1. Safety Instructions
– Personal Protective Equipment (PPE): Wear safety goggles, gloves, hard hats, ear protection, and steel-toe boots.
– Pre-Operation Check: Inspect the machine for damage, loose bolts, leaks, and worn-out parts.
– Lockout/Tagout (LOTO): Disconnect power before maintenance or repairs.
– No Entry Zone: Keep hands and tools away from moving parts during operation.
– Emergency Stop: Know the location of the emergency stop button.

2. Equipment Components
# Main Parts of a Stone Crusher:
– Feeder Hopper – Receives raw material.
– Jaw/Cone/Impact Crusher – Crushes stones into smaller sizes.
– Vibrating Screen – Separates crushed material by size.
– Conveyor Belts – Transport crushed material.
– Electric Motor/Diesel Engine – Powers the crusher.
– Hydraulic System (if applicable) – Adjusts settings like gap width.

3. Operating Instructions
# Before Starting:
1. Check oil levels (engine/hydraulic system).
2. Ensure belts and chains are properly tensioned.
3. Clear the crushing chamber of any debris or leftover material.
# Starting Procedure:
1. Turn on the power supply (for electric models) or start the engine (for diesel models).
2. Allow the machine to idle for 2–3 minutes to warm up.
3. Gradually feed material into the hopper (avoid overloading).
# During Operation:
– Monitor vibration and noise levels for abnormalities.
– Ensure uniform feeding to prevent jamming.
– Adjust settings (e.g., jaw gap) as needed for desired output size.

# Shutdown Procedure:
1. Stop feeding material first.
2. Let the crusher run empty for 1–2 minutes to clear residual stones.
3. Turn off the power/engine.
