garden hose, remove additional debris by back flushing water through the
lance.

7. Reinstall the nozzle onto the lance.

8. Reconnect the lance top the spray gun.

9. Make sure the garden hose is connected to the water inlet.

10. Check that the high pressure hose is connected to the spray gun and pump.

25

Parts & Service: 020 8988 7400 / E-mail: [email protected] or [email protected]

11. Turn on water supply.

12. Start the engine.

13. Test pressure washer by operating with each quick connect spray nozzle.

PUMP OIL MAINTENANCE

CHANGING PUMP OIL

Change the pump oil after the first 25 hours of operation and then every 50 hours or
3 months, whichever occurs first.

NOTE: When changing the pump oil, use only high quality SAE10W30 oil. Use no

special additives.

CHANGING PUMP OIL AS FOLLOWS

1. Clean area around the oil drain plug
at the bottom of the pump.

2. Remove oil drain plug. Drain oil
completely into an approved
container.

3. When oil has completely drained,
reinstall the oil drain plug and

4. Clean the area around the pump oil
breather plug/dipstick. Remove the
dipstick and fill the pump with the
recommended oil.

5. Reinstall the pump oil dipstick.

6. Wipe up any spilled oil.

PUMP OIL CAPACITY AND TYPE

1. The oil capacity is 150ml

2. Below 40oF (4oC) the use of SAE30 will result in difficult starting. Above 80oF
(27oC) the use of 10W30 may cause increased oil consumption. Check oil level

more frequently.

ENGINE MAINTENANCE

Consult the engine operator manual for more information.

STORAGE

LONG TERM STORAGE

Petrol fuel can become stale when stored over 30 days. Stale fuel causes acid and
gum deposits to form in the fuel system or crucial carburetor parts. To keep fuel
fresh, add a fuel stabilizer liquid additive to the fuel. The fuel stabilizer is available at
most auto part stores.

Draining the petrol is unnecessary if the fuel stabilizer is used according to the
instructions that come with it.

Run the engine for a minimum of two minutes after the stabilizer has been added, to
allow it to circulate throughout the engine. The engine and fuel can be stored up to
24 months.

TO PROTECT AGAINST RUST FORMATION DURING STORAGE

OIL THE CYLINDER BORE

1. Remove the spark plug and pour approximately 1/2oz (15ml) of clean engine oil
into the cylinder.

2. Reinstall the spark plug and pull the starter handle slowly to distribute the oil. DO
NOT start the engine at this time.

3. Slowly pull the recoil starter 2 or 3 times to distribute and coat the cylinder bore
with oil.

STORAGE OF PRESSURE PUMP

1. Drain all the water from the high pressure hose, coil it and store it in the cradle of
the pressure washer handle.

2. Drain all the water from the spray gun and lance by holding the spray gun in a
vertical position with the nozzle pointed downwards. Squeeze the trigger to
remove fluids from the spray gun and lance. Store the gun and lance in the cradle
on the side of the washer.

3. Store the detergent hose, high pressure hose and spray gun so they are protected
from damage, such as being run over.

OTHER STORAGE TIPS

1. DO NOT store petrol from one season to another unless its been treated with a
fuel stabilizer.

2. Replace fuel container, if metal, and it begins to rust. Rust, dirt and debris can
contaminate the fuel supply and components resulting in poor performance and/
or internal damage to the engine.

3. Cover the pressure washer with a suitable cover that does not retain moisture
such as a plastic or plastic coated tarpaulin.

4. Let the pressure washer cool before covering it.

5. Store the pressure washer in a clean and dry area.

6. DO NOT let the pressure washer freeze.

RECOMMENDATION

It is recommended that you follow these steps to protect the internal seals of the
pressure washer when storing the unit for more than 30 days and/or when freezing
temperatures are expected.

1. Obtain a funnel, 6oz (175ml) of Recreational Vehicle (RV) antifreeze (ethanol and
propylene glycol) and approximately 36 inches of garden hose with a male hose

connector on one end.

WARNING: USE ONLY RV ANTIFREEZE (ETHANOL AND PROPYLENE
GLYCOL). ANY OTHER TYPE OF ANTIFREEZE IS CORROSIVE AND
CAN DAMAGE THE PRESSURE PUMP

2. Disconnect the spark plug. Ensure the cap cannot touch any metal on the
pressure washer.

3. Connect the 36 inch length of garden hose to the water inlet of the pressure pump
and place the funnel at the other end.

4. Add the RV antifreeze to the funnel and hose.

5. Pull the engine starter handle slowly several times until the antifreeze comes out
of the pressure hose connection of the pump.

6. Remove the hose from the water inlet of the pump.

7. Reconnect the spark plug.
