Pre‑start‑up Inspection & Preparation

Complete comprehensive daily inspection before power‑on every working day. Unqualified conditions must be solved before starting production.

1. Check power supply condition: Confirm that on‑site voltage and frequency match the machine rated parameters. Voltage deviation shall not exceed ±10% of rated value, otherwise it may burn out motors and PLC control modules.
2. Check hydraulic oil tank: Observe hydraulic oil level through oil level sight glass. The oil liquid must stay between minimum scale mark and maximum scale mark. The recommended hydraulic oil is 46# anti‑wear hydraulic oil. If oil is insufficient, add qualified hydraulic oil of the same brand and model. Do not mix different types of hydraulic oil.
3. Inspect hydraulic pipeline system: Check all hydraulic pipes, joints, flanges and cylinder connections for oil leakage, crack and loose fittings. Tighten loose connectors; replace aging or damaged hydraulic hoses in time.
4. Test safety protection components: Press emergency‑stop button and reset it; test safety light‑curtain blocking response; check all safety interlock switches can trigger machine stop normally. If any safety device fails, do not start the machine.
5. Inspect feeding conveyor system: Check conveyor belt condition, make sure no crack, damage or serious deviation. Clear stones, metal fragments and sundries stuck between rollers and belt. Adjust belt tension if deviation appears.
6. Fastener inspection: Check main frame bolts, cylinder fixing bolts, liner‑plate fastening screws, make sure no loose status. Tighten loose fasteners.
7. Check automatic wire‑tying unit: Install steel wire with specified diameter, ensure wire feeding path is smooth without blockage. Prepare enough qualified baling steel wire for continuous production.
8. Confirm ground foundation condition: The machine shall be installed on reinforced concrete foundation as per foundation drawing. Check anchor bolts are fastened tightly, no obvious vibration when machine runs.
