INTRODUCTION
While in the field, you may come across earlier generations of JET
TECH machines. General operation of these machines is similar if
not identical to our current models. However, certain parts may be
unique to these machines. This information is readily available
from our office. We have endeavoured to make this manual as
accurate as possible. If you find a discrepancy or can't find certain
information, please contact us. We will be glad to help you.
Updates and modifications will be issued as the information
