0˚ - RED - Blast Pressure Nozzle - Higher pressure and lower flow
for stubborn or hard to reach surfaces such as second story
surfaces, paint removal, oil stains, rust removal or other stubborn
substances (tar, gum, grease, wax, etc.). Avoid using this nozzle
on more fragile surfaces such as wood.
15˚ - YELLOW - High Pressure Nozzle - High pressure and low/-
medium flow, typically used for surface preparation such as
removing dirt, mildew, paint, rust from steel and oxidation from
aluminum. Can be used on most surfaces.
25˚ - GREEN - Clean Pressure Nozzle - Medium pressure and
medium flow for most all-purpose cleaning such as home siding,
roofs, gutters, downspouts, brick patios, wooden decks, driveways
and sidewalks, garage doors, etc.
40˚ - WHITE - Wash Pressure Nozzle - Lower pressure and higher
flow for gentle cleaning of cars/trucks, boats, RV’s, patio furniture,
lawn equipment, glass, and other delicate surfaces.
WARNING! High-pressure jets can be dangerous if subject to misuse. The
jet must not be directed at persons, pets, live electrical equipment, or the
appliance itself.
1. Turn off the pressure washer and shut off the water supply. Hold the
trigger to release remaining water pressure.
2. Engage the safety lock on the trigger gun by pushing in the safety lock.
CAUTION! NEVER change nozzles without first locking the safety lock on
the trigger gun.
3. Insert the nozzle into the end of the spray wand and slide the quick
connect downwards slightly to snap-in and secure.

WASHING WITH DETERGENTS
How to disconnect a nozzle from the spray wand:
WARNING! Do not change the nozzle while the trigger is engaged. Doing so
could result in damage to the pressure washer or serious injury to the user.
1. Turn off the pressure washer and shut off the water supply. Hold the
trigger to release remaining water pressure.
2. Engage the safety lock on the trigger handle by pushing in the safety lock.
3. Pull the quick connect at the top of the spray wand downwards and
remove the nozzle.
1. Remove the cap from the pressure washer detergent bottle and fill it with
detergent designed specifically for use with pressure washers.
2. Attach the detergent bottle adapter to the spray wand.
3. Attach the detergent bottle onto the adapter of the spray wand by holding
down the bottle’s yellow release button and making sure to align the small
black node on the lid with the slot on the adapter and pushing in to secure
and connect.
When cleaning with the pressure washer, some cleaning tasks may require
using detergent for more effective dirt and stain removal.
WARNING! Only use detergents designed for Pressure Washers.
DO NOT USE household detergents, acids, alkaline solutions, bleaches,
solvents, flammable material, or industrial grade solutions. These could
damage the pressure washer. Many detergents may require mixing prior to
use. Prepare the cleaning solution as per manufacturer instructions.
11
4. Turn on the pressure washer. Hold the trigger to operate the unit. The
liquid detergent will automatically mix with water and be discharged
through the nozzle.
5. Allow the detergent to remain on the surface for a short time before
detaching the detergent bottle and rinsing. Do not allow the detergent to
dry on the surface.
CAUTION! Damage may occur to painted surfaces if the detergent is left
to dry on the surface. Wash and rinse a small section at a time. Avoid
working on hot surfaces or in direct sunlight.
6. Once finished using the detergent, fill the detergent bottle with fresh
water. Siphon water at low-pressure for one minute to rinse the bottle
until it is thoroughly cleaned.
CAUTION! Failure to follow these cleaning instructions will cause the
injection system to become clogged and inoperable.
7. Press the yellow button on the top of the detergent bottle and detach the
bottle from the adapter.
SHUTTING DOWN
1. Turn the power switch to the OFF position and unplug the power cord
from the outlet.
2. Turn off the water supply.
3. Hold the trigger on the trigger gun to release water pressure.
WARNING! You must depressurize the unit! Failure to do so could result
in personal injury due to discharge of high-pressure water unexpectedly.
6. Disconnect the other end of the
high-pressure hose from the washer
by pressing the hose release button
and pulling the hose out.
7. Engage the gun safety lock on the
trigger gun.
5. Disconnect the high-pressure hose
from the trigger gun by pressing the
quick release lever and pulling the
hose down.
4. Disconnect the garden hose from the
water inlet on the unit.

1. Unscrew the spray
wand from the trigger
gun. Store the trigger
gun and spray wand
on the holders locat-
ed on the side of the
unit.
2. Hang both the power
cord and the
high-pressure hose
on their respective
holders.
• Ensure all water connections are disconnected from the pressure
washer.
• Turn on the pressure washer for a few seconds until the remaining water
in the pump flushes out. Turn off immediately.
• Do not allow the high-pressure hose to become kinked.
• Store the machine and accessories in a room that does not reach freez-
ing temperatures.
• Store the pressure washer indoors in a dry, covered area where it is not
subject to adverse weather conditions.
• Always empty water from all hoses, the pump, and the detergent bottle
before storing.
CAUTION! Always store your pressure washer in a location where the
temperature will not fall below 32ºF (0ºC). The pump in this machine is
susceptible to permanent damage if it freezes.
If you must store your pressure washer in a location where the temperature
falls below 32ºF (0ºC), you can minimize the chance of damage to your
machine by following these steps:
WINTERIZING AND LONG-TERM STORAGE
13
• Do not store near a furnace or other sources of heat that may dry out the
pump seals.
WARNING: Never start up a frozen pressure washer!
CAUTION! Before working on the
pressure washer, disconnect the
plug from the power supply
socket.
3. Remove the nozzle and clean with
the nozzle needle provided.
Unscrew the spray wand from the
trigger gun. Clean the quick
connect end of the spray wand,
making sure there is no dirt or
sediment.
4. Remove additional debris by back flushing water through the nozzle and
spray wand. To do this, place the end of your garden hose (with water
running) to the tip of the nozzle, pushing water and debris out of the back
opening of the nozzle and spray wand.
1. To ensure good performance,
check and clean the water inlet.
2. Remove the Inlet water hose
connector and rinse the filter with
water to prevent any foreign
matter from clogging the pump.
