How to safely remove pump off presta valve? No matter what I try I can't seem to remove the pump off my threaded presta valve without injuring my hands on my wheel spokes.

I'm beginning to think I'm doing something wrong.

After unlocking, I just pull until the pump valve comes off.  Sometimes it is a fairly simple process.  Other times I have to use quite a bit of strength.  And the worse times I come in contact with the spokes and lose some skin.

Any tips would be appreciated. I own an Avenir Air Source Pro pump with a dual head pump valve.
I used to skin my knuckles every time I took the chuck off the valve.  Then I figured it out (pain is a learning curve accelerator).

Position the wheel so the presta valve is closest to you and pointed away from you.  Use your thumbs on either side of the wheel to push the chuck straight off (toward the hub of the wheel).

This prevents the presta stem from being bent/broken and limits how far you hands can move when the chuck pops off.  No more bashed knuckles.
