What should an operator do in tight working conditions to ensure precision?

Lowering the engine RPMs in tight working conditions is advantageous because it allows for better control and precision. When the engine runs at a lower RPM, the hydraulic systems operate more smoothly and predictably, which is crucial for tasks that require accuracy, such as digging, grading, or maneuvering in confined spaces. This lower speed reduces the machine's responsiveness, making it easier to make fine adjustments without risking sudden movements that could lead to accidents or damage to the site.

In contrast, increasing RPMs can lead to faster and less precise actions, which may be problematic in tight areas where careful positioning is essential. Shutting down the machine would halt all operations and would not help achieve the precision needed. Ignoring RPM considerations altogether disregards an important aspect of machine control, which can compromise safety and the quality of work performed. Thus, operating at lower engine RPMs is the best practice for ensuring precision in tight working conditions.
