Many of my customers use these jetwash machines commercially. After years of experience dealing with their problems and queries I have compiled a simple user guide, including a handy troubleshooting section, to make using your pressure washer as hassle-free as possible. Remember – Always read and follow the manufacturer’s instructions!

Charles’ tips on using your pressure washer:

1.  Connect to a CLEAN supply of mains pressure water. Ensure that the filter mesh is in place (located behind the inlet water quick coupling fitting) Open the water supply tap fully (insufficient water supply will result in reduced performance, and can cause damage to the machine.)

2.  Unroll the mains cable completely, and connect it to a proper power supply point with a good connection (the use of inadequate extension leads is the most common cause of problems.) If you are using a good quality heavy-duty extension cable, it MUST be fully unrolled, and should ideally be as short as possible.

3.  We recommend the use of a STIHL high pressure hose extension instead of an electric extension lead.

4.  After using your pressure washer, switch off the mains supply and water supply, and pull the trigger to release water pressure from the machine.

5. Store in a frost protected place.

6. Don’t allow dirt to enter the water fittings.


Here are some common problems- I have listed the probable causes and how to go about solving them.

Pressure washer does not switch on:

1.   Blown fuse

2.  Mains power supply fault (Check socket with another power appliance)

The fuse blows:

1.  Overheating due to rolled up electric cable (fully extend extension cable, feel it for any warm places indicating a fault.) Unplug it first!

2.  Overheating due to inadequate extension lead or faulty electrical connection at plug top.

3.  Overheating due to damaged plug top not making proper connection

4.  Overloading due to pressure nozzle being partly blocked by dirt (try another nozzle, clean it by backflushing)

5.  Overheating due to constant start stop due to leaking o-ring seal, faulty valve (have it repaired) or pressure nozzle being partly blocked by dirt (try another nozzle, clean it by backflushing.)

Low pressure:

1.  Adjustable nozzle set to fan. (adjust nozzle to higher pressure setting)

2.  Inadequate water supply (rectify)

3. Blocked intake screen. (clean and refit screen)
