pressure hose. Use the handle provided on the unit.  
• Always be certain the spray gun, nozzles and  
accessories are correctly attached.  
Do Not wear loose clothing, jewelry or anything that  
may be caught in the starter or other rotating parts.  
Do Not secure the spray gun in the (open) position.  
• High pressure spray may damage fragile items  
including glass. Do Not point spray gun at glass  
when in the jet spray mode.  
• Before starting the pressure washer in cold weather,  
check all parts of the equipment and be sure ice has  
not formed there.  
• Hold the spray gun firmly in your hand before you  
start the unit. Failure to do so could result in an  
injury from a whipping spray gun. Do Not leave the  
spray gun unattended while the machine is running.  
Never use a spray gun which does not have a  
trigger lock or trigger guard in place and in working  
order.  
• Keep the hose connected to machine or the spray  
gun while the system is pressurized. Disconnecting  
the hose while the unit is pressurized is dangerous.  
• The cleaning area should have adequate slopes and  
drainage to reduce the possibility of a fall due to  
slippery surfaces.  
• Units with broken or missing parts, or without  
protective housing or covers, should Never be  
operated.  
• Operate and store this unit on a stable surface.  
• Keep water spray away from electric wiring or fatal  
electric shock may result.  
• Check the fuel system for leaks or signs of

deterioration, such as chafed or spongy hose, loose  
or missing clamps, or damaged tank or cap. Correct  
all defects before operating the pressure washer.  
• The muffler and engine heat up during operation  
and remain hot immediately after shutting it down.  
Avoid contact with a hot muffler or engine as you  
could be severely burned.  
Do Not spray flammable liquids.  
• Use a respirator or mask whenever there is a  
chance that vapors may be inhaled. Read all  
instructions with mask so you are certain the mask  
will provide the necessary protection against inhaling  
harmful vapors.  
• High pressure hose can develop leaks from wear,  
kinking, abuse, etc. Water spraying from a leak is  
capable of injecting material into skin. Inspect hose  
each time before using it. Check all hoses for cuts,  
leaks, abrasions or bulging of cover, or damage or  
movement of couplings. If any of these conditions  
exist, replace hose immediately. Never repair high  
pressure hose. Replace it with another hose that  
exceeds the maximum pressure rating of your unit.  
Never aim the spray gun at people, animals or  
plants. The high pressure stream of water that this  
equipment produces can pierce skin and its  
underlying tissues, leading to serious injury and  
possible amputation.  
• The muffler and air cleaner must be installed and in  
good condition before operating the pressure  
washer. These components act as spark arresters if  
the engine backfires.  
Never allow any part of the body to come in contact  
with the fluid stream. Do Not come in contact with a  
fluid stream created by a leak in the high pressure  
hose.  
In the State of California a spark arrester is required  
by law (Section 4442 of the California Public  
Resources Code). Other states may have similar laws.  
Federal laws apply on federal lands.  
• Always wear eye protection when you use this  
equipment or when you are in the vicinity where the  
equipment is in use.  
• High pressure spray can cause paint chips or other  
particles to become airborne.  
NOTE: If you equip the muffler with a spark arrester, it  
must be maintained in effective working order. You can  
order a spark arrester through your authorized Briggs  
and Stratton service dealer.  
Do Not operate the pressure washer above the  
rated pressure.

