Frequently Asked Questions - 95122 Simpson

How to start the pressure washer?

Before starting, check engine oil, fill the water tank, and open the valve. Make sure the gun is connected. Turn on the ignition, open the fuel valve, and for a cold engine, pull the choke. Pull the starter cord (or turn the key for electric start). Let it warm up for 1-2 minutes before use.

What type of engine oil to use?

Use SAE 10W-30 API SG or newer oil for single-cylinder gasoline engines. For diesel engines, use SAE 15W-40 or ISO 100. Consult the engine manual for specific recommendations.

How to use hot water?

Start the engine, then turn the burner switch to ON. The burner ignites when you squeeze the trigger. Make sure the burner fuel tank is filled with #2 diesel. Release the trigger to turn off the burner.

How to clean clogged nozzles?

Stop the engine, turn off water, release pressure with the trigger, then remove the nozzle. Use the provided cleaning tool to clear the obstruction. Rinse the nozzle with a garden hose for 30 seconds.

What is the pump maintenance procedure?

Drain pump oil after the first 50 hours, then every 100 hours or every 3 months. Use SIMPSON Premium oil or SAE 15W-40. Check the level via the oil sight glass.

How to store the unit for more than two months?

Drain all fuel, change engine oil, remove the spark plug and pour 15 ml of oil into the cylinder, then crank the engine. Drain the water tank and store in a clean, dry place away from sunlight.

What fuels are prohibited?

Do not use gasoline containing more than 10% ethanol (E15, E20, E85). Use only fresh unleaded gasoline (less than 30 days old) with a minimum octane rating of 87.

How to apply detergent?

Insert the black nozzle, connect the external soap injector to the high-pressure outlet, and place the siphon hose into the detergent. Activate the gun after setting the nozzle. Then rinse with clear water.

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.

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.

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.

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 fresh, high-quality #2 diesel fuel for the engine. Fill the tank to a maximum of 1" below the filler neck to allow room for expansion.
