2.3 Dismantling the dosing units
700 Dosino, Instructions for Use

Use the piston pliers (6.1546.030) to pull the
dosing piston out of the cylinder:
• Press the white knob of the piston pliers.
Two wire loops appear at the piston pliers tip.
• Position the piston pliers so that these wire
loops surround the piston peg.
If you now release the knob carefully the piston
pliers will snap shut and you can pull out the piston
with the white knob (some force is required).
• The glass cylinder can now be
removed from the cylinder
base by twisting it firmly.
Leave the black stopcock washer
in the cylinder base.
You can now clean or replace the individual components, such as
the cylinder or the piston.
See chapter 3.3 for cleaning instructions.
Please note! It makes no sense to replace the cylinder or the pis-
ton separately. Always replace both, if necessary.
