• 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.

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.

* 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.
