Collision Repair Frame Machine Calibration Verification Checklist [FREE PDF]

Frame machine calibration verification is a critical quality control process in collision repair, ensuring that straightening and alignment equipment meets manufacturer specifications and I-CAR procedural standards. Proper calibration directly impacts structural repair accuracy, which in turn affects vehicle occupant safety and crashworthiness as governed by OEM repair procedures. OSHA 29 CFR 1910 General Industry standards also mandate that shop equipment be maintained in safe operating conditi

Equipment Identification & Documentation

Verify machine identity, service history, and calibration documentation are current and accessible.

Is the manufacturer's calibration manual present and accessible at the machine?
Is the calibration log current with entries from the past 30 days?
Is the equipment asset tag or serial number label legible and intact?
Has the machine been serviced by an authorized technician within the manufacturer-specified interval?
Are all previous calibration discrepancy reports reviewed and resolved?

Electrical Safety & Lockout/Tagout Compliance

Inspect electrical components and verify lockout/tagout procedures are implemented before calibration.

Are all electrical panels, cords, and connections free from visible damage or fraying?
Is a written lockout/tagout procedure posted and followed before maintenance or calibration begins?
Are lockout/tagout devices (locks, tags, hasps) available and in serviceable condition?
Is the machine's main power switch or disconnect clearly labeled and accessible?
Are ground fault circuit interrupters (GFCIs) present on applicable outlets near the machine?

Anchoring & Clamping System Inspection

Evaluate the condition and accuracy of the anchoring, clamping, and pinch-weld hardware used to secure vehicles during repair.

Are all anchor clamps and tie-down chains free from cracks, deformation, or excessive wear?
Do anchor towers or post bases move freely along the frame rail without binding or play?
Are pinch-weld clamps rated for the vehicle weight being serviced?
Are all hydraulic hose connections on anchoring equipment leak-free and properly seated?
Is a photo of the anchoring setup taken and documented for this calibration session?

Measuring System Calibration & Accuracy

Verify that electronic or mechanical measuring systems produce results within acceptable tolerances.

Has the electronic measuring system been zeroed on a known flat reference surface prior to inspection?
Do measurement readings match the manufacturer's reference tolerance of ±1.5 mm or better?
Is the calibration tolerance reading for today within acceptable range (enter measured deviation in mm)?
Are all measuring arms and tram bars free from bends, dents, or damage affecting accuracy?
Is calibration software (if applicable) updated to the current OEM vehicle data version?
Is a test measurement recorded and attached to this calibration record?

Hydraulic Pulling & Ram System Inspection

Inspect hydraulic rams, hoses, gauges, and pulling towers for safe operation and calibration accuracy.

Are all hydraulic rams free from external leaks, scored cylinders, or pitting?
Does the hydraulic pressure gauge read within the manufacturer-specified operating range?
Is the current hydraulic fluid level within the specified operating range?
Are pulling chains and hooks rated to at least the machine's maximum pulling capacity?
Is the pulling tower or boom free from cracks, welds, or structural repairs not authorized by the manufacturer?

Workspace Safety & Housekeeping

Evaluate surrounding workspace conditions, aisle clearance, and general safety compliance in the frame bay.

Is the frame bay floor clear of tripping hazards, oil spills, and debris?
Is adequate lighting present throughout the frame bay to support accurate measurement?
Are fire extinguishers present, accessible, and within their annual inspection date?
Are all required PPE items (safety glasses, gloves, steel-toed footwear) available and in use?
Is there a minimum 36-inch clear aisle maintained around the frame machine on all sides?

Calibration Results & Sign-Off

Record final calibration determination, corrective actions taken, and authorized sign-off before returning machine to service.

Did this calibration verification result in a PASS determination for all critical measurement points?
Were any corrective actions required during this inspection session?
Please describe all corrective actions taken or deferred, including responsible party and target completion date.
Is this machine approved and returned to service following this calibration verification?
Has a calibration sticker with today's date and next due date been affixed to the machine?
Please attach any additional photos documenting calibration setup or identified deficiencies.
