PROBLEM SOLVING TIPS

Rousselle and Heim presses are rugged and durable. With proper use, care, and maintenance, Rousselle and Heim presses will provide many years of dependable service.

Prompt corrective action when trouble is suspected is not only a good safety habit but will usually result in a minimum of down time and costs for repairs. Small problems could develop into large ones and may also result in a serious accident or damage to the press itself unless corrected immediately.

Although the press may seem to run without any apparent extra effort, continuous overloading does add additional strain to the press components which will result in part failure. Caution must be exercised when selecting the tonnage requirement for a certain job.

We have listed some general guidelines that when followed can save the press from damage and possible injury to the operator.

1. Do not overload your power press.
2. Do not use material which exceeds the capacity rating of the press.
3. Equally distribute the load over the length of the bed area. Never run an off centered load.
4. Lubricate as specified. Do not overgrease the clutch.
5. Be alert for unusual symptoms and take corrective action promptly.
6. Replace worn or damaged parts immediately.

For the convenience of the user, we have separated the trouble shooting tips into sections. These tips are offered as an aid. They are not intended to be complete nor is the order in which they appear relative to their importance. We have shown some typical “problems” and their “probable causes.” If the desired information is not on this list, do not hesitate to call the factory for assistance.
