and cause the unit to pulsate while spraying . To clean
out the nozzle:
1 . Turn off and unplug unit .
2 . Turn off water supply . Relieve any pressure trapped
in the hose by squeezing trigger 2-3 times .
3 . Separate lance from gun .
4 . Rotate nozzle to the narrow stream setting . This
opens up the fan blades .
5 . Using included tip cleaner, or an unfolded paper
clip, insert wire into the nozzle hole and move back and
forth until debris is dislodged .
6 . Remove additional debris by back-flushing water
through the nozzle . To do this, place end of a garden
hose (with water running) to end of nozzle for 30-60
seconds (fig . 18) .
EXPLOITATION
When spraying water against a surface, maximum im-
pact is generated when the water strikes the surface
“head on .” However, this type of impact tends to cause
dirt particles to imbed in the surface, thereby prevent-
ing the desired cleaning action .
The optimum angle for spraying water against a clean-
ing surface if 45 degrees (fig . 19) .
Spraying water against a surface at this angle provides
for the most beneficial impact force combined with ef-
ficient removal of debris from the surface .
Another factor that determines the impact force of the
water is the distance from the spray nozzle to the clean-
ing surface . The impact force of the water is increased
as the nozzle is moved closer to the surface .
DETERGENTS
The use of detergents can dramatically reduce cleaning
time and assist in the removal of difficult stains . Some
detergents have been customized for pressure washer
use on specific cleaning tasks . These detergents are ap-
proximately as thick as water . The use of thicker deter-
gents, such as dish soap, will clog the chemical injection
system and prevent the application of the detergent .
The cleaning power of detergents comes from apply-
ing them to a surface and giving the chemicals time to
break down the dirt and grime . Detergents work best
when applied at low pressure .
The combination of chemical action and high pressure
rinsing is very effective . On vertical surfaces, apply the
detergent starting at the bottom and work your way
upward . This will prevent the detergent from sliding
down and causing streaks . High pressure rinsing should
also progress from the bottom to top . On particularly
tough stains, it may be necessary to use a brush in com-
bination with detergents and high pressure rinsing .
NOTE: Use only detergents formulated for
pressure washes .
WATER SUCKING FUNCTION
The Machine could connect to water supply tap, or suck
water from a bucket .
Take the suck hose out of bucket, hold the Nozzle on
Low pressure Postion at first . Keep the machine running
a few seconds to draw-out surplus water and air in the
machine . Put hose back to water, hold the Nozzle on
Low pressure Postion . Switch it to High pressure Posi-
tion after water flow a lot from Nozzle .
SERVICE & MAINTENANCE
WARNING!
Unplug the electric cable (power
source) prior to any maintenance or prepara-
tory storage operations .
Make sure that the machine is not live when carrying
out maintenance work on the motor .
To ensure good performance, check and clean the suc-
tion and detergent filters after every 50 hours of oper-
ation .
Long periods of disuse may lead to the formation of
lime scale deposits . Working through the hole on the
rear, RELEASE the motor using a screwdriver (for models
with this feature) .
Then remove the screwdriver and proceed with the re-
start operations .
Cleaning
Keep the ventilation slots of the machine clean to pre-
vent overheating of the engine . Clean the housing reg-
ularly with a soft cloth, preferably every time it is used .
Keep the air vents free from dust and dirt . Remove stub-
born dirt with a soft rag moistened in soapy water . Do
not use any solvents such as petrol, alcohol, ammonia,
etc . as such substances can damage the plastic parts .
Lubrication
The appliance does not need any extra lubrication .
Storage and transportation
Keep the high pressure washer in well-ventilated dry
premises with temperature not going below +5ºC . Op-
erate the cleaner with non-corrosive / non-toxic anti-
freeze before storing for the winter .
