OPERATING PROCEDURES (cont'd)

Quick Connect – Use the 0°, 15°, 25°, and 40° nozzles for high pressure-Figure 10. The size of the nozzle will determine the size of the fan spray. To change nozzles:

1.Shut off the pressure washer and turn off the water supply.

2.Pull trigger on gun handle to relieve any water pressure.

3.Pull quick connect coupler back and remove nozzle-Figure 11.

4.Pull quick connect coupler back and insert nozzle.

5.Release quick connect coupler and insure nozzle is secure.

To siphon chemicals/soaps, refer to low pressure operation below. Chemicals/soaps will not siphon in high pressure setting.

NOTE: On the Dual and Quick Connect wands the different degree nozzles will change the fan spray to be used in different applications.

0° nozzle – Used for a pinpoint stream. This nozzle stream is very powerful and covers a very small area of cleaning. This nozzle should only be used on surfaces that can withstand this high pressure such as metal or concrete.

15° and 25° nozzle – Used for less powerful stream which can cover a wider area. This nozzle is also very powerful and should only be used on surfaces that can withstand this high pressure.

40° nozzle – Used for the least powerful stream and covers a wide area of cleaning. This nozzle should be used for most general cleaning jobs.
