Frequently Asked Questions - 95006 Simpson

How to start the engine of the Simpson 95006 pressure washer?

Before starting, check oil and fuel levels, open the water tank valve and connect the gun. For a cold engine, set the choke to CHOKE position. Start manually by pulling the cord slowly until resistance then with a sharp pull, or electrically by turning the key to START. Let it warm up for 1-2 minutes before use.

Which nozzles to use for different surfaces?

The nozzles are color-coded: red (spot cleaning metal/concrete), yellow (intense cleaning of unpainted surfaces), green (general use), white (painted/delicate surfaces), and black (detergent application). Refer to the chart in the manual to choose the appropriate nozzle.

How to use detergent with the Simpson 95006?

Make sure the burner is off and the engine is cool. Disconnect the inlet hose from the reel from the high-pressure outlet, insert the external soap injector, then place the siphon hose into the detergent. Use the black nozzle. After use, rinse the system with clean water.

How to activate hot water on this cleaner?

Fill the burner fuel tank with #2 diesel. Start the engine, then turn the burner switch to ON. The burner ignites automatically when the trigger is pressed. To turn off, set the burner switch to OFF and let cold water run for 2 minutes.

What to do if the pump does not build pressure?

Check that the nozzle is not clogged (clean it with the provided tool), that the water inlet filter is clean, that the detergent valve is closed, and that the hose is not kinked. If the problem persists, inspect the pump valves or contact customer service.

What regular maintenance is required?

Before each use, check engine and pump oil levels, water filter, and hose condition. After 50 hours of operation, drain the pump oil. Clean nozzles regularly and lubricate fittings with lithium grease.

How to store the pressure washer for a long period?

Drain the fuel tank or add stabilizer, drain the water tank, change the engine oil, pour some oil into the cylinder through the spark plug hole, and store the trailer in a dry place out of the sun.

What are the important safety precautions?

Never use the appliance indoors (risk of CO poisoning). Wear safety glasses, ear plugs, long pants, and closed-toe shoes. Keep children and pets away. Never direct the spray at people or animals.

The burner does not ignite, what to check?

Make sure the burner switch is ON, the diesel tank is not empty, and the trigger is pressed (the burner only ignites when water is flowing). Check the fuse and fuel filter. If no spark, contact a service center.

How to prime the pump after dry start?

If the pump has run without water, immediately stop the engine. Fill the water tank, open the valve, then loosen the high-pressure outlet fitting until water flows without air. Tighten and restart. If damage has occurred, contact customer service.

WATER TANK VALVE

Located beneath the water tank, is a three-way valve. This valve allows you to control the flow of water from the tank, including draining the tank during freezing weather.

When the valve handle is perpendicular to the valve body, the valve is in the closed position (no water will flow from the tank).

Placing the valve handle parallel to the valve body, the valve is open allowing water to flow in the direction of the arrow on the valve handle. When the arrow is pointing toward the hose leading to the high-pressure pump, the tank is ready to supply water to the pump.

Placing the handle with the arrow pointing toward the open connection, the tank will now drain allowing the tank to be cleaned or in preparation for freezing weather.

The engine is shipped from the factory without oil. Running the engine without oil will result in severe engine damage and void the warranty. To avoid causing engine damage and voiding the warranty, fill the engine with the recommended oil type before starting.

NOTICE

USE CORRECT ENGINE OIL

Oil is a major factor in the performance and service life of any engine. Using the incorrect oil may damage the engine and void the warranty. To avoid causing engine damage and voiding the warranty, check and change oil as required using the correct engine oil.

1. Check oil with the trailer level and the engine off.
2. Remove the oil dipstick; wipe it clean with paper towel.
3. Insert the clean dipstick into the spout fully.
4. Remove the dipstick. The oil level should be at, but not above, the full or high mark.
5. If the oil level is low, add the recommended oil to the crankcase until the level reaches the full or high mark on the dipstick. See the engine manual for the recommended oil.
6. Place the dipstick back into the spout fully.

Diesel engine (if applicable)

Before using the pressure washer, you must fill the engine with the correct type and quantity of lubricating oil. When checking and filling the engine with oil, make sure the pressure washer trailer is sitting on a level surface.

