One the AMH automated mass handler and mass set have been removed from the PG7601
Platform, proceed as follows to remove the piston-cylinder module:
Unscrew the piston-cylinder module from the PG7601 Platform mounting post.
Hold the module by the knurled circumference and rotate it counter-clockwise all the way
out until it can be removed from the mounting post.
Figure 52.
PG7601 piston-cylinder module installation
Install in bullet case.
If the piston-cyllinder module is to be stored or shipped, install it in
the dark grey, PVC, bullet case in which it was delivered. Thread the module into the
bae of the case, then install the case cover.

INSTALLING THE PISTON-CYLINDER MODULE
To install the piston-cylinder module into the PG7601 Platform mounting post, the AMH
automated mass handler and mass set must NOT be installed.
To install the piston-cylinder module into the PG7601 Platform, proceed as follows:
Remove the PG7601 Platform mounting post plug.
If it is present, unscrew the
ORANGE plastic mounting post plug that is installed in the PG7601 Platform mounting
post. Rotate counterclockwise to remove.
Remove the piston-cylinder module from its bullet case.
Open the piston-cylinder
module bullet case by rotating its lid counterclockwise. Remove the piston-cylinder
module from the bullet case base by unthreading it from the case. Hold the piston-cylinder
module body by the knurled area and rotate it counterclockwise.
Place the piston-cylinder module in the PG7601 Platform mounting post.
Lubricate the
module threads very lightly with the Krytox grease supplied with the PG7601 accessories. Place
the piston-cylinder module (thread down) into the PG7601 Platform mounting post (see Figure 52).
Screw the piston-cylinder module into the PG7601 Platform mounting post.
Rotate
the piston-cylinder module clockwise until all threads are engaged and there is NO gap
between the piston-cylinder module and the PG7601 mounting post. Slight resistance
will be encountered in the second half of travel as the piston-cylinder module O-rings
seat in the mounting post.
Low torque rotation by hand is all that should be required to fully seat the piston-cylinder
module into the PG7601 mounting post. Never force the piston-cylinder module into the
mounting post.
