OPERATION AND USE
WARNING:
ENGINE OIL IS NOT PROVIDED WITH THIS MACHINE. PLEASE ENSURE THE ENGINE IS FILLED WITH CLEAN,
HIGH QUALITY OIL BEFORE USE.
-This engine features a low oil level shutdown, however it is important not to run the engine with a
high or low oil level as this may cause damage. To avoid this problem, check the oil level before
starting the engine.
-Check that the pump oil level is correct.
STARTING UP:
Water Supply Connection:
-CAUTION! It is important to use clean or filtered water for intake only. Ensure that the water intake
is sufficient to match the flow of the pump.
-Keep the pressure washer as close to the water supply as possible.
-Water can also been used from the main supply. To do this, simply connect a supply hose to the
water inlet of the unit and to the desired water supply. Turn on the water supply. Ensure that the
hose used is at least 13mm and that it is an reinforced hose pipe.
-Do not operate the appliance for more than 2 minutes whilst the spray gun is in the closed position
as this will over heat the pump. (N.B. All Evopower pressure washers are fitted with thermal relief
valves to prevent any instance of overheating, however it is good practice to switch the engine off
when not pressure washing.)
-Do not operate the pressure washer with a pulsing action. Pulsing is the repeated on and off
operation of the trigger.
-Water can also be used from an open container. To do this, unscrew the coupling part of the water
inlet. Next, screw the suction hose (with filter) onto the water connection of the unit. Hang the filter
up in the container and vent the unit before usage. Unscrew the high pressure line at the high
pressure outlet of the unit. Turn the unit on and let it run until there are no longer bubbles present
at the high pressure outlet. Turn the unit off again and screw on the high pressure hose again.
-If the above conditions are not followed correctly, serious damage can be cause to the machine.

-ADJUSTING THE SPRAY PATTERN (FIG 23)
Your Evopower Pressure Washer comes complete with five
colour-coded nozzles and a turbo nozzle, each giving a different
spray pattern. Each nozzle does as follows.
RED: 0⁰NOZZLE
This nozzle gives an extremely powerful pinpoint stream. It covers
only a small area and due to its power should only be used on
materials such as metal or concrete. DO NOT USE ON WOOD.
YELLOW: 15⁰ NOZZLE
This nozzle delivers a powerful spray pattern, making it ideal for
cleaning small areas. As with the red nozzle, this nozzle should only be
used on areas which can withstand this high pressure.
WHITE: 40⁰ NOZZLE
This nozzle gives a less powerful stream than the first two nozzles.
This means that it can cover a much larger area meaning that it can
be used for a wide range of cleaning jobs.
GREEN: 40⁰ NOZZLE
This nozzle gives a less powerful stream than the first two nozzles.
This means that it can cover a much larger area meaning that it can
be used for a wide range of cleaning jobs.
BLACK: LOW PRESSURE NOZZLE
This nozzle has the lowest pressure and is perfect for applying
chemicals or cleaning solutions.
TURBO NOZZLE (EPW185-70AR / EPW275-14AR)
This nozzle produces a spiral spray of water, and provides up to twice
the effective cleaning power.
NOTE:
It is vital to test a small area first when cleaning items such as paving slabs to
ensure that damage will not be caused. Connect the nozzle to the lance using
the quick release coupling. In order to connect a nozzle, slide the collar back
towards the gun and push the nozzle into the end of the lance. Release the
collar to lock the nozzle into position. To disconnect, slide the collar back in
the direction of the gun.

-USING THE DETERGENT FACILITY
We strongly recommend using a high quality pressure washer detergent OR a traffic film remover (TFR)
with this machine.
NOTE:
Please note that thick detergents may not flow freely from the tank and so may cause a blockage in the
flow system.
To avoid this problem from occurring, flush the detergent facility out with a generous amount of water
after use. In order to activate the detergent delivery, fit the black nozzle onto the lance and completely
submerge the end of the detergent pick up pipe in the container of detergent. If an extended high
pressure hose is used, the detergent function may not work.
-CLEARING A BLOCKAGE
A blockage may be the problem if the flow rate reduces splutters or becomes inconsistent. To solve,
release the trigger and switch the machine off. Next, squeeze the trigger to relieve any pressure and
carefully check the jet in the end of the lance for any blockage that may have occurred. If this is the case,
use a thin piece of wire to clean the nozzle.

