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 Engine

The best way to start your pressure washer for the first
time is to follow these instructions step–by–step. This
starting information also applies if 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
3.9 gallons per minute or more.

• Make sure the unit is in a level position.

• Check that the high pressure hose is connected to the

spray gun and to the pump. See “Preparing Pressure
Washer for Use” on page 5.

• Connect the garden hose to the water inlet on the

pressure washer pump and 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 to relieve the air

pressure caused by turning ON the water. Water will
discharge from the spray gun in a thin stream. Hold the
trigger until a steady stream of water appears. This will
make it easier to pull start the engine. Release the
trigger.

• Apply the safety latch to the spray gun trigger (Figure 8).

• Move the fuel valve to the “On” position (Figure 9).

• Move the throttle lever to the “Fast” position, shown

on engine as a rabbit (Figure 10).

• To start a cold engine, move the choke lever to the

Choke” position. To restart a warm engine, leave
the choke lever in the “Run” position (Figure 11).

• Set the rocker switch to the “On” position (Figure 12).

• Grasp starter grip and pull slowly until you feel some

resistance. Then pull cord out with rapid full arm stroke.
Let rope return slowly. Do Not let rope “snap back”
against starter.

the system. Squeeze trigger on the spray gun to
relieve pressure in the hose.

How to Use the Nozzles

CAUTION!

Never exchange nozzles without

locking the safety latch on the trigger.

The quick–connect on the nozzle extension allows you to
switch between five different nozzles. The nozzles vary the
spray pattern as shown below (Figure 14).

Follow these instructions to change nozzles:

• Engage the safety latch on the spray gun.

• Pull back the collar on the quick–connect and pull the

current nozzle off. Store the nozzle in the space provided
on the handles storage panel.

NOTE: For a more gentle rinse, select the white 40° or
green 25° nozzle. To scour the surface, select the yellow
15° or red 0° nozzle. To apply chemical, select the black
nozzle.

• Pull back on the collar, insert the new nozzle and release

the collar. Tug on the nozzle to make sure it is securely
in place.

• For most effective cleaning, keep the spray nozzle

Cleaning and Applying Chemical

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.

IMPORTANT: Use soaps designed specifically for
pressure washers. 
Household detergents could damage
the pump.

To apply detergent follow these steps:

• Review the use of the nozzles.

• Prepare the detergent solution as required by the

manufacturer.

• Place the chemical injection siphon/filter into the

detergent container.

CAUTION!

Keep the chemical injection tube from

coming in contact with the hot muffler.

• Make sure the black nozzle is installed.

NOTE: Detergent cannot be applied with the high
pressure nozzles (White, Green, Yellow, or Red).

• 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 and 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. Do Not allow the
detergent to dry on (prevents streaking).

• Allow the detergent to soak in between 3–5 minutes

before washing and rinsing. Reapply as needed to prevent
surface from drying.

Pressure Washer Rinsing

WARNING!

Be extremely careful if you must

use the pressure washer from a ladder, scaffolding
or any other relatively unstable location. Hose
water pressure builds as you climb. When you press
the trigger, the recoil from the initial spray can be
very strong. The high pressure spray could cause
you to fall if you are too close to the cleaning
surface.

After you have applied detergent, scour the surface
and rinse it clean as follows:

• Apply safety latch to spray gun.

• Remove the black chemical nozzle from the nozzle

extension.

• Select and install the desired high pressure nozzle

following the instructions “How to Use the Nozzles” on
page 9.

• Keep the spray gun a safe distance from the area you

plan to spray.

• Increase or decrease spray pressure by turning the

pressure control knob counterclockwise or clockwise
respectively (Figure 15). Use lower pressure to wash
items such a as a car or boat. Use higher pressure to
strip paint and degrease driveways.

• Apply a high pressure spray to a 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 the top of the area to be rinsed, working down

with same overlapping strokes as you used for cleaning.

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. At this temperature, the system
engages and cools the pump by discharging the warm
water onto the ground. 
This system prevents internal
damage to the pump.

PRESSURE WASHER

MAINTENANCE

Check and Clean Inlet Screen

Examine the screen on the water inlet. Clean it if the
screen is clogged or replace it if screen is damaged.

Check High Pressure Hose

The high pressure hose can develop leaks from wear,
kinking, or abuse. Inspect the 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 the hose immediately.

WARNING!

Never repair a high pressure hose.

Replace it with another hose that exceeds the
maximum pressure rating of your pressure washer.

Check Detergent Siphoning Tube

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.

Cleaning Detergent Siphoning Tube

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

• Place the chemical injection siphon/filter in a bucket full

of clean water.

• Attach the black low pressure nozzle.

• 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.

Check Gun and Nozzle Extension

Examine the hose connection to the spray gun and make
sure it is secure. Test the trigger by pressing it and making
sure it springs back into place when you release it. Put the
safety latch in the on position and test the trigger. You
should not be able to press the trigger.

Check In-Line Filter

Refer to Figure 16 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.

Shut off the engine and turn off the water supply.

2.

Remove the nozzle from the end of the nozzle
extension (Figure 17).

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 17).

5.

Using a garden hose, remove additional debris by back
flushing water through the nozzle extension
(Figure 18). Back flush between 30 to 60 seconds.

6.

Reinstall the nozzle and in-line filter into the nozzle
extension. Do Not overtighten the nozzle with the
allen wrench.

7.

Reconnect the nozzle extension to the spray gun.

8.

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

9.

Test the pressure washer by operating with each of the
Quick Connect nozzles.

O–Ring Maintenance

Through the normal operation of your pressure washer,
o–rings, which keep the connections of the hoses and spray
gun tight and leak–free, 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. Flush for one to two minutes.

2.

Shut off the engine and let it cool, then remove all
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.

STORING THE ENGINE

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

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.

To locate your nearest authorized Generac Portable Products Service Dealer, look at our dealer locator map on
www.generac-portables.com or call 1-877-544-0982. To speak with a Customer Service representative, call 1-800-317-7833.
