20 Most Recent Northstar Pressure Washer 2800 PSI Questions & Answers

There should be a drain plug (bolt) at the bottom of the pump to drain the oil. Undo bolt and drain the oil. Replace bolt and fill pump with new oil. Look for a sightglass on the side of the pump. Fill so the oil level is in the centre of sightglass.

There isn't an adjustment for pulling the cleaning solution out faster or slower. It's an automatic function, based on the size of the power washer (meaning it ****s at different rates for different sized washers). Here's a link to the manual for more information:
Hope this helps!

Gasoline goes bad after sitting for an extended period of time.
Old school people would drain the gas out of the tank but found this lead to rust forming in the tank.
Now it is best to fill the tank with high octane gas and use a winterizing fuel additive to prevent problems.
Also remove any water from the hoses.
In the spring replace the gas and change the oil and you should be good, changing the spark plug would also be beneficial.

The oil in the pump is probably leaking because a seal is blown and water is getting into the piston housing. Take a look inside at the oil. It should be brown and translucent. If it is gray, white or milky, you have a blown oil seal. This reservoir should only be 1/3 full of non-detergent oil to begin with. Hope this helps

I think you mean an UN Loader this is a valve that redirects (bypasses) the pressureized water back into the intake when you release the trigger When it is not working the machine continues to build pressure and will bog down

If it really bogs down to where the engine is struggling....it's the carburetor. It's not allowing the engine the fuel/air ratio it needs for peak performance.

If it is a twist coupler which won't turn, i use a pipe wrench or channel locks. If it's a quick coupler socket and the sleeve won't pull back, the quick coupler plug is bad. If you can't get them apart, both should be replacedTodd Lehkereplaced.
