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.
Note: An external
chemical injector pump
is not recommended for use with this pressure washer, and if
used would obviously alter the 13 to 1 dilution ratio.
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.
Acquire cleaning
chemical
Use only NorthStar pressure washer chemicals or chemicals specifically formulated for
use with pressure washers.
CAUTION:
Non-approved chemicals can damage pressure washer components (seals,
wand, hoses, pump, etc.) and be harmful to the environment.
Prepare for
chemical spray
(if planning to
use)
Prepare the pressure washer for chemical spraying using the following steps:
1.
Prepare (dilute) chemical cleaning solution as required for the job.
(Note: the chemical
solution will be
automatically mixed
with the water at a
ratio of 13 parts water
to 1 part chemical
solution.)
2.
Press the braided
chemical hose over
the chemical injector
not on pump.
3.
Submerge the suction
strainer connected to
the braided chemical hose into a bucket containing the chemical solution.
