Quality Tools for Smart Cleaning
2. Changing the seals
When the proportioning pump starts to "stutter", or
doesn't operate at all in low flow rates, it is time to
change the piston seals.
When the proportioning pump stops sucking sup-
plements, or starts doing so irregularly, it is time to
change the suction seal.
1. Release and take off the cover (9) by anticlock-
wise turning it with your hands.
2. Pull out the piston body (2) and take it out of the
body (31), pulling it carefully upwards.
3. Use a pair of pliers to grasp the rim of the upper
piston seal (41), pull firmly and remove the seal
from the piston body.
4. Use a pair of pliers to grasp the rim of the lower
piston seal (42), pull firmly and remove the seal
from the piston body.
Beware: not to damage the piston body with the
pliers.
