The 20/50 oil is not in the engine, it is what is used in the hydraulics.
He was trying to start the engine with the hydraulics running creating a huge load on the engine. Once they were turned off, the machine starts like normal.
In the summer heat you can start the unit even under load, but when cold you have to turn them off. You should always turn them off when starting.
