Pressure Washer Rinsing

WARNING:

Be extremely careful if you must use the pressure washer from a ladder, scaffolding or any other relatively unstable location. Pressure in a running washer builds as you climb. When you press the trigger, the recoil from the initial spray could cause you to fall. The high pressure spray could also cause you to fall if you are too close to the cleaning surface.

For Rinsing:

Slide the nozzle backward to high pressure, press the trigger and wait for the detergent to clear.

NOTE:

You can also stop detergent from flowing by simply removing detergent siphoning tube from bottle.

Keep the spray gun a safe distance from the area you plan to spray.

Apply a high pressure spray to a small area, then check the surface for damage. If no damage is found, it is okay to continue cleaning.

Start at the top of the area to be rinsed, working down with same overlapping strokes as you used for washing and applying detergent.

Automatic Cool Down System

(Thermal Relief)

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 140145°F. When the water reaches this temperature, the automatic cool down system engages and cools the pump by

discharging the warm water onto the ground.

* 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. 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.
