Operation
Start-Up Procedures
Start the Motor to Power the Pump
1. Make sure water supply is connected and primed.
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
CAUTION
Warranty Void
Running the pump dry will cause damage and void the
warranty.
