1st start let it run for bout...say 20 mins,
i wouldnt let it rev up&down,
shut it down&check the plug for soot&such, look for any sign of stuff leaking...can never be too scrutinous.
check all the nuts&bolts see if they loosened up
after 5 hrs of running, change the oil

sounds good to me,is it true they will use a little oil til carbon seals them up?

FWIW, the few pressure washers I've seen the water needs to be hooked up and turned on to run the engine otherwise it burns up the water pump. Read your owners manual to see if that is the case with yours. Sorry if I'm being captain obvious here

didnt you say you were using that pressure washer motor for a different app?

at first 5 hours, change the oil. At 10, change it again. Then at the 20-25 hour change it once more and you should be good. At the 20-25 hour mark, you could put a quality synthetic oil in it. I broke in my 4 hp generator similar, at 20 hours, it got its' 4th change of oil. at that point, the oil was really clean with no visible metal glitter/shavings in it. Of course you want to slowly increase the load on it too. put a full load on it at 3-5 hours.

At first you run it with no load for 20-30 minutes. then slowly increase the load or pressure every hour On you engine driven pressure washer if that's what its on.

I dont know if you want to trust yourself cutting it.... :fing20:

ok im not going to cut it but what can i use to raise the motor so the blade is in the deck like it origonally was? im only putting the motor on to break it in and to get the origional motor off so it can be overhauled,then ill put the origional motor on and look for somthing else the motor can be on.
