OPERATOR’S MANUAL
COMPONENT IDENTIFICATION
Pump — Delivers a specific gpm to the high pressure
nozzle which develops pressure.
Spray Gun — Controls the application of water and
detergent onto cleaning surface with trigger device.
Includes safety latch.
Detergent Injector — Allows you to siphon and mix
detergents (Not Shown).
Wand — Must be connected to the spray gun.
High Pressure Hose — Connect one end to water
pump high pressure discharge nipple and the other
end to spray gun.
Rupture Disk — Secondary pressure release in the
unlikely event the unloader valve fails.
Unloader Valve — Safety device which, when the
spray gun closes, prevents over pressurization.
Note: If trigger on spray gun is released for more
than 1-2 minutes, water will leak from the pump
protector. Warm water will discharge from pump
protector onto oor. This system prevents internal
pump damage.

WARNING: Some detergents
may be harmful if inhaled or
ingested, causing severe nau-
sea, fainting or poisoning. The
harmful elements may cause
property damage or severe
injury.
STEP 1: Connect detergent injector to high pressure
outlet on machine, Connect high pressure hose
to injector with quick coupler. (Check to make sure
locking coupler sleeves are in proper position before
applying water pressure.)
STEP 2: Use detergent designed
specifically for pressure washers.
Household detergents could dam-
age the pump. Prepare detergent
solution as required by the manu-
facturer. Fill a container with pres-
sure washer detergent. Place the
filter end of detergent suction tube
into the detergent container.
STEP 3: With safety latch on spray
gun engaged, secure black deter-
gent nozzle into quick coupler.
NOTE: Detergent cannot be ap-
plied using yellow, green or white
nozzles.
STEP 4: With the motor running,
pull trigger to operate machine. Liquid detergent is
drawn into the machine and mixed with water. Apply
detergent to work area. Do not allow detergent to dry
on surface.
IMPORTANT: You must ush the detergent injec-
tion system after each use by placing the suction
tube into a bucket of clean water, then run the
pressure washer in low pressure for 1-2 minutes.
THERMAL PUMP
PROTECTOR
If you run the engine on your pressure washer for
1-2 minutes without pressing the trigger on the spray
gun, circulating water in the pump can reach high
temperatures. When the water reaches this tempera-
ture, the pump protector engages and cools the pump
by discharging the warm water onto the ground. This
thermal device prevents internal damage to the pump.
CLEANING TIPS
Pre-rinse cleaning surface with fresh water. Place de-
tergent suction tube directly into cleaning solution and
apply to surface at low pressure (for best results, limit
your work area to sections approximately 6 feet square
and always apply detergent from bottom to top). Allow
detergent to remain on surface 1-3 minutes. Do not
allow detergent to dry on surface. If surface appears
to be drying, simply wet down surface with fresh water.
If needed, use brush to remove stubborn dirt. Rinse at
high pressure from top to bottom in an even sweeping
motion keeping the spray nozzle approximately 1 foot
from cleaning surface. Use overlapping strokes as you
clean and rinse any surface. For best surface cleaning
action spray at a slight angle.
Recommendations:
• Before cleaning any surface, an inconspicuous
area should be cleaned to test spray pattern and
distance for maximum cleaning results.
• If painted surfaces are peeling or chipping,
use extreme caution as pressure washer may
remove the loose paint from the surface.
• Keep the spray nozzle a safe distance from the
surface you plan to clean. High pressure wash a
small area, then check the surface for damage. If
no damage is found, continue to pressure washing.
CAUTION - Never use:
• Bleach, chlorine products and other corrosive
chemicals
• Liquids containing solvents (i.e., paint thinner,
gasoline, oils)
• Tri-sodium phosphate products
• Ammonia products
• Acid-based products
These chemicals will harm the machine and will dam-
age the surface being cleaned.
RINSING
It will take a few seconds for the detergent to clear.
Apply safety latch to spray gun. Remove black soap
nozzle from the quick coupler. Select and install the
desired high pressure nozzle. NOTE: You can also stop
detergent from flowing by simply removing detergent
siphon tube from bottle.

minute.
STEP 2: Turn off the motor.
STEP 4: Disconnect the garden

CAUTION
Pump Storage
CAUTION: Always store your pres-
sure washer in a location where the
temperature will not fall below 32° F
(0° C). The pump in this machine is
susceptible to permanent damage if
frozen.
FREEZE DAMAGE IS NOT COVERED BY WAR-
RANTY.
If you must store your pressure washer in a location
where the temperature is below 32° F, you can minimize
the chance of damage to your machine by draining your
machine as follows:
1. Stop the pressure washer and detach supply hose
and high pressure hose. Squeeze the trigger of the
spray gun to drain all water from the wand and
hose.
2. Restart pressure washer and let it run briefly (about
5 seconds) until water no longer discharges from
the high pressure outlet.
In temperatures below 32° you may connect a bulkhead
fitting to the bottom of a bucket then attach a garden
hose to siphon anti-freeze into the pump.
