Before I inject.

[Blackfoot]

I have one question. Do you have to draw an amount of air equal to the amount to be injected and then push the air into the bottle? If so, why? Thanks.

yea it helps with the withdraw of gear

[Blackfoot]

Thanks man. You inject the air into the bottle, not the oil, right?

yea if u gonna say use 1 cc then pull back on the syringe and inject 1 cc of air in the vial then withdraw the gear...

I find it works better if you inject a bit more air than you draw, Makes it easier when you're using a small needle.

yes a little more air is better... the pin almost fills itself for a little bit until you have to pull the plunger back to fill it the rest of the way because of the air pressure...
