Pull the slip ring on the female quick-fitting on the lance backwards.

the correct nozzle and pressure is identified for your task.

Leaks caused by loose fittings or worn or damaged hoses can result in injection injuries. Do not direct
the spray jet towards people or animals as the jet is very powerful and serious injury can occur. Wear the
appropriate safety equipment when operating this equipment.
Do not attempt to change the nozzles when the equipment is running. Always shut down the
engine completely before changing the nozzles.

itself by turning the pressure control knob.
Turn the knob clockwise to increase the pressure and counterclockwise
to decrease it (See
Fig 20
