Troubleshooting (Formed Staples)
The quality and quantity of work that can be produced with the Number 7 Stitcher is dependent upon
the operator making all adjustments as accurately as possible, and carefully maintaining the machine.
The cause of staple imperfections usually can be traced to inaccurate settings and adjustments or
normal wear of moving parts. In the event of trouble of this nature occurring, the operator can refer
to the following Trouble Shooting Chart and quickly locate and remedy the causes of the trouble
thereby reducing the time the Stitcher is inoperative.
The first column of the chart illustrates the imperfect stitch while the second column describes the
imperfections or troubles. The third column lists the probable cause or causes for the given trouble,
while the fourth column lists the remedy or remedies for the troubles and also refers to the paragraph
in this book in which will be found detailed information for making the necessary adjustments. If
stitching is defective, the operator can compare the staple produced with the stitches illustrated in the
chart and by carefully reading the information given for each type of imperfect stitch, remedy the
cause of the imperfection.
