2. Connect water.
3. Make sure no water is leaking from the inside or anywhere else on the pressure washer.
4. Pull the trigger and let the water flow until there is no more air coming out.
5. Connect the power cord.
6. Turn on the pressure washer.
7. Pull the trigger and let water run for a minute before connecting a nozzle.

Water is leaking from the inside

• Disconnect the power and open the pressure washer to locate the leak. Take necessary action to remedy any leaks.

Motor runs and won't stop when you release the trigger

• This is most likely due to an improper seating of the switch box on the start/stop valve.
• Open the machine and check that the switch box is correctly seated.

The pressure washer won't turn on

• Check that the power cable is connected.•Check that the circuit breaker has not been tripped.
• Check that the fuse in the power plug is intact (UK models only).
• Open the machine and check that all the internal cabling is connected.

Poor performance/pressure

• Improper assembly or dirt/debris in the pump. Check that the pump and especially the main valve for foreign objects/debris. Make sure that the spring in the main valve is correctly seated and working as intended.