PRE-OPERATION INSPECTION
CAUTION:
In relation to the engines performance, engine oil is a key
factor. Only use high quality, clean oil with no additives. Do not
use 2-stroke gasoline engine oil. Using unsuitable oil will
shorten the engines service life.
RECOMMENDED OIL: SAE15W40 (for pump and engine)
-Make sure the engine is on level ground. Check the oil level
by fir
stly removing and cleaning the dipstick. Reinsert the
dipstick into the oil filler. If the oil level is too low, fill to the
recommended mark.
CAUTION:
Running the pressure washer with an insufficient supply of
engine oil may cause serious damage to the engine.
-ENGINE OIL REPLACEMENT
Ensure the machine is located on a level surface and allow the
engine to warm up for several minutes. After this, turn the
engine off and remove the oil filler cap. Carefully place an oil
pan under the engine and completely drain the machine of oil
by removing the oil drain plug. Alternatively, the oil can be
sucked out of the oil filler neck using an oil suction device.
-Check that no damage has been caused to the oil drain plug,
gasket, oil filler cap and O-ring. If damage has been caused
replace immediately.
-Replace oil drain plug.
-Add engine oil to the top of the oil filler neck.
Rev 2

-FUEL AND FUEL TANK:
FUEL
Ensure that only fresh, clean unleaded petrol is used. This will decrease the chance of producing a
carbon deposit and will prolong the engines service life. Also, ensure that old or polluted fuel is
never used as this may cause damage to the engine, and make it difficult to start.
-CAUTION:
Fuel must be handled carefully as itcan cause extensive damage to plastic orpainted surfaces.
Before use, check the fuel level. Ifthe fuel level istoo low, refuel the tank. Remember not tofill
over the fuel filter shoulder. N.B Modern unleaded petrol has a short shelf life. Ifleft for more
than two months, itmay start todeteriorate.
-WARNING:
It isimportant toremember that petrol isanextremely flammable and potentially explosive fuel.
For this reason, refuel ina well ventilated area when the engine has been completely stopped. Do
not allow any flames orsparks near the refuelling area. Ensure that the fuel cap isfastened
securely after use. Any accidental spillages should be cleaned up immediately in a safe
manner. Keep out of the reach of children.
-FUEL TANK FILTER (FIG 26.)
The fuel tank filter should be removed and cleaned every 150 hours ofrunning time orevery
three months, whichever comes sooner. Todothis, remove the fuel tank filler cap and the filter
and clean the filter thoroughly.
-LOW ENGINE OILSHUT DOWN:
NOTE:
Once the oil level is too low, the engine low oil shutdown will stall the engine automatically to
avoid damage whilst the engine is still on. Insufficient oil will cause damage tothe engine. If the
engine oil level istoo low, the engine will not run.
Fig 26.
Rev 2

20
-AIR FILTER (FIG 27.)
The air filter should be removed, examined and cleaned
every 100 hours of running time or every month, whichever
comes sooner. The air filter should be cleaned with an
environmentally friendly water based degreasing agent. The
air filter should then be left the dry before replacing it back
into the machine and adding a few drops of engine oil,
squeezed into the foam filter. Do not run the pressure
washer without the air filter correctly fitted (Foam air filter
only).
- STORAGE
The following storage rules should be followed if the pressure washer will not be used or is to be
stored for more than one month.
Drain all fuel from both the fuel tank and carburettor. Next, remove the spark plug and pour in
around one tablespoon of clean engine oil into the spark plug hole. Make sure the ignition is
turned off, and then gently pull on the recoil starter cord several times. Replace the spark plug
and continue to pull the recoil starter cord until the piston is on the compression stroke then
stop pulling.
When storing the pressure washer, make sure you do so in a dry and well ventilated place under
cover.
-PREPARATION FOR WINTER AND LONG TERM STORAGE
Different preparation is required if the pressure washer is not going to be used for over
three months or if it is to be stored over the winter months where frost and cold weather is
likely. Mix a solution of automotive antifreeze as recommended on the packaging in order to
protect the pump unit. When the solution has completely drained out of the outlet seal with a
cork or other bung. Then continue to decant the antifreeze solution into the inlet until the
pump is full and then carefully seal the inlet.
When using the pressure washer for the first time after a lengthy time in storage, ensure that all
antifreeze is flushed thoroughly out of the pump, hose and lance. Small leaks may occur from
the pump when the pressure washer is first started, however these will disappear after a short
time.
