Completed By: / Completed on:
TASK / COMPLETED
Check tightness of all frame joints. Tighten screws if necessary.
Inspect black latch for damage. Replace if necessary.
Check all spring clips for smooth motion. Replace if necessary.
Check for wobble in turntable. Some wobble will be present always. If excessive, tighten by holding center retaining bolt in place using 3/8” allen wrench and tighten double locknuts using 15/16” ratchet if necessary. Do not over tighten or turntable will be difficult to rotate.
Check for tightness of all eyebolts. Tighten if necessary.
Check for tightness of all screws on drive frame and object frame. Tighten if necessary.
Check for sturdiness of base frame. Tighten screws if necessary.
Check condition of threads on eyebolt mounting nuts. Replace if necessary.
Check condition of grommets on object shields. If rust is present, coat with liquid electrical tape.
Check condition of object shields for missing grommets or any wear or holes. Repair or replace if necessary.
Check condition of leveling feet. If difficult to turn, remove and clean threads with water and if necessary, a wire brush. Replace leveling foot after threads have dried.
Check entire apparatus for signs of rust or other corrosion. If necessary, clean and coat surfaces to prevent.
Check tethering straps for smooth motion of ratchet mechanism. Replace if necessary.
Inspect cables on frequently used objects for fraying and damaged black nylon insulation. Replace if necessary.
