A few things that should be asked.
Was the bottle full?
Was the marker cocked before you started?
Was the bottle valve on all the way (on/off valve)?
Was the bottle screwed on all the way (pin vavle)?
Was the bolt clean and lubricated?
If the answer is yes to all the above, then im stumped.
I recomend stripping the marker, cleaning it thourghly, lubricating the bolt and hammer, then reassembling it.
Then try again with a full bottle.
