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 theChoke” 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.

• If the choke lever has been moved to the “Choke”
position to start the engine, gradually move it to the “Run” position as the engine warms up.
• Attach the nozzle extension to the spray gun. Tighten by hand (Figure 13).
• Select the desired quick connect nozzle and insert it into the end of the nozzle extension (see “How To Use the Nozzles”).
• Disengage the safety latch on the spray gun.
How to Stop Your Pressure Washer
• Move the throttle lever to the “Slow” position.
• Move the fuel valve to the “Off” position.
• Wait for the engine to idle down.
• Move the rocker switch 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.
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.

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.

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.

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.
