Note: Be careful when using the red nozzle (0º) to avoid any injury. Only the black nozzle is a low-pres-
sure foam nozzle for spraying detergent, and the other nozzles are high-pressure nozzles that do not
generate foam.

's better to use liquid detergent. Do not put any solid cleaner into the detergent tank avoiding the filter
blockage. If you want to use the solid cleaner, please water down the solid cleaner thinning it first, then
pour it into the detergent tank. Besides, if you hope to clean the car, we recommend you choose the car

Operation Cautions
Maintenance
English
When the first time using the pressure washer, there may exist some air in the spray gun and the high
pressure hose, so the pressure would not be on right away, it is normal. We recommend,
please long press the spray gun trigger for about 15 to 30 seconds after starting up the machine, to squeeze
out the air until the water is coming out, then install the spray wand. (To better protect the machine, this
step should also be done when the cleaning job is finished.)
I.Before Use :
Please note to release the pressure inside the machine after each use. The purpose for doing this is to drain
out of extra air and water inside, reset the overflow valve exactly, and make the disassembly easier.
Especially in the winter, if the pressure is not to be released timely after use, the pressure washer will
freeze, and fail to work. ( This steps is also required when there is no water coming out after starting the
machine. But if no water comes out after 2 minutes of starting the machine, please turn off the power
switch, to avoid any damage to the motor. )

※ Remove the water inlet adapter, and pull out the filter and rinse with water.
※ Disassemble the high pressure hose, spray gun and spray wand.
※ Store the power cord, high pressure hose, spray wand with gun and other accessories.
※ Please properly store the pressure washer, and do not put it outdoors during the winter if there is some
residual moisture water in the device has not been drained out.
※ Please pull out the filter and rinse with water before or after a long-term storage. Use needle to clean
the residue if necessary.
