1. Lock out / tag out per LOT-014 (hydraulic + electrical isolation).
2. Verify zero pressure on accumulator; bleed to ≤2 psi.
3. Inspect ram seals for extrusion; replace if measured gap > 1.2 mm.
4. Sample hydraulic fluid; if particle count > ISO 18/16/13, schedule flush.
5. Cycle press three times at 30% tonnage; log pressure trace on Sheet 24.B.

Stop inheriting the last shift lead’s binder for extruder lockout.
Get a 1910.147 lockout/tagout procedure on every energy source behind the extruder, the hydraulic press, the Banbury mixer, the two-roll mill, the calendar stack, the granulator, and the dust collector — with the screw-rotation bleed, hydraulic accumulator pre-charge bleed, and barrel-heat cool-to-touch step named on the bench card; a mold + die + hydraulic-system PM schedule with per-shift clamp tonnage + accumulator pre-charge verification; a HAZCOM 1910.1200-aligned chemical-handling SOP library covering pigment + masterbatch dust, additive, isocyanate / curative, resin / gel-coat, solvent, and a dust-collection bag-change cadence that cross-cites your LOTO library; a per-press / per-extruder / per-mixer operator certification matrix; and an OSHA 300 with the hand-amputation / lockout-bypass / fume-exposure entries an auditor opens first. The program sits next to your machine shop documentation, your metal fab documentation, your forklift program, and your food & beverage plant documentation under one revision log, with every procedure cross-cited by tag — and back to your OSHA written-procedure library.
