If these are not your current values, we suggest that you correct them now
and download them using the download procedure discussed in chapter 4.
Before proceeding, observe these warnings:
ATTENTION: As with any machine start-up, install a test
mold. Programming errors, configuration errors, or hydraulic
problems could lead to machine damage or injury to personnel.
ATTENTION: Be sure all machine guards and shields are in
place before proceeding.
