HOW TO USE YOUR

PRESSURE WASHER

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.

• This pressure washer requires a water source that flows at least 2 gallons per minute. Do not attempt to siphon water from a non-pressurized con-

tainer. Place the pressure washer close enough to an outside water source so that no more than 50' of garden hose is needed.

• 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 the water on all the way.

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.

• Squeeze the trigger on the spray gun to relieve air pressure caused by turning ON the water. Water will spew out the gun in a thin stream. Continue to hold trigger until you have a steady stream of water and no air remains.This will make it easier to pull start the engine. Release the trigger.

Figure 10 — Squeeze trigger to relieve water pressure, release trigger and turn the safety latch ON.

Safety Latch ON

• Apply the safety latch to the spray gun trigger

(Figure 10).

• 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, disengage the spray gun safety latch, squeeze the trigger to relive water pressure, re-engage the spray gun safety latch, 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.

Note: A small amount of water will squirt out when you release the pressure.

How to Use the Adjustable

Nozzle and Adjust Pressure

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.

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.

• Located on the side of the pump is a pressure control knob. You can increase and decrease the pressure of the spray by turning the knob clockwise or counterclockwise respectively (Figure 12).

Figure 11 — Using the adjustable nozzle.

Figure 12 — Pressure control knob.

Pressure Control Knob

• Point the nozzle toward the ground and press the trigger to test the pattern.

• 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.

• 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.

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 hook of the wireform on the handle as shown (Figure 13).

• Place small filter end of the chemical injecting tube into the detergent container.

Figure 13 — Insert the small filter into container of cleaning solution.

• 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 engine.

• Apply detergent to a dry surface, starting from the bottom and working up to avoid streaking.

• Allow the detergent to soak in for 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.

H i g h P r e s s u r e W a s h e r

11

CAUTION: Keep the plastic injector 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 so as 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 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 siphon from bottle.

Automatic Cool Down System

(also known as 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

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 warranty, operator must maintain high pressure 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 the engine owner’s 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.

BEFORE EACH USE

• Check engine oil level.

• Check water inlet screen for damage.

• Check high pressure hose for leaks.

• Check detergent inlet hose and filter for damage.

• Check gun and wand assembly for leaks.

PRESSURE WASHER

MAINTENANCE

Check and Clean Inlet Screen

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

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.

Check Detergent Hose

Examine the filter on the detergent hose and clean if clogged. Hose should fit tightly on barbed fitting.

Examine hose for leaks or tears. Replace the filter or hose if either is damaged.

Check Gun and Wand

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 wand extension from the gun.

• Squeeze the trigger on the gun and hold.

To remove any contaminants from the pump, follow these steps:

Cleaning Chemical Injector Hose

If you have used the chemical injector hose you must flush it with clean water before stopping the engine.

• Place the small filter end of the chemical injection tube in a bucket of clean water.

• Slide the adjustable nozzle forward.

• Squeeze the spray gun trigger for five minutes to flush the chemical injection tube.

• 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.

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 wand 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 17 — Removing and cleaning nozzle.

• Remove additional debris by back flushing water supply through wand extension (Figure 18). Back flush between 30 to 60 seconds. Turn nozzle extension to stream spray and move nozzle forward and backward while flushing.

Figure 18 — Backflushing the nozzle.

• Reinstall nozzle into the wand extension. DO NOT over–tighten.

• Reconnect the nozzle extension to the spray 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.

PREPARING THE UNIT FOR

STORAGE

Water should not remain in the unit for long periods of time. Sediments of 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 chemical injection tube by placing the injector filter into a pail of clean water while running pressure washer and squeezing the spray gun trigger with the adjustable nozzle in low pressure mode.

Flush for five minutes.

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

3.Place throttle lever in STOP position.

CAUTION: Be sure lever is in “STOP” position before you continue. If you start engine without proper water supply connected, you can damage pump.

4.Empty the pump of all pumped liquids by pulling recoil handle about 6 times. This should remove most of the liquid in the pump.

NOTE: To protect unit from freezing temperatures, draw windshield washer fluid into pump by pouring windshield washer fluid into a 3-foot section of garden hose connected to inlet adapter and pulling recoil handle twice.

5.Store 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.

During said warranty period, GENERAC will, at its option, repair or replace any part which, upon examination by GENERAC or GENERAC 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, 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 PARTICU-

LAR 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 must be presented.
