Do you know what routine service was done? Normaly, by the manual, engine oil and filter, hydro oil and both trans and hydro filters, maybe a fuel filter, and check the air filter along with yes, grease everything would be done at 50 hours. Then engine oil and filter every 100 hours with hydro and trans filters every 200 hours and the hydro fluid at every 400 hours. Again greasing at least every 50 or sooner.
