Pre-Operation Checklist
1. Inspection & Visual Checks
– Check for cracks, wear, or damage on the jaw plates, toggle plate, and cheek plates.
– Inspect the frame and bearings for structural integrity.
– Ensure no loose bolts or fasteners.
2. Lubrication System
– Verify oil levels in bearings and hydraulic systems (if applicable).
– Check for leaks in lubrication lines.
3. Safety Devices
– Ensure emergency stop buttons are functional.
– Confirm guards are in place for moving parts (belts, flywheel).
4. Electrical Systems
– Inspect wiring for damage or exposed cables.

5. Feed & Discharge Areas
– Clear obstructions from the feed hopper and discharge chute.
– Check liner condition to prevent material buildup.

Operational Checklist
6. Start-Up Procedure
– Warm up the crusher with no load before feeding material.
– Monitor unusual noises or vibrations during operation.
7. Material Feeding
– Avoid oversized material exceeding the crusher’s capacity (check feed size limits).
– Ensure uniform feeding to prevent uneven wear on jaws.
8. Performance Monitoring
– Track product size consistency (adjust CSS if needed).
– Monitor amp draw on the motor to avoid overloading.

Shutdown & Maintenance Checklist
9. Post-Operation Steps
– Allow the crusher to run empty before shutdown to clear residual material.
– Lock out/tag out (LOTO) before any maintenance per Bahrain safety standards ([OSHA equivalent](https://www.labour.gov.bh/)).
10. Routine Maintenance
– Grease bearings as per manufacturer’s schedule (high temps in Bahrain may require more frequent lubrication).
– Replace worn jaw liners when thickness is below recommended levels (~60% worn).
11. Environmental Compliance (Bahrain-Specific)
– Control dust emissions with water sprays or enclosures (comply with [Bahrain’s EPA](https://www.moenv.gov.bh
