PG9602™ OPERATION AND MAINTENANCE MANUAL
5.3.1.1
The 10 kPa/kg piston insertion tool is used to
facilitate the insertion and removal of the piston
to / from the cylinder. Because of the large
diameter of the piston and the very small gap
between the piston and the cylinder, there is a
risk of getting the piston stuck (cocked) in the
cylinder if the two parts are not properly
aligned. The tool aligns the piston with the
cylinder.
Cleaning the cylinder alignment ring
When the tool is used, the white plastic cylinder
alignment ring comes into contact with the
polished (critical) surface of the cylinder. The
alignment ring is delivered clean and must be kept clean to avoid transferring
contamination to the cylinder.
transfer contaminants to the cylinder, it must be cleaned. To clean the white
plastic alignment ring either cleaning method used to clean the piston-cylinders
can be used.
The red-colored surfaces do not come in contact with any critical surfaces of the
piston-cylinder and therefore can be handled without concern of inducing
contamination.

Caution
Do
not
touch
the
alignment ring of the piston insertion
tool. The ring will come in contact with
the inside of the cylinder and could
.
cause contamination
Clean the white alignment ring using either the water/soap method or the
glass cleaner method.
Use a slow steam of dry gas to blow off any unseen lint or dust.
After using the tool, rewrap it in plastic wrap to keep it clean and store in its
plastic container.
