exchange it, we always recommend that the complete piston/
cylinder assembly by replaced.
a) Hold the piston rod and slowly pull it apart with the
piston head out from the dispensing cylinder (Fig. a).
b) Use a soft cloth to clean the dispensing cylinder and
piston head, or replace them.
c) To replace the piston head, first slide the light grey
safety ring of the piston rod upwards (Fig. c), and then
unscrew the piston head (Fig. c').
d) Screw a new piston head onto the piston rod, and
tighten it securely.
