COMPONENT IDENTIFICATION
Wand — Must be connected to the spray gun.
Swivel Connector - Allows free range of movement
to avoid coiling hoses.
Note: If trigger on spray gun is released for more
than 2 minutes, water will leak from pump protec-
tor valve. Warm water will discharge onto floor and
cool water will allow the pump protector to seal.
This system prevents internal pump damage.
Detergent Injector - Allows you to siphon and mix
detergents, when used with soap nozzle.
High Pressure Hose — Connect one end to water
pump discharge nipple and the other end to spray gun.
Spray Gun — Controls the application of water and
detergent onto cleaning surface with trigger device.
Includes safety latch.

PRESSURE WASHER OPERATOR’S MANUAL
OPERATOR’S MANUAL PRESSURE WASHER
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: Use detergent designed
specifically for pressure wash-
ers. Household detergents could
damage the pump. Prepare deter-
gent solution as required by the
manufacturer. Fill a container with
pressure washer detergent. Place
the filter end of detergent suction
tube into the detergent container.
STEP 2: Apply safety latch
to spray gun trigger. Secure
black detergent nozzle into
quick coupler. NOTE: Deter-
gent cannot be applied using
the Yellow nozzle.
STEP 3: With the motor run-
ning, 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 flush 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 PROTECTION
If you run your pressure washer for 2 minutes without
pressing the trigger on the spray gun, circulating water
in the pump can reach high temperatures. When the
water reaches this temperature, 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
detergent suction tube directly into cleaning solution
and apply to surface at low pressure (for best results,
limit your work area to sections approximately 6’ square
and always apply detergent from bottom to top). Allow
detergent to remain on surface 1-3 minutes. Do not al-
low 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’ 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 dam-
age. If no damage is found, continue to pressure
washing.
CAUTION - Never use:
• Bleach, chlorine or 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.

gent injector. Pull trigger
on spray gun and siphon
water for one minute.
STEP 2: Turn off machine
by pushing switch on front
panel.
STEP 5: Disconnect the garden hose
from the water inlet on the machine.
Protect from freezing.
STEP 6: Disconnect the high pressure
hose from high pressure outlet.
STEP 7: Engage the
spray gun safety lock.
STEP 4: Press trigger to

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 WARRAN-
TY.
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.
