Gimbal Balancing Procedures for:
Archer 2 Series 305-7120-XX
1. Mount simulated camera weight (maximum payload capacity of sled recommended) onto sled and
place onto appropriate balance spud.
2. Fine tune fore-aft and left-right balance by adjusting fore/aft and side/side adjustment knobs on stage.
Verify balance using a bubble level attached atop the stage on a at surface.
3. Balance sled with an approximate 3 second drop time by ne tuning vertical position of gimbal.
4. With the front of the sled facing left, and the stage perpendicular to the curved gimbal handle, raise
the sled to the right to a horizontal position and release until it swings back to a vertical position.
5. Unit should always return to the established vertical position. If it does not, ne-tune the adjustment
pin screws (part# 804-7109) using included MSC-104218 spacing spanner screwdriver and repeat the
previous step.
6. To adjust pin screws remove bearing caps (815-7111) to access pin screws
7. Gimbal ring (305-7122) to yoke (305-7158) clearance should have zero end play but swing free, this is
adjusted by turning pin screws.
8. The adjustment pin screws should have some resistance when turning.
9. If the unit is leaning to the left of vertical: turn the right adjustment screw counter-clockwise and the
left adjustment screw clockwise in equal increments. If leaning right of vertical, reverse this procedure.
WARNING: turn these screws in small increments (1/16 of turn) as it will have a magnied affect when
drop time is set at 3 seconds or more.
10. Repeat drop test again. If unit does not repeat check to make sure all clamps, plates, camera and
whatever else might shift or become loose is stable and not shifting the balance point.
11. Re-install bearing cap covers, if not installing Volt.
