Wow thank you! This is incredibly helpful! My spanish is rusty but he says something in the beginning about hi/lo power, “if load spear at low power never switch to hi” i think is what he said, what is the reasoning behind this? His custom tools are pretty sweet, i need To make one of those cutaway screw drivers and t handle tail cap removers.

On these Salvimar guns the use of the low power setting for loading means you utilize the easy loading or progressive loading feature of the gun. Once the gun is cocked the selector lever can be set to either high power or low power. If you carry out a low power shot and leave the selector setting at low power then you don’t release the air in the main tank that was compressed during loading and then only have to recompress what was used for the actual shot for the next reload. On the other hand if you flip the selector lever to high power after a low power shot that pressurized air is lost and the gun is back to even pressure throughout its inner chambers. Unfortunately due to the reversed gate positions and a different upstream valve used in the Salvimar guns a lower pressure in the inner barrel to that in the main tank makes it virtually impossible to budge the selector lever from low to high as the higher pressure in the main tank will hold the valve shut because it is operating an upstream valve. Most other pneumatic speargun brands use downstream valves and they don’t have this problem. If the power selector will not budge then the cure is to add more air to the gun with the hand pump and once the pressure equalizes throughout the upstream valve will open with a slight push on the selector. If you just reload the gun after the low power shot this has the same effect.
