A detailed Hydraulic Press WEEKLY preventive maintenance Inspection checklists
1. Safety Precautions
2. Visual Inspection
3. Fluid Levels
- Locate the reservoir and open the cap.
- Use a dipstick or sight gauge to assess fluid level.
- Add hydraulic fluid slowly until the recommended level is reached.
- Avoid overfilling; wipe away any spills.
- Draw a sample of fluid into a clear container.
- Observe fluid color; it should be clear and consistent.
- Check for cloudiness or discoloration indicating contamination.
- Dispose of sample responsibly after inspection.
- Locate the fluid filter and inspect its exterior.
- Remove the filter and check for dirt or debris.
- Replace with a new filter if it appears clogged.
- Ensure proper sealing upon reinstallation.
- Locate the reservoir and check the fluid level against the marked indicators.
- If the level is below the recommended mark, add the appropriate hydraulic fluid.
- Use a funnel to prevent spills and ensure clean handling.
- Observe the fluid's color; it should be clear and free of particles.
- Check for discoloration or cloudiness, which may indicate contamination.
- If the fluid appears degraded, plan for a replacement.
- Locate the fluid filter and visually inspect it for dirt or blockages.
- If the filter appears dirty, replace it with a new one following manufacturer guidelines.
- Dispose of the old filter following environmental regulations.
