Select the Spray
Nozzle
Your pressure washer is equipped with 15 high-pressure nozzles and 3 low-pressure nozzles. (1 #7.0 Steam and 2
#3.0 Steam nozzles). Generally, the wider the spray angle of the nozzle, the lower the spray pressure produced. Select
nozzles based on the type of job you are doing (color of nozzle) and whether you are using two guns or one (size of
nozzle).
1. One gun vs. two-gun use:
a) Use a #9.0 nozzle for single gun operation. This will ensure the rated flow and psi are achieved.
b) Use two #4.5 nozzles when operating dual guns.
c) Use a #7.0 yellow steam nozzle for single gun operation.
d) Use two #3.0 yellow steam nozzles when operating dual guns.
WARNING: NEVER use #9.0 nozzles when operating both guns. If two operators use #9.0 nozzles and one
operator releases the trigger on their gun, the flow through the second operator’s gun will suddenly increase from 4.5 to
8 GPM. This will cause the second operator’s gun to kick without warning, which could result in loss of balance and/or
spraying control.
2. Type of cleaning job:
Select the appropriate color nozzle for the job based on the following table. The wider the spray angle of the nozzle,
the lower the spray pressure produced.

NOTE:
You must use the low-pressure black nozzle for spraying chemicals. For dual gun use with chemicals, you will
need a black, #40.0 nozzle on each gun – you will not be able to spray chemicals out of one gun and plain water
out of the other gun at the same time.
Attach the Nozzle
Attach nozzle to the spray gun.
WARNING: DEPRESSURIZE FIRST
Any time you remove/install/change a nozzle, you must depressurize hose line by squeezing the spray gun trigger
while the engine is off. Even if the engine has been off for a long period of time, the hose may remain dangerously
pressurized.
