• Start the engine, referring to the relevant operating and maintenance manual.

• Open the water supply tap, if any.

• Press the spray gun lever (33) checking that the nozzle spray is uniform and there are no drips.

• If necessary regulate the pressure by way of the pressure regulating knob (17) (not for FDX2 10/150).

Turn it clockwise to increase pressure, anticlockwise to reduce it. You can see the pressure on the

pressure indicator (18).

• It is also possible to adjust the head (48) jet angle of the FDX2 10/150 model from fan to concentrated

(see Fig. 7).

CAUTION

• Before expecting maximum performance of the high pressure cleaner it is good practice to warm

the engine up for a couple of minutes.

The recommended detergents are more than 90% biodegradable. On how to use the detergent please

refer to the instructions given on the detergent label.
