pressure nozzles (White, Green, Yellow, or Red).
• Make sure the garden hose is connected to the water
inlet. Check that the high pressure hose is connected to
the spray gun and the pump and start the engine.
• Apply the detergent to a dry surface, starting at lower
portion of area to be washed and work upward, using
long, even, overlapping strokes. Do Not allow the
detergent to dry on. This will prevent streaking.
• Apply a high pressure spray to a small area and then
check the surface for damage. If no damage is found, you
can assume it is okay to continue cleaning.
• Allow the detergent to soak in between 3–5 minutes
before washing and rinsing. Reapply as needed to prevent
surface from drying.
• Start at the top of the area to be rinsed, working down
with same overlapping strokes as you used for cleaning.
Automatic Cool Down System
Pressure Washer Rinsing
(also known as Thermal Relief)
WARNING! Be extremely careful if you must use
the pressure washer from a ladder, scaffolding or
any other relatively unstable location. Hose water
pressure builds as you climb. When you press the
trigger, the recoil from the initial spray can be very
strong. The high pressure spray could cause you to
fall if you are too close to the cleaning surface.
If you run the engine on your pressure washer for
3–5 minutes without pressing the trigger on the spray gun,
circulating water in the pump can reach a temperature
between 140–145°F. When the water reaches this
temperature, the automatic cool down system engages and
cools the pump by discharging the warm water onto
the base and ground. This system prevents internal
damage to the pump.

GENERAL MAINTENANCE
RECOMMENDATIONS
The high pressure washer warranty does not cover items
that have been subjected to operator abuse or negligence.
To receive full value from the warranty, the operator must
maintain the high pressure washer as instructed in this
manual.
DANGER! Water spraying from a leak is capable
of injecting material into skin. Inspect hose each
time before using it. Never repair a high pressure
hose. Replace it with another hose that exceeds the
maximum pressure rating of your pressure washer.
• Some adjustments will need to be made periodically to
properly maintain your high pressure washer.
Check Gun and Nozzle Extension
• All adjustments in the Maintenance section of this manual
should be made at least once each season.
Examine the hose connection to the gun and make sure it
is secure. Test the trigger by pressing it and making sure it
springs back into place when you release it. Put the safety
latch in the on position and test the trigger. You should not
be able to press the trigger.
• Once a year you should clean or replace the spark plug
and clean or replace the air filter and check the gun and
nozzle extension assembly for wear. A new spark plug
and clean air filter assure proper fuel–air mixture and
help your engine run better and last longer.

5.
To remove a worn or damaged o–ring:
• Use a small flathead screwdriver to get underneath the
o-ring and pry it off.
Empty the pump of all pumped liquids by pulling the
recoil handle about 6 times. This should remove most
of the liquid in the pump.
NOTE: To protect the unit from freezing temperatures,
draw RV antifreeze (no alcohol) into the pump by pouring
the antifreeze into a 3–foot section of garden hose
connected to inlet adapter and pulling recoil handle twice.
This process is also recommended to avoid lime/calcium
build-up in the pump during longer-term storage.

* NOTE: For the purpose of this warranty “consumer” use means personal residential household use by
original purchaser. “Commercial” use means all other uses, including rental, construction, commercial and
income producing purposes. Once a pressure washer has experienced commercial use, it shall thereafter
be considered a commercial use pressure washer for the purposes of this warranty.
During said warranty period, the COMPANY will, at its option, repair or replace any part which, upon examination by the
COMPANY or COMPANY-Authorized Dealers, is found to be defective under normal use and service**. All transportation
costs under warranty, including return to the factory if necessary, are to be borne by the purchaser and prepaid by the
purchaser.
** NORMAL WEAR: As with all mechanical devices, pressure washers need periodic parts service and
replacement to perform well. This warranty does not cover repair when normal use has exhausted the life
of a part or pressure washer pump.
This warranty does not include: Used products and demonstration equipment. Parts, such as GUNS, HOSES, WANDS,
NOZZLES or other wear items such as quick couplers, oil, gauges, belts, o-rings, filters, pump packing, etc. Pumps which
have been run without water supplied. Damage or malfunctions resulting from: accidents, abuse, modifications, alterations,
or improper servicing. Freezing or chemical deterioration. Normal maintenance such as adjustments, fuel system cleaning
and obstruction (due to chemical, dirt, carbon or lime, etc.).
THIS WARRANTY IS IN PLACE OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, SPECIFICALLY,
THE COMPANY MAKES NO OTHER WARRANTIES AS TO MERCHANTABILITY OR FITNESS FOR A
PARTICULAR PURPOSE. THE DURATION OF ANY IMPLIED WARRANTIES WHICH CANNOT BE
DISCLAIMED IS LIMITED TO THE TIME PERIOD AS SPECIFIED IN THE EXPRESS WARRANTY. LIABILITY
FOR CONSEQUENTIAL, INCIDENTAL, OR SPECIAL DAMAGES UNDER ANY AND ALL WARRANTIES
IS EXCLUDED, EVEN IF SUCH DAMAGES ARE A DIRECT RESULT OF THE COMPANY'S NEGLIGENCE.
THE COMPANY ALSO DISCLAIMS ANY RESPONSIBILITY FOR INCIDENTAL OR CONSEQUENTIAL
DAMAGES SUCH AS THE LOSS OF TIME OR THE USE OF THE POWER EQUIPMENT, OR ANY
COMMERCIAL LOSS DUE TO THE FAILURE OF THE EQUIPMENT: AND ANY IMPLIED WARRANTIES
ARE LIMITED TO THE DURATION OF THIS WRITTEN WARRANTY.
Some states do not allow limitations on how long an implied warranty lasts, or the exclusion or limitation of incidental or
consequential damages, so the above limitations or exclusions may not apply to you. This warranty gives you specific legal
rights and you may also have other rights, which vary from state to state.
For service, see your nearest COMPANY-Authorized warranty service facility or call 1-877-544-0982. Warranty service
can be performed only by a COMPANY-Authorized service facility. This warranty will not apply to service at any other
facility. At the time of requesting warranty service, evidence of original purchase date must be presented.
