Hello,

This sounds like your main relief is weak. You can try adjusting it by turning the set screw in. You should do this with a pressure gauge to prevent damage to the pump.

Since this is a problem is with both lift and tilt circuits, it must be the main relief.

Attached below are specific instructions on testing and adjusting the relief valve.

Please let me know if you need further help.

Thanks,
