HOW TO USE YOUR
PRESSURE WASHER
Figure 10 — Squeeze trigger to relieve water
pressure, release trigger and turn
the safety latch ON.
If you have any problems operating your pressure
washer, please call the pressure washer helpline at
1-800-270-1408.
You have assembled your high pressure washer and
have prepared the engine for starting. You are now
ready to clean your car, boat or the outside of a building or whatever you plan to clean.
How to Start Your Engine
The best way to start your engine-powered pressure
washer for the first time is to follow these instructions
step-by-step. This starting information also applies
whenever you start the engine after you have let the
pressure washer sit idle for at least a day.
• Place the pressure washer in an area close enough
to an outside water source that can flow at a rate of
2 gallons per minute.
• Check that the high pressure hose is tightly connected to the spray gun and to the pump. See
ASSEMBLY section for illustrations.
• Connect the garden hose to water inlet on the pressure washer pump and turn on the water.
IMPORTANT: Do not run pump without the water
supply connected and turned on. You must follow this
caution or the pump will be damaged.
• Move the Throttle Control Lever to the “Fast”
position
• Set Choke Lever to “Choke” position. Note: This is
a multi-position choke.
Note: For a warm engine, be sure the Throttle Control
Lever is in the “Fast” position and the Choke Lever is in
the “Run” position.
Safety Latch ON
• Grasp rope handle and pull slowly until you feel
some resistance. Then pull cord rapidly to overcome compression, prevent kickback and start the
engine. Let rope return to starter slowly.
Note: Always keep the Throttle Control Lever in the
“Fast” position when operating the pressure washer.
• When the engine starts, gradually move the Choke
Lever from one position to the next until it is in the
“Run” position.
If after 3 pulls the engine fails to start, move the Choke
Lever to the “Run” position and pull the recoil starter
handle rapidly (Max. 3 pulls).
How to Stop Your Pressure
Washer
• Move the Throttle Control Lever to the “Slow” position.
• Wait for the engine to idle down.
• Move the Throttle Lever Lever to the “Stop” position.
• Simply shutting off the engine will not release pressure in the system. Squeeze trigger on the spray
gun to relieve pressure in the hose.
• Squeeze the trigger on the spray gun to relieve the
air pressure caused by turning ON the water.
Water will spew out the gun in a thin stream. This
will make it easier to pull start the engine. Release
the trigger.
• Apply the safety latch to the spray gun trigger
(Figure 10).

• If you get spray nozzle too close, especially using
high pressure mode, you may damage the cleaning
surface.
• Do not get closer than 6 inches when cleaning
automobile tires.
How to Use the Adjustable
Nozzle
You now should know how to START your pressure
washer and how to STOP it. The information in this
section will tell you how to adjust the spray pattern
and apply detergent or any other cleaning chemicals.
Figure 12 — Test the spray pattern.
DANGER! Never adjust spray pattern
when spraying. Never put hands in front
of nozzle to adjust spray pattern.
On the end of your spray gun is a nozzle that you can
slide forward and backward and that you can also
twist from side to side. With the adjustable nozzle you
can adjust the spray pattern to be either high pressure or low pressure. You can also adjust the spray
so it is concentrated in a stream pattern or expanded
into a fan pattern.
• Slide the nozzle forward when you wish to adjust
the spray to low pressure mode (Figure 11). Slide
the nozzle backward to achieve high pressure.
• Point the nozzle toward the ground and press the
trigger to test the pattern (Figure 12).
• Twisting the nozzle adjusts the spray pattern from a
narrow pattern to a fan pattern.
• For most effective cleaning, keep spray nozzle
between 8 to 24 inches away from cleaning surface.

• Allow the detergent to soak 3-5 minutes before
washing and rinsing.
• For washing, start at lower portion of area to be
washed and work upward, using long, even, overlapping strokes.
Applying Detergent with the
Adjustable Nozzle
IMPORTANT: Use soaps designed specifically for
pressure washers. Household detergents could
damage the pump.
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.
To apply detergent follow these steps:
• Review the use of adjustable nozzles on Page 10.
• Prepare the detergent solution as required by the
job.
• Hang the detergent solution on the hook of the
wireform as shown in Figure 13.
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
agent bottle, route the tube to keep it from
inadvertently contacting the hot muffler.
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 force you to fall. The high pressure spray could also force you to fall if you
are too close to the cleaning surface.
For Rinsing:
• Slide nozzle backward (see Figure 11) to high pressure and wait for detergent to clear.
• Keep the spray gun a safe distance from the area
you plan to spray.
• Apply a high pressure spray to an small area and
then check the surface for damage. If no damage
is found, you can assume it is okay to continue
cleaning.
• Start at top of area to be rinsed, working down with
same overlapping strokes as you used for cleaning.
Note: You can also stop detergent from flowing by
simply removing detergent siphoning tube from bottle.
Figure 13 — Insert the small filter into container
of cleaning solution.
• Place small filter of the clear, detergent siphoning
tube into the detergent container.
• Slide the adjustable nozzle forward to low pressure
mode. Detergent cannot be applied with nozzle in
high pressure position.
IMPORTANT: Detergent cannot be applied without
the water source turned on.
• Make sure garden hose is connected to water inlet.
Check that high pressure hose is connected to
spray gun and pump (see ASSEMBLY), and start
the engine.
• Apply detergent to a dry surface, starting from the
bottom and working up.
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.

