6.1.1. Check that the inlet filter is clean; pump delivery and pressure will be reduced if blocked. Never use the machine without a filter (which is fitted inside the inlet connector fig.1.9). Ensure that the water supply, high-pressure hose, and gun are correctly connected, and that air can circulate around the washer freely.
6.2.1. To prevent inadvertent operation of the unit, the safety catch in the base of the trigger should always be engaged when the gun is not in use (fig.5).
6.3.1. It is very important to bleed the gun before using the pressure washer. Squeeze the trigger BEFORE turning the electrical supply on.
This allows any air trapped inside the pressure washer and gun to be removed before using the unit. Continue holding the trigger for approximately one minute to allow any excess air out of the unit. Water will flow through the gun at low pressure during this procedure.
6.4.1. There are three levels of pressure settings (fig.4). Level 1 is the setting suitable for cleaning fences, cement terraces, etc. Level 2 setting is suitable for cleaning vehicles,  boats, motorcycles, etc. Level 3 setting is suitable for cleaning barbeque grills, garden tools, etc.
NOTE: The default level at start-up is Level 2.
6.5.1. Hold the spray gun firmly to counteract the recoil caused by the high pressure of the water. Before switching on, ensure that the lance is not directed at people, objects or animals prior to being directed at the object to be cleaned.
6.5.2. It is recommended that the trigger is depressed before switching on the unit before every use. This reduces the back pressure and amperage draw which prevents fuses blowing.SEALEY PW2400 170 BAR PRESSURE WASHER - fig 5

6.6.1. The fan nozzle can be adjusted from pencil point to fan jet by rotating the body of the nozzle (fig.3)
WARNING! The pencil point setting is very aggressive. It is recommended that for most cleaning applications, a 20° spray angle is used to avoid damage to the surface being sprayed.
