The oil filter on this engine is a paper cartidge type. There will be a black plastic housing with a hex on the bottom of it (just looks like a normal oil filter except black plastic with a big nut stuck to it). Use a suitable sized spanner/socket to loosen off, replace the paper cartridge on the inside and remember to replace the 'o' ring on the housing (top of the thread).
