Frequently Asked Questions

How do I start my pressure washer?

1.Make sure you have gas and oil in the engine.

2.Turn the water on, then trigger the gun to make sure the water will flow smoothly out of the nozzle or tip.

3.Put the engine throttle control in the “Fast/Start” position. Set the fuel shut off switch to “ON.” Set the on/off switch to “ON” (if applicable).

4.Set the choke to “ON.”

5.Pull the trigger (to relieve any back pressure in the pump) while pulling the starter cord.

6.If the engine does not start after three tries, repeat Step 5 (See Page 6) or see Troubleshooting Section (Pages 12-13).

What type of oil do I use?

The pump on the horizontal pressure washer comes filled with the correct amount of oil and should not need filling. See Page 11 for pump oil types and quantities. THE ENGINE DOES NOT COME FILLED WITH OIL. See Page 11 for engine oil types and quantities. Refer to Pages 10 and 11 of this manual and also refer to the included engine owner’s manual for oil changing instructions.

Why don’t I have any water pressure?

Is the water hose attached to the pressure washer?

Is the water turned on?

Check for any kinks, leaks, or blockage in the hoses, fittings, or the nozzle.

Is the adjustable nozzle in the low psi position? If so, move it into the high psi position (See Page 8).

Is the inlet filter screen free of debris? Check and remove debris if needed.

Is the quick connect tip in place? (See Page 4.)

How do I get high pressure?

For high pressure, move the nozzle into the high psi position (See Page 8).

For units with quick connect tips: use any color tip with the exception of black. Black tip is used for low pressure detergent application.

How do I get the soap suction to work?

1.Attach clear plastic tube to brass barb on pump (See Page 4).

2.Insert filter end of clear plastic tube into detergent liquid.

3.Move the nozzle into the low psi position (See Page 8).

4.For quick connect lance, use black detergent tip (see Page 8).

Why doesn’t the pressure washer apply detergents with high pressure?

The reason you don’t apply detergents with high pressure is that the detergents “bounce” off the cleaning surface as fast as you apply them. Detergent is only effective when you allow it time to work on the surface of whatever you are cleaning. You can only apply detergent at low pressure, wait 1-3 minutes to allow it to work, and rinse the surface with high pressure.

What maintenance do I need to perform on my pressure washer?

1.After turning off the pressure washer and the water, depressurize the hose by triggering the gun.

2.Remove the garden hose and high pressure hose from the pump.

3.Pull the start rope slowly five times to purge water from the pump. This will help protect the pump from damage.

4.Do not store your pressure washer in an area where the temperature will drop below 32˚ F unless pressure washer is properly winterized (see Page 9).

Pressure Washers

Operation

1. Surface Preparation

The following cleaning procedure will help you organize your cleaning task and ensures that you will achieve the best results in the shortest amount of time. Remember to use the spraying / cleaning techniques mentioned in the following section.

Before starting a pressure washer cleaning job, prepare the surface you intend to clean. Clear furniture from the area and make sure that all windows and doors are closed tightly. Also, protect all plants and trees near the cleaning area with a drop cloth. A covering ensures that your plants won’t be sprayed by the detergents.

2. Start Up

ALWAYS use this start up procedure to ensure that the unit is started safely and properly.

If water has frozen NOTICE in the pressure

washer, thaw the pressure washer in a warm room before starting. DO NOT pour hot water on or into the pump; internal parts will be damaged.

1.Check engine oil levels. Add oil as necessary.

3.Attach a garden hose to the inlet side of the pump and connect it to the water supply. Use a hose with an I.D. of 5/8” and a length of 50 ft. (15 m) or less.

Some local plumb- NOTICE ing codes require

backflow prevention when connecting to a fresh water supply. Install a backflow preventer upstream from the pump if necessary.

a.If inlet water pressure is over 100 psi, install a regulating water valve at the garden hose connection.

b.Do not exceed 100˚ F (38˚ C) inlet water temperature.

