Remove and mount the gantry rear-upper covers (left and right)
Remove the left and/or right rear-upper cover panel on the Activion16 gantry to gain service access, then remount it. The two panels can be worked independently — except for two shared M4 screws that fasten both covers together at once (see Safety/NOTICE below). You'll also do this as a required first step before removing the dome cover (§1.3.5), which explicitly depends on this procedure.
Tools & parts
| Item | Part number | Qty |
|---|---|---|
| Rear-upper cover, right | — | 1 |
| Rear-upper cover, left | — | 1 |
| M4 screws — right cover (2-M4*, asterisk-marked) | — | 2 |
| M4 screws — left cover (2-M4 + 1-M4) | — | 3 |
Safety
Hazard: Cover is unsupported once its screws are out — it rests loose on the hook plate
Consequence: Dropped or swinging cover panel — pinch injury or cosmetic/edge damage
Avoidance: Support the cover by hand as you lift it clear of the hook plate; do not let it hang or drop
Hazard: The 2 asterisk-marked M4 screws are shared fasteners between the left and right covers
Consequence: Reinstalling only one side without the shared screws leaves the adjacent cover loose or misaligned
Avoidance: Track the 2 marked (*) locations separately and tighten them together with both covers during mounting
