I fitted new hoses to the lobe pump and now the engine stalls as soon as I start the power pack, what am I doing wong?
A. The Hydraulic flow is controlled by pressure feed back, so until the new hoses are full of oil, the pump will try to instantly go to full flow. Close the flow control to the new hoses and start the engine, then slowly open the flow control until the hoses are full of oil. Do not forget to top up the oil level afterwards.
