v.1.1
Adjusting the Pressure
The pressure setting has been set and tested at the factory during manufacture and should not be adjusted by the user.
You can safely adjust the operating pressure using the pressure regulator, using different nozzles, adjusting the distance between the nozzle and
the cleaning surface.
Important:
For most effective cleaning keep the spray nozzle approximately 8 to 24 inches away from the cleaning surface. When cleaning tyres
do not bring the nozzle within 6 inches of the surface to avoid damage and potential injury.
Nozzle Selection
The pressure washer is equipped with four different nozzle types which are stored in a receptacle below the handle at the rear of the detergent
tank. The following table and illustrations below provide a quick guide to the type of nozzle selections available.
Nozzle
Description
0° Nozzle
High pressure cleaning (stone, metal etc.)
15° Nozzle
Mid pressure cleaning (stone, metal, wood etc.)
40° Nozzle
Wide washing. Low pressure, everyday use (wood plastics etc.)
Detergent Nozzle
Delicate materials. Chemical cleaning using approved cleaning
products. Seek advise before use if you are unsure which deter-
gents are safe to use with this equipment and your local environ-
ment.
Changing Nozzles
Warning do not attempt to change the nozzles while the appliance is running. Turn the washer
OFF
before changing
nozzles. To change the nozzle pull back the collar and insert the nozzle and release the collar so that it locks securely.
Twist and test that the nozzle is secure before turning the pressure washer back on and pressing the gun trigger (see
Fig.7
).
Cleaning Blocked & Dirty Nozzles
If the nozzle becomes blocked with dirt or debris the pressure will become
imbalanced and will place excessive strain on the pump.
If the nozzle is blocked, stop the washer and turn off the water supply.
Pull the trigger on the gun to relieve any latent water pressure. Disconnect
the lance from the gun. Remove the nozzle from the lance. Clean the
nozzle using the nozzle cleaning tool supplied and rinse with clean water.
Reassemble and reconnect to the power and water supply. Test the nozzle
on the high pressure setting (
Fig.8
).