GENERAL MAINTENANCE
RECOMMENDATIONS
Check Detergent Siphoning Tube
Examine the filter on the detergent siphoning tube
and clean if clogged. Tube should fit tightly on barbed
fitting. Examine tube for leaks or tears. Replace the
filter or tube if either is damaged.
The warranty of the high pressure washer does not
cover items that have been subjected to operator
abuse or negligence. To receive full value from the

washer as instructed in this manual.
• Some adjustments will need to be made periodically
to properly maintain your high pressure washer.
• All adjustments in the “Service and Adjustments”
section of this manual should be made at least once
each season.
• Once a year you should clean or replace the spark
plug and clean or replace the air filter and check the
gun and wand 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.
Check Gun and Nozzle Extension
Examine hose connection to gun and make sure it is
secure. Test trigger by pressing it and making sure it
springs back into place when you release it. Put safety
latch in ON position and test trigger. You should not be
able to press trigger.
Purge Pump of Air and
Contaminants
To remove the air from the pump, follow these steps:
• Set up the pressure washer as described in the
ASSEMBLY section and connect the water supply.
• Remove the nozzle extension from the gun.

PRESSURE WASHER
MAINTENANCE
Check and Clean Inlet Screen
Cleaning Detergent Siphoning
Tube
Examine screen on the water inlet. Clean if the screen
is clogged or replace if screen is damaged.
If you have used the detergent siphoning tube you
must flush it with clean water before stopping the
engine.
• Place detergent siphoning tube in a bucket full of
clean water.
• Flush for 1-2 minutes.
• Shut off the engine.
Important: Simply shutting OFF engine will not release
pressure in the system. When engine has shut down,
squeeze the trigger on the gun to relieve the pressure
in the hose.
Check High Pressure Hose
High pressure hose can develop leaks from wear,
kinking, or abuse. Inspect hose each time before using
it. Check for cuts, leaks, abrasions or bulging of cover,
damage or movement of couplings. If any of these
conditions exist, replace hose immediately.
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 meets
the maximum pressure rating of your
pressure washer.

• Remove additional debris by back flushing water
supply through nozzle extension (Figure 18). Back
flush between 30 to 60 seconds. Turn nozzle extension to stream spray and move nozzle from low to
high while flushing.
Nozzle Maintenance
If the adjustable nozzle becomes restricted or
clogged with foreign materials, such as dirt, excessive
pump pressure may develop. If this nozzle becomes
partially clogged, it can cause a pulsing sensation
during use. This generally is not a pump related
problem, but rather a clogged or partially restricted
adjustable nozzle.
If the adjustable nozzle becomes clogged or partially
restricted, immediately clean the nozzle with the kit
included with your pressure washer by following
these instructions:
• Shut off the engine and turn off the water supply.
• Separate the nozzle extension from the gun.
• Adjust the nozzle extension to the stream position.
• Remove nozzle from the end of the nozzle extension
(Figure 17) using a 2mm or 5/64 allen wrench (like
the one included in the kit).
• Use the wire included in the kit (Figure 17) or a
small paper clip to free the foreign materials clogging or restricting the nozzle.
Figure 18 — Backflushing the nozzle.
• Reinstall nozzle into the nozzle extension. DO NOT
over tighten.
• Reconnect the nozzle extension to the gun.
• 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 position.

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, the GN-Series engines need periodic parts service and replacement to perform well. This warranty will not cover repair when normal use has
exhausted the life of a part or an engine.
THIS WARRANTY DOES NOT INCLUDE: Used products and demonstration equipment. Parts such as

THIS WARRANTY IS IN PLACE OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, SPECIFICALLY,
GENERAC 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 GENERAC’s NEGLIGENCE. 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 GENERAC authorized warranty service facility or call 1-800-333-1322. Warranty service can be performed only by a GENERAC 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
