The more commonplace causes of defective work and their remedies are also listed to prevent, as much as possible, the unnecessary delays which causes a loss in production.

However, due to continual improvements in design, it is possible that descriptions contained herein may very slightly from the machine delivered to you. This merely implies that the machine has been improved to better fulfill your requirements." "Publication No. 6-433-8. Cincinnati Grinders Incorporated, Cincinnati 9, Ohio, U.S.A." [from booklet]
