IMPORTANT: It is important to prevent gum deposits

from forming in essential fuel system parts, such as the
carburetor, fuel filter, fuel hose or tank during storage.Also,
experience indicates that alcohol–blended fuels (called
gasohol, ethanol or methanol) can attract moisture, which
leads to separation and formation of acids during storage.
Acidic gas can damage the fuel system of an engine while in
storage.

To avoid engine problems, the fuel system should be
emptied before storage of 30 days or longer. See “Storage”
on page 12. Never use engine or carburetor cleaner
products in the fuel tank or permanent damage may occur.

Connect Hose and Water Supply to

Pump

IMPORTANT: You must assemble the nozzle extension

to the spray gun and attach all hoses before you start the
engine. Starting engine without all hoses connected and
water supplied will damage the pump.

• Uncoil the high pressure hose and attach one end of the
hose to the base of the spray gun (Figure 3).Tighten by
hand.

• Attach the other end of the high pressure hose to the

high pressure outlet on the pump (Figure 4).Tighten by
hand.

• Before you connect your garden hose to the water inlet,
inspect the inlet screen (Figure 5). Clean the screen if it
contains debris or have it replaced if damaged. DO NOT
RUN THE PRESSURE WASHER IF THE SCREEN IS
DAMAGED.

• Run water through your garden hose for 30 seconds to
clean out any debris.

IMPORTANT: Do Not siphon standing water for the

all of the following.

• Check that oil has been added to the proper level in the
engine crankcase.

• Add the proper gasoline to fuel tank.

• Check for properly tightened hose connections (high
pressure and water supply) and that there are no kinks,
cuts, or damage to the high pressure hose.

• Provide a proper water supply at an adequate flow.

• Be sure to read "Safety Rules" and "How To Use Your
Pressure Washer" before using the pressure washer.

HOW TO USE YOUR

PRESSURE WASHER

If you have any problems operating your pressure washer,
please contact the local Snapper service center.

How to Start Your Pressure Washer

To start your pressure washer for the first time, follow
these instructions step-by-step.This starting information
also applies if 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 capable of supplying water at a
flow rate greater than 2.8 gallons per minute.

• Check that the high pressure hose is tightly connected
to the spray gun and to the pump. See “Preparing
Pressure Washer for Use” for illustrations.

• Make sure unit is in a level position.

• Connect the garden hose to the water inlet on the
pressure washer pump. Turn ON the water.

CAUTION! Do Not run the pump without the water

supply connected and turned on.You must follow this
caution or the pump will be damaged.

• Squeeze the trigger on the spray gun until you have a
steady stream of water.This purges the pump of air and
impurities.

• Attach the adjustable nozzle extension to the spray gun
(Figure 6).Tighten by hand.

• Position the nozzle in the low pressure mode (see “How
to Use the Adjustable Nozzle”) and squeeze the trigger
on the spray gun to relieve the air pressure caused by
turning ON the water.Water will flow out of the spray
gun in a thin stream. Continue to hold trigger until there
is a steady stream of water and no air remains in the
system.This will make it easier to pull start the engine.
Release the trigger.

• Engage the safety latch to the spray gun trigger
(Figure 7).

• Rotate the choke knob to the “Choke” position
(Figure 8).

NOTE: For a warm engine, be sure the choke knob is in
the “Run” position.

How to Use the Turbo Nozzle

The turbo nozzle rotates the high pressure stream in a
rapid circular pattern.The high pressure spray is most
effective when the tip of the nozzle extension is held
between 8 to 24 inches from the surface being cleaned.

Always start the turbo nozzle at a distance, gradually
getting closer to the surface until you get the cleaning
force you want.

WARNING! The turbo nozzle produces an

extremely high pressure spray which is capable of
removing paint and cutting holes through surfaces if
held too close.Always make sure the surface you
will clean will not be damaged by the high pressure
spray by testing in a hidden area.

NOTE:You cannot apply detergent with the turbo nozzle.

Applying Detergent with the

Adjustable Nozzle

IMPORTANT: Use soaps designed specifically for

pressure washers. Household detergents could damage the

pump.

CAUTION!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.

• Prepare the detergent solution as required by the job.

• Place the filter end of the detergent siphoning tube into
the detergent container.

CAUTION! Keep the detergent siphoning tube from

coming in contact with the hot muffler.

• 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. 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.

• Allow the detergent to "soak in" for 3-5 minutes before
washing and rinsing. Reapply as needed to prevent
surface from drying. Do Not allow the detergent to dry
on (prevents streaking).

IMPORTANT: You must flush the chemical injection
system after each use by placing the filter into a bucket of
clean water, then run the pressure washer in low pressure
for 1-2 minutes.

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 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.

Pressure Washer For Use”. Connect the water supply
and turn water on.

• Remove the nozzle extension from the spray gun.

• Start the engine according to instructions in “How To
Use Your Pressure Washer”.

• Squeeze the trigger on the spray gun and hold.

• When the water supply is steady and constant, engage
the safety latch and refasten the nozzle extension.

Check In-Line Filter

Refer to Figure 13 and service the in-line filter if it
becomes clogged, as follows:

1. Detach spray gun and nozzle extension from high

pressure hose. Detach nozzle extension from spray
gun and remove o-ring and screen from nozzle
extension. Flush the screen, spray gun, and adjustable
nozzle extension with clean water to clear debris.

2. If the screen is damaged, the o-ring kit contains a

replacement in-line filter screen and an o-ring. If
undamaged, reuse screen.

3. Place the in-line filter screen into the threaded end of

the nozzle extension. Direction does not matter. Push
the screen in with the eraser end of a pencil until it
rests flat at the bottom of the opening.Take care to
not bend the screen.

