Care & Maintenance Guide
Introduction: Why Proper Care Matters
ProKast neodymium precast concrete magnets and magnetic steel chamfers are engineered to withstand the demanding conditions of Australian precast yards. However, they are precision tools.
To ensure maximum holding force (up to 2200kg), long-term reusability, and to keep your warranty valid, proper daily care and maintenance are essential. Concrete slurry buildup and improper handling are the leading causes of premature failure.
1. Daily / After-Use Cleaning Instructions
The magnetic surface must make direct, flush contact with the steel casting bed to achieve its full holding force. Even a millimeter of dried concrete can drastically reduce the magnet’s grip.
For Precast Concrete Magnets:
- Remove Wet Slurry: Immediately after the pour, wipe away any wet concrete splashes from the magnet casing and button mechanism using a damp cloth or sponge.
- Clean the Base: Once removed from the casting bed, inspect the bottom magnetic face. Use a wire brush or scraper to remove any dried concrete or debris.
- Air Blow: If available, use compressed air to blow out dust and grit from around the push-button mechanism to prevent jamming.
- Oil the Surface: Lightly coat the bottom magnetic face and the steel casing with form release oil or a rust-preventative spray to prevent corrosion.
For Magnetic Steel Chamfers:
- Wipe Down: After stripping the chamfer from the panel, wipe the entire length with a clean rag to remove wet concrete.
- Scrape the Edges: Use a plastic or soft metal scraper to gently remove any hardened concrete from the beveled edges.
- Oil the Magnets: Apply a light coat of form oil to the embedded magnets and the steel body to prevent rust.
2. Best Practices for Use in Precast Yards
- Ensure a Clean Bed: Before placing magnets or chamfers, sweep and scrape the steel casting bed. Debris under the magnet will reduce its hold and can damage the magnetic face when engaged.
- Use the Correct Release Tool: Always use the designated ProKast release lever (crowbar) to disengage the magnet button. Lever it upwards smoothly.
- Position Carefully: Neodymium magnets are extremely powerful. Do not drop them forcefully onto the steel bed; place them gently to avoid cracking the internal magnetic core.
3. What to Avoid (To Prevent Damage)
Critical Warnings
- Never use a hammer: Do not strike the magnet casing or the push-button with a hammer or mallet to engage or release it. This will shatter the internal neodymium magnets and void your warranty.
- Never weld near the magnets: High heat from welding will permanently destroy the magnetic field of neodymium magnets. Keep welding operations away from ProKast tools.
- Do not let concrete cure on the tools: Hardened concrete buildup around the button mechanism will cause it to jam, rendering the magnet useless.
4. Storage Recommendations
When not in use, proper storage extends the life of your ProKast tools:
- Store Indoors: Keep magnets and chamfers in a dry, covered area protected from rain and extreme weather to prevent rust.
- Keep Them Oiled: Ensure all steel surfaces and magnetic faces have a light coating of protective oil before long-term storage.
- Store in the Disengaged Position: Always store the magnets with the button in the UP (disengaged) position.
- Use Protective Spacers: If stacking magnets, place a piece of timber or thick cardboard between them to prevent them from snapping together, which can cause injury or damage.
5. Troubleshooting Common Issues
Issue: The magnet isn’t holding tightly to the bed.
- Check: Is there dried concrete or debris on the bottom of the magnet or on the casting bed?
- Solution: Thoroughly clean both surfaces with a wire brush and scraper.
Issue: The push-button is stuck and won’t press down.
- Check: Is there concrete slurry jammed inside the casing?
- Solution: Use compressed air or a stiff brush to clean around the button. Do not force it with a hammer.
Issue: The chamfer is leaving a rough edge on the concrete.
- Check: Is the chamfer bent, or is there hardened concrete stuck to the beveled face?
- Solution: Clean the chamfer face thoroughly. If the steel is physically dented or bent from misuse, it may need to be replaced.
