thoroughly. Failure to follow
instructions could cause mal-
function of the machine and
result in death, serious bodily
injury and/or property damage.
2. Know how to stop the ma-
chine and bleed pressure quickly. Be thoroughly
familiar with the controls.
3. Stay alert — watch what you are doing.
4. All installations must comply with local codes.
Contact your electrician, plumber, utility company
or the selling distributor for specic details. If your
machine is rated 250 volts or less, single phase will
be provided with a ground fault circuit interrupter
(GFCI). If rated more than 250 volts, or more than
single phase this product should only be connected
to a power supply receptacle protected by a GFCI.
DANGER: Improper connection of the equipment-
grounding conductor can result in a risk of elec-
trocution. Check with a qualified electrician or
service personnel if you are in doubt as to whether
the outlet is properly grounded. Do not modify the
plug provided with the product - if it will not t the
outlet, have a proper outlet installed by a qualied
electrician. Do not use any type of adaptor with
this product
WARNING
KEEP WATER
SPRAY AWAY FROM

WARNING: Keep wand, hose, and
water spray away from electric
wiring or fatal electric shock may
result.
5. To protect the operator from
electrical shock, the machine
must be electrically grounded.
It is the responsibility of the
owner to connect this machine
to a UL grounded receptacle of proper voltage and
amperage ratings. Do not spray water on or near
electrical components. Do not touch machine with
wet hands or while standing in water. Always dis-
connect power before servicing.

COMPONENT IDENTIFICATION
Pump — Develops high pressure.
Spray Gun — Controls the application of water and
detergent onto cleaning surface with trigger device.
Includes safety latch.
Wand — Must be connected to the spray gun.
Unloader — Safety device that relieves pressure when
spray gun trigger is closed.
High Pressure Hose — Connect one end to water
pump discharge nipple and the other end to spray gun.
Pump Protector — Cycles fresh cool water through
pump when recirculating water reaches 140°F.
GFCI — Ground fault circuit interrupter trips when
voltage leaks to ground.
Note:If trigger on spray gun is released for more
than 1-2 minutes, water will leak from valve. Warm
water will discharge from pump protector onto
oor. This system prevents internal pump damage.

PRESSURE WASHER OPERATOR’S MANUAL
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 discharge nipple
on machine. Connect high pressure hose to injector
with quick coupler. (Check to make sure locking cou-
pler sleeves are in proper position before applying
water pressure).
STEP 2: 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 lter end of detergent suction
tube into the detergent container.
STEP 3: With safety latch on
spray gun engaged, secure black
detergent nozzle into quick cou-
pler. NOTE: Detergent cannot be
applied using a pressure nozzle.
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 PROTECTION
If you run the motor on your pressure washer for 1-2
minutes without pressing the trigger on the spray gun,
circulating water in the pump can reach high tempera-
tures. When the water reaches this temperature, the
pump protector engages and cools the pump by dis-
charging 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, other corrosive chemicals
• Liquids containing solvents (i.e., paint thinners,
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 owing by simply removing detergent
siphon tube from bottle.

SHUTTING DOWN AND CLEAN-UP
STEP 1: Remove deter-
gent suction tube from

detergent nozzle. Pull
trigger on spray gun and
siphon fresh clean water
for one minute.
STEP 2: Turn off machine
by turning switch to “OFF”
switch.
STEP 5: Disconnect the
garden hose from the wa-
ter inlet on the machine.
STEP 6: Disconnect the
high pressure hose from
the discharge nipple.
STEP 7: Engage the
spray gun safety lock.
STEP 4: Press trigger to
release water pressure.

STORAGE
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 B Y WA R -
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 trigger of spray
gun to drain all water from the wand and hose.
2. Restart pressure washer and let it run briey (about
5 seconds) until water no longer discharges from
the high pressure outlet.
STEP 3: Turn off water
supply.
