Inspect Fuel System
Check:
- Fuel lines
- Fuel tank
- Fuel cap
- Fuel filter
Look for leaks or contamination.
Examine Blades
Inspect blades for:
- Ρωγμές
- Υπερβολική φθορά
- Bent edges
- Loose mounting bolts
Damaged blades can affect floor quality and machine balance.
Inspect Fasteners
Construction equipment experiences constant vibration.
Check:
- Nuts
- Bolts
- Washers
- Blade mounting hardware
Loose hardware should be tightened immediately.
Verify Safety Features
Before operating the power float trowel, confirm that:
