Pressure Washers

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).
