PREVENTIVE MAINTENANCE
Maintenance checklist
Each use
- Wash off all concrete before it hardens
- Check for dents or deformation
Monthly
- Remove rust and lightly oil to prevent corrosion (wipe clean before use)
- Check the tamping rod is straight and its end rounded
Six-monthly / annual
- Dimension check of top and base diameters, height and wall thickness
- Replace cones that are out of tolerance or badly dented
SAFETY
Safety precautions
Before you work on the Slump cone
- Fresh concrete is alkaline and can burn skin: wear gloves, boots and eye protection.
- Lift with your legs; a filled sample bucket is heavy.
- Wash any concrete off skin immediately with clean water.
