Step by step guide
Master: replace hose reel parts
Servicing our pressure washers are quite straight forward and could be done by most people by following the step-by-step instructions in this manual.
Please go trough the whole manual before starting work on your pressure washer to make sure you understand the procedure and that you have the necessary tools to complete the task.
Always unplug the pressure washer from both the mains power and the water outlet before starting the service.
Even though power and water is disconnected there may be pressurized water in the hose. Discharge this pressure by pulling the trigger on the gun.
Make sure your work area is clean and appropriate for the work you are about to do. There will usually be a small amount of water inside the pump and hose.
If you are doing a 10-year service, then be prepared to collect the used oil from the oil chamber. Please dispose of the oil in accordance with local law and regulations.
ISO 46 hydraulic oil can be substituted with similar non detergent oil of the same viscosity.
