Huben Huben GK1 Loading Question

[Ezana4CE]

Can anyone please explain why it is recommended to fill the GK1 reservoir before loading the magazine? I got this information from the GK1 User’s Manual.

I ask because the magazine release lever and magazine are under less tension at lower reservoir pressures. This makes loading the GK1 easier to me. Are there valid reasons not to re-load before topping off the GK1?

Is this simply a safety precaution?

Less chance of shooting your eye out Kid... which with a GK1 could easily be fatal.

Well I don’t want to shoot myself in the foot, especially at full pressure This is more probable when loading with a topped of reservoir. Also when loading after topping off the magazine release lever is under more tension and more likely to slam harder against the receiver - something the User’s Manual advises us not to do.

However, if there is a chance that something occurring during the filling process causes the GK1 to discharge a projectile (or projectiles) then whatever is on the other end of the muzzle gets it. I try to maintain the habit of keeping the muzzle pointed at the ground while filling and watching the manometer. These are my thoughts, but I’d like to know the logic behind whats recommended in the User’s Manual.

I believe the advice belongs to an empty air tank, which makes some sense as the shut off valve is biased by tank pressure. In other words there needs to be some air tank pressure. You are also correct that there is less detent pressure on the magazine lever when the tank is at less than max pressure. In that light, I always load my GK1s after I have shot a magazine. Then I recharge the tank to 300 bar. After one 17 shot magazine the air tank is about 200 bar+..

i've had my k1, after a jam and drain, discharge the action while filling it back up. its rare and avoidable, but possible, so i can understand the disclaimer.

@wimpanzee Did you post about this in an existing thread? If so, can you link that thread?

no, it was years ago when i first got my old k1, like 2018...was figuring out how to not jam it with crappy pellets....

@wimpanzee Ok. So that I understand you correctly, after clearing the jam and refilling your Huben, it began to discharge pellets?