NOTE: The inlet water supply must have a minimum flow rate of 8 gpm (30 lpm).

4. Turn the water supply ON.

NOTICE

Never run the unit

dry. Be sure the

 

water supply is completely turned on before operating the unit.

5.Trigger the gun until water sprays from the tip indicating that all air is purged from the system. Set the trigger safety latch.

6.a. Honda Engines: Open the fuel shutoff valve by pushing the shut off valve lever to the right. Close the choke (if engine is cold) by moving the choke lever fully to the left. Move the throttle, if equipped, fully to the left to the Run or Rabbit position. If equipped, turn on the on/off switch to the “on” position.

b.Briggs and Stratton Engines: Vanguard Series: Open the fuel shutoff valve by rotating lever to the vertical position. Close the choke (if engine is cold) by moving the choke lever fully to the left. Move the throttle, if equipped, fully to the left to the Run or Rabbit position. If equipped, turn on the on/off switch to the “on” position.

Intek Series: Open the fuel shutoff valve by rotating lever to the horizontal position. Close the choke (if engine is cold) by moving the choke lever fully to the right. Move the throttle, if equipped, fully to the right to the Run or Rabbit position. If equipped, turn on the on/off switch to the “on” position.

c.Robin Engines: Open the fuel shutoff valve by turning the lever to the downward position. Close the choke (if the engine is cold) by moving the choke lever fully to the left. Move the throttle fully to the left to the Run or Rabbit position. If

equipped, turn on the on/off switch to the “on” position.

7.Start the engine.

If the engine is cold, completely close the engine choke.

If the engine is warm, leave the choke open or just partially closed. Unlock the trigger safety latch on the gun. Grasp the starter rope and brace one foot on the chassis. While squeezing the trigger on the gun, pull the starter rope rapidly and firmly. Continue holding the rope as it returns. Repeat these steps until the engine starts. In cool weather, the choke may have to be kept closed for 10 to 30 seconds to keep the engine running. Otherwise, open the choke as soon as the engine starts.

When pulling the ! CAUTION starter rope, make

sure to keep your hand and arm clear of the engine and cart components.

Never let the starter NOTICE rope return by itself.

Doing so could jam the recoil system.

8.If the engine does not start after two or three pulls or if the rope is hard to pull, squeeze the gun trigger to release the pressure that has built up in the high pressure hose. Repeat Steps 7 and 8 until the engine starts.

3. Initial High Pressure Rinse

After the engine starts, trigger the gun 3 to 5 times to get any trapped air out of the system. After the spray becomes constant, you may need to adjust the pressure or the spray fan angle for the optimal cleaning performance needed (see pages 7, 8 and 9 for cleaning techniques).

PRESSURE ADJUSTMENT

Some units have a pressure adjustment knob located on the pump (see Figure 10). Turn the knob clockwise to increase the pressure. Turn the knob counter clockwise to decrease the pressure. Do not try and force the knob to turn. The knob may already be at either the lowest or highest setting.

www.chpower.com

6

Operation (Continued)

If there is not a plastic adjustment knob located on the pump (See Figure 10), then the pressure cannot be adjusted. The only way to adjust the pressure is to move closer or further away from the cleaning surface and adjust the spray fan angle as shown in the next section.

Counterclockwise:

Lower pressure

Clockwise:

Higher pressure

Figure 10 - Camshaft pump pressure adjustment

ADJUSTING THE SPRAY FAN ANGLE

Your unit is either equipped with a adjustable fan nozzle or quick connect tips that have a range of spray fan angles.

If equipped with the adjustable fan nozzle, the spray end of the lance can be rotated to have a 0o narrow high impact stream to a 60o wide fan spray (See Figure 11).

Detergent

A narrow stream has high impact force on the cleaning surface and results in maximum deep cleaning in a concentrated area. However, this narrow high impact spray can damage some surfaces, so use it cautiously.

A wide fan pattern will distribute the impact of the water over a larger area resulting in excellent cleaning action with reduced risk of surface damage. Clean large surface areas quickly using a wide fan pattern.

