Sir, the reason why the shafting of the hoist pump is broken, because the main relief valve of the hoist is adjustment is high, you should start with a low adjustment, then raise slowly the pressure, until is placed in the correct adjustment.Before start the engine,the main relief valve of hoist, must be adjust low, so that the shafting of the pump is not broken.But the same time, use a pressure gauge.
