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.
1)
Make sure the engine is off and the hose line
depressurized.
2)
To install the nozzle, pull the collar back and twist the
nozzle firmly into the coupler on the end of the wand
(Figure 3a).
Figure 3a
3)
Release the collar, making sure it springs back and re-seats to its original (non-retracted) position (Figure 3b).
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 tank and chemical injector,
which siphons cleaning chemicals into a low-pressure washer
spray downstream of the pump. Adequate suction pressure is created
only when the low pressure (black) spray nozzle
is used.
The introduction of cleaning chemicals via the chemical injector 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.
•
It mixes the cleaning chemical into a low-pressure spray. Cleaning chemicals applied under low pressure adhere better to the surface
being cleaned, allowing the formula time to react and remove dirt more effectively.
NOTICE
:
An external chemical injector pump is not recommended for use with this pressure washer.
WARNING
:
Chemical Spraying
•
Never spray acids, corrosives, or abrasive or flammable liquids. Breathing hazards, surface burns/corrosion, or fire/explosion
could result.
Follow the chemical manufacturer's label instructions for proper use and handling of the chemical. Understand all safety hazards and first aid
for all chemicals being used. Always wear protective gloves when handling and cleaning with chemicals, and wear other protective gear as
directed by chemical manufacturer. Always dispose of hazardous fluids per local, state, and national guidelines.
