My pressure washer motor is a 3.5 hp Tecumseh 4-cycle motor: model # H35-45696X-B with a DOM: 6074R. The only identifying mark on the pressure washer pump is a circular stamp in the casing showing 7 raised dots out of 12 spaces, with 95 in the middle of the stamp.

Answer
Both Kärcher and Campbell Hausfeld have used Tecumseh engines for their pressure washers. However, the smallest engine I have found for either manufacturer is 4 HP. A manual for Kärcher's pressure washer is at:

A manual for Campbell Hausfeld's pressure washer is at:

The circular stamp may be a date code, perhaps the seventh month (July) of 1995. That would be consistent with your having a 3.5 HP engine, which would be considered too small by today's standards.

No pressure on a pressure washer?

It is a Honda Excell zr3700a, when you press the trigger water comes out but no pressure. Someone mentioned it could be in the trigger, but it sounds more like it is in the pump seals of the hydraulic pump. Any ideas?

And if anyone no of somewhere I could view a manual online I would appreciate it. I have searched, but no results yet.
paulofhouston I have already found that one, it only shows you the part number and description.
