After power‑on, jog the start button and check whether the motor rotates in the correct direction. If the direction is wrong, adjust the phase sequence (for three‑phase supply) or rewire according to the manual.

Q8:What is the daily operating procedure for ACL‑623Y?

A8:

Startup:

1. Turn the power switch to “ON”; the power indicator lights up.

2. After confirming correct voltage, press the Start button; the machine starts running.

3. Place the shoe material into the grinding area and perform edge roughening or fine grinding.

Shutdown:

• After finishing, simply turn the power switch to “OFF”.

Q9: What safety precautions should be taken during ACL‑623Y operation?

A9:

1. Do not wear loose clothing with pendants or draperies (e.g., ties, scarves) during operation; cuffs should not be oversized. Long hair must be tied behind the head.

2. Children and unauthorized persons must not approach the machine.

3. The operation manual must be kept readily available to the operator at all times.

4. Warning labels on the machine (e.g., “Risk of electric shock”, “Danger of injury”) must be kept clean and visible.

5. The safety panels are sealed with screws and can only be opened by authorized maintenance personnel after power disconnection.

6. Do not put hands or foreign objects into the grinding area while the machine is running.

IV. Structure et composants de la machine

Q10:What are the main components of ACL‑623Y?

A10:The machine mainly consists of:

• Frame and workbench: Support the whole machine and provide an operating platform.

• Grinding head (wheel): Performs rough and fine grinding.

• Drive motor: 0.75kW motor driving the grinding head.

• Dust collection system: Built‑in dust collector (or external dust bag) for collecting grinding dust.

• Electrical control system: Power switch, start/stop buttons, indicator lights, etc.

• Safety guard: Covers the grinding area to prevent flying debris.

Q11: How does the dust collection system of ACL‑623Y work?

A11:The machine is equipped with a powerful dust collection system. A suction port is located near the grinding head, and an internal fan or external vacuum source draws the dust and dandruff into a dust collection bag (or box), keeping the working area clean and reducing health hazards from dust.

五.Maintenance & Servicing

Q12: What are the daily maintenance items for ACL‑623Y?

A12:

1. Regular cleaning: Stains will accumulate over time; clean the machine surface and grinding area with a dry cloth or compressed air periodically.

2. Empty dust bag: Regularly clean the dust‑collecting bag to prevent clogging and maintain suction efficiency.

3. Check electrical connections: Regularly inspect load input/output terminals for looseness to avoid arcing and equipment damage.

4. Monitor noise level: If noise increases significantly, inspect bearings, belts and other wearing parts, and replace if necessary.

Q13: What is the noise standard and inspection interval for ACL‑623Y?

A13:At the operator position, normal operating noise is approx. 78 dB(A) with a peak not exceeding 130 dB(C). Since prolonged use may increase noise, it is recommended to check the noise level every two years to ensure compliance with safety standards.