• Apply detergent to a dry surface, starting from the  
bottom and working up.  
Applying Detergent with the  
Adjustable Nozzle  
• Allow the detergent to “soak in” for 3-5 minutes  
before washing and rinsing. Reapply as needed to  
prevent surface from drying.  
IMPORTANT: Use soaps designed specifically for  
pressure washers. Household detergents could  
damage the pump.  
• For washing, start at lower portion of area to be  
washed and work upward, using long, even,  
overlapping strokes.  
IMPORTANT: You must attach all hoses before you  
start the engine. Starting the engine without all the  
hoses connected and without the water turned ON will  
damage the pump.  
Pressure Washer Rinsing  
To apply detergent, follow these steps:  
WARNING! Be extremely careful if you must  
use the pressure washer from a ladder,  
• Review the use of adjustable nozzles.  
• Prepare the detergent solution as required by the  
job.  
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.  
• Hang the detergent solution on the hook of the  
wireform attached to the handle, as shown in  
Figure 15.  
Figure 15 — Insert Filter into Container  
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.  
• Remove the detergent siphoning tube from the clip  
on the handle.  
• 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.  
• Place the filter end of the detergent siphoning tube  
into the detergent container.  
• Start at the top of the area to be rinsed, working  
down with same overlapping strokes as you used for  
washing and applying detergent.  
CAUTION! Keep the detergent siphoning tube  
from coming in contact with the hot muffler. This  
will damage the plastic tube. When inserting the  
filter into a cleaning solution bottle, route the  
tube so as to keep it from inadvertently  
contacting the hot muffler.  
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 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 ground. This system  
prevents internal damage to the pump.  
• Slide the adjustable nozzle forward to low pressure  
mode. Detergent cannot be applied with the nozzle  
in high pressure position.  
• 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 (see  
“Connect Hose and Water Supply to Pump”,  
page 7). Start the engine.

GENERAL MAINTENANCE  
RECOMMENDATIONS  
The 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.  
WARNING! 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 Detergent Siphoning Tube  
• All maintenance in this manual and the engine  
owner’s manual should be made at least once each  
season.  
Examine the filter on the detergent tube and clean if  
clogged. The tube should fit tightly on the barbed  
fitting. Examine the tube for leaks or tears. Replace  
the filter or tube if either is damaged.  
• Once a year you should clean or replace the spark  
plug, clean or replace the air filter and check the  
spray gun and adjustable 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. Please refer to your engine  
owner’s manual for more details.  
Check Gun and Adjustable Nozzle  
Extension  
Examine the hose connection to the spray gun and  
make sure it is secure. Test the trigger by pressing it

PREPARING THE UNIT FOR  
STORAGE  
Water should not remain in the unit for long periods of  
time. Sediments or minerals can deposit on pump  
parts and “freeze” pump action. If you do not plan to  
use the pressure washer for more than 30 days, follow  
this procedure:  
Figure 18 — Backflushing the Nozzle  
1. Flush detergent siphoning tube by placing the filter  
into a pail of clean water while running pressure  
washer in low pressure mode (adjustable nozzle in  
the forward position). Flush for one to two  
minutes.  
• Reinstall the nozzle into the nozzle extension. Do  
Not overtighten.  
• Reconnect the nozzle extension to the spray gun.  
2. Shut off the engine and let it cool, then remove all  
hoses. Disconnect spark plug wire from spark  
plug.  
• Reconnect the water supply, turn on the water, and  
start the engine.  
Test the pressure washer by operating with nozzle in  
the high and in the low positions.  
3. 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. Insert  
detergent siphoning tube into clip on handle.  
O–Ring Maintenance  
Through the normal operation of your pressure  
washer, o–rings are used to keep the connections of  
the hoses and spray gun tight and leak–free. These o-  
rings may become worn or damaged.  
NOTE: To protect the unit from freezing temperatures,  
draw RV antifreeze (non-alcohol) into the pump by  
pouring the solution into a 3-foot section of garden  
hose connected to inlet adapter and pulling recoil  
handle twice.  
Provided with your pressure washer is an O–Ring  
Maintenance Kit which includes replacement o-rings,  
rubber washer and water inlet filter. Refer to the  
instruction sheet provided in the kit to service your  
unit’s o-rings. Note that you will not use all of the parts  
in the kit.  
4. Store unit in a clean, dry area.  
Storing the Engine  
See the engine owner’s manual for instructions on  
how to properly prepare the engine for storage.  
To remove a worn or damaged o–ring:  
• Use a small flathead screwdriver to get underneath  
the o-ring and pry it off.

* 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.
