I have found you add about 4-5 oz of pump oil, the black plug between the hose outlet and hose inlet is the pump oil. As for the engine oil when I changed it I measure how much comes out then I put that much new oil back in it shouldn't be more than 5-6 oz. hope this helps...............................
The detergent injector ratio for a Sears pressure washer varies, according to the type of brand. The ratio of some pressure washers is 12 to 1 while others are 7 to 1.
There are Sears service/repair centers across the country. Most have the schematics/diagrams you need and carry the parts.

When buying a power washer, one must decide on the PSI and whether to buy an electric or gas powered washer. Pressure Washer Direct offers a wide selection of pressure washers to choose from. Other retailers include Costco, Sears, Home Depot, Lowes, Rona and Canadian Tire.
You need to put the black (45deg) tip on the wand. It will then allow the pressure to drop enough for the soap to be drwn into the hose.

The manual says to buy a bottle from an authorized dealer and shows no amount, however Sears has the replacement parts and a on-line manual which sells the aforementioned oil. It is a full synthetic oil in a bottle which Sears lists as 5.3 oz. That is what I will put in my 01903 pressure washer. Hope this helps.
