Polish the sides of both primer arms with 600 or up grit sandpaper and
do not apply oil to these, you want them dry, also...keep the primer
channels clean using a Q-Tip, again, apply no oil to the channels. With
doing the polishing tip, it will allow the primer arms to move freely.
Lastly, stick with the Safety Prime...adjust and tweak it until you
get it mastered, it really does work great.
