Why does the pressure in my Hytorc Stealth 2 system not increase?

The pressure in the system might not increase due to several reasons. There could be oil leakage because of a defective piston, piston seal, or O-ring, in which case you should replace the defective part. Alternatively, there might be leakage in the pressure relief valve or the two oil line connections; try tightening the leaking connection using a 9/16” open-end wrench. A worn motor coupling, indicated by the pump making sounds like pebbles in a tin can, can also cause this issue, requiring replacement of the motor coupling. Another cause might be the air shut-off valve failing due to excessive moisture or dirt in the air supply, which can be resolved by cleaning the air shut-off valve and the air lines. Lastly, the valve in the remote control might have failed and needs replacement.
