Release the collar, making sure it springs back and re-seats to its original (non-
retracted) position. (Fig. 9b).
Check the connection by pulling on the nozzle to
ensure a tight connection -- if correctly inserted, nozzle will rotate but not pull out.
WARNING
:
Make sure the nozzle is correctly inserted. Sprayer nozzle can become a projectile
and cause serious personal injury or property damage if not properly connected to
the spray gun. Do not attempt to use different types of nozzles that may not fit the
coupler.
STEP 2. SET UP FOR CHEMICAL SPRAY
(IF DESIRED)
Using the proper cleaning chemical for the application can speed up cleaning jobs tremendously.
Your pressure washer is equipped with a chemical injection point
on the downstream side of the pump
for introducing cleaning chemicals into the water stream. A braided chemical hose is provided to connect at
this point. Suction pressure at this connection automatically draws the chemical solution in through the hose,
mixing in 1 part chemical to 15 parts water. Adequate suction pressure is created only when the low pressure
(black) spray nozzle is used.
The introduction of cleaning chemicals via the chemical injection point affords the following advantages:
•
It protects the pump from damage because no chemical passes through the pump.
CAUTION:
Certain chemicals, such as bleach or those containing muriatic acid, will cause
pump damage if introduced upstream through the pump’s water inlet.