Figure 11 - Adjusting nozzle for fan pattern

If equipped with the quick connect tips, the tips can be switched out from a 0o narrow high impact stream to a 65o wide fan spray.

The color of the tip shows what spray angle it is:

Red – 0o – Maximum Duty Yellow – 15o – Heavy Duty

Figure 13 - Narrow high impact stream

Figure 14 - Wide fan pattern

ANGLE TO THE CLEANING SURFACE

When spraying water against a surface, you can generate maximum impact by striking the surface head on. However, this type of impact can cause dirt particles to embed in the surface and can prevent the desired cleaning action.

The optimum angle for spraying water against a cleaning surface is 45 degrees.

Spray water against a surface at a 45 degree angle to achieve the most beneficial impact force and to efficiently remove debris.

Figure 15 - Optimum angle to cleaning surface

DISTANCE FROM CLEANING SURFACE

The distance between the spray nozzle and the cleaning surface is another factor that affects the impact force of the water. The impact force of the water increases as the nozzle is moved closer to the surface.

HOW TO AVOID DAMAGING SURFACES

Damage to cleaning surfaces occurs because the impact force of the water exceeds the durability of the surface. You can vary the impact force by controlling the nozzle’s fan pattern, the nozzle’s angle to the cleaning surface, and the nozzle’s distance from the cleaning surface. Never use a narrow high impact stream or a Turbo/rotary nozzle on a surface that is susceptible to damage. Avoid spraying windows with a narrow high impact stream or turbo nozzle. Doing so may break the window. The most sure way to avoid damaging surfaces is to follow these steps:

Pressure Washers

Operation (Continued)

1.Before triggering the gun, adjust the nozzle or quick connect tip to a wide fan pattern.

2.Place the nozzle approximately 4-5 feet away from the cleaning surface. Then hold the nozzle at a 45 degree angle to the cleaning surface. Trigger the gun.

3.Vary the fan pattern spray angle and the distance to the cleaning surface until optimum cleaning efficiency is achieved without damaging the surface.

TURBO NOZZLE (NOT INCLUDED WITH ALL MODELS)

A turbo nozzle, sometimes referred to as a rotary nozzle, can significantly reduce cleaning time. The turbo nozzle combines the power of a narrow high impact stream with the efficiency of a 25 degree fan pattern. The turbo nozzle swirls a narrow high impact stream into a cone shape to clean a larger area.

Since a turbo nozzle NOTICE uses a narrow high

impact stream, only use a turbo lance in applications where the cleaning surface cannot be damaged by narrow high impact spray. The turbo nozzle is NOT adjustable and cannot be used to apply detergent.

4. Detergent Application

USE THE INSTRUCTIONS APPROPRIATE FOR MODEL PURCHASED

NOTE: Use only detergents formulated for pressure washers.

NOTE: Test detergent in an inconspicuous area before use.

Never slide the NOTICE nozzle from low to

high pressure or from high to low pressure when the gun is triggered.

 

Never replace quick

is triggered.

 

DETERGENTS

The use of detergents can dramatically reduce cleaning time and assist in the removal of difficult stains. Many detergents are customized for pressure washer use on specific cleaning tasks. Pressure washer detergents are as thick as water. Using thicker detergents – like dish soap – will clog the chemical injection system

and prevent the application of the detergent.

Once applied to a cleaning surface, detergents take time to break down dirt and grime. Detergents work best when applied at low pressure.

You can effectively clean surfaces by combining the chemical action of detergents with high pressure rinses. On vertical surfaces, apply the detergent starting at the bottom and work your way upward. This method prevents the detergent from sliding down and causing streaks. Begin high pressure rinsing at the bottom and work your way upward. On particularly tough stains, use a brush in combination with detergents and high pressure rinsing.

1.Follow manufacturer’s label directions for mixing correct concentrations of soap/detergents. The soap detergent to water ratio through the pump is approximately 10% (1 to 10).

