Servicing of Tata 709

The model of my truck is Tata 709 which is a four stroke diesel engine,I serviced it at 49708km using the following servicing routine which you can follow.
Firstly,I changed the engine oil by loosing the sump bolt using a 24mm combination spanner,then drained the old oil into an oil pan and tight sump bolt properly to avoid leakage,I loosed the old oil filter and two gas filters and replaced them with new ones then filled the engine with engine oil of 10.5litres(15w40),then finally greased the nipples
Inconclusion,my next service would be at plus 5000km to the present km, which will be at 54708km.