4. Place the o-ring into the recess. Push the o-ring snugly

against the in-line filter screen.

5. Assemble the nozzle extension to the spray gun, as

described earlier in this manual.

Cleaning Detergent Siphoning Tube

If you used the detergent siphoning tube, you must flush it
with clean water before stopping the engine.

• Place the detergent siphoning tube in a bucket full of
clean water.

• Slide the adjustable nozzle forward to the low pressure
position. Flush for 1-2 minutes.

• Shut off the engine.

IMPORTANT: Simply shutting OFF engine will not
release pressure in the system. When the engine has

shut down, squeeze the trigger on the spray gun to
relieve the pressure in the hose.

Nozzle Maintenance

A pulsing sensation felt while squeezing the spray gun
trigger may be caused by excessive pump pressure.The
principal cause of excessive pump pressure is a nozzle
clogged or restricted with foreign materials, such as dirt,
etc.To correct the problem, immediately clean the nozzle
using the tools included with your pressure washer and
follow these instructions:

1. Shut off the engine and turn off the water supply.

2. Detach the nozzle extension from the spray gun.Twist

the nozzle clockwise to the stream position. Using the
supplied 2mm (5/64) allen wrench, remove the nozzle
from the end of the nozzle extension (Figure 14).

3. Remove the in-line filter from the other end of the

nozzle extension.

4. Use the wire included in the kit (or a small paper clip)

to free any foreign material clogging or restricting the
nozzle (Figure 14).

8. Reconnect the water supply, turn on the water, and
start the engine.

9. Test the pressure washer by operating with nozzle in
the high and in the low positions.

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.

An O–Ring Maintenance Kit is provided with your pressure
washer. It 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.

To remove a worn or damaged o–ring:

• Use a small flathead screwdriver to get underneath the

o-ring and pry it off.

ENGINE MAINTENANCE

See the engine owner’s manual for instructions on how to
properly maintain the engine.

CAUTION! Avoid prolonged or repeated skin

contact with used motor oil. Used motor oil has
been shown to cause skin cancer in certain
laboratory animals.Thoroughly wash exposed areas
with soap and water.
KEEP OUT OF REACH OF CHILDREN. DON'T
POLLUTE. CONSERVE RESOURCES. RETURN
USED OIL TO COLLECTION CENTERS.

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:

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.

2. Shut off the engine and let it cool, then remove high
pressure and garden hoses.Disconnect spark plug wire
from spark plug.

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.

4. Use PumpSaver to treat pump.This prevents freeze
damage and lubricates pistons and seals.

NOTE: If PumpSaver is not available, 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.

5. Store unit in a clean, dry area.

LIMITED WARRANTY

SNAPPER™ OWNER WARRANTY POLICY Effective October 1, 2001

WARRANTY PERIOD*

* The warranty period begins on the date of purchase by the first retail consumer or commercial end user, and continues for the period of time
stated in the table above. "Consumer use" means personal residential household use by a retail consumer. "Commercial use" means all other uses,
including use for commercial, income producing or rental purposes. Once equipment has been used commercially, it shall thereafter be considered
to be in commercial use for purposes of this warranty. Used equipment, demonstration equipment and equipment used for prime power in place
of a utility are not warranted.Accessory parts such as guns, hoses,wands and nozzles are excluded from the product warranty.

** The gasoline engine and starting batteries are warranted solely by the manufacturers of those products.

WARRANTY REGISTRATION IS NOT NECESSARY TO OBTAIN WARRANTY ON GENERAC PORTABLE PRODUCTS
EQUIPMENT. SAVE YOUR PROOF OF PURCHASE RECEIPT. IF YOU DO NOT PROVIDE PROOF OF THE INITIAL
PURCHASE DATE AT THE TIME WARRANTY SERVICE IS REQUESTED,THE MANUFACTURING DATE OF THE
EQUIPMENT WILL BE USED TO DETERMINE THE WARRANTY PERIOD.

About your equipment warranty:

Generac Portable Products welcomes warranty repair and apologizes to you for being inconvenienced.Any Authorized Service Dealer may perform
warranty repairs. Most warranty repairs are handled routinely, but sometimes requests for warranty service may not be appropriate. For example,
warranty would not apply if equipment damage occurred because of misuse, lack of routine maintenance, shipping,handling, warehousing or improper
installation. Similarly, warranty is void if the serial number of the equipment has been removed or the equipment has been altered or modified.

If a customer differs with the decision of the Service Dealer, an investigation will be made to determine whether the warranty applies.Ask the
Service Dealer to submit all supporting facts to its Distributor for review.If the Distributor decides that the claim is justified, the customer will be
fully reimbursed for those items that are defective.To avoid misunderstandings that might occur between the customer and the Dealer, listed
below are some of the causes of equipment failure that the warranty does not cover:

Normal wear:

Outdoor Power Equipment, like all mechanical devices, needs 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 the equipment.

Installation and Maintenance:

This warranty does not apply to equipment or parts that have been subjected to improper or unauthorized installation or alteration,
misuse, negligence, accident, overloading, overspeeding, improper maintenance, repair or storage so as, in Generac Portable Products'
judgment, to adversely affect its performance and reliability.This warranty also does not cover normal maintenance such as adjustments,
fuel system cleaning and obstruction (due to chemical, dirt, carbon or lime, etc.).

Other Exclusions:

Also excluded from this warranty are wear items such as quick couplers,oil gauges, belts,o-rings, filters, pump packing, etc., pumps
which have been run without water supplied or damage or malfunctions resulting from accidents, abuse, modifications, alterations, or
improper servicing or freezing or chemical deterioration.

Warranty is available only through service dealers authorized by Generac Portable Products.This warranty does not apply to
service by any other entity.
