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.
· 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 upstream chemical injector is not recommended for use with this
pressure washer, and if used would obviously alter the 15-to-1 dilution ratio
and may cause pump damage.
CAUTION Chemicals Containing Muriatic Acid
Certain chemicals, such as bleach or those containing muriatic acid, will
cause pump damage if introduced upstream through the pump’s water inlet. Use
of chemicals not intended for pressure washers will void pump warranty.
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 approved pressure washer chemicals or chemicals specifically
formulated for use with pressure washers.
CAUTION Non-approved Chemicals
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 15 parts water to 1-part chemical solution.
2. Press the braided chemical hose over the chemical injector on the pump.
3. Submerge the suction strainer connected to the braided chemical hose into
a bucket containing the chemical solution.

Operation
Start-Up Procedures Start the Motor to Power the Pump
1. Make sure water supply is connected and primed.
CAUTION Warranty Void
Running the pump dry will cause damage and void the warranty.
2. To prevent accidental spraying, engage the safety latch on spray gun
trigger by rotating it to the locked position.
Apply Cleaning Chemical (if desired)
1. Make sure the chemical injector is properly set up according to the
instructions. Reference “Set Up for Chemical Spray” on the previous page.
2. Make sure the low-pressure BLACK nozzle is attached before beginning to
spray chemicals. Only the low-pressure black nozzle will allow chemicals to be
drawn through the chemical injector into the water stream.
3. Apply chemicals by squeezing the spray gun trigger. The chemical injector
will draw the chemical into the water stream.
4. Apply chemicals evenly to the cleaning surface. Never use more chemical
than is necessary to clean the surface.
5. Allow the chemicals time to react with the dirt before rinsing.
6. Prepare to rinse by changing to a high-pressure nozzle. Changing the
nozzle from the low-pressure
black nozzle to a high-pressure nozzle will stop the flow of chemicals into
the water stream.
Instructions for selecting a nozzle can be referenced in the “Connect Hoses,
Water Supply, and Spray Nozzle” section. See the subsection “Select Nozzle for
Spray Gun”. 7. Rinse with high-pressure spray as instructed below:
Begin High Pressure Spray
WARNING
High – Pressure Spraying
Safety
· Keep spray away from people. Never direct discharge stream at or near any
person. Do not allow any part of the body to come in contact with the fluid
stream. High-pressure spray can cause serious skin, eye, or falling injuries.
Injection injury will occur if high-pressure spray pierces the skin, injecting
liquid under the skin. Injection injury can result in blood poisoning and/or
severe tissue damage leading to infection, gangrene and possibly amputation.
Seek medical attention.
· Do not secure trigger open. To reduce risk of injury, do not attempt to
secure the spray gun open by blocking or tying the spray gun in the open
position.
· Prevent slips / loss of balance. High-pressure
spray could cause you to lose balance from
kickback forces, and wet surfaces can be slippery. – Keep good footing and
balance at all times. Do
not overreach.
– Do not stand on unstable support when spraying. – If spraying from an
elevated surface, use fall
protection because spray gun kickback can propel you off the elevated surface.
When spraying from a ladder or scaffolding, ensure it is firmly anchored from
sway or tip-over.
– Be aware of puddles and slippery surfaces.
Ensure there is adequate drainage to prevent pooling of water. · Prevent
surface damage & flying debris. Surfaces being sprayed must be strong enough
to withstand high-pressure spray or damage may result. In addition, high-
pressure spray will dislodge unsecured objects as well as surface chips and
debris, resulting in hazardous flying objects that can cause personal injury
or property damage. Do not spray brittle surfaces or breakable, fragile, or
unsecured objects such as: o stucco or laminar flagstone o some painted
surfaces o windows or glass doors, or mailboxes they
may break) o light fixtures, flowerbeds, mailboxes
o unsecured, lightweight objects
21
Operation
Procedure: 1. Install the high-pressure spray nozzle (always relieve
system pressure first and follow instructions for attaching a nozzle).
WARNING
High Pressure Spray Hazard · High pressure spray can cause injection injury,
eye
injury, and loss of balance. Serious injury could result from unintentional
release of high-pressure spray from the gun upon engaging the trigger. ·
ALWAYS turn Power Switch to OFF position and relieve system pressure when
leaving pressure washer unattended. · Total Start/Stop feature allows
temporary motor shut-off (STOP) when the Trigger is disengaged and allows
motor turn-on (START) when the Trigger is reengaged. This Feature should NEVER
be used to shut-off the pressure washer when not in use. 2. Clear the cleaning
area of all persons. Keep children and pets away. 3. Hold the spray gun firmly
with two hands and a sturdy stance — Gun kicks back when triggered.
4. Wash from the bottom to the top, using side-to-side motions. This washes
away heavy dirt and allows the detergent to soak as you work toward the top.
5. Use the width of the spray pattern to wash a wide path. Overlap spray
paths for complete coverage.
6. The nozzle should be 12″ to 24″ from the work, closer for tough areas.
7. Small parts should be washed in a basket, so the pressure does not push
them away. Larger, lightweight parts should be clamped down.
8. The pressure washer is set and locked to the maximum rated pressure when
it leaves the factory.
To reduce the pressure, turn the unloader knob counterclockwise. To return to
maximum pressure turn knob clockwise. 9. If temporarily interrupting spraying,
rotate trigger safety latch downward to the locked position to guard against
accidental trigger release.
WARNING
Warranty Void Do not attempt to alter the unloader valve’s maximum pressure.
Excess pressure could cause serious injury from escaping high-pressure fluids
and/or pump damage. Any alteration other than turning the adjustment knob will
void your warranty.
Spray Gun Safety Lock When not spraying, use the spray gun safety lock to
prevent accidental high-pressure discharge.
