Nozzles:
0° Red Nozzle
This nozzle delivers an extremely powerful pinpoint
stream that covers a very small cleaning area.
15° Yellow Nozzle
This nozzle delivers a powerful 15° spray pattern
for intense cleaning of small areas.
25° Green Nozzle
This nozzle delivers a 25° spray pattern for intense
cleaning of larger areas.
40° White Nozzle
This nozzle delivers a 40° spray pattern and a
less powerful stream of water. It covers a wide
area of cleaning.
Chemical Black Nozzle
This nozzle is used to apply chemicals or cleaning
solutions. It has the least powerful stream.
Always double-check coupler connections on
all fittings. Improperly connected fittings can
blow apart under pressure causing severe
personal injury and/or equipment damage.
NOTICE
Always try a nozzle on a small test area or
piece of test material to determine if it is the
correct nozzle for the task. Some nozzles
provide so much pressure they can destroy
even sturdy materials.
Applying Chemicals
Applying chemicals or cleaning solvents
is a low pressure operation. Use only the
chemical nozzle to apply chemicals or
solvents.
Use only household detergents, cleaners, and
degreasers recommended for use in pressure
washers. NEVER use toxic or corrosive
chemicals, acids, poisons, insecticides, or
flammable solvents such as gasoline or
kerosene with your pressure washer. Failure
to follow this warning could result in machine
failure, significant property damage, severe
personal injury, or death.
