Turn the water supply off
Note: make sure you depress the trigger on the gun to fully drain any residual water
left in the system. Failure to do so can result in damage due to corrosion or water
expansion when freezing.
1. Fill a suitable container with pressure washer detergent to mix as necessary. Do not
use washing up liquid as it contains salt.
2. Fit the blue / black nozzle to the end of the lance.
3. Connect the detergent tube to the pump and submerge the other end in the solution
4. Suction and mixing will occur as water ows through the pump. You may be required
to t the shorter of the supplied hoses in conjunction with the blue / black nozzle to
create the required pressure to draw detergent.
Note: a thick viscous detergent will not ow freely from
the detergent tank and the residue is likely to cause a
blockage in the system. After using the detergent facility
it should be ushed thoroughly with clean water to
remove any trace of detergent.
Using detergent

Nozzles
First ensure the machine is switched off before connecting / disconnecting any hoses
or attachments. Instead of attaching the hose from pump to tap, use the supplied hose
and lter set placing the lter end in the water supply.
It is advised that the water supply is on the same level as the washer. If you struggle to
get initial suction, remove the outlet hose from the pump and try drawing again - this
reduces the pressure on the pump making it easier to draw. Once owing, turn engine
off and reconnect outlet hose before re-starting.
Drawing from a barrel
0°Nozzle (Red) - This nozzle delivers a pinpoint stream of pressurized water and is
extremely powerful. It should only be directed at surfaces that can withstand high
pressure such as metal or concrete.
15° Nozzle (Yellow) - This nozzle delivers a powerful 15-degree spray pattern for
intense cleaning of small areas. This nozzle should only be used on areas and materials
that can withstand very high pressure.
25° Nozzle (Green) - This nozzle delivers a 25 degree spray pattern for intense
cleaning of larger areas. This nozzle should only be used on areas that can withstand
very high pressure.
40° Nozzle (White) - This nozzle delivers a 40-degree spray pattern and a less
powerful stream of water. This nozzle can cover a wide area and can be used for most
general cleaning jobs.
Detergent Nozzle (Blue/Black) - This nozzle is used to apply detergent and cleaning
solutions. This nozzle produces the weakest pressure of the three nozzles.

If the washer is not to be used or is to be stored for more than one month the following
storage procedure should be carried out:
1. Drain all the fuel from the fuel tank and the carburettor. Ensure that all fuel has been
removed.
2. Remove the spark plug and pour approximately one table spoon full of clean engine
oil into the spark plug hole.
3. With the ignition turned OFF, gently pull on the recoil starter handle several times.
4. Re-t the spark plug and continue to pull the recoil starter handle until the piston is
on the compression stroke (when resistance is felt) then stop pulling.
5. Store the pressure washer in a dry well ventilated place under a cover to prevent any
dust or debris from accumulating on the pressure washer.
If the pressure washer is not being used for more than three months or if there is any
danger of ice or frost where the unit is stored, especially during the winter months,
certain precautions must be taken to ensure no damage occurs to your washer or gun.
Follow the previous steps for storage but also ensure there is no water left inside the
unit. The pump may require insulated protection from freezing conditions. The gun
must be drained of uids to avoid water expansion as this will damage your gun.
No fuel should have been left in the unit. However if any fuel is present, ensure this
is removed from the tank and carburettor before refuelling with fresh fuel. Check the
deposit cup and empty if necessary.
Note: old fuel will not combust correctly and could damage your engine.
