Understand the Manufacturer’s Recommendations

7004513
Start by reviewing the manufacturer’s guidelines and maintenance recommendations. Sauer Danfoss typically provides specific intervals for routine maintenance tasks, including inspection, oil changes, filter replacements, and any necessary adjustments. Refer to the service manual to create a foundational schedule that adheres to these guidelines.
Perform a Risk Assessment
Conduct a risk assessment to identify the operating conditions and potential issues that may impact the pumps’ performance. Consider factors such as operating hours, load conditions, and environmental factors (like temperature and moisture). This assessment will help determine how often you should perform maintenance tasks beyond the basic manufacturer recommendations.
Create a Maintenance Checklist
Develop a maintenance checklist that outlines all the necessary tasks to be performed at each maintenance interval. Common tasks include:
Checking fluid levels and quality
Inspecting for leaks and wear
Lubricating bearings and other moving parts
Testing performance and efficiency
Replacing filters and seals
Checking electrical and electronic components
Establish Routine and Predictive Maintenance Intervals
Divide your maintenance schedule into routine and predictive maintenance intervals. Routine maintenance could occur monthly, quarterly, or semi-annually, depending on usage. Predictive maintenance, which may involve advanced diagnostics, can be scheduled annually or bi-annually to assess the pump’s condition and predict potential failures before they occur.
