Service the gantry tilt drive: lubricate the tilt detection unit and replace the power cylinder
This atom bundles the two tilt-drive maintenance tasks the source groups under one heading:
Tools & parts
| Item | Part number | Qty |
|---|---|---|
| Nichimori L grease | — | Adequate amount |
| Power cylinder (gantry tilt drive) | — | 1 |
Safety
Hazard: Foot placed on the stand base cover while tilting the gantry
Consequence: Foot caught between moving parts — injury
Avoidance: Never place a foot on the stand base cover during any gantry-tilt check in this task (Task A Step 3; Task B Steps 19, 21)
Hazard: Power cylinder disconnected/removed (Task B, Steps 9–12) with the tilt lock metal fitting not installed
Consequence: The tilt frame is no longer held by a drive member and can shift — pinch/crush injury or equipment damage
Avoidance: Install the tilt lock metal fitting (Step B6) before disconnecting the cylinder; leave it in place until the new cylinder is fully connected and torqued — remove it only at Step B18
Hazard: Removing the shaft itself instead of only its retaining metal fitting (Task B Step 8)
Consequence: Loses shaft engagement/alignment — extra rework to reseat it correctly
Avoidance: Remove only the M6 shaft-retaining metal fitting; do not extract the shaft at this step
Hazard: Replacing the power cylinder with the gantry tilted away from 0°
Consequence: Cover fit/clearance problems when the covers are removed and remounted
Avoidance: Set the tilt to 0° (Task B Step 1) before starting; if you must work off-0°, pay extra attention to cover fit during removal and remount
