Which is pump oil hole for Sears power washer ?


Hi all, I have a Sears 2550 psi "Quick Start" power washer, model 580-752550 and managed to "misplace" the manual and don't have time to get a new one today (Sears doesn't archive them). There are two "oil fill" holes, one for pump, one for engine and they look the same on opposite sides of the engine. Can somebody tell me how to determine which is for pump oil and which is for engine oil,

Oops, screwed up last append before finishing. I need to know which is engine oil hole and which is pump oil hole on my Sears 2550 psi "Quick Start" pressure washer and how much of each to add (or do you just fill it to the top of the hole ?) And is there a drain plug for each or do you tip and dump it out the fill hole ?
(Needless to say, lost manual and Sears doesn't archive manuals).
Thanks, Bob

If the oil fill holes are both on the engine casting they are for the engine not the pump. The one for the pump should be forward of the engine shaft and on the pump casting.

Thanks. I just thought it odd that there were two oil fill holes and caps (both appear to have fresh engine oil to the top) on opposite sides of the engine casing. Fired it upAnd, BTW, I could find nothing that looks like an oil fill port on the pump itself for pump oil (though Sears sold me pump oil). Is it possible the pump is permanently oiled or if not what does the pump oil fill hole look like on the pump ? Thanks for responding. Bob
