Dry, lint-free tissue
•
Light source

Isopropanol
Follow these steps
1. Inspect the piston for signs auf damage.

Hold the rear side of the piston into the light. The refraction of the
light makes dirt particles appear larger.
2.
Recommended:
Even if the piston seems to be clean, perform the fingernail test:
a) Hold the piston and carefully move your fingernail over the
piston surface. The piston is clean when the fingernail test does
not reveal inconsistent or rough areas.
b) Continue with the next step.
3. Carefully rinse the piston, preferably using isopropanol.
4. With a dry, lint-free tissue, rub the piston several times.
5. When no damage is visible and the piston is clean, reinstall the
piston. If the piston is scratched or scored, install a new piston.
