  • Where is the engine made?

    Generac G-Force®  and OHVI engines are designed and manufactured past Generac Ability Systems Inc. at our facilities in Wisconsin.

    The Generac OHV engines are not engineered or manufactured in the U.Southward.

  • How does the Generac K-FORCE® engine compare to air cooled engines used in other brands of generators?

    Unlike other engines used in backup power generation, Generac Thou-FORCE® engines are designed specifically for generators. They are engineered to run for the long periods of fourth dimension required during a severe ability outage or on a job site. They utilize the same blazon of pressurized oil lubrication used to give automobile engines long and trouble-complimentary lives.

  • What type of oil is recommended? How oftentimes should information technology be changed?

    Higher up 32°F, apply SAE 30. Below forty°F and downwardly to -10°F, utilise 10W-30. Synthetic 5W-30 can be used in all temperatures. Oil should be inverse after the first 20-thirty hours of operation and every 100 hours of run fourth dimension thereafter.

Pressure level Washer FAQs

  • What is a pressure washer?

    A pressure level washer is an outdoor power tool that makes cleaning easier by using a loftier-pressure spray of h2o to clean a surface. A gasoline engine or electric motor drives a pump, which is supplied by your dwelling'due south water supply. The water enters the pump at virtually 50 PSI, is compressed (and thus pressurized) inside the pump, and exits the pump at as much equally several thousand PSI, depending upon the unit. This high-force per unit area water travels through a hose to a spray gun. The nozzle at the end of the spray gun directs the high-pressure spray equally you clean.

    The force of the loftier-pressure spray loosens dirt and flushes information technology away. On more professional-grade models, the spray is even powerful enough to strip paint, which is useful in paint preparation. You tin utilize many detergents with a ability washer, too, for even more effective cleaning. And at that place are accessories you lot can purchase that make cleaning fifty-fifty easier.

  • What is "PSI" and "GPM," and why are they of import?

    PSI is short for "pounds per foursquare inch." Information technology is a measure of the water pressure coming out of the pressure washer. A typical garden hose dispenses water at about l PSI, and a coin-operated car wash provides about 700 PSI. A pressure level washer, past contrast, typically dispenses h2o at several thousand PSI, depending upon the model.

    GPM stands for "gallons per minute," and describes how much water is flowing through the pressure washer.

    You'll find both of these ratings on a force per unit area washer, considering they're both important. Together, they provide your pressure washer's cleaning ability. PSI provides the "oomph" you need to lift dirt and grime, and GPM provides the necessary quantity of water to wash it away.

    The existent measure of a pressure washer's cleaning power can be plant by multiplying PSI by GPM. The college the number, the greater the cleaning ability. For example, a garden hose delivering water at 50 PSI and v GPM has a cleaning power of just 250. A pressure washer, withal, delivering water at 2500 PSI and two.iii GPM has a cleaning power of 5750.

  • How practise I select the right pressure washer?

    The start question you should ask yourself is where you intend to use the pressure washer—at dwelling or at work. A pressure washer used primarily at dwelling house probably doesn't need to be equally powerful as 1 that is used on a job site. Around the business firm, for case, you shouldn't demand more than than 3000 PSI. To exist fully productive on the task site, though, you probably need at least 3000 PSI.

    Next, inquire what you desire to make clean. If you're looking to just accept the dirt and grime off the driveway or patio furniture, you tin can use a unit with a relatively low pressure—perhaps 2500 PSI. If, however, y'all program on scrubbing mold and mildew off physical, or prepping a business firm for painting, you should consider a unit with a higher force per unit area.

    Finally, think almost how much cleaning you will be doing. If you lot're cleaning a number of items, or if you need to clean a big surface area, you might want to consider a unit with a higher GPM. More water means more than cleaning power, and a higher GPM volition make the chore go faster.
