You should never reset the piston rod until it is time to
remove the used PenFill 3 mL cartridge and insert a new one.
If the reset mechanism locks, it is usually due to improper
technique. Gently turn the mechanism side to side until it
unlocks. Then call our toll free number (1-800-727-6500) so
that we may go over your technique with you.
SECTION 1 (cont.)
The end of the piston rod should
be flat against the end of the
reset mechanism prior to
inserting each new PenFill 3 mL
cartridge. It should not be
sticking out.
If the piston rod is
sticking out:
Turn the end of the reset
mechanism in a clockwise
direction until it is no longer
sticking out. Never push the
piston rod back in.
