OPERATION AND USE
ADJUSTING THE SPRAY PATTERN (Fig.26)
You have the choice of 4 different colour coded nozzles giving you different
spray patterns to choose from:
0° nozzle (Red):
This nozzle delivers a pinpoint stream and is extremely powerful.
It covers a very small area of cleaning. This nozzle
should only be used on surface that can withstand this high pressure such as
metal or concrete. Do not use on wood.
15° nozzle (Yellow):
This nozzle delivers a powerful 5 degree spray pattern for intense cleaning of
small areas. This nozzle should only be used on areas that can withstand the
high pressure from this nozzle.
40° nozzle (White):
This nozzle delivers a 40 degree spray pattern and a less powerful stream of
water. It covers a wide area of cleaning. This nozzle should be used for most
general cleaning jobs.
Low pressure nozzle (Black):
This nozzle is used to apply chemicals or cleaning solutions. It has the least
power stream.
USING THE DETERGENT FACILITY (Fig. 27)
Fill a suitable container with pressure water detergent. Do not use washing
up liquid as it contains salt. We recommend the use of good quality
pressure washer detergent for use with this pressure washer. Please follow
the instructions on the container.
Most automobile detergents are a combination of a detergent and a wax
solution.
The viscosity (thickness) of the detergent will increase in cold weather. It
is recommended that this type of detergent is diluted with water before
llingthecontainer.Whenusingcombinationwashandwaxsolutionswe
recommend that they are diluted before use. As a general guide we would
recommend a dilution rate of 50/50. However a trial and error process
would determine the ideal dilution rate for a particular detergent.
NOTES:
Athickviscousdetergentwouldnotowfreelyfromthedetergenttankand
theresiduewouldcauseablockageowsystem.
After using the detergent facility it should be ushed thoroughly using
copious amount of water.
To activate detergent delivery, t the Black LOW PRESSURE nozzle to
the and of the lance. Submerge the and of the detergent pick up pipe into
your container of pressure water detergent. Suction and mixing will occur
automaticallyasthewaterowsthoughthepump.
CLEARING A BLOCKAGE (Fig. 28)
Ifat any time the ow rate stutters oris inconsistent, release the trigger
and switch “OFF” the machine. Squeeze the trigger to relieve any pressure
and check the jet in the end of the lance for any blockage. If a blockage is
suspected use some wire to clean the inside of the nozzle.

NOTE:
Before using the pressure washer to clean patio paving slabs itisadvisabletotestasmallarearst,somepavingslabsaremanufactured
from inferior materials and the use of a pressure washer could damage the surface.
