unboxed, and clueless about how much pressure this thing was airmailed to me with.

going to test with a home scale, and was wondering if 40 lbs is about right. i read somewhere about 19 KG compressing the spear about 10-15cm.

any insight appreciated.

Pneumatic guns are usually shipped with around 15 bar in them. See if you can cock it and if it is too easy then add more air with the hand pump, say about 40 strokes, then try again. Repeat until you cannot load it and then let a small amount of air out until you can. Put a bit of oil in the hand pump before you start to lubricate it as in storage the lubricant can dry out.

thanks it felt like over 20 bar tbh, (over 60 lbs on weight scale) but i simply released a bit, and able to comfortably pre load. (scale shows about 38 lbs) will adjust after some time in the water. can you clarify your last sentence though? appreciate the assist, excited to shoot this thing.
The hand pump usually heats up as pressure builds with successive strokes so if you add oil to the end of the pump it lubricates the seal on the pump piston before you start using it. When the pump was assembled at the factory they would have lubricated the seal, but that could be months or a year ago.
Before attaching a hand pump to a gun it is good practice to pull the pump handle back and introduce a couple of drops of oil down the pump bore, then work the pump handle up and down a few times. This action fully lubricates the pump bore and the hand pump can then attached to the inlet valve body on the rear of the gun.
I would like to draw your attention to the Line release lever feature of this gun.
It can lead to an accidental shot when you laid the tench and then pressed on the tench, or simply pressed the tench to the gun with your hand.
