Using

Assembly

This Generac pressure washer is easy to assemble. You can click on the link below and watch the assembly process.

You can also follow the steps outlined below and set the machine up at home.

Steps required for assembly:

1. Start by attaching the handle assembly to the handle support. Align the handle and the support, push the latch buttons on the support and start sliding the handle down. The buttons will lock the handle assembly into place.
2. Now, install the hose hook at the back of the handle assembly by sliding it into place.
3. Next, set the colored nozzle fittings onto the handle assembly. You can do this by following the color code laid out on the handle assembly.
4. Connect the siphon tube to the machine and the on-board detergent tank. You can do this in two simple steps:
   1. Attach one end to the machine by pushing it into the opening provided at the top of the high-pressure hose outlet.
   2. Attach the other end into the opening provided on the lid of the detergent tank.
5. Fill the engine oil tank on the left side of the machine with the recommended engine oil. Once done, ensure that the lid is properly secured.
6. Next, open the lid on top of the black color fuel tank. Fill this tank with the recommended fuel. Here are some pointers about this step:
   1. Use clean, fresh, unleaded gasoline.
   2. Minimum rating of 87 octane/87 AKI (91
   3. RON).
   4. Up to 10% ethanol (gasohol) is acceptable.
   5. DO NOT use E85.
   6. DO NOT use a gas oil mix.
7. Now you can connect the high-pressure hose to the water outlet and the trigger gun.
   1. 1. Take one end of the high-pressure hose and attach it to the upper outlet at the back of the machine. Press the hose into the outlet and turn it clockwise until the connection is secure.
      2. Now connect the free end of the high-pressure hose to the opening at the bottom of the gun. You can do this by inserting the hose into this opening and turning it clockwise until the connection is secure.
8. Finally, attach the garden hose to the inlet just below the high-pressure hose outlet at the back of the machine. Press the garden hose into the opening until the connection is secure. Connect the other end to your water supply.

With this final step, your pressure washer is all set up.

Washing

Once the pressure washer is all set up, ensure that all the connections are secure. Once the check is complete, flip the switch at the front of your machine to “on.”

Pull the recoil gently at first. Once there is some resistance, switch to pulling the recoil forcefully.  After the pressure washer is running, squeeze the trigger for about 30 seconds to release all air pressure.

The Generac 7122 SpeedWash comes with multiple nozzle fittings. The table given below can help you decide which fitting can be used by you, depending on the job at hand.

• Turbo (0°) Nozzle: High pressure, swerving throw. Helps remove stubborn grime and dirt 30% faster than regular nozzles.
• Red (0°) Nozzle: Very high pressure, low flow. To clean surfaces like unpainted metal or concrete.
• Green (25°) Nozzle: Medium pressure, medium flow. Ideal for use on sidewalks, lawn furniture, concrete, and brick surfaces.
• White (40°) Nozzle: Lower pressure, high flow. To clean wood, painted brick, and stucco, vinyl, painted siding.
• Black (Soap) Nozzle: Soap nozzle. For applying soap and detergent.
• Soap Blaster (Soap) Nozzle: Soap nozzle with up to 3 times farther reach. Allows you to apply soap and detergent on surfaces that may be out of your reach.
• Power Broom (4 nozzle tips) Nozzle: 12” surface cleaner that works with high-pressure nozzles. Ideal for cleaning flat surfaces like sidewalks and patios.

To use the detergent tank, start by filling the tank with a detergent solution. Ensure that the solution used is suitable for pressure washers. You might have to prepare a diluted mix in case the detergent label asks you to do so.

Now you need to check if the siphon hose is in place. Finally, attach either the soap nozzle or the Soap Blaster nozzle, and you are good to go.

Verdict on the Generac 7122 SpeedWash

The Generac 7122 SpeedWash lives up to the power and superior design elements it promises. With the plethora of attachments that come with it, you can clean any surface quickly and effectively.
