Getting To Know Your Pressure Washer

Pressure Washer

How do I start my pressure washer?

1. Make sure you have gas and oil in the engine. The engine DOES NOT COME FILLED WITH OIL.

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

3. Open the fuel shutoff valve by turning the knob counterclockwise until it stops.

4. Close the choke (if engine is cold) by moving the choke ring fully to the right.

5. Set the shut off switch to “ON.”

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

What type of oil do I use?

ENGINE DOES NOT COME FILLED WITH OIL: See Page 10 for engine oil types, quantities, and oil changing instructions.

Pump: The pump comes filled with the correct amount of oil and should not need changing or filling.

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 15º (yellow) spray tip inserted into the end of the lance (See Page 8)?

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

How do I get high pressure?

• For high pressure, insert the 15º (yellow) spray tip into the end of the lance (See Page 8).

How do I get the soap suction to work?

1. Attach clear plastic tube to barb on pump (see Figure 2 on page 5).

2. Put the other filter end of the clear tube into the detergent container.

3. Install the black spray tip to apply low pressure detergent.

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

Detergents “bounce” off cleaning surfaces as fast as they are applied. The pressure washer’s features allow for a detergent to be drawn while in low pressure mode only. By applying detergent at low pressure, the effect of “bouncing” is reduced. Also, detergents are only effective when time is allowed for them to work on the surface of whatever is being cleaned. After applying the detergent, wait 1-3 minutes while it works, and then proceed to 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.

5. Follow proper storage and winterizing instructions found on page 9.

What do I do if I’m missing a part?

the trigger on the gun, pull the starter rope rapidly and firmly (See Figure 10). Continue holding the rope as it returns. Repeat these steps until the engine starts.

When pulling the starter rope,

make sure to keep your hand

and arm clear of the engine and cart components.

Never let the starter 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.

Spray the cleaning surface with water to clear off any dirt or grime that may have collected on the surface. Doing so allows the detergent to attack the deep down dirt that has worked its way into the cleaning surface.

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 (see Figure 11).

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

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.

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

If water has frozen 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.

2. Check fuel level. Add unleaded gasoline (rated 86 octane or

higher) as required

DO NOT refuel a hot engine.

Refueling a hot engine could cause a fire. Use only fresh, clean regular or unleaded gasoline. Close the fuel shutoff valve during refueling.

3. Attach a garden hose to the inlet side of the pump and

connect it to the water supply. Use a hose with an internal diameter (I.D.) of 5/8 inch (1.58 cm) and a length of 50 ft. (15 m) or less.

Some local plumbing 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 5 gpm (19 lpm).

4. Turn the water supply ON.

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 smoothly from the tip

indicating that all air is purged from the system. Lock the trigger safety latch.

6. Open the fuel valve by turning the knob counterclockwise

until it stops. Close the choke (if engine is cold) by moving the choke ring fully to the right. Turn the ignition switch to “ON”.

7. Start the engine. Unlock the trigger safety latch on the gun

(See Figure 9). Grasp the starter rope and brace one foot on the chassis. Point the gun in a safe direction. While squeezing

DISTANCE FROM CLEANING SURFACE

The distance between the spray tip and the cleaning surface is another factor that affects the impact force of the water. The impact force of the water increases as the spray tip 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 spray tip angle to the cleaning surface and the distance from the cleaning surface and by changing the spray tip. NEVER use a narrow high impact stream on a surface that is susceptible to damage. Avoid spraying windows with a narrow high impact stream. Doing so may break the window. The most sure way to avoid damaging surfaces is to follow these steps:

1. Before triggering the gun, make sure the quick connect

tip you are using is appropriate for the application.

2. Place the spray tip approximately 4-5 feet (1,22-1,52 m)

away from the cleaning surface. Then hold the lance and spray tip 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.

NOTE: Use only detergents formulated for pressure washers.Test detergent in an inconspicuous area before use.

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 12% (1 to

8).

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

3. Install 65º (Black) Low Pressure Detergent Tip in the quick connect fitting on the end of the lance.

NEVER replace quick connect tip

when gun is triggered. Always engage trigger lock on gun before removing or installing quick connect tips.

GENERAL CLEANING TIPS

1. Apply the detergent so that it thoroughly covers the

cleaning surface. Apply the detergent from bottom to top to prevent the detergent from 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.

2. Replace black 65º quick connect tip with the yellow 15º tip

and complete final rinse.

NEVER replace quick connect tip

when gun is triggered. Always engage trigger lock on gun before removing or installing quick connect tips.

3. NOTE: After using detergents, flush the suction system by

placing the detergent suction tube into a bucket of clean water and running unit with black 65º tip flushing clean water from tank through the pump.

4. Detergent Application

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

Red – 0° – Maximum Duty* Yellow – 15° – Heavy Duty Green – 25° – General Duty* White – 40° – Light Duty* Black – 65° – Low Pressure Detergent

* = Not Included

Figure 11 - Optimum angle to cleaning surface

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 while standing several feet from the surface. Slowly move closer to the object you are cleaning until you find the most effective cleaning technique.

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.

To reduce the risk of bodily injury or property damage, always follow this procedure whenever spraying is stopped, when work is completed, and before checking or repairing any part of the system.

1. Engage the trigger safety latch.

2. Turn the unit off.

3. Shut off the water supply.

4. Disengage the trigger safety latch and trigger the gun to relieve pressure.

5. Re-engage the trigger safety latch.

6. When checking or repairing unit, remove the ignition cable from the spark plug.

7. Before overnight storage, long term storage, or transporting unit, disconnect the water supply and turn off the fuel supply valve.

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 water supply off

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

NEVER disconnect 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.
