Floor Grinder Maintenance Schedule Workflow

Steps

1. 1

   Daily (Before Each Use)

   Visual inspection: check power cord, shroud condition, segment tightness, dust port connection. Listen for unusual sounds during startup. Check oil level if applicable.

   Daily checklist:\n- [ ] Power cord intact, no cuts\n- [ ] Segments tight, no cracks\n- [ ] Shroud seal intact\n- [ ] Dust port clear\n- [ ] No unusual vibration on startup\n- [ ] Emergency stop functional

2. 2

   Daily (After Each Use)

   Clean machine thoroughly. Remove all concrete dust from motor housing, vents, and moving parts. Compressed air for hard-to-reach areas. Store segments properly.

   Pro tip: Concrete dust is abrasive and hygroscopic. Left on the machine, it attracts moisture and grinds bearings.

3. 3

   Weekly

   Check belt tension (if belt-driven). Inspect planetary gears for wear. Lubricate pivot points. Check wheel bearings for play. Inspect electrical connections.

   Weekly checklist:\n- [ ] Belt tension and condition\n- [ ] Gear teeth inspection\n- [ ] Bearing play check (grab plate, wiggle)\n- [ ] Lubrication points\n- [ ] Electrical connection tightness

4. 4

   Monthly

   Deep clean motor housing. Check carbon brushes (if applicable). Inspect all bolts and fasteners for looseness. Test GFCI protection. Calibrate speed controller.

5. 5

   Quarterly

   Replace air filters. Check and replace worn belts. Inspect planetary gear oil (change if dark/metallic). Professional bearing assessment if high hours.

6. 6

   Log and Schedule

   Record all maintenance in log book with date, hours, and findings. Schedule next maintenance. Track consumable replacement intervals.