2.Insert the filter end of the clear plastic detergent tube into the detergent container.

3a. Place hand around the 3.5” spraying end section of the lance (the section

that turns from left to right). Pull firmly and quickly away from you. (NOTE: Do not adjust lance while spraying.) The lance will extend 1/2” and be in low pressure (See Figure 18). Soap can only be drawn in low pressure.

3b. For units with quick connect tips: use the black 65o quick connect spray tip (See Figure 16).

4.If equipped, adjust the detergent injection flow by turning the collar of the injector. Turning collar clockwise decreases flow of detergent and turning collar counter clockwise increases detergent flow (See Figure 17).

! WARNING

Operation (Continued)

sliding down and streaking. Wait a couple of minutes for the detergent to break down the dirt and grime. Use a brush to lightly scrub heavily soiled areas. Never allow the detergent to dry on the cleaning surface.

2a. To rinse or to return the nozzle to high pressure, release the trigger and slide the nozzle to the high pressure setting.

2b. For units with quick connect tips: replace black 65o tip with another color tip.

Never make the NOTICE nozzle pressure

adjustment when the gun is triggered. Adjusting the high-low nozzle when the gun is triggered can result in damage to the seals in the nozzle.

Never replace quick ! WARNING connect tip when

gun is triggered.

3.After using detergents, flush the suction system by placing the detergent suction tube into a bucket of clean water.

5.Cleaning Power

You can control the cleaning power of your pressure washer in two ways:

1.Adjust the spray pattern at the nozzle. Choose the widest pattern possible for spraying when starting the job and adjust the pattern to a narrower angle until you find a suitable pattern.

2.The easiest way to regulate the cleaning power of your pressure washer is by changing the distance from the surface you are cleaning. Begin spraying with a wide fan pattern while standing several feet from the surface. Slowly move closer to the object you are cleaning, adjusting the spray pattern as necessary, until you find the most effective cleaning technique.

NOTE: Some units also may have a regulator knob on the pump that can adjust the pressure (if so equipped).

6. Final Rinse

The final rinse should start at the bottom and work upward. Make sure that you thoroughly rinse the surface and that you remove all detergent.

7. Shutdown

1.Be sure all detergent is flushed from system.

2.Turn the engine OFF.

3 Turn the water supply OFF.

4.After the engine and water supply are turned off, trigger the gun to depressurize the system.

NEVER turn the NOTICE water supply off

before turning the engine/motor off. Serious damage could occur to the pump and/or engine/motor.

NEVER disconnect ! CAUTION the high pressure

discharge hose from the machine while the system is pressurized. To depressurize, turn engine/motor off, turn water supply off and squeeze gun trigger 2-3 times.

5.After each use, wipe all surfaces of the pressure washer with a clean, damp cloth.

Do not store the pressure washer outdoors.

Do not store the pressure washer where it might freeze unless it has been properly winterized (See page 9, third column).

8. Storage

LONG TERM STORAGE INSTRUCTIONS (MORE THAN 30 DAYS IN STORAGE)

1.Remove fuel from the tank and run the pressure washer in a normal operating mode until the engine stops from a lack of fuel. Normal operating mode means actually spraying water from the gun while the engine is running.

TIPS FOR EXTENDING THE LIFE OF YOUR PRESSURE WASHER

1.Never operate the unit without water.

2.Your pressure washer is not meant to pump hot water. Never connect your pressure washer to a hot water supply as it will significantly reduce the life of the pump.

3.Running the unit for more than one minute without spraying water causes heat to build up in the pump. Running the unit without

spraying water can damage pump components.

4.Release the trigger prior to switching the lance between high and low pressure. Failure to do so may reduce the life of the o-rings in the lance.

Maintenance

Observe regular maintenance intervals to ensure maximum performance and life from the pressure washer. Refer to the schedule for recommended maintenance. If you operate the pressure washer in dusty conditions, perform maintenance checks more often.
