Ongoing Maintenance

Connections
The connections on the pressure washer hoses, gun and gun should be cleaned regularly and
lubricated with the manufacturer's recommended grease to prevent leakage and damage to the
0 Rings.
Nozzle
Clogging of the nozzle will cause the pump pressure to be too high. If the nozzle is clogged,
clean it immediately.
A nozzle clean must only be carried out when the nozzle is disconnected from the gun or
personal injury could occur.
1. Turn off the pressure washer.
2. Separate the nozzle from the gun.
3. Clear the nozzle with the included cleaning wire or use a small wire such as a paper clip.
4. Flush the nozzle backwards with water.
5. Reconnect the nozzle to the gun.
Restart the pressure washer and depress the trigger on the gun. If the nozzle is still partially
blocked or plugged, repeat above instructions.
If the previous procedure does not clear the nozzle, replace it with a new one.

Water Screen

This pressure washer is equipped with a water inlet screen to protect the pump. If the screen is
not kept clean, it will restrict the flow of water to the pressure washer and may cause damage
to the pump.
• The screen is fragile so be careful when cleaning or removing it. Any foreign particles
entering the pump may damage it.
• Do not operate the pressure washer without the screen in place.
• Remove the screen and back-flush to remove impurities from the screen.
• Replace immediately after cleaning.