Use the Engine Operator's manual during the following steps:

1. Remove the dipstick from the engine. While the style may differ from the one shown at the right, all will have indication marks to show the correct oil level within the crankcase.

2. The Engine Operator's Manual contains important information as to the weight of oil for your given operating conditions. Typically, SAE 15W-40 or ISO 100 engine oil will suffice for most operating conditions. If you operate in high temperatures or very dirty conditions, consult the Engine Operator's Manual for oil recommendation.

3. Fill the crankcase with the correct type and quantity of oil, DO NOT overfill. Place the dipstick into the engine, but do not screw down (where applicable). Remove the dipstick to verify the oil level. If the level is low, carefully add a small quantify of oil then check the level once again with the dipstick.

Upper Oil Limit Lower Oil Limit

1. Once the correct level is met, make sure the dipstick is tight within the engine block.

NOTICE

LOW OIL SENSOR

The low oil sensor (if equipped) will automatically stop the engine when the oil level falls below the safe limit. To avoid an unexpected shutdown, check the oil level regularly, fill to the upper limit, and always operate engine on a level surface.

Engine Fuel

Gasoline

LOOK BEFORE YOU PUMP! —— Ethanol Percentage — <10% OK NO 15% - 30% - 85%

It is imperative to use fresh (less than 30 day old) gasoline with a minimum octane rating of 87 and a maximum ethyl alcohol level of 10%.

Add fuel to the pressure washer by following these steps:

1. Check fuel with the engine off and the pressure washer trailer on a level surface.
2. Remove the fuel cap to verify the fuel level. For the fuel cap location, see the COMPONENTS LOCATION section of this manual.

3. Use clean, fresh, regular unleaded gasoline with a minimum octane rating of 87. Do not mix fuel and oil! Only use fuel with a maximum ethyl alcohol level of 10%. E15, E20 and E85 are not approved fuels. ENGINE DAMAGE MAY OCCUR BY USING THESE FUELS.

4. Do not fill the fuel tank above the maximum fuel level to allow room for use expansion.

5. Replace the fuel cap. Never run the engine or pressure washer without the fuel cap(s) installed.

NOTE: Using a fuel stabilizer (sold separately) when storing gasoline can help to prevent problems related to ethanol alcohol blended gasoline. Always follow the instructions on the bottle and mix thoroughly.

REFUELING

Gasoline is highly flammable and gasoline vapors are extremely explosive. Fire and explosions can cause severe burns and/or death. Keep gasoline away from flames, sparks, and other ignition sources. Refuel outdoors in a well-ventilated area with the engine stopped and cool. Wipe up any spilled gasoline and allow engine to dry before starting. Keep a fire extinguisher handy while refueling. Do not operate engine with leaks in the fuel system. Do not store gasoline near other flammable materials.

OLD GASOLINE

Old gasoline can create deposits that clog fuel systems causing hard starting and poor performance. Damage caused by old fuel is not covered by warranty. To minimize deposits, avoid old fuel related performance issues, and prevent costly repair work, do not use gasoline that is older than 30 days.

ALCOHOL BLENDS

Using gasoline with an alcohol blend greater than 10% (E10) will damage the engine. Damage caused by using an alcohol blend of 15% (E15), 85% (E85), or any other alcohol blend higher than 10% (E10) is not covered under warranty. To avoid engine damage caused by an alcohol blend that is too high, use gasoline with 10% (E10) alcohol or lower.

GASOLINE ADDITIVES

The use of fuel system cleaning additives can damage the engine and fuel systems. Damage caused by the use of fuel system cleaning additives is not covered by warranty. To avoid engine and fuel system damage, do not use any fuel system cleaning additives.

GASOLINE STORAGE

It is important to prevent gum deposits from forming in essential fuel system parts, such as the carburetor, fuel filter, fuel hose or tank during storage. Alcohol-blended fuels attract moisture, which leads to separation and formation of acids during storage. Acidic fuel and gum deposits can damage the engine's fuel system while in storage. Damage caused by the use of old, stale, or contaminated fuel are not covered under warranty.

Diesel Engine

Add fuel to the pressure washer by following these steps:

1. Check fuel with the engine off and the pressure washer trailer on a level surface.
