Attach high
pressure hose Attach high pressure hose(s) to the pressure washer's water outlet.
WARNING :
NEVER operate this pump with components (such as hose, connections,
and spray gun) rated for lower pressure and/or temperature limits than the
machine's maximum rated pressure and temperature, or component could
rupture and cause serious personal injury from escaping high pressure
fluids.
1. See "Machine Component Identification" section of this manual for location
of the pressure washer's water outlet.
2. The high pressure hoses are equipped with quick couplers. To connect the
hose(s), simply pull the collar back and push the coupler onto the water
outlet nipple. (Figure 7a). The collar should slide over the ball bearings.
Figure 7a
3. Release the collar, making sure it springs back and re-seats to its original
(non-retracted) position. (Figure 7b). Check the connection by pulling on
the hose to ensure a positive connection.

Select spray
nozzle Your pressure washer is equipped with twelve high-pressure nozzles (eight
#3.5 nozzles and four #7.0 nozzles) and three low-pressure nozzles (two #3.5
and one #7.0).
Select nozzles based on the type of job you are doing (color of nozzle) and
whether you are using two guns or one gun (size of nozzle).
1.
One gun vs. two gun use :
a) Use a #7.0 nozzle for single gun operation. This will ensure the rated
flow and psi are achieved.
Note: Hook up both guns even if you will be using only a single gun.
This will stop water from exiting the other hose while spraying
