Use this form for pre-start checks and abnormality records. Print it and keep it near the equipment, or include it in the team's inspection files. Link inspection results and abnormalities to the corresponding follow-up actions.
⚠ Safety notice:Before inspection, confirm that the workpiece is securely placed or unloaded. If you find unusual noise, loose structures, cracks, brake failure, tooling that will not release, or equipment rising or descending without a command, stop using the equipment immediately and contact the site supervisor or manufacturer. Unqualified personnel must not dismantle or modify pneumatic circuits, load-bearing structures or safety devices.

02Pre-shift inspection items
Check each item before the first operation of every shift and record the results on the printed form.
| No. | Inspection point | Inspection details | Acceptance criteria | Result | Abnormalities / Corrective actions |
|---|---|---|---|---|---|
| 01 | On-site environment | Check whether there are people, obstacles, oil on the ground or debris within the working radius. | The working area is clean, the passages are clear, and there is no obvious interference. | □Passed □Abnormal □N/A | |
| 02 | Equipment appearance | Inspect the column, main arm, secondary arm, brackets and covers for deformation, impact damage or abnormal wear. | No obvious deformation, cracks, impact marks or abnormal wear. | □Passed □Abnormal □N/A | |
| 03 | Base / Anchor fixings | Check the base fit, anchor bolts, embedded parts or mobile base locking status. | The base is stable; the bolts are not loose; the mobile base is locked reliably. | □Passed □Abnormal □N/A | |
| 04 | Load-Bearing Connections | Check the main load-bearing bolts, pins, circlips, cotter pins and connecting flanges. | All connections are complete, with no looseness, missing parts or obvious wear. | □Passed □Abnormal □N/A | |
| 05 | Rotary joints | Push the manipulator gently and check the rotation status of the main joint, middle joint, and front joint. | Smooth rotation without binding, unusual noise, excessive movement or clearance. | □Passed □Abnormal □N/A | |
| 06 | Joint brakes | Check that each joint brake and its button or knob function correctly. | The braking response is normal and there is no obvious drift after locking. | □Passed □Abnormal □N/A | |
| 07 | Lifting balance | Test lifting and lowering without a load, observing any uncommanded upward or downward movement or vibration. | Stable unloaded balance and smooth lifting/lowering, with no abnormal sinking. | □Passed □Abnormal □N/A | |
| 08 | Air-Supply Pressure | Check the air-preparation assembly and pressure gauge for supply pressure and fluctuations. | The pressure is stable and usually not lower than the equipment requirements; there are no abnormal fluctuations. | □Passed □Abnormal □N/A | |
| 09 | Filter-regulator | Check the filter cup for water accumulation, oil stains, cracks and drainage status. | There is no excess water accumulation in the filter cup; there is no damage; drainage is completed when necessary. | □Passed □Abnormal □N/A | |
| 10 | Air Tubing and Fittings | Inspect air hoses in moving areas for kinks, wear, bulging, leakage or disconnection. | Hoses are intact, fittings are secure and no hose is pulled taut during movement. | □Passed □Abnormal □N/A | |
| 11 | Control Handle | Check buttons, handles, knobs, markings and hose/tube retention. | Buttons return normally, labels are clear and the operating handles are secure. | □Passed □Abnormal □N/A | |
| 12 | Tooling connection | Inspect the tooling connection flange, quick-change mechanism, lifting points, locating pins and fasteners. | Tooling connections are secure, lifting points have no cracks and quick-change locking is reliable. | □Passed □Abnormal □N/A | |
| 13 | Clamping / Vacuum / Release | Test gripping and release without a load. For vacuum tooling, inspect the suction cups, vacuum gauge and filter. | Gripping and release complete correctly; cups are undamaged; vacuum builds and releases normally. | □Passed □Abnormal □N/A | |
| 14 | Travel limits / Protection / Trial operation | Inspect travel limits, collision stops and retention structures, then complete an unloaded or low-load trial run. | The limit is effective; there is no interference in the path; the action is stable and the operating position is safe. | □Passed □Abnormal □N/A |
03Weekly and monthly inspection items
The maintenance team or equipment supervisor should organize periodic inspections.
| Interval | Inspection items | Inspection Details | Recommended Action |
|---|---|---|---|
| Weekly | Load-bearing bolts and welded areas | Inspect the main supports, arms, base and tooling connections for looseness, cracks or weld separation. | If looseness is found, stop the equipment immediately and tighten the connection. If cracks or weld separation are found, stop using the equipment and contact the manufacturer. |
| Weekly | Rotary joints and bearings/bushings | Check whether the rotation is smooth and whether there is any abnormal noise, enlarged gap or eccentric wear. | Record abnormal locations; arrange maintenance, adjustment or replacement of worn parts if necessary. |
| Weekly | Air hoses, cable carriers and moving cable bundles | Check for tension, rubbing or kinking along the motion path, and for loose retaining clips. | Secure the lines again with sufficient movement allowance. Replace damaged hoses or protective sleeves. |
| Weekly | Tooling wear parts | Check whether the jaw pads, suction cups, hooks, positioning blocks, and anti-scratch pads are worn or aged. | Replace the component when wear compromises gripping safety; never operate it in a degraded condition. |
| Monthly | Brakes and travel limits | Check joint brakes, mechanical travel limits, collision stops, retaining pins and safety-function operation. | Adjust or replace failed parts and confirm that locking and limiting are reliable. |
| Monthly | Overall balance and working envelope | Check unloaded/loaded balance, working radius, lifting stroke and path interference. | Reassess the design and tooling after workpiece or workstation changes. |
| Monthly | Nameplates and warning signs | Check whether the rated load, operating instructions, and safety warnings are clear and complete. | Replace missing or illegible labels to prevent operating errors. |
04Abnormality handling and sign-off
Record any abnormality found, track the outcome of corrective action and obtain the responsible person's signature.
| Date/Shift | Affected location | Description of abnormality | Temporary measures | Shutdown required? | Performed by / Verified by |
