when cleaning the plastic parts. Use care not to make
contact of the plastic parts with fluid like brake fluid,

Nozzle Cleansing
• Nozzles can get partially obstructed due to residues,
thus increasing pressure in the high-pressure gun. This
issue can be detected if there is constant pulsating when
pressing the trigger.
• To solve this issue turn off the Pressure Washer and
remove the nozzle as indicated in page 9.
• Using a paper clip, remove the obstruction from the
nozzle.
• Set the nozzle in the front end of the garden hose.
Open the faucet so that the water flow goes through the
nozzle in an inverse sense and releases the rest of dirt.
• Connect back the nozzle into the metal spear.
Air Filter Cleansing

good repair. Remember, a dirty filter can cause trouble
when the motor is started, loss of performance and
shorten the useful life of the motor.
• Uncover the air filter cover loosening and removing the
wing nut.

water.
• Press the filter lightly to remove the excessive water.
• Apply a thin layer of motor oil to the filter. Let it drip.
• Set the filter in place. Double-check it sits perfectly into

If necessary, adjust the gap by carefully bending the earth
connection electrode.

• Set the spark plug in place. Thread it and tighten by hand.
• Tighten with a wrench to compress the washer. If it is a
new spark plug, give it a 1/2 turn to press the washer in an
adequate manner. If using an old spark plug give it an 1/8
to 1/4 turn to compress the washer properly.
