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, 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 3.0 gallons per minute. Do not attempt to siphon water from a non-pressurized

container. 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 valve on all the way.

IMPORTANT: Do not run the pump without the water supply connected and turned on. You must follow this caution or the pump will be damaged.

• Turn fuel shut-off valve 1/4 turn to OPEN position.

• Move choke control to CHOKE position.

• Move throttle control to FAST position.

• Push RUN/STOP switch to RUN position.

Note: For a warm engine, do not choke.

• Squeeze the trigger on the spray gun to relieve water pressure caused by turning on the water.

Water will spew out of the gun in a thin stream.

Continue to hold the 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.

• Apply the safety latch to the spray gun trigger

(Figure 9).

Figure 9— Safety Latch.

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. Repeat if necessary with choke off and throttle control in

FAST. Operate engine with choke in RUN and throttle in FAST position.

If after 3 pulls the engine fails to start, disengage the spray gun safety latch, squeeze the trigger to relieve water pressure, re-engage the spray gun safety latch and pull the recoil starter handle rapidly (Max. 3 pulls).

How to Stop Your Pressure

Washer

• Move throttle control to SLOW position.

• Push RUN/STOP switch to STOP position.

• Turn fuel shut-off valve 1/4 turn to CLOSED 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 Dual Lance 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 pressure and apply detergent or any other cleaning chemicals.

IMPORTANT: You must attach all hoses and turn

on the water source fully before you start the engine.

Starting the engine without all the hoses connected and without the water turned on will damage the pump.

DANGER! Never put hands in front of nozzle.

• 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 10). The unit has been set to maximum at the factory.

Figure 10 — Pressure control knob.

Pressure Control Knob

• Point the nozzle in a safe direction and squeeze the trigger to test the pressure. Be careful not to spray your feet.

• For most effective cleaning, keep the spray nozzle between 8 to 24 inches away from cleaning surface.

• If you get spray nozzle too close, especially using high pressure, you may damage the cleaning surface.

• Do not get closer than 8 inches when cleaning tires.

Applying Detergent

IMPORTANT: Use soaps designed specifically for

pressure washers. Household detergents could damage the pump.

To apply detergent follow these steps:

• Turn the valve on the dual lance to low pressure.

• Prepare the detergent solution as required by the job.

• Hang the detergent solution on the J hook on the handle.

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

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 the ASSEMBLY section), and start engine.

• Apply the 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. Reapply detergent to prevent surface from drying.

• For washing, start at lower portion of area to be washed and work upward, using long, even, overlapping strokes.

CAUTION: Keep the plastic chemical injecting 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:

• Remove the chemical injector hose from the chemical bottle to stop detergent from flowing. Spray until the detergent has cleared form the gun.

• Keep the spray gun a safe distance from the area you plan to spray.

• 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 top of 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. 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, clean or replace the air filter and check the gun and dual lance 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 dual lance 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 Chemical Injecting Tube

Examine the filter on the chemical injecting tube and clean if clogged. The tube should fit tightly on barbed fitting. Examine the tube for leaks or tears. Replace the filter or tube if either is damaged.

Check Gun and Dual lance

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 dual lance from the gun.

• Squeeze the trigger on the gun and hold.

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

• Set up the pressure washer as described in the

ASSEMBLY section, and connect the water supply.

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

• Remove the dual lance from the spray gun.

• Start the engine according to instructions in OPER-

ATION section.

• Squeeze the trigger on the spray gun and hold.

• When the water supply is steady and constant, engage the safety latch and refasten the dual lance.

Cleaning Chemical Injecting Tube

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

To clean the chemical injector hose:

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

• Open the chemical valve handle fully on the lance by turning it counterclockwise. This puts the gun in low pressure.

• Squeeze the spray gun trigger for 1-2 minutes to flush the chemical injector hose.

• 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

If the nozzle on the dual lance 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 nozzle.

If the 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.

• Press trigger to relieve pressure.

• Separate the dual lance from the spray gun.

• Use the wire included in the kit or a small paper clip to free the foreign materials clogging or restricting the nozzle (Figure 11).

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 the chemical injecting tube by placing the injector filter into a pail of clean water while running pressure washer and squeezing the spray gun trigger with the dual lance in low pressure mode.

Flush for 1-2 minutes.

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

3.Place Run/Stop Switch in STOP position.

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

NOTE: To protect the unit from freezing temperatures, draw antifreeze fluid into pump by pouring antifreeze fluid into a 3-foot section of garden hose connected to the inlet adapter and pulling the recoil handle twice. Use non-alcohol, RV antifreeze only.

5.Store in a clean, dry area.

STORING THE ENGINE

All transportation costs under warranty, including return to the factory if necessary, are to be borne by the purchaser and prepaid by the purchaser.

DAMAGES UNDER ANY AND ALL WARRANTIES IS EXCLUDED, EVEN IF SUCH DAMAGES ARE A

DIRECT RESULT OF GENERAC’s NEGLIGENCE.
