DANGER! Read and understand the complete User Manual before assembling or using
this equipment! Failure to comprehend and comply with these warnings, cautions, and
instructions for assembly and operation could result in serious injury or death.
DANGER! Do not permit children to operate this equipment at any time.
DANGER! Do not permit others that have not read and understood the complete User
Manual to operate this equipment. Operation of the equipment can be dangerous. It is the
sole responsibility of the operator to understand the assembly and safe operation of this
equipment.
Please refer to Section II • Safety in this User Manual for an extensive list of warnings and
precautions to follow prior to operating this equipment.
WATER SUPPLY
WATER SUPPLY FROM WATER MAIN
• Connect a water supply hose (not included) to the water inlet connection of the pressure
washer.
• Turn on the water supply and pull the trigger until the water is continually flowing out of
the nozzle.
WATER SUPPLY FROM A CONTAINER
• Unscrew the coupling part for the water inlet.
• Screw the suction hose with filter (not included) onto the water connection of the unit.
• Hang the filter in the container.
• Vent the unit before operation.
• Unscrew the high-pressure line at the high-pressure outlet of the unit.
• Switch on the unit and let it run until water is free of bubbles at the high-pressure outlet.
• Switch o the unit and screw on the high-pressure hose again
BEFORE SPRAYING
Pull the trigger to eliminate trapped air
and wait for a steady flow of water to
emerge from the spray nozzle.
NOTE: To prevent accidental operation,
the trigger is fitted with a locking
mechanism.
ENGLISH

20 | OPW480EV man.
USING THE DETERGENT
(FIG. 1) It is recommended to use good quality pressure washer
detergent for use with this pressure washer. Please follow the
instructions on the fluid container. Most automobile detergents
are a combination of a detergent and 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 filling the container. When using wash and wax combination
solutions we recommend that they are diluted before use. As a
general guide, we would recommend a dilution ratio of 50/50.
However a trial and error process would determine the ideal dilution ratio for a particular detergent.
NOTE: A thick, viscous detergent will not flow freely from the detergent container and the residue
from this can cause a blockage in the flow system. After using the detergent, the system should
be flushed thoroughly using ample amounts of water. To activate detergent delivery, fit the black
LOW PRESSURE nozzle to the end of the lance. Suction and mixing will occur automatically as the
water flows through the pump.
CLEARING BLOCKAGE
(FIG. 2) If at any time the flow rate stutters or shows inconsistency,
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 blockage is suspected, use some wire
to clean inside the nozzle.
